Implementation of Ethereum public addresses for Rust.

This crate provides an Address type for representing Ethereum public addresses. It implements ERC-55 mixed-case checksum Display formatting and parsing with verification using Address::from_str_checksum().

Additionally an address! macro is included for compile-time verified address constants. Under the hood, it is implemented with const fn and does not use procedural macros.

Usage

Just add a dependency to your Cargo.toml:

[dependencies]
ethaddr = "*"

For complete documentation checkout docs.rs.

Implementation of Ethereum public addresses for Rust.

This crate provides an Address type for representing Ethereum public addresses.

Checksums

Addresses are by default formatted with ERC-55 mixed-case checksum encoding. Addresses checksums may optionally be verified when parsing with [Address::from_str_checksum()].

address! Macro

This crate exports an address! macro that can be used for creating compile-time address constants. Under the hood, it is implemented with const fn and does not use procedural macros.

Features

  • default std: Additional integration with Rust standard library types. Notably, this includes std::error::Error implementation on the ParseAddressError type and conversions from Vec<u8>.
  • serde: Serialization traits for the serde crate. Note that the implementation is very much geared towards JSON serialization with serde_json.
  • sha3: Use the Rust Crypto Keccak-256 implementation (provided by the sha3 crate) instead of the built-in one. Note that the address! macro will always use the built-in Keccak-256 implementation for checksum verification, as sha3 does not expose a const fn API.
