ethers.rs
Complete Ethereum and Celo wallet implementation and utilities in Rust
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:
solc. We also recommend using solc-select for more flexibility.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.

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.
