The TON Library (TonLib) is a powerful addition to TeleBot Creator that enables seamless integration with The Open Network blockchain. With TonLib, you can create wallets, check balances, send TON, work with jettons (TON's tokens), and integrate TON Connect for user wallet connections.
Note: This is a development version of the TON Library introduced in version 4.9.0. Most bugs have been fixed and the library is stable for production use.
Getting Started
Unlike other libraries, TonLib doesn't require an import statement. It's globally available in your bot code.
# ❌ Don't use imports
# import TonLib # This will cause an error
# ✅ Instead, use the library directly
wallet = libs.TonLib.generateWallet()
Core Functions
Wallet Management
generateWallet()
Creates a new TON wallet and returns its address and mnemonic phrase.
result = libs.TonLib.generateWallet()
address = result["address"]
mnemonics = result["mnemonics"]
setKeys(mnemonics)
Stores a mnemonic phrase for later use.
libs.TonLib.setKeys("word1 word2 ... word24")
getWalletAddress(mnemonics=None)
Retrieves the wallet address from a mnemonic phrase or from stored keys.
# Using stored keys
address = libs.TonLib.getWalletAddress()
# Or with specific mnemonics
address = libs.TonLib.getWalletAddress("word1 word2 ... word24")
transactions = libs.TonLib.checkTONTransaction("EQD...")
for tx in transactions:
if tx["type"] == "incoming":
from_address = tx["from"]
amount = tx["amount"]
# Process the incoming transaction...
Creates a TON Connect session for wallet connection.
session = libs.TonLib.create_ton_connect_session(user_id="12345")
connect_url = session["connect_url"]
# Send this URL to the user for connection
verify_ton_connect_session(session_id)
Checks if a wallet has connected to the session.
status = libs.TonLib.verify_ton_connect_session(session_id)
if status["status"] == "connected":
wallet_address = status["wallet_address"]
# User wallet is connected
request = libs.TonLib.request_ton_transaction(
to_address="EQD...",
amount=1.5,
comment="Donation",
callback_url="https://your-app.com/callback"
)
# Send the request["connect_url"] to the user
def handle_start(message):
# Generate a new wallet
wallet = libs.TonLib.generateWallet()
# Store the mnemonics
libs.TonLib.setKeys(wallet["mnemonics"])
# Send information to the user
bot.send_message(
chat_id=message.chat.id,
text=f"Your new TON wallet address:\n`{wallet['address']}`\n\n"
f"Seed phrase (keep it safe):\n`{wallet['mnemonics']}`",
parse_mode="Markdown"
)
def handle_balance(message):
# Get wallet address
address = libs.TonLib.getWalletAddress()
# Get balance
balance = libs.TonLib.getBalance(address)
# Send balance to user
bot.send_message(
chat_id=message.chat.id,
text=f"Your balance: {balance} TON"
)
TON Connect Integration Example
# Step 1: Initialize wallet connection
def handle_connect_wallet(message):
user_id = str(message.from_user.id)
session = libs.TonLib.create_ton_connect_session(user_id)
# Store session_id for later verification
db.set_user_data(user_id, "ton_session_id", session["session_id"])
# Send connection link to user
bot.send_message(
chat_id=message.chat.id,
text=f"Connect your TON wallet by opening this link:\n{session['connect_url']}"
)
# Step 2: Check wallet connection status
def handle_check_connection(message):
user_id = str(message.from_user.id)
session_id = db.get_user_data(user_id, "ton_session_id")
if not session_id:
return bot.send_message(message.chat.id, "You haven't started a connection yet")
status = libs.TonLib.verify_ton_connect_session(session_id)
if status["status"] == "connected":
bot.send_message(
chat_id=message.chat.id,
text=f"Wallet connected: {status['wallet_address']}"
)
else:
bot.send_message(
chat_id=message.chat.id,
text="Wallet not connected yet. Try again later."
)
Best Practices
Security: Never store sensitive mnemonic phrases in plain text. Consider encrypting them or using a secure key management solution.
Error Handling: Always wrap TON operations in try/except blocks to handle potential errors gracefully.
Testnet First: When developing, use the testnet (is_testnet=True) before moving to mainnet.
Rate Limiting: Be mindful of API request limits when checking balances or transactions frequently.
User Experience: Provide clear instructions and feedback to users, especially for wallet connection steps.
Limitations
Maximum code execution time is 120 seconds
time.sleep() function is limited to 10 seconds maximum
