FoodySwap was demonstrated as a Uniswap v4 hook flow on Unichain Sepolia. The project uses the hook lifecycle to enforce commerce rules, dynamic pricing, settlement, and loyalty in an intent-driven payment flow.

Most AI commerce demos stop at suggestion. An AI can propose a payment or action, but nothing on-chain verifies whether the merchant is valid, whether the transaction should be allowed, or whether pricing and rewards should adapt to the user context. FoodySwap was inspired by the idea that AI commerce needs enforcement, not just intent generation. We built a Uniswap v4 hook that turns AI payment intent into programmable transaction rules for real-world commerce.
FoodySwap is unique because it moves commerce logic directly into the Uniswap v4 swap lifecycle. Instead of treating a swap as a generic token exchange, the hook enforces merchant validation, dynamic pricing, settlement, and loyalty on-chain. This creates a path from DeFi primitives to real-world programmable commerce, where AI agents, users, and merchants can interact through verifiable payment flows rather than off-chain promises.
The hardest part was translating a product-level commerce system into a clean hook-based on-chain architecture. We had to compress multiple responsibilities such as enforcement, pricing, settlement, and rewards into a valid Uniswap v4 hook design while keeping the trust boundary secure. Another challenge was making the system reproducible and understandable for judges through code, README documentation, tests, and a short demo video.
