Account Update

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

定義要更改的發件人地址、發件人私人密鑰和新私人密鑰

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

用新私鑰計算公鑰

在 key 字段中使用計算出的 ** 公鑰** 聲明一個事務

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。

TxTypeAccountUpdate.js


const ethers = require("ethers");
const { Wallet, TxType, AccountKeyType } = require("@kaiachain/ethers-ext");
// Using senderPriv == senderNewPriv to execute this example repeatedly.
// But you might want to register a different private key.
const senderAddr = "0xe15cd70a41dfb05e7214004d7d054801b2a2f06b";
const senderPriv = "0x0e4ca6d38096ad99324de0dde108587e5d7c600165ae4cd6c2462c597458c2b8";

const provider = new ethers.providers.JsonRpcProvider("https://public-en-kairos.node.kaia.io");
const wallet = new Wallet(senderAddr, senderPriv, provider); // decoupled account
