價值轉移

TxTypeValueTransfer 在用戶希望發送 KAIA 時使用。

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

定義發件人地址、發件人私鑰和收件人地址

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private key和** provider**創建發件人錢包

聲明包含 ** type, from, to, value** 等字段的事務。

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。

const ethers = require("ethers");
const { Wallet, TxType, parseKlay } = require("@kaiachain/ethers-ext");
const recieverAddr = "0xc40b6909eb7085590e1c26cb3becc25368e249e9";

const provider = new ethers.providers.JsonRpcProvider("https://public-en-kairos.node.kaia.io");
const wallet = new Wallet(senderPriv, provider);
async function main() {
  const tx = {
    type: TxType.ValueTransfer,
    from: senderAddr,

  };
  const sentTx = await wallet.sendTransaction(tx);
  console.log("sentTx", sentTx);
  const receipt = await sentTx.wait();
  console.log("receipt", receipt);
}
