Uniswap's Layer 2 network Unichain announced it will migrate to OP Enterprise to prepare for native interoperability within the OP Stack ecosystem. This upgrade will enable users to transfer assets between OP Stack chains without cross-chain bridges, with initial support for ETH transactions. The migration schedule begins with the testnet transition on October 13, followed by the mainnet migration planned for late October. The move positions Unichain to leverage native cross-chain functionality as part of the broader Optimism ecosystem integration.
