Coinbase shifts Base to unified in-house tech stack, reducing reliance on Optimism

Coinbase plans to migrate Base onto a unified, internally managed software stack that replaces its prior dependence on Optimism's core technology and external tooling. The move will let Base package its own client binary, target up to six hard forks per year, and introduce Base-specific governance, security council signers, and fee systems. As Base gains more control over upgrades and infrastructure, Optimism faces reduced influence over one of its largest Layer 2 ecosystem partners.
