Solidity và ethers.js Tính toán các địa chỉ khác nhau từ cùng một chữ ký

Kịch bản này:

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

async function recoverSigner(address, nonce, deadline, v, r, s) {
    const domain = {
        name: "RandomReachDebug5Local",
        version: "1",
        chainId: 31337,
        verifyingContract: "0x8464135c8F25Da09e49BC8782676a84730C318bC",
    };
    const types = {
        RequestRandomNFT: [
            { name: 'minter', type: 'address' },
            { name: 'nonce', type: 'uint256' },
            { name: 'deadline', type: 'uint256' },
        ],
    };
    const value = {
        minter: address,
        nonce: nonce,
        deadline: deadline,
    };

    // Get the digest of the message
    const digest = ethers.utils._TypedDataEncoder.hash(domain, types, value);
    
    const sig = {
        r: r,
        s: s,
        v: v,
    };

    if (sig.v < 27) {
        sig.v += 27;
    }

    const signer = ethers.utils.recoverAddress(digest, sig);
    
    return signer;
}

const address = "0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266";
const nonce = "0";
const deadline = "1685162164";
const v = "28";
const r = "0xe0e4cc2f8b6bac3784f9feb3db4382291631d5f317d08a0b82305e5eb5ffc60a";
const s = "0x0416d521d12e26b8fc1f4bd566d5d67c5dffebe9564fe90db4f12c0a69b63d5e";

async function run() {
    try {
        const signer = await recoverSigner(address, nonce, deadline, v, r, s);
        console.log(`The signer is: ${signer}`);
    } catch (error) {
        console.error(`Error in recovering signer: ${error}`);
    }
}

run();

Produces this output: The signer is: 0x1AB26702A8068a247BD33a9555dfEf791d2BD68D

Deployed with this script in hardhat:

import { ethers } from "hardhat";

const hre = require("hardhat");
const dotenv = require("dotenv");
dotenv.config();

async function main() {
  const GetAddressFromSig = await hre.ethers.getContractFactory("GetAddressFromSig");
  const gasPrice = await GetAddressFromSig.signer.getGasPrice();
  console.log(`Current gas price: ${gasPrice}`);
  const estimatedGas = await GetAddressFromSig.signer.estimateGas(
    GetAddressFromSig.getDeployTransaction("RANDOM NFT 5", "RNFT5"),
  );
  console.log(`Estimated gas: ${estimatedGas}`);
  const deploymentPrice = gasPrice.mul(estimatedGas);
  const deployerBalance = await GetAddressFromSig.signer.getBalance();
  console.log(`Deployer balance:  ${ethers.utils.formatEther(deployerBalance)}`);
  console.log(`Deployment price:  ${ethers.utils.formatEther(deploymentPrice)}`);
  const getAddressFromSig = await GetAddressFromSig.deploy("RANDOM NFT 5", "RNFT5");

  await getAddressFromSig.deployed();

  console.log("GetAddressFromSig deployed to:", getAddressFromSig.address);
}

main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

And ran with these commands in the hardhat console:

const Token = await ethers.getContractFactory("GetAddressFromSig");
const token = await Token.attach("0x8464135c8F25Da09e49BC8782676a84730C318bC");
const request = { minter: "0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266", nonce: ethers.BigNumber.from("0"), deadline: ethers.BigNumber.from("1685162164") };
const v = 28
const r = "0xe0e4cc2f8b6bac3784f9feb3db4382291631d5f317d08a0b82305e5eb5ffc60a";
const s = "0x0416d521d12e26b8fc1f4bd566d5d67c5dffebe9564fe90db4f12c0a69b63d5e";
const signer = await token.recoverSigner(request, v, r, s);
console.log(`The signer is: ${signer}`);

Cung cấp cho đầu ra này: người ký là: 0xEB7265F6625EAE66403A637C073E63CCF33B8CDC

Vậy tại sao javascript tính 0x1AB26702A8068A247BD33A9555DFEF791D2BD68D, trong khi trình biên dịch solidity của hardhat tính 0xEB7265F6625EAE66403A637C073E63CCF33B8CDC?
