Payment processing library for tg-shops.

TMA Authenticator

Python library for Telegram Mini App (TMA) and Web3 TON wallet authentication.

Features

• 🔐 TMA Authentication: Telegram Mini App user authentication
• 🌐 Web3 TON Authentication: TON wallet authentication via TON Connect
• 🔑 JWT Token Generation: Secure token generation for both auth methods
• 🔗 Unified Authentication: Single endpoint supporting TMA, Web3, and service tokens
• 💾 Caching: Built-in caching for nonces and tokens
• ✅ Full Test Coverage: Comprehensive test suite
• 📚 Type Hints: Full type annotation support

Installation

pip install tma-authenticator

Or from source:

git clone https://github.com/your-repo/python-tma-authorization
cd python-tma-authorization
pip install -e .

Quick Start

TMA Authentication

from tma_authenticator.tma_authentication_router import TMAAuthenticationRouter
from tma_authenticator.tma_authenticator import TMAAuthenticator
from database.users import UsersDatabase
from config import TELEGRAM_BOT_TOKEN, IMPERSONATE_ADMIN_PASSWORD

user_database: UsersDatabase = UsersDatabase()
authenticator = TMAAuthenticator(TELEGRAM_BOT_TOKEN, IMPERSONATE_ADMIN_PASSWORD, user_database)
authentication_router = authenticator.authentication_router

Web3 TON Authentication

from fastapi import FastAPI
from aiocache import Cache
from tma_authenticator.web3_ton_router import Web3TonRouter

app = FastAPI()

# Setup cache
Cache.from_url("memory://")

# Create Web3 TON router
web3_router = Web3TonRouter(
    jwt_secret="your-super-secret-jwt-key",
    jwt_algorithm="HS256",
    jwt_expiration_minutes=60,
    nonce_ttl_seconds=300,
)

# Include router
app.include_router(web3_router)

Unified Authentication

The TMAAuthenticator supports three authentication methods that can be used independently or combined:

1. TMA Authorization (Authorization header) - Telegram Mini App token
2. Service Token (X-Service-Token header) - Service-to-service JWT
3. Web3 Token (X-Web3-Token header) - Wallet-based JWT (NEW)

Web3 Token Authentication

from tma_authenticator import TMAAuthenticator

authenticator = TMAAuthenticator(
    service_name="my-app",
    bot_token="YOUR_BOT_TOKEN",
    auth_url="https://auth-service.com",
    storage_provider=storage,
    jwt_secret="your-secret-key",  # Enable Web3 support
    jwt_algorithm="HS256"
)

@app.get("/protected")
async def protected_route(user = Depends(authenticator.oauth_verify_token)):
    # Accepts any of the three token types
    return {
        "user_id": user.tg_id,
        "username": user.username,
        "wallet": user.wallet_address  # Present when Web3 token is used
    }

Usage:

# Web3 token only
curl -H "X-Web3-Token: Bearer <JWT>" https://api.example.com/protected

# TMA + Web3 (combine Telegram identity with wallet)
curl -H "Authorization: Bearer <TMA_TOKEN>" \
     -H "X-Web3-Token: Bearer <WEB3_JWT>" \
     https://api.example.com/protected

See WEB3_TOKEN_AUTHENTICATION.md for complete documentation.

Web3 TON Authentication

The library now supports TON wallet authentication following the TON Connect 2.0 specification.

Available Endpoints

1. GET /.well-known/jwks.json - JWKS public keys endpoint
2. GET /web3/nonce?wallet=<address> - Generate nonce for wallet
3. POST /web3/ton/check-proof - Verify TON proof and get JWT token

Authentication Flow

1. Client requests nonce: GET /web3/nonce?wallet=0:abc...
2. Client signs proof with TON wallet using TON Connect
3. Client submits proof: POST /web3/ton/check-proof
4. Server verifies proof and returns JWT token
5. Client uses JWT token for authenticated requests

Example Usage

See WEB3_TON_AUTH.md for complete documentation and examples.

Quick example:

# Step 1: Get nonce
curl "http://localhost:8000/web3/nonce?wallet=0:0e911c7..."

# Step 2: Submit proof (after signing with wallet)
curl -X POST "http://localhost:8000/web3/ton/check-proof" \
  -H "Content-Type: application/json" \
  -d '{
    "ton_addr": {
      "address": "0:0e911c7...",
      "network": "-3",
      "publicKey": "b3e155...",
      "walletStateInit": "te6cc..."
    },
    "ton_proof": {
      "proof": {
        "domain": {"lengthBytes": 4, "value": "t.me"},
        "payload": "2025-12-22T14:55:08.825Z",
        "signature": "360QU7...",
        "timestamp": 1734876508
      }
    }
  }'
