Summary

Base, incubated by Coinbase, said on Feb. 19 it will exit Optimism’s Superchain and transition off the OP Stack to a unified, self-managed tech stack, removing dependencies on Flashbots and Paradigm. OP fell over 23% in 24 hours to $0.1423, according to HTX. Base has historically contributed the vast majority of revenue to Optimism’s Superchain, providing context for the token’s sharp move.

Terms & Concepts
  • OP Stack: Optimism’s modular rollup framework that powers OP-based chains (e.g., Base), providing shared code to scale Ethereum.
  • Optimism Superchain: A network of interconnected OP Stack–based layer-2 chains coordinated by the Optimism Collective.
  • Layer-2: A secondary network built atop Ethereum to increase throughput and reduce fees by processing transactions off-chain.
