Uniswap founder Hayden Adams said in a social media post, "About 12 hours after launching Uniswap V4, testing the exchange of $1000 ETH to USDT exchange. Our on-chain routing recommends the ETH to USDC to USDT token exchange through two V4 pools at the sum of $400,000 TVL as the best price. Even if the V3 version of the ETH/USDT single liquidity pool TVL totals about $150 million, the benefits of pure gas efficiency are starting to show (lower cost for native ETH tokens + multiple loop routes), and IMO will be one of the biggest catalysts for V4 growth, lower gas costs, better exchange prices, more LP profits."
