Unified Liquidity Framework for Layer 2 Scaling Solutions via Uniswap V4 Pools

1. Introduction
The current Layer 2 (L2) solutions enhance scalability but result in fragmented liquidity. This proposal envisions a pooled liquidity model utilizing Uniswap V4's innovative hook system. By locking funds in a single Uniswap V4 pool contract, we can streamline the transfer of assets between L2 networks without reverting to Layer 1 (L1) for each transaction. The only requirement is the verification of funds to prevent double spending or bridging, ensuring assets remain secured in the pool contract.
2. The Bridging Mechanism
The proposed bridging mechanism is straightforward: users deposit assets into a designated Uniswap V4 pool, which serves as a gateway to L2 networks. The deposited funds are then locked, and users generate a cryptographic proof of their action. This proof, which certifies the uniqueness of the transaction and the non-duplication of assets, enables the reconsti
