linera-alloy-signer
Ethereum signer abstraction.
You can implement the Signer
trait to extend functionality to other signers
such as Hardware Security Modules, KMS etc. See its documentation for more.
Signer implementation in Alloy:
Examples
Sign an Ethereum prefixed message (EIP-712):
use linera_alloy_signer::{Signer, SignerSync};
// Instantiate a signer.
let signer = linera_alloy_signer_wallet::LocalWallet::random();
// Sign a message.
let message = "Some data";
let signature = signer.sign_message_sync(message.as_bytes())?;
// Recover the signer from the message.
let recovered = signature.recover_address_from_msg(message)?;
assert_eq!(recovered, signer.address());
# Ok::<_, Box<dyn std::error::Error>>(())
Sign a transaction:
use linera_alloy_consensus::TxLegacy;
use linera_alloy_primitives::{U256, address, bytes};
use linera_alloy_signer::{Signer, SignerSync};
use linera_alloy_network::{TxSignerSync};
// Instantiate a signer.
let signer = "dcf2cbdd171a21c480aa7f53d77f31bb102282b3ff099c78e3118b37348c72f7"
.parse::<linera_alloy_signer_wallet::LocalWallet>()?;
// Create a transaction.
let mut tx = TxLegacy {
to: address!("d8dA6BF26964aF9D7eEd9e03E53415D37aA96045").into(),
value: U256::from(1_000_000_000),
gas_limit: 2_000_000,
nonce: 0,
gas_price: 21_000_000_000,
input: bytes!(),
chain_id: Some(1),
};
// Sign it.
let signature = signer.sign_transaction_sync(&mut tx)?;
# Ok::<_, Box<dyn std::error::Error>>(())
