labels: [ "enhancement" ]
body:
- type: markdown
attributes:
value: |
The best place to start a new feature request is by starting an [Idea discussion](https://github.com/ethers-io/ethers.js/discussions), to mull over the feature, discuss current options and think through the impact on the overall library.
Keep in mind that features increase the library size, and may require additional dependencies. Ethers strives to remain lean and the number of dependencies low, so many features may make more sense as ancillary packages.

Documentation
-------------
Browse the [documentation](https://docs.ethers.org) online:
- [Getting Started](https://docs.ethers.org/v6/getting-started/)
- [Full API Documentation](https://docs.ethers.org/v6/api/)
- [Various Ethereum Articles](https://blog.ricmoo.com/)
Providers
---------
Ethers works closely with an ever-growing list of third-party providers
to ensure getting started is quick and easy, by providing default keys
to each service.
These built-in keys mean you can use `ethers.getDefaultProvider()` and
start developing right away.
However, the API keys provided to ethers are also shared and are
intentionally throttled to encourage developers to eventually get
their own keys, which unlock many other features, such as faster
responses, more capacity, analytics and other features like archival
data.
When you are ready to sign up and start using for your own keys, please
check out the [Provider API Keys](https://docs.ethers.org/v5/api-keys/) in
the documentation.
A special thanks to these services for providing community resources:
- [Ankr](https://www.ankr.com/)
- [QuickNode](https://www.quicknode.com/)

- [Alchemy](https://dashboard.alchemyapi.io/signup?referral=55a35117-028e-4b7c-9e47-e275ad0acc6d)
Extension Packages
------------------
These are a number of packages not included in the umbrella `ethers ` npm package, and
additional packages are always being added. Often these packages are for specific
use-cases, so rather than adding them to the umbrella package, they are added as
ancillary packaged, which can be included by those who need them, while not bloating
everyone else with packages they do not need.
The `ethers` package only includes the most common and most core
functionality to interact with Ethereum. There are many other
packages designed to further enhance the functionality and experience.
We will keep a list of useful pacakges here.
- `@ethersproject/experimental`
- `@ethersproject/cli`
- `@ethersproject/ens`
- `@ethersproject/ledger`
- `@ethersproject/trezor`
Hacking
-------
This project uses a combination of Lerna and the ./admin scripts to manage
itself as a package of packages.
The umbrella package can be found in `packages/ethers`, and all packages in general
can be found in the `packages/` folder.
If you add new dependencies to any package (incuding internal dependencies), you will
need to re-create the internal links and re-build teh dependency graph::
```
/home/ethers> npm run bootstrap
```
To run a continuous build (with incremental TypeScript compilation):
```
/home/ethers> npm run auto-build
```
Finally, once you have made all your changes, you will need to bump the version
of packages that changed their NPM tarballs, as well as update the _version.*
and distribution builds (which is what we host on the CDN for browser-based
apps). To do this, run:
```
/home/ethers> npm run update-versions
```
Which will also list all packages that have changed along with the specifc files.
- [MulticallProvider](https://github.com/ethers-io/ext-provider-multicall) - A Provider which bundles multiple call requests into a single `call` to reduce latency and backend request capacity
- [MulticoinPlugin](https://github.com/ethers-io/ext-provider-plugin-multicoin) - A Provider plugin to expand the support of ENS coin types
- [GanaceProvider](https://github.com/ethers-io/ext-provider-ganache) - A Provider for in-memory node instances, for fast debugging, testing and simulating blockchain operations
- [Optimism Utilities](https://github.com/ethers-io/ext-utils-optimism) - A collection of Optimism utilities
- [LedgerSigner](https://github.com/ethers-io/ext-signer-ledger) - A Signer to interact directly with Ledger Hardware Wallets

# Security Policy
## Supported Versions
Maintaining multiple versions of the library is quite time consuming, so
the majority of the effort is focused on the latest major release.
If you do require a version outside of this chart updated with patch fix,
please [contact me](mailto:github@ricmoo.com).
| Version | Supported | Initial Release |
| ------- | ------------------------------------------ | ----------------- |
| 6.0.x | :white_check_mark: | 2023-02-02 |
| 5.0.x | :white_check_mark: (security updates) | 2020-06-12 |
| 4.0.x | :x: | 2018-10-01 |
| 3.0.x | :x: | 2018-03-05 |
| 2.2.x | :x: | 2018-01-11 |
| 2.1.x | :x: | 2017-05-22 |
| 2.0.x | :x: | 2017-04-05 |
| 1.0.x | :x: | 2016-08-23 |
| 0.0.x | :x: | 2016-07-14 |
## Reporting a Vulnerability
If you identify a security vulnerability with this library (or any dependency),
please do not hesitate to contact [github@ricmoo.com](mailto:github@ricmoo.com)
immediately.
I try to respond within the same day and will address any concern as quickly
as possible (including code fixes and publishing to NPM).
Any vulnerability will also be published to this file, along with credits,
pertinent information and links to fixes.

Admin Tool
==========
This tool is meant for admin tasks related to ethers.js.
Workflow
--------
After a new series of changes have been made and tested:
1. Run `npm run update-versions` to update and build all packages
2. Make any human-necessary changes to the automatically updated `CHANGELOG.md`
3. Run `git add .`
4. Run `git commit -S -m "Updated dist files."`
5. Run `git push`
6. Wait for TravisCI to complete running test cases
7. Run `npm run publish-all` to publish changed packages to NPM and tag GitHub
Update Dependency Graph: admin/cmds/update-depgraph
---------------------------------------------------
This is run as part of `npm run bootstrap` before running lerna bootstrap.
It recomputes the dependency graph and writes out the ordered
**tsconfig.project.json**
Update Versions: admin/cmds/update-versions
-------------------------------------------
Run using the `npm run update-versions`, which also cleans, bootstraps and
rebuilds the project before running the script.
For each package that has changed from the version in NPM (the published
tarballs are compared):
- Update the `version` in the **package.json**
- Update the `src.ts/_version.ts` (matches the **package.json**)
- Updates the `tarballHash` in the **package.json**
- Compiles the TypeScript (which updates the `_version.js` and `_version.d.js`)
- Lists all changed files (highlighting src.ts files)
Then:
- Generate the distribution files
- Update the `CHANGELOG.md`
Publish: admin/cmds/publish
---------------------------
Run using `npm run publish-all`. This requires a password for the secure
local config and the OTP for NPM.
- Publish (in dependency order) changed files to NPM
- The `gitHead` is updated in **only** the NPM **package.json**
- @TODO: Cut a release on GitHub including the relevant CHANGELOG entry

_title: API Providers
_section: API Providers
There are many services which offer a web API for accessing
the Ethereum Blockchain. These Providers allow connecting
to them, which simplifies development, since you do not need
to run your own instance or cluster of Ethereum nodes.
However, this reliance on third-party services can reduce
resiliance, security and increase the amount of required trust.
To mitigate these issues, it is recommended you use a
[Default Provider](get-default-provider).
_subsection: EtherscanProvider
The **EtherscanProvider** is backed by a combination of the various
[Etherscan APIs](https://etherscan.io/apis).
_property: provider.getHistory(address) => Array<History>
_subsection: InfuraProvider
The **InfuraProvider** is backed by the popular [INFURA](https://infura.io)
Ethereum service.
It supports Mainnet (homestead) and all common testnets (Ropsten, Rinkeby,
G&ouml;rli and Kovan).
_subsection: NodesmithProvider
The **NodesmithProvider** is backed by [Nodesmith](https://nodesmith.io).
It supports Mainnet (homestead) and all common testnets (Ropsten, Rinkeby,
G&ouml;rli and Kovan), as well as the Ethereum-like network [Aion](https://aion.network).
_subsection: AlchemyProvider
The **AlchemtProvider** is backed by [Alchemy](https://alchemyapi.io).
It supports Mainnet (homestead) and all common testnets (Ropsten, Rinkeby,
G&ouml;rli and Kovan).
_subsection: CloudfrontProvider
The CloudfrontProvider is backed by the
[Cloudflare Ethereum Gateway](https://developers.cloudflare.com/distributed-web/ethereum-gateway/).
It only supports Mainnet (homestead).

_title: Providers
_section: Providers
A **Provider** is an abstraction of a connection to the
Ethereum network, providing a concise, consistent interface
to standard Ethereum node functionality.
The ethers.js library provides several options which should
cover the vast majority of use-cases, but also includes the
necessary functions and classes for sub-classing if a more
custom configuration is necessary.
Most users should be able to simply use the [[get-default-provider]].
_subsection: Default Provider @<get-default-provider>
The default provider is the safest, easiest way to begin
developing on //Ethereum//, and it is also robust enough
for use in production.
It creates a [[provider-fallback]] connected to as many backend
services as possible. When a request is made, it is sent to
multiple backends simulatenously. As responses from each backend
are returned, they are checked that they agree. Once a quorum
has been reached (i.e. enough of the backends agree), the response
is provided to your application.
This ensures that if a backend has become out-of-sync, or if it
has been compromised that its responses are dropped in favor of
responses that match the majority.
_property: ethers.getDefaultProvider([ network ]) => [[provider]]
Returns a new Provider, backed by multiple services, connected
to //network//. Is no //network// is provided, **homestead**
(i.e. mainnet) is used.

Explain what a provider is...
_subsection: Accounts Methods
_property: provider.getBalance(address [ , blockTag = "latest" ]) => Promise<[[bignumber]]>
Returns the balance of //address// as of the //blockTag// block height.
_property: provider.getCode(address [ , blockTag = "latest" ]) => Promise<[[hexstring]]>
Returns the contract code of //address// as of the //blockTag// block height. If there is
no contract currently deployed, the result is ``0x``.
_property: provider.getStorageAt(address, position [ , blockTag = "latest" ]) => Promise<[[hexstring]]>
Returns the ``Bytes32`` value of the //position// at //address//, as of the //blockTag//.
_property: provider.getTransactionCount(address [ , blockTag = "latest" ]) => Promise<number>
Returns the number of transactions //address// has ever **sent**, as of //blockTag//.
This value is required to be the nonce for the next transaction from //address//
sent to the network.
_heading: Examples
_code: example-account.js
_subsection: Blocks Methods
_property: provider.getBlock(block) => Promise<[[provider-block]]>
Get the //block// from the network, where the ``result.transactions`` is a list
of transaction hashes.
_property: provider.getBlockWithTransactions(block) => Promise<[[provider-blocktxs]]>
Get the //block// from the network, where the ``result.transactions`` is
an Array of [[provider-transactionresponse]] objects.
_subsection: Ethereum Naming Service (ENS) Methods
TODO: Explain ENS here...
_property: provider.lookupAddress(address) => Promise<string>
Performs a reverse lookup of the //address// in ENS using the
//Reverse Registrar//. If the name does not exist, or the
forward lookup does not match, ``null`` is returned.
_property: provider.resovleName(name) => Promise<string>
Looks up the address of //name//. If the name is not owned, or
does not have a //Resolver// configured, or the //Resolver// does
not have an address configured, ``null`` is returned.
_heading: Examples
_code: example-ens.js
_subsection: Logs Methods
_property: provider.getLogs(filter) => Promise<Array<[[provider-log]]>>
Returns the Array of [[provider-log]] matching the //filter//.
Keep in mind that many backends will discard old events, and that requests
which are too broad may get dropped as they require too many resources to
execute the query.
_subsection: Network Status Methods
_property: provider.getNetwork() => Promise<[[provider-network]]>
Returns the [[provider-network]] this Provider is connected to.
_property: provider.getBlockNumber() => Promise<number>
Returns the block number (or height) of the most recently mined block.
_property: provider.getGasPrice() => Promise<[[bignumber]]>
Returns a //best guess// of the [[gas-price]] to use in a transaction.
_subsection: Transactions Methods
_property: provider.call(transaction [ , blockTag = "latest" ]) => Promise<[[hexstring]]>
Returns the result of executing the //transaction//, using //call//. A call
does not require any ether, but cannot change any state. This is useful
for calling gettings on Contracts.
_property: provider.estimateGas(transaction) => Promise<[[bignumber]]>
Returns an estimate of the amount of gas that would be required to submit //transaction//
to the network.
An estimate may not be accurate since there could be another transaction
on the network that was not accounted for, but after being mined affected
relevant state.
_property: provider.sendTransaction(transaction) => Promise<[[provider-transactionresponse]]>
Submits //transaction// to the network to be mined. The //transaction// **must** be signed,
and be valid (i.e. the nonce is correct and the account has sufficient balance to pay
for the transaction).
_property: provider.waitForTransaction(transactionHash) => Promise<[[provider-transactionreceipt]]>
Returns a Promise which will not resolve until //transactionHash// is mined.
_subsection: Event Emitter Methods
Explain events here...
_property: provider.on(eventName, listener) => this
Add a //listener// to be triggered for each //eventName//.
_property: provider.once(eventName, listener) => this
Add a //listener// to be triggered for only the next //eventName//,
at which time it be removed.
_property: provider.emit(eventName, ...args) => boolean
Notify all listeners of //eventName//, passing //args// to each listener. This
is generally only used internally.
_property: provider.off(eventName [ , listener ]) => this
Remove a //listener// for //eventName//. If no //listener// is provided,
all listeners for //eventName// are removed.
_property: provider.removeAllListeners([ eventName ]) => this
Remove all the listeners for //eventName//. If no //eventName// is provided,

Many functions and methods in this library take in values which
can be non-ambiguously and safely converted to a BigNumber. These
values can be sepcified as:
_definition: **//string//**
A [hexstring](hexstring) or a decimal string, either of which may
be negative.
_definition: **//BytesLike//**
A [BytesLike](byteslike) Object, such as an Array or Uint8Array.

_subsection: Notes
A few short notes on numbers...
_heading: Why can't I just use numbers?
The first problem many encounter when dealing with Ethereum is
the concept of numbers. Most common currencies are broken down
with very little granularity. For example, there are only 100
cents in a single dollar. However, there are 10^^18^^ **wei** in a
single **ether**.
JavaScript uses [IEEE 754 double-precision binary floating point](https://en.wikipedia.org/wiki/Double-precision_floating-point_format)
numbers to represent numeric values. As a result, there are //holes//
in the integer set after 9,007,199,254,740,991; which is
problematic for //Ethereum// because that is only around 0.009
ether (in wei), which means any value over that will begin to
experience rounding errors.
To demonstrate how this may be an issue in your code, consider:
_code: bignumber-ieee754.js
To remedy this, all numbers (which can be large) are stored
and manipulated as [Big Numbers](bignumber).
The functions [parseEther( etherString )](http://linkto) and
[formatEther( wei )](http://linkto) can be used to convert
between string representations, which are displayed to or entered
by the user and Big Number representations which can have
mathematical operations handled safely.

_subsection: Types
_heading: Bytes @<bytes>
A Bytes object is any object which is an
[Array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array) or
[TypedArray](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray) with
each value in the valid byte range (i.e. between 0 and 255 inclusive),
or is an Object with a ``length`` property where each indexed property
is in the valid byte range.
_heading: BytesLike @<byteslike>
A **BytesLike** can be either a [[bytes]] or a [[hexstring]].
_heading: Hexstring @<hexstring>
A **hexstring** is a string which has a ``0x`` prefix followed by
_heading: Signature @<signature>
- **r** and **s** --- The x co-ordinate of **r** and the **s** value of the signature
- **v** --- The parity of the y co-ordinate of **r**
- **_vs** --- The [compact representation](https://link_here) of the **(r, s)** and **v**
- **recoveryParam** --- The normalized (i.e. 0 or 1) value of **v**
_heading: SignatureLike @<signaturelike>
A **SignatureLike** is similar to a [[signature]], except redundant properties
may be omitted.
For example, if *_vs* is specified, **(r, s)** and **v** can be omitted. Likewise,
if **recoverParam** is provided, **v** can be omitted (as it can be computed).

_title: Display Logic and Input
_section: Display Logic and Input
When creating an Application, it is useful to convert between
user-friendly strings (usually displaying **ether**) and the
machine-readable values that contracts and maths depend on
(usually in **wei**).
For example, a Wallet may specify the balance in ether, and
gas prices in gwei for the User Interface, but when sending
a transaction, both must be specified in wei.
The [parseUnits](unit-conversion) will parse a string representing
ether, such as ``1.1`` into a [BigNumber](bignumber) in wei, and is
useful when a user types in a value, such as sending 1.1 ether.
The [formatUnits](unit-conversion) will format a [BigNumberish](bignumberish)
into a string, which is useful when displaying a balance.
_subsection: Units
_heading: Decimal Count
The //unit// specified may be an integer, which indicates how
many decimal place the unit has. For example, 1 ether has 18 decimal
places for wei, and if this library were used with Bitcoin, 1 BTC
has 8 decimal places for satoshis.
_heading: Named Units
In addition to specifying //unit// as a number of decimals, there
are several common units, which can be passed in as a string:
- **wei** --- 0
- **kwei** --- 3
- **mwei** --- 6
- **gwei** --- 9
- **szabo** --- 12
- **finney** --- 15
- **ether** --- 18

_title: Strings
_section: Strings

_subsection: Bytes32String @<bytes32-string>
A string in Solidity is length prefixed with its 256-bit (32 byte)
length, which means that even short strings require 2 words (64 bytes)
of storage.
In many cases, we deal with short strings, so instead of prefixing
the string with its length, we can null-terminate it and fit it in a
single word (32 bytes). Since we need only a single byte for the
null termination, we can store strings up to 31 bytes long in a
word.
_definition: **Note:**
Strings that are 31 __//bytes//__ long may contain fewer than 31 __//characters//__,
since UTF-8 requires multiple bytes to encode international characters.
_property: utils.parseBytes32String(aBytesLike) => string
Returns the decoded string represented by the ``Bytes32`` encoded data.
_property: utils.formatBytes32String(text) => string
Returns a ``bytes32`` string representation of //text//. If the
length of //text// exceeds 31 bytes, it will throw an error.
_subsection: UTF-8 Strings @<utf8-string>
_property: utils.toUtf8Bytes(text [ , form = current ] ) => Uint8Array
Returns the UTF-8 bytes of //text//, optionally normalizing it using the
[[unicode-normalization-form]] //form//.
_property: utils.toUtf8CodePoints(aBytesLike [ , form = current ] ) => Array<number>
Returns the Array of codepoints of //aBytesLike//, optionally normalizing it using the
[[unicode-normalization-form]] //form//.
**Note:** This function correctly splits each user-perceived character into
its codepoint, accounting for surrogate pairs. This should not be confused with
``string.split("")``, which destroys surrogate pairs, spliting between each UTF-16
codeunit instead.
_property: utils.toUtf8String(aBytesLike [ , ignoreErrors = false ] ) => string
Returns the string represented by the UTF-8 bytes of //aBytesLike//. This will
throw an error for invalid surrogates, overlong sequences or other UTF-8 issues,
unless //ignoreErrors// is specified.
_heading: UnicodeNormalizationForm @<unicode-normalization-form>
There are several [commonly used forms](https://en.wikipedia.org/wiki/Unicode_equivalence)
when normalizing UTF-8 data, which allow strings to be compared or hashed in a stable
way.
_property: utils.UnicodeNormalizationForm.current
Maintain the current normalization form.
_property: utils.UnicodeNormalizationForm.NFC
The Composed Normalization Form. This form uses single codepoints
which represent the fully composed character.
For example, the **&eacute;** is a single codepoint, ``0x00e9``.
_property: utils.UnicodeNormalizationForm.NFD
The Decomposed Normalization Form. This form uses multiple codepoints
(when necessary) to compose a character.
For example, the **&eacute;**
is made up of two codepoints, ``"0x0065"`` (which is the letter ``"e"``)
and ``"0x0301"`` which is a special diacritic UTF-8 codepoint which
indicates the previous character should have an acute accent.
_property: utils.UnicodeNormalizationForm.NFKC
The Composed Normalization Form with Canonical Equivalence. The Canonical
representation folds characters which have the same syntactic representation
but different semantic meaning.
For example, the Roman Numeral **I**, which has a UTF-8
codepoint ``"0x2160"``, is folded into the capital letter I, ``"0x0049"``.
_property: utils.UnicodeNormalizationForm.NFKD
The Decomposed Normalization Form with Canonical Equivalence.
See NFKC for more an example.
_definition: **Note:**
Only certain specified characters are folded in Canonical Equivalence, and thus
it should not be considered a method to acheive //any// level of security from
[homoglyph attacks](https://en.wikipedia.org/wiki/IDN_homograph_attack).

_section: Application Binary Interfaces @<docs-abi>
When interacting with any application, whether it is on Ethereum,
over the internet or within a compiled application on a computer
all information is stored and sent as binary data which is just a
sequence of bytes.
So every application must agree on how to encode and decode their
information as a sequence of bytes.
An **Application Binary Interface** (ABI) provides a way to describe
the encoding and decoding process, in a generic way so that a variety
of types and structures of types can be defined.
For example, a string is often encoded as a UTF-8 sequence of bytes,
which uses specific bits within sub-sequences to indicate emoji and
other special characters. Every implementation of UTF-8 must understand
and operate under the same rules so that strings work universally. In
this way, UTF-8 standard is itself an ABI.
When interacting with Ethereum, a contract received a sequence of bytes
as input (provided by sending a transaction or through a call) and
returns a result as a sequence of bytes. So, each Contract has its own
ABI that helps specify how to encode the input and how to decode the output.
It is up to the contract developer to make this ABI available. Many
Contracts implement a standard (such as ERC-20), in which case the
ABI for that standard can be used. Many developers choose to verify their
source code on Etherscan, in which case Etherscan computes the ABI and
provides it through their website (which can be fetched using the ``getContract``
method). Otherwise, beyond reverse engineering the Contract there is
not a meaningful way to extract the contract ABI.
_subsection: Call Data Representation
When calling a Contract on Ethereum, the input data must be encoded
according to the ABI.
The first 4 bytes of the data are the **method selector**, which is
the keccak256 hash of the normalized method signature.
Then the method parameters are encoded and concatenated to the selector.
All encoded data is made up of components padded to 32 bytes, so the length
of input data will always be congruent to ``4 mod 32``.
The result of a successful call will be encoded values, whose components
are padded to 32 bytes each as well, so the length of a result will always
be congruent to ``0 mod 32``, on success.
The result of a reverted call will contain the **error selector** as the
first 4 bytes, which is the keccak256 of the normalized error signature,
followed by the encoded values, whose components are padded to 32 bytes
each, so the length of a revert will be congruent to ``4 mod 32``.
The one exception to all this is that ``revert(false)`` will return a
result or ``0x``.
_subsection: Event Data Representation
When an Event is emitted from a contract, there are two places data is
logged in a Log: the **topics** and the **data**.
An additonal fee is paid for each **topic**, but this affords a topic
to be indexed in a bloom filter within the block, which allows efficient
filtering.
The **topic hash** is always the first topic in a Log, which is the
keccak256 of the normalized event signature. This allows a specific
event to be efficiently filtered, finding the matching events in a block.
Each additional **indexed** parameter (i.e. parameters marked with
``indexed`` in the signautre) are placed in the topics as well, but may be
filtered to find matching values.
All non-indexed parameters are encoded and placed in the **data**. This
is cheaper and more compact, but does not allow filtering on these values.
For example, the event ``Transfer(address indexed from, address indexed to, uint value)``
would require 3 topics, which are the topic hash, the ``from`` address
and the ``to`` address and the data would contain 32 bytes, which is
the padded big-endian representation of ``value``. This allows for
efficient filtering by the event (i.e. ``Transfer``) as well as the ``from``
address and ``to`` address.
_subsection: Deployment
When deploying a transaction, the data provided is treated as **initcode**,
which executes the data as normal EVM bytecode, which returns a sequence
of bytes, but instead of that sequence of bytes being treated as data that
result is instead the bytecode to install as the bytecode of the contract.
The bytecode produced by Solidity is designed to have all constructor
parameters encoded normally and concatenated to the bytecode and provided
as the ``data`` to a transaction with no ``to`` address.

Many things are the way they are for good (at the time, at least) reasons,
but I always welcome criticism, and am completely willing to have my mind
changed on things.
So, pull requests are always welcome, but please keep a few points in mind:
- Backwards-compatibility-breaking changes will not be accepted; they may be
considered for the next major version
- Security is important; adding dependencies require fairly convincing
arguments as to why
- The library aims to be lean, so keep an eye on the dist/ethers.min.js

_heading: Building the Documentation
Currently, the documentation is built using an experimental v2 of the
Flatworm documentation system, a system originally specifically made
to maintain the Ethers documentation.
The new ``tsdocs`` branch has the ability to parse ``jsdocs`` from
from TypeScript source files to create an API reference.
_code: Building with the v2 Flatworm @lang<shell>
# Clone the repo
/home/ricmoo> git clone https://github.com/ricmoo/flatworm.git
/home/ricmoo> cd flatworm
# Check out the tsdocs branch
/home/ricmoo/flatworm> git checkout tsdocs
# Install the necessary dependencies
/home/ricmoo/flatworm> npm install
# Ready to build the docs; output to a folder ./output/
/home/ricmoo/flatworm> node lib/cli-test PATH_TO_WRM_ROOT
Eventually the code for the v2 branch will be cleaned up, and it
will be much easier to include as a ``devDependency`` for Ethers.
In the meantime, expect new changes to be made frequently to the
``tsdocs`` branch, so for stability you may wish to checkout a
specific hash.
_subsection: Fixing Bugs @<about-contrib-bugs>
In general the **only** files you should ever include in a PR are:
- TypeScript source: ``/src.ts/*\*.ts``
Do not include a ``package.json`` with the updated ``tarballHash``
or ``version``, and do not include any generated files in your PR.
A bug fix **must not** modify anything requiring a minor version
bump (see [[about-contrib-feature]]), such as changing a method
signature or altering the exports.
_subsection: Adding Features @<about-contrib-feature>
Contributing new features usually require a deeper understanding
of the internal interactions with Ethers and its components, and
generally requires a minor version bump.
When making any of the following changes, you must first open a
[[link-discussion]] as the minor version will need to be bumped.
- any signature change (such as adding a parameter, changing a
parameter type, changing the return type)
- adding any new export; such as a class, function or constants
- adding any method to any class
- changing any ``exports`` property within the ``package.json``
Changes of this sort should not be made without serious consideration
and discussion.

_section: Signing @<cookbook-signing>
Signing content and providing the content and signature to a
Contract allows on-chain validation that a signer has access
to the private key of a specific address.
The ecrecover algorithm allows the public key to be determined
given some message digest and the signature generated by the
private key for that digest. From the public key, the address
can then be computed.
How a digest is derived depends on the type of data being
signed and a variety of encoding formats are employed. Each
format is designed to ensure that they do not collide, so for
example, a user **cannot** be tricked into signing a message
which is actually a valid transaction.
For this reason, most APIs in Ethereum do not permit signing a
raw digest, and instead require a separate API for each format
type and require the related data be specified, protecting the
user from accidentally authorizing an action they didn't intend.
_subsection: Messages @<cookbook-signing-messages>
A signed message can be any data, but it is generally recommended
to use human-readable text, as this is easier for a user to
verify visually.
This technique could be used, for example, to sign into a service
by using the text ``"I am signing into ethers.org on 2023-06-04 12:57pm"``.
The user can then see the message in MetaMask or on a Ledger
Hardware Wallet and accept that they wish to sign the message which
the site can then authenticate them with. By providing a timestamp
the site can ensure that an older signed message cannot be used again
in the future.
The format that is signed uses [[link-eip-191]] with the
**personal sign** version code (``0x45``, or ``"E"``).
For those interested in the choice of this prefix, signed messages
began as a Bitcoin feature, which used ``"\\x18Bitcoin Signed Message:\\n"``,
which was a Bitcoin var-int length-prefixed string (as ``0x18`` is 24,
the length of ``"Bitcoin Signed Message:\\n"``.). When Ethereum adopted
the similar feature, the relevant string was ``"\\x19Ethereum Signed Message:\\n"``.
In one of the most brilliant instances of technical retcon-ing,
since 0x19 is invalid as the first byte of a transaction (in [[link-rlp]] it
indicates a single byte of value 25), the initial byte ``\\x19`` has
now been adopted as a prefix for //some sort of signed data//,
where the second byte determines how to interpret that data. If the
second byte is 69 (the letter ``"E"``, as in
``"Ethereum Signed Message:\\n"``), then the format is a
the above prefixed message format.
So, all existing messages, tools and instances using the signed
message format were already EIP-191 compliant, long before the
standard existed or was even conceived and allowed for an extensible
format for future formats (of which there now a few).
Anyways, the necessary JavaScript and Solidity are provided below.
_code: JavaScript @lang<javascript>

_section: Getting Started
This is a very short introduction to Ethers, but covers many of the
most common operations that developers require and provides a
starting point for those newer to Ethereum.
_subsection: Installing
_heading: Getting Ethers
The various Classes and Functions are available to be imported
manually from sub-packages under the
[@ethersproject](https://www.npmjs.com/search?q=%40ethersproject%2F)
but for most projects, the umbrella package is the easiest way to
get started.
If using NPM, you must first install Ethers.
_code: installing.txt
_code: installing via NPM @lang<shell>
# Install ethers
/home/ricmoo/test-ethers> npm install ethers
_null:
Everything in Ethers is exported from its root as well as on the ``ethers``
object. There are also ``exports`` in the ``package.json`` to facilitate
more fine-grained importing.
Generally this documentation will presume all exports from ethers
have been imported in the code examples, but you may import the
necessary objects in any way you wish.
_code: importing in Node.js @lang<script>
// Import everything
import { ethers } from "ethers";
// Import just a few select items
import { BrowserProvider, parseUnits } from "ethers";
// Import from a specific export
import { HDNodeWallet } from "ethers/wallet";
_code: importing ESM in a browser @lang<script>
<script type="module">
import { ethers } from "https://cdnjs.cloudflare.com/ajax/libs/ethers/6.7.0/ethers.min.js";
// Your code here...
</script>
_subsection: Importing
_subsection: Some Common Terminology @<starting-glossary>
_heading: Node.js
To begin, it is useful to have a basic understanding of the types of
objects available and what they are responsible for, at a high level.
_code: importing-node.source
_heading: Provider
_heading: Web Browser
A [[Provider]] is a read-only connection to the blockchain, which allows
querying the blockchain state, such as account, block or transaction details,
querying event logs or evaluating read-only code using call.
It is generally better practice (for security reasons) to copy the
[ethers library](https://cdn.ethers.io/lib/ethers-5.0.min.js) to
your own webserver and serve it yourself.
If you are coming from Web3.js, you are used to a **Provider** offering
both read and write access. In Ethers, all write operations are further
abstracted into another Object, the **Signer**.
For quick demos or prototyping though, it can be loaded in your
Web Applications from our CDN.
_heading: Signer
A [[Signer]] wraps all operations that interact with an account. An
account generally has a private key located //somewhere//, which can be
used to sign a variety of types of payloads.
The private key may be located in memory (using a [[Wallet]]) or
protected via some IPC layer, such as MetaMask which proxies interaction
from a website to a browser plug-in, which keeps the private key out of
the reach of the website and only permits interaction after requesting
permission from the user and receiving authorization.
_heading: Transaction
To make any state changes to the blockchain, a transaction is required,
which requires a fee to be paid, where the fee covers the associated costs
with executing the transaction (such as reading the disk and performing
maths) and storing the updated information.
If a transaction reverts, a fee must still be paid, since the validator
still had to expend resources to try running the transaction to determine
that it reverted and the details of its failure are still be recorded.
Transactions include sending ether from one user to another, deploying
a **Contract** or executing a state-changing operation against a
**Contract**.
_heading: Contract
A [[Contract]] is a program that has been deployed to the blockchain,
which includes some code and has allocated storage which it can read
from and write to.
It may be read from when it is connected to a [[Provider]] or
state-changing operations can be called when connected to a [[Signer]].
_heading: Receipt
Once a **Transaction** has been submitted to the blockchain, it is placed
in the memory pool (mempool) until a validator decides to include it.
A transaction's changes are only made once it has been included in the
blockchain, at which time a receipt is available, which includes details
about the transaction, such as which block it was included in, the actual
fee paid, gas used, all the events that it emitted and whether it was
successful or reverted.
_subsection: Connecting to Ethereum @<starting-connecting>
This very first thing needed to begin interacting with the blockchain is
connecting to it using a [[Provider]].
_heading: MetaMask (and other injected providers)
The quickest and easiest way to experiment and begin developing
on Ethereum is to use [[link-metamask]], which is a browser
extension that injects objects into the ``window``, providing:
- read-only access to the Ethereum network (a [[Provider]])
- authenticated write access backed by a private key (a [[Signer]])
When requesting access to the authenticated methods, such as
sending a transaction or even requesting the private key address,
MetaMask will show a pop-up to the user asking for permission.
_code: @lang<script>
let signer = null;
let provider;
if (window.ethereum == null) {
// If MetaMask is not installed, we use the default provider,
// which is backed by a variety of third-party services (such
// as INFURA). They do not have private keys installed,
// so they only have read-only access
console.log("MetaMask not installed; using read-only defaults")
provider = ethers.getDefaultProvider()
} else {
// Connect to the MetaMask EIP-1193 object. This is a standard
// protocol that allows Ethers access to make all read-only
// requests through MetaMask.
provider = new ethers.BrowserProvider(window.ethereum)
// It also provides an opportunity to request access to write
// operations, which will be performed by the private key
// that MetaMask manages for the user.
signer = await provider.getSigner();
}
_heading: Custom RPC Backend
If you are running your own Ethereum node (e.g. [[link-geth]])
or using a custom third-party service (e.g. [[link-infura]]),
you can use the [[JsonRpcProvider]] directly, which communicates
using the [[link-jsonrpc]] protocol.
When using your own Ethereum node or a developer-base blockchain,
such as Hardhat or Ganache, you can get access to the accounts with
[[JsonRpcProvider-getSigner]].
_code: connecting to a JSON-RPC URL @lang<script>
// If no %%url%% is provided, it connects to the default
// http://localhost:8545, which most nodes use.
provider = new ethers.JsonRpcProvider(url)
// Get write access as an account by getting the signer
signer = await provider.getSigner()
_subsection: User Interaction @<starting-display>
All units in Ethereum tend to be integer values, since dealing with
decimals and floating points can lead to imprecise and non-obvious
results when performing mathematic operations.
As a result, the internal units used (e.g. wei) which are suited for
machine-readable purposes and maths are often very large and not
easily human-readable.
For example, imagine dealing with dollars and cents; you would show
values like ``"$2.56"``. In the blockchain world, we would keep all
values as cents, so that would be ``256`` cents, internally.
So, when accepting data that a user types, it must be converted from
its decimal string representation (e.g. ``"2.56"``) to its lowest-unit
integer representation (e.g. ``256``). And when displaying a value to
a user the opposite operation is necessary.
In Ethereum, //one ether// is equal to ``10 *\* 18`` wei and //one gwei//
is equal to ``10 *\* 9`` wei, so the values get very large very quickly,
so some convenience functions are provided to help convert between
representations.
_code: @lang<javascript>
// Convert user-provided strings in ether to wei for a value
eth = parseEther("1.0")
//_result:
// Convert user-provided strings in gwei to wei for max base fee
feePerGas = parseUnits("4.5", "gwei")
//_result:
// Convert a value in wei to a string in ether to display in a UI
formatEther(eth)
//_result:
// Convert a value in wei to a string in gwei to display in a UI
formatUnits(feePerGas, "gwei")

Once you have a [[Provider]], you have a read-only connection to
the data on the blockchain. This can be used to query the current
account state, fetch historic logs, look up contract code and so on.
_code: @lang<javascript>
//_hide: provider = new InfuraProvider();
// Look up the current block number (i.e. height)
await provider.getBlockNumber()
//_result:
// Get the current balance of an account (by address or ENS name)
balance = await provider.getBalance("ethers.eth")
//_result:
// Since the balance is in wei, you may wish to display it
// in ether instead.
formatEther(balance)
//_result:
// Get the next nonce required to send a transaction
await provider.getTransactionCount("ethers.eth")
//_result:
_heading: Sending Transactions
To write to the blockchain you require access to a private key
which controls some account. In most cases, those private keys
are not accessible directly to your code, and instead you make
requests via a [[Signer]], which dispatches the request to a
service (such as [[link-metamask]]) which provides strictly
gated access and requires feedback to the user to approve or
reject operations.
_code: @lang<script>
//_hide: provider = new JsonRpcProvider("http:/\/localhost:8545")
//_hide: provider.resolveName = () => "0x643aA0A61eADCC9Cc202D1915D942d35D005400C";
//_hide: signer = new Wallet(id("test"), provider);
// When sending a transaction, the value is in wei, so parseEther
// converts ether to wei.
tx = await signer.sendTransaction({
to: "ethers.eth",
value: parseEther("1.0")
});
//_result:
// Often you may wish to wait until the transaction is mined
receipt = await tx.wait();
//_result:
_subsection: Contracts @<starting-contracts>
A **Contract** is a meta-class, which means that its definition
its derived at run-time, based on the ABI it is passed, which then
determined what methods and properties are available on it.
_heading: Application Binary Interface (ABI)
Since all operations that occur on the blockchain must be encoded
as binary data, we need a concise way to define how to convert
between common objects (like strings and numbers) and its binary
representation, as well as encode the ways to call and interpret
the Contract.
For any method, event or error you wish to use, you must include a
[[Fragment]] to inform Ethers how it should encode the request and
decode the result.
Any methods or events that are not needed can be safely excluded.
There are several common formats available to describe an ABI. The
Solidity compiler usually dumps a JSON representation but when typing
an ABI by hand it is often easier (and more readable) to use the
human-readable ABI, which is just the Solidity signature.
_code: simplified ERC-20 ABI @lang<script>
abi = [
"function decimals() view returns (string)",
"function symbol() view returns (string)",
"function balanceOf(address addr) view returns (uint)"
]
// Create a contract
contract = new Contract("dai.tokens.ethers.eth", abi, provider)
_heading: Read-only methods (i.e. ``view`` and ``pure``)
A read-only method is one which cannot change the state of the
blockchain, but often provide a simple interface to get important
data about a Contract.
_code: reading the DAI ERC-20 contract @lang<javascript>
// The contract ABI (fragments we care about)
abi = [
"function decimals() view returns (uint8)",
"function symbol() view returns (string)",
"function balanceOf(address a) view returns (uint)"
]
// Create a contract; connected to a Provider, so it may
// only access read-only methods (like view and pure)
contract = new Contract("dai.tokens.ethers.eth", abi, provider)
// The symbol name for the token
sym = await contract.symbol()
//_result:
// The number of decimals the token uses
decimals = await contract.decimals()
//_result:
// Read the token balance for an account
balance = await contract.balanceOf("ethers.eth")
//_result:
// Format the balance for humans, such as in a UI
formatUnits(balance, decimals)
//_result:
_heading: State-changing Methods
_code: change state on an ERC-20 contract @lang<script>
abi = [
"function transfer(address to, uint amount)"
]
// Connected to a Signer; can make state changing transactions,
// which will cost the account ether
contract = new Contract("dai.tokens.ethers.eth", abi, signer)
// Send 1 DAI
amount = parseUnits("1.0", 18);
// Send the transaction
tx = await contract.transfer("ethers.eth", amount)
//_result: @TODO
// Currently the transaction has been sent to the mempool,
// but has not yet been included. So, we...
// ...wait for the transaction to be included.
await tx.wait()
//_result: @TODO
_code: forcing a call (simulation) of a state-changing method @lang<javascript>
abi = [
"function transfer(address to, uint amount) returns (bool)"
]
// Connected to a Provider since we only require read access
contract = new Contract("dai.tokens.ethers.eth", abi, provider)
amount = parseUnits("1.0", 18)
// There are many limitations to using a static call, but can
// often be useful to preflight a transaction.
await contract.transfer.staticCall("ethers.eth", amount)
//_result:
// We can also simulate the transaction as another account
other = new VoidSigner("0x643aA0A61eADCC9Cc202D1915D942d35D005400C")
contractAsOther = contract.connect(other.connect(provider))
await contractAsOther.transfer.staticCall("ethers.eth", amount)
//_result:
_heading: Listening to Events
When adding event listeners for a named event, the event parameters
are destructed for the listener.
There is always one additional parameter passed to a listener, which
is an [[EventPayload]], which includes more information about the event
including the filter and a method to remove that listener.
_code: listen for ERC-20 events @lang<script>
abi = [
"event Transfer(address indexed from, address indexed to, uint amount)"
]
// Create a contract; connected to a Provider, so it may
// only access read-only methods (like view and pure)
contract = new Contract("dai.tokens.ethers.eth", abi, provider)
// Begin listening for any Transfer event
contract.on("Transfer", (from, to, _amount, event) => {
const amount = formatEther(_amount, 18)
console.log(`${ from } => ${ to }: ${ amount }`);
// The `event.log` has the entire EventLog
// Optionally, stop listening
event.removeListener();
});
// Same as above
contract.on(contract.filters.Transfer, (from, to, amount, event) => {
// See above
})
// Listen for any Transfer to "ethers.eth"
filter = contract.filters.Transfer("ethers.eth")
contract.on(filter, (from, to, amount, event) => {
// `to` will always be equal to the address of "ethers.eth"
});
// Listen for any event, whether it is present in the ABI
// or not. Since unknown events can be picked up, the
// parameters are not destructed.
contract.on("*", (event) => {
// The `event.log` has the entire EventLog
});
_heading: Query Historic Events
When querying within a large range of blocks, some backends may
be prohibitively slow, may return an error or may truncate the
results without any indication. This is at the discretion of each
backend.
_code: query historic ERC-20 events @lang<javascript>
abi = [
"event Transfer(address indexed from, address indexed to, uint amount)"
]
// Create a contract; connected to a Provider, so it may
// only access read-only methods (like view and pure)
contract = new Contract("dai.tokens.ethers.eth", abi, provider)
// Query the last 100 blocks for any transfer
filter = contract.filters.Transfer
events = await contract.queryFilter(filter, -100)
// The events are a normal Array
events.length
//_result:
// The first matching event
events[0]
//_result:
// Query all time for any transfer to ethers.eth
filter = contract.filters.Transfer("ethers.eth")
events = await contract.queryFilter(filter)
// The first matching event
events[0]
//_result:
_subsection: Signing Messages @<starting-signing>
A private key can do a lot more than just sign a transaction to authorize
it. It can also be used to sign other forms of data, which are then able
to be validated for other purposes.
For example, signing **a message** can be used to prove ownership of an
account which a website could use to authenticate a user and log them in.
_code: @lang<javascript>
// Our signer; Signing messages does not require a Provider
signer = new Wallet(id("test"))
//_result:
message = "sign into ethers.org?"
// Signing the message
sig = await signer.signMessage(message);
//_result:
// Validating a message; notice the address matches the signer
verifyMessage(message, sig)
//_result:
_null:
Many other more advanced protocols built on top of signed messages are
used to allow a private key to authorize other users to transfer their
tokens, allowing the transaction fees of the transfer to be paid by
someone else.

_section: What is ethers?
The ethers.js library aims to be a complete and compact library
for interacting with the Ethereum Blockchain and its ecosystem.
The ethers.js library aims to be a complete and compact library for
interacting with the Ethereum Blockchain and its ecosystem. It was
originally designed for use with [ethers.io](https://ethers.io/) and
has since expanded into a much more general-purpose library.
_subsection: Features
- Keep your private keys in your client, **safe** and sound
- Import and export **JSON wallets** (Geth, Parity and crowdsale)
- Import and export BIP 39 **mnemonic phrases** (12 word backup
phrases) and HD Wallets (English, Italian, Japanese, Korean,
Simplified Chinese, Traditional Chinese; more coming soon)
- Meta-classes create JavaScript objects from any contract ABI,
including **ABIv2** and **Human-Readable ABI**
- Connect to Ethereum nodes over
[JSON-RPC](https://github.com/ethereum/wiki/wiki/JSON-RPC),
[INFURA](https://infura.io/),
[Etherscan](https://etherscan.io/),
[Nodesmith](https://nodesmith.io),
[Alchemy](https://alchemyapi.io),
or [MetaMask](https://metamask.io/).
- **ENS names** are first-class citizens; they can be used
anywhere an Ethereum addresses can be used
- **Tiny** (~88kb compressed; 284kb uncompressed)
- **Complete** functionality for all your Ethereum needs
- Extensive [documentation](https://docs.ethers.io/)
- Large collection of **test cases** which are maintained and added to
- Fully **TypeScript** ready, with definition files and full
TypeScript source
- **MIT License** (including //ALL// dependencies); completely open
source to do with as you please
It is often used to create decentralized applications (dapps),
wallets (such as [[link-metamask]] and [[link-tally]]) and
other tools and simple scripts that require reading and writing
to the blockchain.
