Uniswap Labs, the team behind the decentralized exchange protocol, has launched "StablePair Hook," a new Uniswap v4 hook designed for stablecoin trading pairs such as USDC/USDT and USDC/USDG. The tool uses dynamic fees that adjust based on how far the pool price moves from its reference price, allowing liquidity providers to keep more profit from bringing prices back to parity. Stablecoin-to-stablecoin swaps on Uniswap reached $43.4 billion in the second quarter, surpassing the next three onchain venues combined. The first StablePair Hook pools are launching on Ethereum with USDC/USDG and USDC/USDT.
