Into the Dark Forest: Engineering Working DeFi Arbitrage
- A researcher at Paradigm, Dan Robinson, encountered a distress call on Uniswap Discord, reflecting a lost $12,000. He tried to rescue the tokens but was outsmarted by bots, leading him to term Ethereum as a Dark Forest.
- The Dark Forest of decentralized finance (DeFi) operates on Automated Market Makers (AMMs), shifting from traditional order books to liquidity pools. Uniswap's constant product formula determines asset prices within the AMMs.
- Arbitrage in DeFi involves exploiting price discrepancies between AMMs or between AMMs and Centralized Exchanges. Types include simple arbitrage, triangular arbitrage, and flash loan arbitrage.
- Challenges in DeFi arbitrage include gas fees, slippage, latency, frontrunning, and MEV. Advanced strategies like leveraging MEV-Boost relays or operating on Layer 2 blockchains help mitigate risks.
- The architectural design of an arbitrage bot in DeFi involves real-time data reading, market mapping, arbitrage strategy evaluation, transaction construction, and post-execution validation.
- Calculations in arbitrage bot operations involve handling precision with BigInt, using the Bellman-Ford algorithm for arbitrage path detection, and optimizing input amounts convexly for profitability.
- Simulated swaps and profitability assessments are crucial before executing trades. The bot dynamically selects between direct swaps and flash loans based on the arbitrage opportunity size.
- In the Dark Forest, transaction engineering focuses on speed, security, and reliability. Operating on Layer 2 chains like Base provides a more secure environment, while high-performance node connections are essential.
- Ethical considerations in DeFi arbitrage include protecting less sophisticated users, combating scams with Bloom filters, and advocating for user education and security audits.
- The challenges and evolving landscape of DeFi arbitrage underscore the need for continuous adaptation and rapid response. Newer AMM models and cross-chain arbitrage present further opportunities in this high-stakes environment.
- Overall, the journey of engineering an arbitrage bot in DeFi highlights the complexities, challenges, and ethical nuances of navigating the Dark Forest, where success requires precision, speed, and adaptability.
