合金签名者

以太坊签名抽象。

您可以实现 Signer 特性，以扩展功能到其他签名者，如硬件安全模块、KMS 等。更多信息请参阅 其文档。

Alloy 中的签名者实现

• K256 私钥
• YubiHSM2
• Ledger
• Trezor
• AWS KMS
• GCP KMS

示例

签名以太坊前缀消息（《EIP-712》）

use alloy_signer::{Signer, SignerSync};
use alloy_signer_local::PrivateKeySigner;

// Instantiate a signer.
let signer = PrivateKeySigner::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>>(())

签名交易

use alloy_consensus::TxLegacy;
use alloy_primitives::{U256, address, bytes};
use alloy_signer::{Signer, SignerSync};
use alloy_signer_local::PrivateKeySigner;
use alloy_network::{TxSignerSync};

// Instantiate a signer.
let signer = "dcf2cbdd171a21c480aa7f53d77f31bb102282b3ff099c78e3118b37348c72f7"
    .parse::<PrivateKeySigner>()?;

// 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>>(())
