DEX Arbitrage & Cross-chain Bridge

Developed a sophisticated, high-performance automated trading bot designed to identify and execute risk-minimizing arbitrage opportunities across decentralized exchanges (DEXs) on leading Ethereum Layer 2 networks. The bot performs real-time market scanning, on-chain data analysis, and executes profitable trades while dynamically accounting for network gas fees and slippage.

Key Features:
Real-Time Multi-Chain Monitoring: Simultaneous price and liquidity tracking across Base, Arbitrum, and Optimism networks.

DEX Aggregator Integration: Leverages the Odos API to source the most efficient swap paths, ensuring optimal execution prices and minimal protocol fees.

11+ Asset Support: Monitors liquidity for major pairs including ETH, USDC, USDT, WBTC, cbBTC (Coinbase Wrapped BTC), LINK, UNI, and others.

Cross-Chain Bridge Module (Across Protocol): Features an automated capital consolidation module that bridges profits from source chains back to a central operational chain (Optimism) using cheap and fast bridges.

Smart Profit Calculation: Advanced algorithm that automatically deducts dynamic gas fees from potential spread profits. Trades are only executed when a predefined net profit threshold is met.

Telegram Notification System: Full integration with the Telegram API for real-time alerts on portfolio status, market conditions, and detailed trade execution reports.

Technical Stack:
Language: Python 3.10+

Core Libraries: Web3.py (blockchain interaction), Requests (API connectivity), Telebot (interface), Threading (concurrency).

Networks: Ethereum Layer 2 (Base, Arbitrum, Optimism).

Infrastructure: Private RPC nodes, REST APIs (Binance, Odos, Across Protocol).

Deliverables:
A stable, production-ready trading tool operating 24/7 in the background. It effectively filters out unprofitable trades, manages gas costs dynamically, and provides the user with complete portfolio transparency through a convenient Telegram interface.
