Send Transactions Using SDKs

Installation

npm install js-conflux-sdk

Send transaction using SDK

• Import js-conflux-sdk and set a Conflux provider. For the Conflux test-net, there is a node provided at https://test.confluxrpc.com. It can also be changed to any other Conflux node, even your own.

const { Conflux, Drip } = require('js-conflux-sdk');

const conflux = new Conflux({
  url: 'https://test.confluxrpc.com',
  logger: console,
  networkId: 1,
});

• Paste your private key into the program

const PRIVATE_KEY = 'Your Private Key';
// const PRIVATE_KEY = '0x5f15f9e52fc5ec6f77115a9f306c120a7e80d83115212d33a843bb6b7989c261';
const account = conflux.wallet.addPrivateKey(PRIVATE_KEY); // create account instance
const receiver = 'cfxtest:aarc9abycue0hhzgyrr53m6cxedgccrmmy8m50bu1p'

• Compose your transaction:

let txParams = {
  from: account, // from account instance and will by sign by account.privateKey
  // nonce
  // gasPrice
  // gas
  to: receiver, // accept address string or account instance
  value: Drip.fromCFX(0.125), // use the conversion utility function
  // storageLimit
  // epochHeight
  // data
};

The detailed explanation of each field can be found here

• Send the composed transaction via cfx.sendTransaction and get the returned transaction hash. Then you can view the transaction details by using tx.mined() or tx.executed(), which APIs will return the transaction data or transaction receipt when transaction is mined or executed. Noting these 2 APIs are a simple wrapping layer for cfx.getTransactionByHash and cfx.getTransactionReceipt. You can also search the hash at Conflux Scan.

async function main() {
  const txHash = await conflux.cfx.sendTransaction(txParams);
  console.log(txHash);
  const txData = await txHash.mined()
  console.log(txData)
  const txReceipt = await txHash.executed()
  console.log(txReceipt)
}

main().catch(e => console.error(e));
