TREE NEWS update: Uniswap Labs introduced StablePair Hook, a Uniswap v4 hook built for stablecoin pairs such as USDC/USDT and USDC/USDG. The hook uses a dynamic fee instead of a fixed fee, adjusting each swap’s cost based on how far the pool price deviates from a reference price, and maintains a fixed spread between buy and sell prices when the price stays near that reference. Uniswap Labs said the design gives traders consistent, predictable quotes while letting LPs capture a larger share of the value they create.
Uniswap Labs Launches StablePair Hook for USDC/USDT Pairs
Stablecoin-to-stablecoin swaps are a high-volume, thin-margin business where fixed fees have long forced LPs to compete on little more than capital efficiency. A hook that prices deviation from a reference rather than charging a flat rate is a bid to make onchain stablecoin liquidity behave more like an order book, which matters most for the venues and market makers that treat these pairs as plumbing. Whether dynamic fees actually improve LP returns net of arbitrage, and whether other pools adopt the same reference logic, is the open question.
