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.
