SOLVING INTEROPERABILITY FOR THE SUPERCHAIN AND BEYOND

Summary from the TLDR Crypto newsletter

Optimism has announced its vision for native interoperability across the Superchain-connected L2s, allowing users and assets to move seamlessly across the Superchain. There will be a cross-chain message passing protocol, a universal token standard, and a shared proof system for shared security. Beyond the Superchain, ERC-7683 will allow for interoperability with other L2s via the app layer. Interoperability will be live on the mainnet next year.
