Overview
Base, Coinbase’s Ethereum L2, is reworking its technical foundations by transitioning away from Optimism’s OP Stack toward a unified, self-operated stack. The shift is framed as a way to move faster with upgrades and reduce overhead, but it also triggered an immediate market response in Optimism’s OP token and sparked debate about whether the “Superchain” vision of shared L2 infrastructure can hold if major participants prioritize sovereignty.
