[ethers.js] HD wallet으로 주소 파생

다솜돌이 Leave a comment

12개의 seed wallet이 있는 경우, 다음과 같이 파생 주소를 확인할 수 있다.

$ npm install ethers@^5.0.0

const { ethers } = require('ethers');

// 12개의 시드 단어를 여기에 입력하세요
const mnemonic = "Your seed 12 words here";

// HD Node 생성
const hdNode = ethers.utils.HDNode.fromMnemonic(mnemonic);

// 파생 경로 설정
const derivationPath = "m/44'/60'/0'/0/"; // "m/44'/905956'/0'/0/" 와 같이 사용도 가능

// 파생 주소 생성 및 출력 함수
function generateAddresses(count) {
    const addresses = [];
    for (let i = 0; i < count; i++) {
        const walletNode = hdNode.derivePath(derivationPath + i);
        console.log(i, walletNode.address);
        addresses.push({
            index: i,
            address: walletNode.address,
        });
    }
    return addresses;
}

// 원하는 주소 개수를 설정하세요
const numAddresses = 85535;
const addresses = generateAddresses(numAddresses);

        return {
            gasPrice: ethers.BigNumber.from(0),

        };
      };
      console.log(`LedgerSinger: m/44'/60'/${accountNumber}'/0/0:`, await _master.getAddress());
      _master.getBalance = async function() {
        return await this.provider.getBalance(this.getAddress());
      };

      return _master;
    }

    const accounts = await ethers.getSigners();
    return accounts[accountNumber];
  });

사용할 때는 hre를 이용해서 다음과 같이 하면 된다.

import { task } from "hardhat/config";
import './subtasks/getLedgerSigner';

task("ledgerBalance", "Prints an account's balance")
  .addOptionalPositionalParam("accountNumber", "The account number of the ledger", "0")
  .setAction(async (taskArgs) => {
    const signer = await hre.run("getLedgerSigner", { accountNumber: taskArgs.accountNumber });
    console.log("Signer Address:", await signer.getAddress());
    const balance = await signer.getBalance();

    console.log(ethers.utils.formatEther(balance), "ETH");
  });

ethers.js v5 기준 hardhat 태스크

import { LedgerSigner } from "@anders-t/ethers-ledger";
import { task } from "hardhat/config";

task("checkHW", "Check HW Wallet")
  .addOptionalPositionalParam("accountNumber", "Index of the address of the HW wallet")
  .setAction(async (taskArgs) => {
  const accountNumber = taskArgs.accountNumber;
    const _master = new LedgerSigner(ethers.provider, `m/44'/60'/${accountNumber}'/0/0`);
  _master.getFeeData = async () => {
    return {
      gasPrice: ethers.BigNumber.from(0),
      lastBaseFeePerGas: ethers.BigNumber.from(0),
      maxFeePerGas: ethers.utils.parseUnits("800", "gwei"),
      maxPriorityFeePerGas: ethers.utils.parseUnits("800", "gwei"),
    };
  };
  const master = _master;

  console.log(`HW Ledger: [${accountNumber}]:${await master.getAddress()}: ${ethers.utils.formatEther(await master.getBalance())} ETH`);
});

사용은 hh checkHW 0 와 같이 한다.
