alloy
A Rust Ethereum library by the Foundry team — successor to ethers-rs, providing async Ethereum types, RPC clients, contract bindings, and signing infrastructure.
alloy, released in 2024, is the Paradigm/Foundry team's Rust Ethereum library. It is the successor to ethers-rs: same primary maintainers, deeper integration with reth and Foundry's tooling, and a redesigned async-first API.
The library covers Ethereum primitives (Address, U256, bytes,
RLP), JSON-RPC clients, EIP-712 signing, ABI encoding/decoding,
and contract bindings via the sol! procedural macro. Most
new Rust Ethereum projects use alloy directly.
