WLimitOrderHook

ArbitrumRegistered

A Uniswap v4 hook implementing single-tick limit orders with atomic swap + order placement. Users place orders by adding concentrated liquidity at a specific tick; when the pool price crosses that tick, the position is automatically filled. The swapAndPlaceOrder() function combines a swap and limit order placement in a single transaction, preventing front-running. Filled orders can be withdrawn at any time.
