Cancel

TxTypeCancel cancels the execution of the transaction with the same nonce in the transaction pool. 이 트랜잭션 유형은 제출된 트랜잭션이 일정 시간 동안 처리되지 않은 것처럼 보일 때 유용합니다.

Import the ethers and @kaiachain/ethers-ext packages to add kaia features on ethers.js

Define sender address and sender private key

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

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

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

Declare a transaction with the from field as sender address and the type field as TxType.Cancel.

Send the tx to the blockchain. Function sendTransaction internally signs with the private key of the account and then transmits it to the blockchain network.

The wait function returns the tx receipt if it is completed in the blockchain.

TxCancelType.js


const ethers = require("ethers");
const { Wallet, TxType } = require("@kaiachain/ethers-ext/v6");
const senderAddr = "0xa2a8854b1802d8cd5de631e690817c253d6a9153";
const senderPriv = "0x0e4ca6d38096ad99324de0dde108587e5d7c600165ae4cd6c2462c597458c2b8";
const provider = new ethers.JsonRpcProvider("https://public-en-kairos.node.kaia.io");
const wallet = new Wallet(senderPriv, provider);
async function main() {
  const tx = {
    type: TxType.Cancel,
    from: senderAddr,
  };
  const sentTx = await wallet.sendTransaction(tx);
  console.log("sentTx", sentTx.hash);
  const receipt = await sentTx.wait();
  console.log("receipt", receipt);
}
main();
