Golden Finance reported that Optimism developers have announced a roadmap plan to build an interoperability communication layer between Layer2 chains in its Superchain ecosystem, which will include a messaging protocol, a Superchain token standard (SuperchainERC20), interoperable fault proofs, and a set of interoperable chains. Optimism said that the development network of the messaging protocol is preparing for its upcoming release. After the development network phase is completed, the test network of the messaging protocol and token standard will be launched and finally launched on the mainnet. Optimism said that the technical vision is committed not only to solving the interoperability of Superchain, but also to solving the interoperability of the broader Ethereum to ensure a consistent user experience in different ecosystems.
