"""
Axiom Trade Token Monitor Telegram Bot

This bot monitors new Solana tokens from Axiom Trade and sends formatted updates
to a Telegram channel/chat. It displays comprehensive token information including
FDV, volume, holders, and social links - similar to popular meme coin trackers.

Features:
- Real-time token monitoring via WebSocket
- Formatted token information with emojis
- Social links integration (Twitter, Telegram, Website)
- Token age tracking
- Holder statistics and distribution
- Volume and market cap data
- Error handling and reconnection logic

Requirements:
- python-telegram-bot
- axiomtradeapi
- python-dotenv

Setup:
1. Create a bot via @BotFather on Telegram
2. Add bot token to .env file
3. Add your chat/channel ID to .env file
4. Add Axiom Trade API tokens to .env file
5. Run the bot: python telegram_token_bot.py
