Uniswap Labs Launches StablePair Hook for Dynamic Fee Adjustment
Uniswap Labs has launched StablePair Hook, a dynamic-fee mechanism designed for stable pairs on Uniswap v4. The new hook aims to bring value back into the pool by adjusting fees based on price drift from its true rate or reference price.
The mechanism measures how far the pool has drifted from its true rate and sets the fee accordingly. Inside a tight band around the rate, the fee adjusts under every swap to quote a fixed bid/ask spread. Once the price drifts outside that band, swaps that push the price further off pay no fee.
StablePair Hook is designed to evolve over time with usage and can be upgraded through Uniswap Governance without pools needing to migrate. The hook joins other Uniswap Labs products such as DualPool, Permissioned Pools, and LitePSM, which are being developed in collaboration with issuers and LPs.
Stable pairs have seen significant trading volume on the Uniswap Protocol, reaching $43.4 billion in stablecoin-to-stablecoin swaps alone in the second quarter of 2026. This represents more than the next three on-chain venues combined.
