@tetherto/wdk-wallet-ton

Note: This package is currently in beta. Please test thoroughly in development environments before using in production.

A simple and secure package to manage BIP-44 wallets for the TON blockchain. This package provides a clean API for creating, managing, and interacting with TON wallets using BIP-39 seed phrases and TON-specific derivation paths.

🔍 About WDK

This module is part of the WDK (Wallet Development Kit) project, which empowers developers to build secure, non-custodial wallets with unified blockchain access, stateless architecture, and complete user control.

• Multi-Account Management: Create and manage multiple accounts from a single seed phrase
• Transaction Management: Send transactions and get fee estimates
• Jetton Support: Query native TON and Jetton token balances using smart contract interactions

⬇️ Installation

To install the @tetherto/wdk-wallet-ton package, follow these instructions:

You can install it using npm:

npm install @tetherto/wdk-wallet-ton

🚀 Quick Start

Importing from @tetherto/wdk-wallet-ton

Creating a New Wallet

import WalletManagerTon, { WalletAccountTon, WalletAccountReadOnlyTon } from '@tetherto/wdk-wallet-ton'

// Use a BIP-39 seed phrase (replace with your own secure phrase)
const seedPhrase = 'test only example nut use this real life secret phrase must random'

// Create wallet manager with TON client config
const wallet = new WalletManagerTon(seedPhrase, {
  tonClient: {
    url: 'https://toncenter.com/api/v3',
    secretKey: 'your-api-key' // Optional
  },
  transferMaxFee: 1000000000 // Optional: Maximum fee in nanotons
})

// Get a full access account
const account = await wallet.getAccount(0)

// Convert to a read-only account
const readOnlyAccount = await account.toReadOnlyAccount()

Managing Multiple Accounts

import WalletManagerTon from '@tetherto/wdk-wallet-ton'

// Assume wallet is already created
// Get the first account (index 0)
const account = await wallet.getAccount(0)
const address = await account.getAddress()
console.log('Account 0 address:', address)

// Get the second account (index 1)
const account1 = await wallet.getAccount(1)
const address1 = await account1.getAddress()
console.log('Account 1 address:', address1)

// Get account by custom derivation path
// Full path will be m/44'/607'/0'/0/5
const customAccount = await wallet.getAccountByPath("0'/0/5")
const customAddress = await customAccount.getAddress()
console.log('Custom account address:', customAddress)

// Note: All addresses are TON addresses (EQ... or UQ...)
// All accounts inherit the provider configuration from the wallet manager

Checking Balances

Owned Account

For accounts where you have the seed phrase and full access:

import WalletManagerTon from '@tetherto/wdk-wallet-ton'

// Assume wallet and account are already created
// Get native TON balance (in nanotons)
const balance = await account.getBalance()
console.log('Native TON balance:', balance, 'nanotons') // 1 TON = 1000000000 nanotons

// Get Jetton token balance
const jettonContract = 'EQ...' // Jetton contract address
const jettonBalance = await account.getTokenBalance(jettonContract);
console.log('Jetton balance:', jettonBalance);

// Note: TON client is required for balance checks
// Make sure wallet was created with a tonClient configuration

Read-Only Account

For addresses where you don't have the seed phrase:

import { WalletAccountReadOnlyTon } from '@tetherto/wdk-wallet-ton'

// Create a read-only account with public key
const publicKey = '...'; // Replace with the actual public key
const readOnlyAccount = new WalletAccountReadOnlyTon(publicKey, {
  tonClient: {
    url: 'https://toncenter.com/api/v3',
    secretKey: 'your-api-key' // Optional
  }
})

// Check native TON balance
const balance = await readOnlyAccount.getBalance()
console.log('Native balance:', balance, 'nanotons')

// Check Jetton token balance using contract
const jettonBalance = await readOnlyAccount.getTokenBalance('EQ...') // Example Jetton contract
console.log('Jetton balance:', jettonBalance)

// Note: Jetton balance checks use the standard Jetton wallet interface
// Make sure the contract address is correct and implements the Jetton standard

Sending Transactions

Send TON and estimate fees using WalletAccountTon. Requires TON Center client configuration.

// Send native TON
const result = await account.sendTransaction({
  to: 'EQ...', // Example TON address
  value: 1000000000n, // 1 TON in nanotons
  bounceable: true // Optional: specify if the address is bounceable
})
console.log('Transaction hash:', result.hash)
console.log('Transaction fee:', result.fee, 'nanotons')

// Get transaction fee estimate
const quote = await account.quoteSendTransaction({
  to: 'EQ...',
  value: 1000000000n,
  bounceable: true
});
console.log('Estimated fee:', quote.fee, 'nanotons');

Token Transfers

Transfer Jetton tokens and estimate fees using WalletAccountTon. Uses standard Jetton transfer function.

// Transfer Jetton tokens
const transferResult = await account.transfer({
  token: 'EQ...',      // Jetton contract address
  recipient: 'EQ...,  // Recipient's TON address
  amount: 1000000000n     // Amount in Jetton's base units (use BigInt for large numbers)
});
console.log('Transfer hash:', transferResult.hash);
console.log('Transfer fee:', transferResult.fee, 'nanotons');

// Quote token transfer fee
const transferQuote = await account.quoteTransfer({
  token: 'EQ...',      // Jetton contract address
  recipient: 'EQ...',  // Recipient's TON address
  amount: 1000000000n     // Amount in Jetton's base units
})
console.log('Transfer fee estimate:', transferQuote.fee, 'nanotons')

Message Signing and Verification

Sign and verify messages using WalletAccountTon.

// Sign a message
const message = 'Hello, TON!'
const signature = await account.sign(message)
console.log('Signature:', signature)

// Verify a signature
const isValid = await account.verify(message, signature)
console.log('Signature valid:', isValid)

Fee Management

Retrieve current fee rates using WalletManagerTon.

// Get current fee rates
const feeRates = await wallet.getFeeRates();
console.log('Normal fee rate:', feeRates.normal, 'nanotons');
console.log('Fast fee rate:', feeRates.fast, 'nanotons');

Memory Management

Clear sensitive data from memory using dispose methods in WalletAccountTon and WalletManagerTon.

// Dispose wallet accounts to clear private keys from memory
account.dispose()

// Dispose entire wallet manager
wallet.dispose()

🌐 Supported Networks

This package works with the TON blockchain, including:

• TON Mainnet
• TON Testnet

🔒 Security Considerations

• Seed Phrase Security: Always store your seed phrase securely and never share it
• Private Key Management: The package handles private keys internally with memory safety features
• Provider Security: Use trusted TON Center endpoints and consider running your own node for production
• Transaction Validation: Always validate transaction details before signing
• Memory Cleanup: Use the dispose() method to clear private keys from memory when done
• Fee Limits: Set transferMaxFee in config to prevent excessive transaction fees
• Address Validation: Be careful with bounceable vs non-bounceable addresses
• Gas Estimation: Always estimate gas before sending transactions
• Contract Interactions: Verify Jetton contract addresses before transfers
