Documentation

- [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.

Extension Packages

------------------



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.



- [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
