**[Uniswap Labs Launches StablePair Hook Designed for Stablecoin Trading Pairs]** According to Golden Finance, on September 10, Uniswap Labs introduced "StablePair Hook," a new Uniswap v4 hook specifically designed for stablecoin trading pairs such as USDC/USDT and USDC/USDG. StablePair Hook utilizes dynamic fees instead of fixed fees, with the fees varying based on the deviation of the pool price from its reference price. When the price is close to the reference price, the mechanism adjusts the transaction fees for each trade to maintain a fixed spread between buy and sell prices. Uniswap Labs stated that if the price moves beyond the specified range, trades that push the price further out of the range will not incur any fees, as they already provide a favorable price for the pool. Trades that pull the price back to the reference price will adopt a Dutch auction mechanism. The transaction fee starts high and decreases with each block until a trader accepts it. This allows liquidity providers to earn more profits from price corrections. The first batch of StablePair Hook pools will be launched on Ethereum, with trading pairs USDC/USDG and USDC/USDT. Uniswap Labs noted that in the second quarter, stablecoin-to-stablecoin trading volume on the Uniswap platform reached $43.4 billion, surpassing the combined total of the second and third largest on-chain trading platforms.
