Public Account Key

AccountKeyPublic 用於有一個公鑰的賬戶。如果賬戶有一個 AccountKeyPublic 對象，交易驗證過程如下：

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

聲明一個事務，其類型為 賬戶密鑰類型.公鑰，密鑰字段為新計算的公鑰。

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。
