Uniswap Launches StablePair Hook for USDC and USDT Liquidity

Uniswap Labs announced the launch of its StablePair Hook on Ethereum mainnet on September 10, 2026, initially supporting USDC/USDG and USDC/USDT pools. The Uniswap v4 feature changes fees in response to how far a pool price has moved from its configured reference rate and whether a trade helps move it back. Uniswap Labs presented the rollout as a fee-model redesign for stablecoin liquidity, where small price differences can create substantial trading activity.
The launch addresses a specific feature of stablecoin markets: assets intended to trade near the same value can still periodically move apart. StablePair is designed to make the price and direction of those deviations part of the fee calculation, rather than applying one static fee irrespective of market conditions.
