Uniswap introduced Unichain, a DeFi-focused L2 built on the OP Stack. Unichain is now live on testnet with a mainnet launch planned later this year. Unichain will be part of the Superchain and Uniswap Labs will become a core contributor to the OP Stack. Unichain will also support native Superchain Interoperability. Native interoperability enables seamless cross-chain message-passing between OP Stack chains. The SuperchainERC20 standard will eliminate the need for multiple bridged asset versions. Unichain will also support cross-chain intents standard ERC-7683, extending interoperability to the broader Ethereum ecosystem. Unichain features an initial 1-second confirmation time, which helps mitigate MEV. By having faster block times, the chain creates more stable market conditions, thereby reducing opportunities for MEV exploitation. According to Uniswap, Unichain will be approximately 95% cheaper than Ethereum L1. This story was featured in Episode 571.
