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.

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 = "*"
