ethereum-tx-sign

This is a Rust library that allows you to create and sign Ethereum transactions. It can work completely offline and does not require external software such as Web3. Legacy and access list transactions are supported (EIP-155 and EIP-2930 respectively).

Build Status

Usage

Native Rust types are used for transaction fields:

use ethereum_tx_sign::LegacyTransaction;

let new_transaction = LegacyTransaction {
    chain: 1,
    nonce: 0,
    to: Some([0; 20]),
    value: 1675538,
    gas_price: 250,
    gas: 21000,
    data: vec![/* contract code or other data */],
}

Signing a transaction is performed in two steps. First you get the ECDSA using your private key. Then sign the transaction using it.

let ecdsa = new_transaction.ecdsa(&private_key_32_bytes);
let transaction_bytes = new_transaction.sign(&ecdsa);

transaction_bytes is now a Vec<u8> containing the serialized transaction ready to be sent.

See the Rust documentation on docs.rs for more information and examples.
