Universal Rust Etheruem signature verification with ERC-6492

This crate verifies any Ethereum signature including:

• EOAs
• Smart contract wallets with ERC-1271
• Predeploy contract wallets with ERC-6492

Install

cargo add erc6492 --git https://github.com/reown-com/erc6492

or

erc6492 = { git = "https://github.com/reown-com/erc6492.git", version = "0.1.0" }

Usage

This crate uses Alloy and requires an RPC provider in order to verify all signature types.

let address = address!("AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA");
let message = eip191_hash_message("Hello, world!");
let signature = bytes!("aaaa");
let provider = ReqwestProvider::<Ethereum>::new_http("https://rpc.example.com".parse().unwrap());

let verification = verify_signature(signature, address, message, provider).await.unwrap();
if verification.is_valid() {
    // signature valid
}

See doctest on verify_signature() and test cases in src/lib.rs for more examples.
