Value Transfer

TxTypeValueTransfer 用於用戶發送 KAIA。

• 由於 kaia 提供了多種交易類型，使每種交易類型只服務於一個目的，因此 TxTypeValueTransfer 只限於將 KAIA 發送到外部擁有的賬戶（EOA）。

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

定義發送方、付費方地址和私人密鑰

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 "web3.eth.accounts.privateKeyToAccount "創建帶有私鑰的發件人錢包

使用 "web3.eth.accounts.privateKeyToAccount "用私鑰創建付費者錢包

定義事務對象。

設置 `type：為交易設置 "TxType.FeeDelegatedValueTransfer"，以發送有付費方的價值轉移

設置 value: toPeb("0.01") 以定義要轉換的值，使用 toPeb 將 Klay 轉換為 Peb

設置其他參數，如 從、到

使用 signTransaction 在發送方賬戶上籤署交易

使用 "signTransactionAsFeePayer "以付費方賬戶簽署交易

將交易發送到區塊鏈。 它將返回交易收據
