**Complete Ethereum and Celo wallet implementation and utilities in Rust**
|
|
|
|
|
|
|
|
## 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 = "https://github.com/gakonst/ethers-rs" }
|
|
```
|
|
|
|
</details>
|
|
|
|
## Running the tests
|
|
|
|
Tests require the following installed:
|
|
1. [`solc`](https://solidity.readthedocs.io/en/latest/installing-solidity.html)
|
|
2. [`ganache-cli`](https://github.com/trufflesuite/ganache-cli#installation)
|
|
|
|
In addition, it is recommended that you set the `ETHERSCAN_API_KEY` environment variable
|
|
for [the abigen via Etherscan](https://github.com/gakonst/ethers-rs/blob/master/ethers/tests/major_contracts.rs) tests.
|
|
You can get one [here](https://etherscan.io/apis).
|
|
|
|
### Celo Support
|
|
|
|
[Celo](http://celo.org/) support is turned on via the feature-flag `celo`:
|
|
|
|
```toml
|
|
[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:
|
|
- [`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.
