 Interoperability is the ability for a blockchain to securely read the state of another blockchain. 
-Native OP Stack interoperability provides the ability to read messages and transfer assets across the Superchain (without having to go through L1) via low-latency, secure message passing. This results in the following benefits:

 *   1-block latency asset movement that is both maximally capital efficient and non-fragmenting 
 *   improved user experience for developers on the Superchain
 *   secure transfer of ETH and ERC-20s across L2s
