Struct ethers_signers::Wallet

pub struct Wallet<D: DigestSigner<ProxyDigest<Sha256>, RecoverableSignature>> { /* fields omitted */ }

An Ethereum private-public key pair which can be used for signing messages.

Examples

Signing and Verifying a message

The wallet can be used to produce ECDSA Signature objects, which can be then verified. Note that this uses hash_message under the hood which will prefix the message being hashed with the Ethereum Signed Message domain separator.

use ethers_core::rand::thread_rng;
use ethers_signers::{LocalWallet, Signer};

let wallet = LocalWallet::new(&mut thread_rng());

// Optionally, the wallet's chain id can be set, in order to use EIP-155
// replay protection with different chains
let wallet = wallet.with_chain_id(1337u64);

// The wallet can be used to sign messages
let message = b"hello";
let signature = wallet.sign_message(message).await?;
assert_eq!(signature.recover(&message[..]).unwrap(), wallet.address());
