Public Account Key

AccountKeyPublic is used for accounts having one public key. If an account has an AccountKeyPublic object, the transaction validation process is done like below:

Import the @kaiachain/web3js-ext packages to add kaia features on web3

Define sender's address and private keys

Define receiver's address

Set up the provider with the specified kairos testnet URL. A provider in web3js is a read-only abstraction to access the blockchain data.

Also, you can change the provider URL from kairos to quicknode

Define a web3 instance using the provider

Create a sender's wallet with the private key and provider

Create a value transfer transaction with type: TxType.ValueTransfer

Sign the transaction with sender's wallet

Send the signed transaction to kaia network and print the receipt

Recover the address from signed transaction using web3.klay.recoverFromTransaction

SignTxWithPubkeyExample.js

const { Web3, TxType, toPeb } = require("@kaiachain/web3js-ext");

// Using senderPriv == senderNewPriv to execute this example repeatedly.

// But you might want to register a different private key.

const senderAddr = "0xfb60ded0ae96fe04eed6450aead860aa9d57128e";

const senderPriv = "0x0e4ca6d38096ad99324de0dde108587e5d7c600165ae4cd6c2462c597458c2b8";

const receiverAddr = "0xc40b6909eb7085590e1c26cb3becc25368e249e9";

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);

async function main() {

let tx = {

type: TxType.ValueTransfer,

to: receiverAddr,

value: toPeb("0.01", "KLAY"),

from: senderAddr,

};

const signResult = await senderAccount.signTransaction(tx);

console.log("signedTx", signResult.transactionHash);

const receipt = await web3.eth.sendSignedTransaction(signResult.rawTransaction);

console.log("receipt", receipt);

const sig = signResult.signature;

const addr2 = await web3.klay.recoverFromTransaction(senderAddr, sig, "latest");

console.log("recoveredAddr rpc", addr2, addr2.toLowerCase() === senderAddr);

}

main().catch(console.error);
