Uniswap Hooks Up Liquidity Providers with New Dynamic-Fee Design
Uniswap Labs launched StablePair Hook on September 10, aiming to change the way stablecoin pairs are traded. This dynamic-fee hook for stable pairs on Uniswap v4 has gone live with two pools on Ethereum mainnet: USDC/USDG and USDC/USDT. According to its announcement, stablecoin-to-stablecoin swaps reached $43.4 billion in the second quarter, more than the next three onchain venues combined.
The hook replaces a fixed fee with one that measures how far a pool has drifted from a reference rate and adjusts on every swap. Inside a tight band, the fee moves to quote a fixed bid-ask spread; once the price drifts outside it, swaps that push it further away pay no fee, while corrections run through a Dutch auction that starts high and drops each block until someone takes it.
This upgradeable dynamic-fee design is built to give liquidity providers a bigger share of the value they create. Pool parameters and fee logic can be upgraded through Uniswap Governance without forcing liquidity providers to migrate, which the team framed as a way to improve the mechanism as usage grows.
