Three hidden flaws in Uniswap’s StablePair hook drain LP returns
Uniswap’s StablePair v4 hook charges swaps based on their direction relative to a configured reference rate, aiming to capture rebalancing value for liquidity providers. Its rules can make corrective trades cheaper over time, while trades classified as moving away from the benchmark may pay no LP fee. Because the hook uses a cached pool price and does not consult external market prices, a depeg or mid-block price shift could cause trades reflecting genuine price discovery to be classified incorrectly. Fees do not protect providers from losses in token value or from ending up with more of a weakening asset. Uniswap governance can change fee settings and upgrade the hook, though documented permission limits prevent upgrades from blocking withdrawals or altering swap amounts to skim fees. Available pool statistics do not establish superior LP returns.
