On Optimistic Ethereum, Uniswap, the world's most popular decentralised exchange, has launched version 3. The alpha launch is a stripped-down version of the entire system that allows developers to progressively roll out the system and address any bugs that arise. Bankless founder David Hoffman said of the service, "It's quick and absurdly cheap." Synthetix, a DeFi platform, has also announced the introduction of Optimistic Ether for its layer two exchange starting July 26.
