Overview

This guide shows you how to work with imported TON wallets for common operations. Once you’ve imported a private key, you can perform various wallet operations directly.

​
Prerequisites

​
Step 1: Check Wallet Balance

Check the TON balance of your imported wallet using the TON HTTP API: 
const address = 'YourImportedTonWalletAddress';

const response = await fetch(
  `https://toncenter.com/api/v2/getAddressBalance?address=${address}`
);
const data = await response.json();

const balanceNanotons = BigInt(data.result);
const balanceTon = Number(balanceNanotons) / 1_000_000_000;

console.log('Balance:', balanceNanotons.toString(), 'nanotons');
console.log('Balance in TON:', balanceTon);

​
Step 2: Sign Transactions with Imported Wallet

Use your imported wallet to sign TON transactions. Serialize your cell to base64 before passing it to signTransaction(): 
import { beginCell, toNano } from '@ton/ton';

const tonClient = await authenticatedTonClient();

// Build the transfer body and serialize to base64
const transferBody = beginCell()
  .storeUint(0, 32)
  .storeStringTail('Hello!')
  .endCell();
const transactionString = transferBody.toBoc().toString('base64');

// Sign with imported wallet — returns base64 signature
const signature = await tonClient.signTransaction({
  senderAddress: 'YourImportedTonWalletAddress',
  transaction: transactionString,
});

console.log('Signature (base64):', signature);

​
Step 3: Sign Messages with Imported Wallet

Sign messages for authentication or data integrity: 
const message = 'Hello from my imported TON wallet!';
const signature = await tonClient.signMessage({
  message,
  accountAddress: 'YourImportedTonWalletAddress',
});

// Returns base64-encoded Ed25519 signature
console.log('Message signed (base64):', signature);

​
Step 4: Check Jetton Balances

Check Jetton (TON fungible token) balances in your imported wallet: 
// Get all Jetton wallets for the address via TON HTTP API
const response = await fetch(
  `https://toncenter.com/api/v2/getTokenData?address=${jettonWalletAddress}`
);
const data = await response.json();

console.log('Jetton data:', data.result);

​
Complete Example: Sign and Send from Imported Wallet

import { beginCell, toNano } from '@ton/ton';

export const signAndSendFromImportedWallet = async ({
  walletAddress,
  comment,
}: {
  walletAddress: string;
  comment?: string;
}) => {
  const tonClient = await authenticatedTonClient();

  // Build transfer body
  const body = comment
    ? beginCell().storeUint(0, 32).storeStringTail(comment).endCell()
    : beginCell().endCell();

  // Serialize to base64 string
  const transactionString = body.toBoc().toString('base64');

  // Sign — returns base64 Ed25519 signature
  const signature = await tonClient.signTransaction({
    senderAddress: walletAddress,
    transaction: transactionString,
  });

  console.log('Signature (base64):', signature);
  return signature;
};

​
Best Practices

  1. Balance Checking: Verify sufficient balance before sending transactions
  2. Error Handling: Implement proper error handling for all wallet operations
  3. Security: Never expose sensitive information in server-side code
  4. Network Selection: The SDK currently supports TON Mainnet only
