Usage

const hardwareWalletModule = require('@nxqbao/eth-signer-trezor');
const providers = require('ethers').providers;

const TrezorSigner = hardwareWalletModule.TrezorSigner;
const provider = new providers.JsonRpcProvider(providerUrl);
const derivationPath = `m/44'/60'/0'/0`;  // This follows BIP-44 wallet, without <index> in derivation path

/**

 *
 * const index = 0;
 * const address = undefined;
 **/
const index = undefined;
const address = "0xcB6a85e9Ff428d0cD7c6F3D7A03Aa5F6DF771525";
const sessionName = 'trezor user'

const ethersSigner = new TrezorSigner(
    provider,
    derivationPath,
    index,
    address,
    sessionName
);

Implementation

The TrezorSigner class in trezor-signer.ts satisfies following:

• extends ethers.signer
• loads and interacts with Trezor Connect
• fetches public key by derivation path from Trezor and derives available addresses in the device
