Uniswap’s StablePair fee hook is designed to keep more of the value from rebalancing stablecoin pools with liquidity providers.
Yet the rule deciding which trade counts as a correction depends on a configured reference rate.
StablePair is a Uniswap v4 hook, a contract that changes a pool’s behavior. Its fee logic compares a cached pool price with a reference stored in the hook’s configuration. The design prices trades around that benchmark, leaving providers exposed if a token’s economic value moves away.
