Plain Finance's integration with Uniswap represents a strategic alignment, essential for the liquidity and exchange of tokenised real-world assets (RWAs). Our protocol facilitates the tokenisation of property ownership, allowing investors to acquire digital tokens representing shares in real estate entities. This process transitions ownership verification to the blockchain, enabling the custodian's reimbursement through on-chain transactions.  A critical aspect of tokenisation is providing a mechanism for liquid asset exchange. Uniswap v3, known for its decentralised exchange capabilities, offers a foundational platform for this purpose. However, Uniswap v3 introduces range-based liquidity provision, which, while innovative, presents challenges in pools with lower liquidity — a common scenario for residential real-estate tokens where each pool's liquidity is inherently limited to approximately twice the property's value. This range restriction necessitates active position management by liquidity providers (LPs), exposing them to an increased risk of impermanent loss in these smaller pools.  Uniswap v4, with its advanced features, particularly the hooks capabilities, emerges as a superior choice for Plain Finance. It allows for the creation of full-range liquidity pools, integrating rental income directly into liquidity providers' positions, thereby enhancing the efficiency and attractiveness of participating in the RWA market. Moreover, Uniswap v4's streamlined swap routing via a single PoolManager.sol Smart Contract optimises transaction efficiency, enabling seamless asset exchanges across properties with minimal fees. This compatibility not only supports liquidation needs but also elevates the potential for RWAs within the Uniswap ecosystem, aligning with our vision for accessible, efficient property investment and exchange on the blockchain.
