Uniswap Labs just dropped StablePair Hook—a new module for Uniswap v4 that tweaks trading fees based on how far a pool's price drifts from its reference rate. According to the team, this setup helps redirect some of the revenue that usually gets scooped up by arbitrage bots back to liquidity providers. The first pools to go live are USDC/USDT and USDC/USDG on Ethereum.

What’s StablePair Hook?

StablePair Hook brings in a dynamic fee model: if a pair’s price strays from its target, the fee automatically adjusts. This is built for stablecoin pairs where sticking close to a reference price is key.

Why Liquidity Providers Care

Uniswap Labs says the dynamic fee system should boost liquidity provider earnings by shifting a chunk of the arbitrage margin their way.

Which Pools Are Live?

With StablePair Hook now on Ethereum, the first available pools are USDC/USDT and USDC/USDG. The feature is aimed at pairs with a stable reference rate.
