Github Actions Telegram Chat Crates.io

Documentation

Extensive documentation and examples are available here.

Alternatively, you may clone the repository and run cd ethers/ && cargo doc --open

You can also run any of the examples by executing: cargo run -p ethers --example <name>

Add ethers-rs to your repository

[dependencies]

ethers = { git = "https://github.com/gakonst/ethers-rs" }

Running the tests

Tests require the following installed:

  1. solc. We also recommend using solc-select for more flexibility.
  2. ganache-cli

In addition, it is recommended that you set the ETHERSCAN_API_KEY environment variable for the abigen via Etherscan tests. You can get one here.

EVM-compatible chains support

There are many chains live which are Ethereum JSON-RPC & EVM compatible, but do not yet have support for EIP-2718 Typed Transactions. This means that transactions submitted to them by default in ethers-rs will have invalid serialization. To address that, you must use the legacy feature flag:

[dependencies]

ethers = { git = "https://github.com/gakonst/ethers-rs", features = ["legacy"] }

Celo Support

Celo support is turned on via the feature-flag celo:

[dependencies]

ethers = { git = "https://github.com/gakonst/ethers-rs", features = ["celo"] }

Celo's transactions differ from Ethereum transactions by including 3 new fields:

  • fee_currency: The currency fees are paid in (None for CELO, otherwise it's an Address)
  • gateway_fee_recipient: The address of the fee recipient (None for no gateway fee paid)
  • gateway_fee: Gateway fee amount (None for no gateway fee paid)

The feature flag enables these additional fields in the transaction request builders and in the transactions which are fetched over JSON-RPC.

Features

  • Ethereum JSON-RPC Client
  • Interacting and deploying smart contracts
  • Type safe smart contract bindings code generation
  • Querying past events
  • Event monitoring as Streams
  • ENS as a first class citizen
  • Celo support
  • Websockets / eth_subscribe
  • Hardware Wallet Support
  • Parity APIs (tracing, parity_blockWithReceipts)
  • Geth TxPool API
  • WASM Bindings
  • FFI Bindings
  • CLI for common operations

Related Projects

This library would not have been possibly without the great work done in:

A lot of the code was inspired and adapted from them, to a unified and opinionated interface, built with async/await and std futures from the ground up.
