Legacy Account Key

AccountKeyLegacy

導入 ethers 和 @kaiachain/ethers-ext 軟件包，在 ethers.js 上添加 kaia 功能

定義發件人地址和私人密鑰

使用指定的 kairos 測試網 URL 設置提供程序。以太坊中的提供者是訪問區塊鏈數據的只讀抽象。

此外，您還可以將提供商 URL 從 kairos 更改為 quicknode

用私鑰和提供者創建發件人錢包

在 key 字段中聲明一個交易，其值為 "AccountKeyType.Legacy`"。

向區塊鏈發送 tx。函數 "sendTransaction "使用賬戶的私鑰進行內部簽名，然後將其傳輸到區塊鏈網絡。

如果已在區塊鏈中完成發送，wait函數將返回發送回執。

AccountUpdateWithLegacy.js


const { ethers } = require("ethers");
const { Wallet, TxType, AccountKeyType} = require("@kaiachain/ethers-ext");
// Using legacy AccountKey to execute this example repeatedly.
// But you might want to register a different Accountkey.
const senderAddr = "0xecbf243ac167a3b5097fef758e07881582a89027";
const senderPriv = "0xc696ccd259792f2ffb87e0012e4a37ae3526a3224686225af679e3aaa2aeab0d";
const provider = new ethers.providers.JsonRpcProvider("https://public-en-kairos.node.kaia.io");
const wallet = new Wallet(senderPriv, provider);
async function main() {
  const tx = {
    type: TxType.AccountUpdate,
    from: senderAddr,
    key: {
      type: AccountKeyType.Legacy,
    }
  };
  const sentTx = await wallet.sendTransaction(tx);
  console.log("sentTx", sentTx.hash);
  const receipt = await sentTx.wait();
  console.log("receipt", receipt);
}
