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

定義發件人的地址和私人密鑰

定義接收方的地址

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

用私鑰和提供者創建發件人錢包

使用 type.TxType.ValueTransfer 創建一個價值轉移事務，以便以後使用 klay_recoverFromTransaction 恢復：TxType.ValueTransfer"，以便以後使用 "klay_recoverFromTransaction "恢復它

用發件人的錢包簽署交易，"populateTransaction "方法為交易對象添加更多參數，如gas、nonce...

將簽署的交易發送至 kaia 網絡

等待交易完成並打印收據

使用 klay_recoverFromMessage 從已簽署的事務中恢復地址

SignTxWithPubkeyExample.js

const { ethers } = require("ethers");

const { Wallet, TxType, parseKlay } = require("@kaiachain/ethers-ext/v6");

const senderAddr = "0xe15cd70a41dfb05e7214004d7d054801b2a2f06b";

const recieverAddr = "0xc40b6909eb7085590e1c26cb3becc25368e249e9";

const provider = new ethers.JsonRpcProvider("https://public-en-kairos.node.kaia.io");

console.log("receipt", receipt);

const addr = await provider.send("klay_recoverFromTransaction", [rawTx, "latest"]);

console.log("recoveredAddr rpc", addr, addr.toLowerCase() === senderAddr.toLowerCase());

}

main().catch(console.error);
