Sample Transaction for symbol-sdk v3

nem.js

const { CryptoTypes } = require('symbol-sdk');
const { NemFacade } = require('symbol-sdk').facade;

// Signer Private Key
const privateKey = new CryptoTypes.PrivateKey("PRIVATE_KEY");
const keyPair = new NemFacade.KeyPair(privateKey);

// Create V1 transaction
const transferTransaction = facade.transactionFactory.create({
    type: 'transfer_transaction_v1',
    signerPublicKey: keyPair.publicKey.toString(),
    fee: BigInt(100000), // 0.1 xem
    timestamp, // Get timestamp from network
    deadline: timestamp + 3600, // 1 hour deadline = 60 * 60
    recipientAddress: address,
    amount: BigInt(1000000), // 1 xem
    messageEnvelopeSize: message.length + 4 + 4, // 4 bytes for messageType and 4 bytes for messageEnvelopeSize
    message: {
        messageType: 'plain',
        message: 'hello world'
    }
});

// Sign Transaction
const signature = facade.signTransaction(keyPair, transferTransaction);

const jsonPayload = facade.transactionFactory.constructor.attachSignature(transferTransaction, signature);

// Convert string to json payload
const payload = JSON.parse(jsonPayload);

// Announce payload in POST method
