Documentation

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 in the documentation.
A special thanks to these services for providing community resources:
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 - A Provider which bundles multiple call requests into a single
callto reduce latency and backend request capacity - MulticoinPlugin - A Provider plugin to expand the support of ENS coin types
- GanaceProvider - A Provider for in-memory node instances, for fast debugging, testing and simulating blockchain operations
- Optimism Utilities - A collection of Optimism utilities
- LedgerSigner - A Signer to interact directly with Ledger Hardware Wallets
