**Complete Ethereum and Celo wallet implementation and utilities in Rust**
![Github Actions](https://github.com/gakonst/ethers-rs/workflows/Tests/badge.svg)
## Documentation
Extensive documentation and examples are available [here](https://docs.rs/ethers).
Alternatively, you may clone the repository and run `cd ethers/ && cargo doc --open`
## Add ethers-rs to your repository
```toml
[dependencies]
ethers = { git = "github.com/gakonst/ethers-rs" }
```
</details>
### Celo Support
[Celo](http://celo.org/) support is turned on via the feature-flag `celo`:
```toml
[dependencies]
ethers = { git = "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.

## Related Projects
This library would not have been possibly without the great work done in:
- [`ethers.js`](https://github.com/ethers-io/ethers.js/)
- [`rust-web3`](https://github.com/tomusdrw/rust-web3/)
- [`ethcontract-rs`](https://github.com/gnosis/ethcontract-rs/)
- [`guac_rs`](https://github.com/althea-net/guac_rs/tree/master/web3/src/jsonrpc)
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.
