導入 web3 和 @kaiachain/web3js-ext 軟件包，在 web3 上添加 kaia 功能

定義發送方、接收方地址和發送方私人密鑰

使用指定的 kairos 測試網 URL 設置提供程序。 web3js 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

定義交易數據，包括從（發送方地址）、到（接收方地址）、值（轉賬金額，使用 toPeb 在 Klay 中設置值，然後進行轉換）

使用 privateKeyToAccount 方法，可以用發送者的私鑰創建賬戶實例。

signTransaction 方法與發件人賬戶簽署交易。

sendSignedTransaction 方法將已簽名的交易發送到區塊鏈中。

getTransactionReceipt 方法返回交易收據。

最後，得到結果。
