Optimism developers have unveiled a roadmap plan to introduce native interoperability between Layer 2 chains in the ecosystem, including OP Mainnet, Zora, Base, and more. This will involve messaging protocols, universal token standards (SuperchainERC20), and error-proofing systems for secure asset transfers. The goal of the interoperability solution is to make the superchain run like a single blockchain - allowing users, assets, and developers to move seamlessly across networks. (The Block)
