Universal Etheruem signature verification with ERC-6492
This crate verifies any Ethereum signature including:
Usage
This crate uses Alloy and requires an RPC provider in order to verify all signature types.
use alloy::primitives::{address, bytes, eip191_hash_message};
use alloy::providers::{network::Ethereum, ReqwestProvider};
use eth_signature_verifier::verify_signature;
#[tokio::main]
async fn main() {
let address = address!("0xc0ffee254729296a45a3885639AC7E10F9d54979");
let message = "coffee";
let signature = bytes!("0x9c22ff5f21f0b81b113e63f7db6da94fedef11b2119b4088b89664fb9a3cb658");
let provider = ReqwestProvider::<Ethereum>::new_http("https://rpc.example.com");
let verification = verify_signature(signature, address, message, provider).await.unwrap();
if verification.is_valid() {
// signature valid
}
}
This crate also allows for the extracting of an address from a signature, as shown below:
use eth_signature_verifier::extract_address;
#[tokio::main]
async fn main() {
let signature = bytes!("0x9c22ff5f21f0b81b113e63f7db6da94fedef11b2119b4088b89664fb9a3cb658")
let address = extract_address(signature).await.unwrap(); // works for EOA, ERC1271, ERC6492
dbg!(address);
}
See test cases in src/lib.rs
for more examples.
