Unpacking Uniswap's Unichain

Uniswap has announced Unichain, an OP Stack rollup with a Uniswap deployment that it hopes will become crypto's main liquidity hub. The article says the network plans to use a trusted execution environment secured by UNI validators, cutting user transaction wait times fourfold from 1 second to 200-250 milliseconds and enabling the UNI fee switch through staking. The Unichain testnet launched first, with mainnet expected later in the year. The article also notes that about 80% of Uniswap's TVL remained in its Ethereum-based smart contracts at the time of analysis, so liquidity providers may not migrate automatically.
