According to Milk Road, Uniswap has launched Unichain to mitigate the high Ethereum gas fees that previously led to a $73M loss in Q4 last year. Unichain, featuring 1-second block times, aims to optimize transaction efficiency and ensure more profits reach liquidity providers. This strategic move reflects a growing trend where decentralized apps (dApps) establish their own appchains to enhance performance and reduce costs.
