[][src]Crate ethers

Complete Ethereum & Celo library and wallet implementation.

ethers-rs is a port of ethers-js in Rust.

Note: All examples using await are assuming that they are called from inside an async function which is run in an async runtime. You are free to use any runtime and executor of your preference.

Quickstart: prelude

A prelude is provided which imports all the important data types and traits for you. Use this when you want to quickly bootstrap a new project.

use ethers::prelude::*;

Examples on how you can use the types imported by the prelude can be found in the examples directory of the repository and in the tests/ directories of each crate.

Quick explanation of each module in ascending order of abstraction


Contains all the necessary data structures for interacting with Ethereum, along with cryptographic utilities for signing and verifying ECDSA signatures on secp256k1. Bindings to the solidity compiler and ganache-cli are also provided as helpers. To simplify your imports, consider using the re-exported modules described in the next subsection.

utils, types, abi

These are re-exports of the utils, types and abi modules from the core crate


Ethereum nodes expose RPC endpoints (by default at localhost:8545). You can connect to them by using the Provider. The provider instance allows you to issue requests to the node which involve querying the state of Ethereum or broadcasting transactions with unlocked accounts on the node.


For security reasons, you typically do not want your private keys to be stored on the nodes. This module provides a Wallet type for loading a private key which can be connected with a Provider to produce a Client. The Client type is the object via which we recommend users with local private keys to use when interacting with Ethereum.


Interacting with Ethereum is not restricted to sending or receiving funds. It also involves using smart contracts, which can be thought of as programs with persistent storage.

Interacting with a smart contract requires broadcasting carefully crafted transactions where the data field contains the function's selector along with the arguments of the called function. This module provides the Contract and ContractFactory abstractions so that you do not have to worry about that. It also provides typesafe bindings via the abigen macro and the Abigen builder.
