Uniswap Labs launched StablePair Hook on September 10, a dynamic-fee hook for stable pairs on Uniswap v4 that goes live with two pools on Ethereum mainnet: USDC/USDG and USDC/USDT. The launch targets one of decentralized finance’s busiest corners, with the company saying stablecoin-to-stablecoin swaps reached $43.4 billion in the second quarter, more than the next three onchain venues combined, according to its announcement. The hook is the first upgradeable dynamic-fee design from Uniswap Labs, built to give liquidity providers a bigger share of the value they create.
