To be able to use your account on TON, you need to have an initialized wallet. Wallet initialization means deploying a TON wallet contract for your account.

While this is a great feature of the TON blockchain, you might find it cumbersome dealing with wallet deployments during your development stage.

So here’s a couple of scripts in JavaScript using tonweb that can help you:

  • GenerateAndInitialize.js — a script that generates a key pair for an account and then keeps running until you top it up with TON; once the account has enough TON, the script deploys a wallet contract.
  • CheckAndDepoy.js — a script that checks whether an account is initialized; if it’s not initialized, the script deploys a wallet contract.

​
Prerequisites

Make sure tonweb is installed.

​
GenerateAndInitialize

This script does the following:

  • Generates a key pair and saves it to wallet_keys.json
  • Keeps running and checking the balance of the generated account until it’s topped up
  • Once the account is topped up, the script deploys a v4R2 wallet contract
const TonWeb = require('tonweb');
const fs = require('fs');

const httpProvider = new TonWeb.HttpProvider('CHAINSTACK_NODE_WITH_jsonRPC');
const tonweb = new TonWeb(httpProvider);

async function generateAndInitializeWallet() {
    // Generate a new key pair
    const keyPair = TonWeb.utils.nacl.sign.keyPair();

    // Create a v4R2 wallet instance
    const WalletClass = tonweb.wallet.all['v4R2'];
    const wallet = new WalletClass(tonweb.provider, {
        publicKey: keyPair.publicKey,
        wc: 0
    });

    // Get the wallet address
    const walletAddress = await wallet.getAddress();
    const addressString = walletAddress.toString(true, true, true);

    console.log('Generated wallet address:', addressString);
    console.log('Please send some TON to this address to initialize the wallet.');

    // Save the key pair to a file
    const keyPairData = {
        publicKey: TonWeb.utils.bytesToHex(keyPair.publicKey),
        secretKey: TonWeb.utils.bytesToHex(keyPair.secretKey)
    };
    fs.writeFileSync('wallet_keys.json', JSON.stringify(keyPairData, null, 2));
    console.log('Key pair saved to wallet_keys.json');

    // Wait for the wallet to be topped up
    await waitForBalance(walletAddress);

    // Initialize the wallet
    console.log('Initializing wallet...');
    const deployResult = await wallet.deploy(keyPair.secretKey).send();
    console.log('Deployment transaction sent:', deployResult);

    console.log('Waiting for deployment to complete...');
    await new Promise(resolve => setTimeout(resolve, 10000)); // Wait for 10 seconds

    const seqno = await wallet.methods.seqno().call();
    if (seqno !== null) {
        console.log('Wallet successfully initialized!');
    } else {
        console.log('Wallet initialization might have failed. Please check the address on a block explorer.');
    }
}

async function waitForBalance(address) {
    while (true) {
        const balance = await tonweb.getBalance(address);
        if (balance && balance !== '0') {
            console.log('Balance detected:', TonWeb.utils.fromNano(balance), 'TON');
            break;
        }
        await new Promise(resolve => setTimeout(resolve, 5000)); // Check every 5 seconds
    }
}

generateAndInitializeWallet().catch(console.error);

Make sure you put your Chainstack TON node endpoint with a /jsonRPC at the end instead of CHAINSTACK_NODE_WITH_jsonRPC.

​
CheckAndDepoy

This script does the following:

  • Converts the private key to an account address
  • Checks the account if it’s initialized or not
  • Checks the balance
  • If the account is not initialized and has enough TON coins for wallet contract deployment, proceeds with the deployment
const TonWeb = require('tonweb');

const privateKey = 'PRIVATE_KEY';

const httpProvider = new TonWeb.HttpProvider('CHAINSTACK_NODE_WITH_jsonRPC');
const tonweb = new TonWeb(httpProvider);

async function deployWallet() {
    try {
        const keyPair = TonWeb.utils.nacl.sign.keyPair.fromSecretKey(TonWeb.utils.hexToBytes(privateKey));
        const WalletClass = tonweb.wallet.all['v4R2'];
        const wallet = new WalletClass(tonweb.provider, {
            publicKey: keyPair.publicKey,
            wc: 0
        });

        const walletAddress = await wallet.getAddress();
        console.log('Wallet address:', walletAddress.toString(true, true, true));

        const balance = await tonweb.provider.getBalance(walletAddress.toString());
        console.log('Wallet balance:', balance);

        if (balance === '0') {
            console.error('Wallet has no balance. Please add funds before deploying.');
            return;
        }

        const seqno = await wallet.methods.seqno().call();
        console.log('Seqno:', seqno);

        if (seqno === null) {
            console.log('Wallet not deployed. Deploying...');
            const deployResult = await wallet.deploy(keyPair.secretKey).send();
            console.log('Deploy result:', deployResult);
        } else {
            console.log('Wallet already deployed. Seqno:', seqno);
        }
    } catch (error) {
        console.error('Unexpected error:', error.message);
    }
}

deployWallet();

Make sure you put your Chainstack TON node endpoint with a /jsonRPC at the end instead of CHAINSTACK_NODE_WITH_jsonRPC; and put your private key inPRIVATE_KEY.
