SuperChain is a blockchain chain that consists of several chains. All of these chains get their security and interaction layer from the Optimism stack, and since they all have the same technical and communication technology, they do not need to bridge and switch networks. Current blockchains are disjointed and do not easily communicate with each other; but SuperChain can be likened to a large marketplace where many blockchains are found and connected to each other. SuperChain is similar to the Cosmos SDK; the difference is that now, with the OP stack, these blockchains are built on the Ethereum network and benefit from the benefits of a larger number of users and developers, liquidity and hybrid applications.
Of course, the Superchain concept has not yet been implemented; but Optimism intends to make it a reality.
