Uniswap launched StablePair Hook, a dynamic fee rate to help LP capture the value of stablecoin transactions

According to The Block, Uniswap Labs announced the launch of a new tool, StablePair Hook, designed specifically for stablecoin trading pairs such as USDC/USDT and USDC/USDG.

Uniswap Labs stated that StablePair Hook can provide traders with consistent and predictable quotes, allowing liquidity providers to retain more of the value they create. Data shows that in the second quarter, the trading volume of exchanges between stablecoins on Uniswap reached $43.4 billion, surpassing the total of the other three major on-chain trading venues.

StablePair Hook replaces fixed rates with dynamic rates, which adjust based on the degree of price deviation from the reference price within the pool. When the price is close to the reference price, the Hook adjusts the transaction fee for each trade to maintain a fixed bid-ask spread; when the price deviates from the reference range, trades that push the price away incur no fees, while trades that pull the price back to the reference price use a Dutch auction mechanism, with fees decreasing block by block from high to low until accepted by the trader. Uniswap Labs stated that this allows liquidity providers to retain more value from price returns.

The first batch of StablePair Hook pools will go live on Ethereum, supporting USDC/USDG and USDC/USDT trading pairs. This Hook can be upgraded through Uniswap governance, and the fee system and other parameters can be adjusted without migrating liquidity.
