Access TransitSwap for a trusted data:0x9e30f587c47c65791cd58fe4d6f2e889a13d6d8f22623c65960fb625f95e13c2

驗證簽名：

可以驗證返回的數據簽名是否為TransitSwap返回，還可以檢查時間是否在有效範圍內（例如 30 秒內），防止數據被惡意修改。

使用的簽名工具：https://www.npmjs.com/package/@metamask/eth-sig-util

生成hash的工具：https://www.npmjs.com/package/ethers

const sigUtils = require("@metamask/eth-sig-util")
const ethers = require("ethers")
const routers = [..data.contracts.Router]
const approves = [..data.contracts.Approve]
//如果是波場地址，請先轉為hex格式
const hash = ethers.utils.solidityKeccak256(["address[]", "address[]", "uint256"], [routers, approves, timestamp])
const data = "Access TransitSwap for a trusted data:" + hash
const signer = sigUtils.recoverPersonalSignature({data:data,signature:signature})
if (signer == "0x6eef5ad82cf83f9e60d2e96ee2029dc17c7b6612") {
    //code
