The OP Stack framed rollups as reusable infrastructure
Optimism’s OP Stack is a collection of software components for building Ethereum-compatible rollups, with the Superchain vision linking multiple chains.
Shared infrastructure can reduce duplicated engineering and make interoperability a deliberate design target.
The ecosystem began competing not only on one chain’s fees but also on developer tools, governance and cross-chain coordination.
A common stack does not automatically create seamless security or liquidity; each deployment retains configuration choices and risks.
