Using Predicate, the Paxos liquidity pool on Uniswap enforces a custom policy enforced via frontend IP gating or onchain attestations.

Predicate hooks enable the USDL liquidity pool on Uniswap to enforce Paxos’s custom compliance policy via front-end IP gating or on-chain attestations, while a second hook automatically wraps USDL into a non-rebasing token so it remains compatible with Uniswap’s accounting model and broader DeFi composability.
