AccountUpdateWithLegacy.js


const { Web3, TxType, AccountKeyType, getPublicKeyFromPrivate } = require("@kaiachain/web3js-ext");
// Using senderPriv == senderNewPriv to execute this example repeatedly.
// But you might want to register a different private key.
const senderAddr = "0xecbf243ac167a3b5097fef758e07881582a89027";
const senderPriv = "0xc696ccd259792f2ffb87e0012e4a37ae3526a3224686225af679e3aaa2aeab0d";
const provider = new Web3.providers.HttpProvider("https://public-en-kairos.node.kaia.io");
const web3 = new Web3(provider);
const senderAccount = web3.eth.accounts.privateKeyToAccount(senderPriv);
