derive-eip712: initial implementation of eip712 derive macro (#481)
* derive-eip712: initial implementation of eip712 derive macro

This commit provides an initial implementation for a derive macro
to encode typed data according to EIP-712, https://eips.ethereum.org/EIPS/eip-712

Additionally, this commit introduces a new signer trait method:

    async fn sign_typed_data<T: Eip712 + Send + Sync>(
        &self,
        payload: &T,
    ) -> Result<Signature, Self::Error>;

And implements the new method for each of the signers (wallet, ledger,
aws).

Additionally, these changes include using `WalletError` for the Wallet
signer error type

At the moment, derive does not recurse the primary type to find nested
Eip712 structs. This is something that is noted in the source and
currently responds with an error regarding custom types.

A subsequent PR should be opened once this issue becomes needed. For the
moment, the current implementation should satisfy non-nested, basic struct types.

* rename to ethers-derive-eip712; move to ethers-core

* refactor of derive-eip712 macro; use ParamType and EthAbiToken

* macro updates; add byte array checker for paramtype; use literal constant for domain type hash

* replace std::convert::Infallible with WalletError as Wallet signer error type

* update workspace members and dev dependencies for examples folder

* add example for eip712 and test against contract

* remove extraneous backward slash in '\x19\x01' prefix; example tests pass

* update unreleased change log

* remove print statements

* use parse_macro_input macro; remove dead code; handle nest struct not implemented error

* move eip712 example to solidity-contract tests folder; update cargo workspace dependencies

* allow optional EIP712Domain parameter when encoding eip712 struct and signing typed data

* add documentation for eip712 feature

* Update ethers-signers/src/ledger/mod.rs

Co-authored-by: Sebastian Martinez <me@sebastinez.dev>

* add error enum for Eip712Error; use sign_payload for ledger signer

* add EIP712WithDomain type for providing a wrapper around custom setting of the domain

* make LedgerWallet sign_payload public

* use optional feature gated dependencies for eip712; add default method for encode_eip712

* add default domain_separator method, pre-compute separator hash

* move derive-eip712 deps to dev deps

* remove invalid sign payload parameter, add await on async method

* remove deprecated comment

* debugging 'bad key handle' error for ledger signer

try using 'sign_message'

* await sign digest for aws signer

* remove extra space, fix fmt warning

* fix test, fmt errors

* use gt 0.6.0 pragma compiler version

* enable ABIEncoderV2 for solidity test contract

* chore: make test constructor public

ethers.rs

Complete Ethereum and Celo wallet implementation and utilities in Rust

Github Actions

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

Getting Help

Contributing

Thanks for your help improving the project! We are so happy to have you! We have a contributing guide to help you get involved in the ethers-rs project.

If you make a Pull Request, do not forget to add your changes in the CHANGELOG.

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.
