The Ethers Project
==================
**EXPERIMENTAL**
[![npm (tag)](https://img.shields.io/npm/v/ethers/next)](https://www.npmjs.com/package/ethers/v/next)
[![Node.js CI](https://github.com/ethers-io/ethers.js/workflows/Node.js%20CI/badge.svg?branch=ethers-v5-beta)](https://github.com/ethers-io/ethers.js/actions?query=workflow%3A%22Node.js+CI%22)
This branch is the next release of ethers.js, which should
be promoted to the official release shortly.
A complete Ethereum wallet implementation and utilities in JavaScript (and TypeScript).
I would recommend it for most new projects and personally use
it for my own projects.
**Features:**
The [new documentation](https://docs-beta.ethers.io) is still a
bit sparse, but is coming along as well and will be complete
before the promotion to master.

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.

since they do not need to inspect the return types to unwrap simplified
functions.
Another use for this method is for error recovery. For example, if a
function result is an invalid UTF-8 string, the normal call using the
above meta-class function will throw an exception. This allows using the
Result access error to access the low-level bytes and reason for the error
allowing an alternate UTF-8 error strategy to be used.
Most developers should not require this.

_subsection: NonceManager @<experimental-noncemanager> @INHERIT<[[Signer]]>
The **NonceManager** is designed to manage the nonce for a Signer,
automatically increasing it as it sends transactions.
Currently the NonceManager does not handle re-broadcast. If you attempt
to send a lot of transactions to the network on a node that does not
control that account, the transaction pool may drop your transactions.
In the future, it'd be nice if the **NonceManager** remembered transactions
and watched for them on the network, rebroadcasting transactions that
appear to have been dropped.
Another future feature will be some sort of failure mode. For example, often
a transaction is dependent on another transaction being mined first.

The JSON-RPC API only provides a transaction hash as the response when a
transaction is sent, but the ethers Provider requires populating all details
of a transaction before returning it. For example, the gas price and gas limit
may be adjusted by the node or the nonce automatically included, in which case
the opaque transaction hash has discarded this.
To remedy this, the [[signer-jsonrpc]] immeidately queries the provider for
the details using the returned transaction hash to populate the [[provider-transactionresponse]]
To remedy this, the [[JsonRpcSigner]] immeidately queries the provider for

Some backends do not respond immediately and instead defer releasing the
details of a transaction it was responsible for signing until it is mined.
The **UncheckedSigner** does not populate any additional information and will
immediately return the result as a mock [[provider-transactionresponse]]-like

_subsection: Node-Specific Methods @<JsonRpcProvider--other>
Many methods are less common or specific to certain Ethereum Node implementations
(e.g. [Parity](link-parity) vs [Geth](link-geth). These include account and admin management,
debugging, deeper block and transaction exploration and other services (such as
Swarm and Whisper).
The [jsonRpcProvider.send](JsonRpcProvider-send) method can be used to access these.
- [All JSON-RPC methods](link-json-rpc) (including the less common methods) which most
Ethereum Nodes support.
- [Parity's Trace Module](link-parity-trace) can be used to trace and debug EVM
execcution of a transaction (requires custom configuration)
- [Geth's Debug Module](link-geth-debug) can be used to debug transactions and
internal cache state, etc.

The Web3Provider is meant to ease moving from a [web3.js based](link-web3)

_heading: ExternalProvider @<Web3Provider--ExternalProvider>
An **ExternalProvider** can be either one for the above mentioned Web3

An ExternalProvider must offer one of the following signatures, and the
first matching is used:
_property: externalProvider.request(request) => Promise<any>
This follows the [[link-eip-1193]] API signature.
The //request// should be a standard JSON-RPC payload, which should at
a minimum specify the ``method`` and ``params``.
The result should be the actual result, which differs from the Web3.js
response, which is a wrapped JSON-RPC response.
_property: externalProvider.sendAsync(request, callback) => void
This follows the [Web3.js Provider Signature](link-web3-send).
The //request// should be a standard JSON-RPC payload, which should at
a minimum specify the ``method`` and ``params``.
The //callback// should use the error-first calling semantics, so
``(error, result)`` where the result is a JSON-RPC wrapped result.
_property: externalProvider.send(request, callback) => void
This is identical to ``sendAsync``. Historically, this used a synchronous
web request, but no current browsers support this, so its use this way
was deprecated quite a long time ago

_subsection: Ethereum Naming Service (ENS) Methods @<Provider--ens-methods>
The [Ethereum Naming Service](link-ens) (ENS) allows a short and
easy-to-remember ENS Name to be atached to any set of keys
and values.
One of the most common uses for this is to use a simple name to
refer to an [Ethereum Address](address).
In the ethers API, nearly anywhere that accepts an address, an
ENS name may be used instead, which can simplify code and make
reading and debugging much simpler.
The provider offers some basic operations to help resolve and
work with ENS names.
_property: provider.lookupAddress(address) => Promise<string> @<Provider-lookupAddress> @SRC<providers/base-provider>
Performs a reverse lookup of the //address// in ENS using the

_code: example-ens.js

_section: AbiCoder @<AbiCoder> @SRC<abi:class.AbiCoder>
The **AbiCoder** is a collection of Coders which can be used to
encode and decode the binary data formats used to interoperate
between the EVM and higher level libraries.
Most developers will never need to use this class directly, since
the [[Interface]] class greatly simplifies these operations.
_subsection: Creating Instance @<AbiCoder--creating>
For the most part, there should never be a need to manually create
an instance of an [[AbiCoder]], since one is created with the
default coersion function when the library is loaded which can
be used universally.
This is likely only needed by those with specific needs to override
how values are coerced after they are decoded from their binary format.
_property: new ethers.utils.AbiCoder([coerceFunc]) @SRC<abi:constructor.AbiCoder>
Create a new AbiCoder instance, which will call the //coerceFunc// on every
decode, where the result of the call will be used in the Result.
The function signature is `(type, value)`, where the //type// is the string
describing the type and the //value// is the processed value from the underlying
Coder.
If the callback throws, the Result will contain a property that when accessed will
throw, allowing for higher level libraries to recover from data errors.
_property: ethers.utils.defaultAbiCoder => [[AbiCoder]]
An [[AbiCoder]] created when the library is imported which is used by
the [[Interface]].
_subsection: Coding Methods @<AbiCoder--methods>
_property: abiCoder.encode(types, values) => string<[[DataHexString]]> @<AbiCoder-encode> @SRC<abi/abi-coder>

_property: abiCoder.decode(types, data) => [[Result]] @<AbiCoder-decode> @SRC<abi/abi-coder>
Decode the //data// according to the array of //types//, each of which may be a

_section: Application Binary Interface @NAV<ABI>
An **Application Binary Interface** (ABI) is a collection of
[Fragments](Fragment) which specify how to interact with
various components of a Contract.
An [[Interface]] helps organize Fragments by type as well
as provides the functionality required to encode, decode and
work with each component.
Most developers will not require this low-level access to encoding
and decoding the binary data on the network and will most likely
use a [[Contract]] which provides a more convenient interface. Some
framework, tool developers or developers using advanced techniques
may find these classes and utilities useful.

_section: Best Practices @<best-practices>
_subsection: Network Changes
Handling a change in the network (e.g. Ropsten vs Mainnet) is
incredibly complex and a slight failure can at best make your
application seem confusing and at worst cause the loss of funds,
leak private data or misrepresent what an action performed.
Luckily, standard users should likely never change their networks
unless tricked to do so or they make a mistake.
This is a problem you mainly need to worry about for developers, and
most developers should understand the vast array of issues surrounding
a network change during application operation and will understand the
page reloading (which is already the default behaviour in many clients).
So, the best practice when a network change occurs is to simply
refresh the page. This should cause all your UI components to
reset to a known-safe state, including any banners and warnings
to your users if they are on an unsupported network.
This can be acomplished by using the following function:
_code: Automatically Refresh on Network Change @lang<script>
// Force page refreshes on network changes
{
// The "any" network will allow spontaneous network changes
const provider = new ethers.providers.Web3Provider(window.ethereum, "any");
provider.on("network", (newNetwork, oldNetwork) => {
// When a Provider makes its initial connection, it emits a "network"
// event with a null oldNetwork along with the newNetwork. So, if the
// oldNetwork exists, it represents a changing network
if (oldNetwork) {
window.location.reload();
}
});

_section: Security @<security>
_subsection: Key Derivation Functions @<security--pbkdf>
This is not specific to Ethereum, but is a useful technique
to understand and has some implications on User Experience.
Many people are concerned that encrypting and decrypting an
Ethereum wallet is quite slow and can take quite some time.
It is important to understand this is intentional and provides
much stronger security.
The algorithm usually used for this process is [scrypt](link-wiki-scrypt),
which is a memory and CPU intensive algorithm which computes
a key (fixed-length psudo-random series of bytes) for a given
password.
_heading: Why does it take so long?
The goal is to use as much CPU and memory as possible during
this algorithm, so that a single computer can only compute a
very small number of results for some fixed amount of time. To
scale up an attack, the attacker requires additional compuers,
increasing the cost to [brute-force attack](link-wiki-bruteforce)
to guess the password.
For example, if a user knows their correct password, this process
may take 10 seconds for them to unlock their own wallet and proceed.
But since an attacker does not know the password, they must guess; and
each guess also requires 10 seconds. So, if they wish to try guessing 1
million passwords, their computer would be completely tied up for 10
million seconds, or around 115 days.
Without using an algorithm like this, a user would be able
to log in instantly, however, 1 million passwords would only
take a few seconds to attempt. Even secure passwords would
likely be broken within a short period of time. There is no way
the algorithm can be faster for a legitimate user without also
being faster for an attacker.
_heading: Mitigating the User Experience
Rather than reducing the security (see below), a better practice is to make
the user feel better about waiting. The Ethers encryption and decryption
API allows the developer to incorporate a progress bar, by passing in a
progress callback which will be periodically called with a number between
0 and 1 indication percent completion.
In general a progress bar makes the experience feel faster, as well as
more comfortable since there is a clear indication how much (relative) time
is remaining. Additionally, using language like //"decrpyting..."// in
a progress bar makes a user feel like there time is not being //needlessly//
wasted.
_heading: Work-Arounds (not recommended)
There are ways to reduce the time required to decrypt an Ethereum JSON
Wallet, but please keep in mind that doing so **discards nearly all security**
on that wallet.
The scrypt algorithm is designed to be tuned. The main purpose of this is
to increase the difficulty as time goes on and computers get faster, but
it can also be tuned down in situations where the security is less important.
_code: @LANG<javascript>
// Our wallet object
const wallet = Wallet.createRandom();
// The password to encrypt with
const password = "password123";
// WARNING: Doing this substantially reduces the security
// of the wallet. This is highly NOT recommended.
// We override the default scrypt.N value, which is used
// to indicate the difficulty to crack this wallet.
const json = wallet.encrypt(password, {
scrypt: {
// The number must be a power of 2 (default: 131072)
N: 64
}
});

_section: Flatworm Docs
The //Flatworm Docs// rendering engine is designed to be **very**
simple, but provide enough formatting necessary for documenting
JavaScript libraries.
A lot of its inspiration came from [Read the Docs](link-rtd) and
the [Sphinx](link-sphinx) project.
_subsection: Fragments @<flatworm-fragments>
Each page is made up of fragments. A fragment is a [directive](flatworm-directive),
with an value and optional //link//, //extensions// and a body.
Many directives support [markdown](flatworm-markdown) in their value and body.
A fragment's body continues until another fragment is encountered.
_heading: Directive Format
_code: @lang<text>
\_DIRECTIVE: VALUE @<LINK> @EXTENSION<PARAMETER>
BODY
MORE BODY
DIRECTIVE: The directive name
VALUE: Optional; the value to pass to the directive
LINK: Optional; a name for internal linking
EXTENSION: Optional; extended directive functionality
PARAMETER: Optional; value to pass to extended directive functions
BODY: Optional; the directive body (certain directives only)
_heading: Flatworm Directives @<flatworm-directive>
_definition: **_section:** //TITLE//
A //section// has its **TITLE** in an H1 font. Sections are linked
to in //Table of Contents// and have a dividing line drawn above
them.
The body supports markdown.
There should only be one ``_section:`` per page.
**Extensions:** [@inherit](flatworm--ext-inherit), [@src](flatworm--ext-src), [@nav](flatworm--ext-nav), [@note](flatworm--ext-note)
_definition: **_subsection:** //TITLE//
A //subsection// has its **TITLE** in an H2 font. Subsections are linked
to in //Table of Contents// and have a dividing line drawn above
them.
The title and body support markdown.
**Extensions:** [@inherit](flatworm--ext-inherit), [@src](flatworm--ext-src), [@note](flatworm--ext-note)
_definition: **_heading:** //TITLE//
A //heading// has its **TITLE** in an H3 font.
The title and body support markdown.
**Extensions:** [@inherit](flatworm--ext-inherit), [@src](flatworm--ext-src), [@note](flatworm--ext-note)
_definition: **_definition:** //TERM//
A //definition// has its **TERM** in normal text and the body is
indented.
The title and body support markdown.
_definition: **_property:** //SIGNATURE//
A //property// has its JavaScript **SIGNATURE** formatted.
The body supports markdown and the return portion of the signature
support markdown links.
**Extensions:** [@src](flatworm--ext-src)
_definition: **_note:** //BANNER//
A //note// is placed in a blue bordered-box to draw attention to it.
The body supports markdown.
_definition: **_warning:** //BANNER//
A //warning// is placed in an orange bordered-box to draw attention to it.
The body supports markdown.
_definition: **_code:** //CAPTION//
Creates a [Code](flatworm--code) block.
The body does **not** support markdown, and will be output exactly as
is, with the exception of [Code Evaluation](flatworm--code-eval).
If a line begins with a ``"_"``, it should be escaped with a ``"\\"``.
**Extensions:** [@lang](flatworm--ext-lang)
_definition: **_table:** //FOOTER//
Creates a [Table](flatworm--table) structured according to the body.
Each cell support and variables support markdown.
**Extensions:** [@style](flatworm--ext-style)
_definition: **_toc:**
A //toc// injects a Table of Contents, loading each line of the
body as a filename and recursively loads the //toc// if present,
otherwise all the //sections// and //subsections//.
The body does **not** support markdown, as it is interpreted as
a list of files and directories to process.
_definition: **_null:**
A //null// is used to terminated a directive. For example, after
a //definition//, the bodies are indented, so a //null// can be
used to reset the indentation.
The body supports markdown.
_code: Example @lang<text>
\_section: Hello World @<link-main>
Body for section...
\_subsection: Some Example @<link-secondary>
Body for subsection...
\_heading: Large Bold Text @<link-here>
Body for heading...

_subsection: Markdown @<flatworm-markdown>
The markdown is simple and does not have the flexibility of
other dialects, but allows for **bold**, //italic//,
__underlined__, ``monospaced``, super^^script^^ and ~~strike~~
text, supporting [links](flatworm-markdown) and lists.
Lists are rendered as blocks of a body, so cannot be used within
a title or within another list.
_code: @lang<text>
**bold text**
//italic text//
__underlined text__
``monospace code``
^^superscript text^^
~~strikeout text~~
- This is a list
- With bullet points
- With a total of three items
This is a [Link to Ethereum](https://ethereum.org) and this
is an [Internal Link](some-link).
This is a self-titled link [[https://ethereumorg]] and this
[[some-link]] will use the title from its directives value.
_subsection: Code @<flatworm--code>
The code directive creates a monospace, contained block useful
for displaying code samples.
_heading: JavaScript Evaluation @<flatworm--code-eval>
For JavaScript files, the file is executed with some simple substitution.
A bare ``\/\/!`` on a line is replaced with the result of the last
statement. Building will fail if an error is thrown.
A bare ``\/\/!error`` is replaced with the throw error. Building will
fail if an error is not thrown.
Also any code included between the lines **``\/\/ <hide>``** and
**``\/\/ </hide>``** will be omitted from the output, which can be used
to setup variables.
_code: Code Evaluation Example @lang<text>
\_code: Result of Code Example @lang<javascript>
// <hide>
const url = require("url");
// </hide>
url.parse("https://www.ricmoo.com/").protocol
//!
url.parse(45)
//! error
// You want to assign (doesn't emit eval) AND display the value
const foo = 4 + 5;
// <hide>
foo
// </hide>
//!
_code: Result of Code Example @lang<javascript>
// <hide>
const url = require("url");
// </hide>
url.parse("https://www.ricmoo.com/").protocol
//!
url.parse(45)
//! error
// You want to assign (doesn't emit eval) AND display the value
const foo = 4 + 5;
// <hide>
foo
// </hide>
//!
_heading: Languages
The language can be specified using the [@lang extension](flatworm--ext-lang).
_table:
| **Language** | **Notes** |
| javascript | Syntax highlights and [evaluates](flatworm--code-eval) the JavaScipt |
| script | Same as ``javascript``, but does not evaluate the results |
| shell | Shell scripts or command-line |
| text | Plain text with no syntax highlighting |
_subsection: Tables @<flatworm--table>
The table directive consumes the entire body up until the next
directive. To terminate a table early to begin a text block,
use a **_null:** directive.
Each line of the body should be [Row Data](flatworm--table-row) or a
[Variable Declaration](flatworm--table-variable) (or continuation of
a //Variable Declaration//). Blank lines are ignored.
_heading: Row Data @<flatworm--table-row>
Each **Row Data** line must begin and end with a **``"|"``**, with each
gap representing the cell data, [alignment](flatworm--table-alignment)
with optional [column and row spanning](flatworm--table-spanning).
_heading: Alignment @<flatworm--table-alignment>
The alignment for a cell is determined by the whitespace surrounding the
cell data.
_table: Alignment Conditions (higher precedence listed first)
| **Alignment** | **Whitespace** |
| //Left// | 1 or fewer spaces before the content |
| //Right// | 1 or fewer spaces after the content |
| //Center// | 2 or more space **both** before and after the content |
_code: Alignment Example @lang<text>
\_table: Result of Alignment Example @style<compact>
| center |
| left |
|left |
| right |
| right|
_table: Result of Alignment Example @style<compact>
| center |
| left |
|left |
| right |
| right|
_heading: Row and Column Spanning @<flatworm--table-spanning>
A column may end its content with any number of **``"<"``** which indicates
how many //additional// columns to extend into.
If the cell content contains only a **``"^"``**, then the row above is
extended into this cell (into the same number of columns).
_code: Cell Spanning Example @lang<text>
\_table: Result of Cell Spanning Example @style<compact>
| (1x1) | (1x2) <| (2x1) |
| (2x2) <| (2x1) | ^ |
| ^ | ^ | (1x1) |
_table: Result of Cell Spanning Example @style<compact>
| (1x1) | (1x2) <| (2x1) |
| (2x2) <| (2x1) | ^ |
| ^ | ^ | (1x1) |
_heading: Styles @<flatworm--table-style>
The [@style extension](flatworm--ext-style) for a table can be used to control its
appearance.
_table:
| **Name** | **Width** | **Columns** |
| //minimal// | minimum size | best fit |
| //compact// | 40% | evenly spaced |
| //wide// | 67% | evenly spaced |
| //full// | 100% | evenly spaced |
_heading: Variables @<flatworm--table-variable>
Often the layout of a table is easier to express and maintain without
uneven or changing content within it. So the content can be defined
separately within a table directive using **variables**. A varaible
name must being with a letter and must only contain letters and numbers.
Variables are also useful when content is repeated throughout a table.
A variable is declared by starting a line with ``"$NAME:"``, which
consumes all lines until the next variable declaration or until the
next table row line.
A variable name must start with a letter and may consist of letters and
numbers. (i.e. ``/[a-z][a-z0-9]*/i``)
_code: Variables Example @lang<text>
\_table: Result of Variables Example
$Yes: This option is supported.
$No: This option is **not** supported
$bottom: This just represents an example of
what is possible. Notice that variable
content can span multiple lines.
| **Feature** | **Supported** |
| Dancing Monkey | $Yes |
| Singing Turtle | $No |
| Newt Hair | $Yes |

_subsection: Configuration @<flatworm-config>
Configuration is optional (but highly recommended) and may be either
a simple JSON file (config.json) or a JS file (config.js) placed in
the top of the source folder.
TODO: example JSON and example JS
_subsection: Extensions @<flatworm-extensions>
_heading: @inherit\< //markdown// > @<flatworm--ext-inherit>
Adds an inherits description to a directive. The //markdown// may contain links.
_heading: @lang\< //text// > @<flatworm--ext-lang>
Set the language a [code directive](flatworm--code) should be
syntax-highlighted for. If "javascript", the code will be evaluated.
_heading: @nav\< //text// > @<flatworm--ext-nav>
Sets the name in the breadcrumbs when not the current node.
_heading: @note\<// markdown// > @<flatworm--ext-note>
Adds a note to a directive. The //markdown// may contain links. If the directive
already has an @INHERIT extension, that will be used instead and the @NOTE will
be ignored.
_heading: @src\< //key// > @<flatworm--ext-src>
Calls the configuration ``getSourceUrl(key, VALUE)`` to get a URL which
will be linked to by a link next to the //directive//.
This extended directive function requires an advanced ``config.js`` [[flatworm-config]]
file since it requires a JavaScript function.

$Provider: A Provider (in ethers) is a class which provides an abstraction
for a connection to the Ethereum Network. It provides read-only
access to the Blockchain and its status.
$Signer: A Signer is a class which (usually) in some way directly or
indirectly has access to a private key, which can sign messages
and transactions to authorize the network to charge your account
ether to perform operations.
$Contract: A Contract is an abstraction which represents a connection to a
specific contract on the Ethereum Network, so that it can be
used like a normal JavaScipt object.

_subsection: Connecting to Ethereum: Metamask @<getting-started--connecting>
The quickest and easiest way to experiment and begin developing on
Ethereum is to use [[link-metamask]], which is a browser extension
that provides:
- A connection to the Ethereum network (a [[Provider]])
- Holds your private key and can sign thing (a [[Signer]])
_code: Connecting to Metamask @lang<script>
// A Web3Provider wraps a standard Web3 provider, which is
// what Metamask injects as window.ethereum into each page
const provider = new ethers.providers.Web3Provider(window.ethereum)
// The Metamask plugin also allows signing transactions to
// send ether and pay to change state within the blockchain.
// For this, we need the account signer...
const signer = provider.getSigner()
_heading: Querying the Blockchain @<getting-started--querying>
Once you have a [[Provider]], you have a read-only connection to the
blockchain, which can be used to query the current state, fetch historic
logs, look up deployed code and so on.
_code: Basic Queries @lang<javascript>
// Look up the current block number
provider.getBlockNumber()
//!
// Get the balance of an account (by address or ENS name)
balance = await provider.getBalance("ethers.eth")
//! async balance
// Often you will need to format the output for the user
// which prefer to see values in ether (instead of wei)
ethers.utils.formatEther(balance)
//!
// Or if a user enters a string in an input field, you may need
// to convert it from ether (as a string) to wei (as a BigNumber)
ethers.utils.parseEther("1.0")
//!
_heading: Writing to the Blockchain @<getting-started--sending>
_code: Sending Ether @lang<script>
// Send 1 ether to an ens name.
const tx = signer.sendTransaction({
to: "ricmoo.firefly.eth",
value: ethers.utils.parseEther("1.0")
});
_subsection: Contracts @<getting-started--contracts>
A Contract is an abstraction of program code which lives on the
Ethereum blockchain.
The [[Contract]] object makes it easier to use an on-chain
Contract as a normal JavaScript object, with the method all
mapped to encoding and decoding data for you.
If you are familiar with Databases, this is similar to ORM.
In order to communicate with the Contract on-chain, this class
needs to know what methods are available and how to encode and
decode the data, which is what the //Application Binary Interface// (API)
provides.
This class is a meta-class, which means its methods are constructed
at runtime, when you pass in the ABI to the constructor it uses that
to determine which methods to add.
While a on-chain Contract may have many methods available, you can safely ignore
any methods you don't need or use, providing a smaller subset of the ABI to
the contract.
An ABI often comes from the Solidity or Vyper compiler, but may also be
placed in the code easily using the Human-Readable ABI, which the following
examples use.
_code: Connecting to the DAI Contract @lang<javascript>
// We can use an ENS name for the contract address
const daiAddress = "dai.tokens.ethers.eth";
// The ERC-20 Contract ABI, which is a common contract interface
// for tokens (this is the Human-Readable ABI format)
const daiAbi = [
// Some simple details about the token
"function name() view returns (string)",
"function symbol() view returns (string)",
// Get the account balance
"function balanceOf(address) view returns (uint)",
// Send some of your tokens to someone else
"function transfer(address to, uint amount)",
// An event triggered whenever anyone transfers to someone else
"event Transfer(address indexed from, address indexed to, uint amount)"
];
// The Contract object
const daiContract = new ethers.Contract(daiAddress, daiAbi, provider);

// </hide>
// Get the ERC-20 token name
daiContract.name()

daiContract.symbol()
//!
// Get the balance of an address
balance = await daiContract.balanceOf("ricmoo.firefly.eth")
//! async balance
// Format the DAI for displaying to the user
ethers.utils.formatUnits(balance, 18)
//!
_heading: State Changing Methods @<getting-started--writing>
_code: Sending DAI @lang<script>
// The DAI Contract is currently connected to the Provider,
// which is read-only. We need to connect to a Signer, so
// that we can pay to send state-changing transactions.

// Each DAI has 18 decimal places

// Send 1 DAI to "ricmoo.firefly.eth"
