Make a Transaction - Base Documentation

Base uses the same transaction model as Ethereum, so any EVM library works. Here’s a minimal send using viem.

Send a Transaction

send.ts

import { createWalletClient, http, parseEther } from 'viem';
import { privateKeyToAccount } from 'viem/accounts';
import { base } from 'viem/chains';

const account = privateKeyToAccount('0xYourPrivateKey');

const client = createWalletClient({
  account,
  chain: base,
  transport: http('https://mainnet.base.org'),
});

const hash = await client.sendTransaction({
  to: '0xRecipientAddress',
  value: parseEther('0.001'),
});

console.log(`Sent, view at https://basescan.org/tx/${hash}`);

Never hardcode or expose a private key. '0xYourPrivateKey' is a placeholder. Load the key from an environment variable or a secrets manager, keep it server-side, and never commit it to source control.

Transactions confirm in under a second on Base thanks to Flashblocks, and typically cost a fraction of a cent in gas.
