Usage

To use this library you need HTTP API endpoint, you can use one of the public endpoints:

Mainnet: https://toncenter.com/api/v2/jsonRPC
Testnet: https://testnet.toncenter.com/api/v2/jsonRPC

import { TonClient, WalletContractV4, internal } from "@ton/ton";
import { mnemonicNew, mnemonicToPrivateKey } from "@ton/crypto";

// Create Client
const client = new TonClient({
  endpoint: 'https://toncenter.com/api/v2/jsonRPC',
});

// Generate new key
let mnemonics = await mnemonicNew();
let keyPair = await mnemonicToPrivateKey(mnemonics);

// Create wallet contract
let workchain = 0; // Usually you need a workchain 0
let wallet = WalletContractV4.create({ workchain, publicKey: keyPair.publicKey });
let contract = client.open(wallet);

// Get balance
let balance: bigint = await contract.getBalance();

// Create a transfer
let seqno: number = await contract.getSeqno();
let transfer = await contract.createTransfer({
  seqno,
  secretKey: keyPair.secretKey,
  messages: [internal({
    value: '1.5',
    to: 'EQCD39VS5jcptHL8vMjEXrzGaRcCVYto7HUn4bpAOg8xqB2N',
    body: 'Hello world',
  })]
});
