更新賬戶

導入 web3 和 @kaiachain/web3js-ext 軟件包，在 web3 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。 web3 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

使用提供程序創建KlaytnWeb3實例

用私鑰和提供者創建發件人錢包

用新私鑰計算公鑰

用計算出的 ** 公鑰** 在 key 字段中聲明一個事務。

用發送方的私人密鑰簽署交易

向區塊鏈發送已簽名的 tx。它將返回交易的收據
