Make a simple transfer

This sample shows how to create a transaction to make a transfer from one account to another.

// Import the API, Keyring and some utility functions
const { ApiPromise } = require('@polkadot/api');
const { Keyring } = require('@polkadot/keyring');

const BOB = '5FHneW46xGXgs5mUiveU4sbTyGBzmstUspZC92UhjJM694ty';

async function main () {
// Instantiate the API
const api = await ApiPromise.create();

// Construct the keyring after the API (crypto has an async init)
const keyring = new Keyring({ type: 'sr25519' });

// Add Alice to our keyring with a hard-derivation path (empty phrase, so uses dev)
const alice = keyring.addFromUri('//Alice');

// Create a extrinsic, transferring 12345 units to Bob
const transfer = api.tx.balances.transferAllowDeath(BOB, 12345);

// Sign and send the transaction using our account
const hash = await transfer.signAndSend(alice);

console.log('Transfer sent with hash', hash.toHex());

main().catch(console.error).finally(() => process.exit());
