SwapBook
P2P order book running on EigenLayer that settles transactions on-chain. Uniswap hook integration: a swap is caught before it happens and rerouted to the order book if the price is better.

About
The problem it solves Order books match buyers and sellers perfectly, but blockchains can’t handle them. AMMs are the workaround—clunky, expensive, and loss-prone. We use an EigenLayer AVS to run an order book off-chain, have validators reach consensus on how to process each order, and have settlement on-chain. User Interaction and Data Flow Please see README on GitHub repo to try it out and watch the **demo video**. The project architecture and development process An order is submitted to a network of validors (an AVS using the Othentic framework), which each process the order in their local instance of the given currency pair's order book, and once they reach a consensus, settlement occurs on-chain. We integrate with a Uniswap V4 hook to catch AMM orders before they happen and, if the user can get a better price on our order book than they can through the pool, their order is rerouted to the order book instead. Additional Features Built for the EigenGames hackathon (run in parallel to the BUIDLathon).
