I need a Solidity smart contract deployed on Ethereum that requests a flash loan from Aave, sweeps the borrowed funds through Uniswap and SushiSwap in the same transaction, captures any price-spread profit, then repays the loan with fees before the block closes. The core logic should be gas-efficient, re-entrancy-safe, and written so I can adjust token pairs or add new DEX routers later. Please supply: • A fully commented .sol file showing the Aave flash-loan call, the two-leg swap sequence (Uniswap → SushiSwap or the reverse, chosen dynamically), and the automatic repayment. • A deployment script and a short README explaining environment variables, contract parameters, and how to point to mainnet or a mainnet-fork for testing (Hardhat or Foundry is fine). • One automated test that forks mainnet, triggers a sample arbitrage, and proves the contract ends the tx with a positive balance after fees. If anything about Aave’s v3 pool, Uniswap’s or SushiSwap’s router versions affects the implementation, note it clearly in the code comments.

Hello, I can develop the Solidity smart contract you need to perform flash loans on Aave while arbitraging between Uniswap and SushiSwap. The contract will be gas-efficient, re-entrancy-safe, and modular so you can easily change token pairs or add DEX routers. I will provide a fully commented .sol file with the flash loan logic, a deployment script, and a clear README for mainnet or fork testing. Also, I'll implement a mainnet-fork test showing the contract captures profit after fees from a sample arbitrage. Thanks, Teo

As a Principal Architect leveraging over 14 years in software architecture and engineering, my focus has been on building robust, secure and efficient solutions - very much like your requirement for a Solidity smart contract. Although I may not have any direct experience with Ethereum or Aave, my proficiency in handling cutting-edge technologies like Flutter and React Native and their integration with AI and cloud systems is highly transferrable. Being the architect behind more than 50 successful apps worldwide, including B2B/SaaS platforms, I understand that even a minor coding error can cause substantial losses. However, with my strong track record of delivering meticulously detailed solutions, you can be certain that not only would your flash loan project be entirely commented but also tested for any potential vulnerability on mainnet using Hardhat or Foundry. In addition to my technical skills, one of my core strengths is building collaborative relationships with clients. Consider me your tech co-founder, dedicated to bringing your vision of utilizing flash loans from Aave to maximize profits from Uniswap and SushiSwap into reality. I am committed to understanding your needs deeply and offering comprehensive end-to-end assistance from wire-framing to deployment, ensuring complete satisfaction while maintaining utmost transparency and professionalism.
