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.io/v5/api-keys/) in
|
|
the documentation.

Ancillary 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 packages, which can be included by those who need them, while not bloating
|
|
everyone else with packages they do not need.
|
|
|
|
We will keep a list of useful packages here.
