Base's announcement to transition from the OP Stack to its own tech stack, base/base, has led to a significant decline in Optimism's native token, OP, which fell over 20% in the last 24 hours. The move is intended to streamline development and reduce complexity, with future node operators required to migrate to the Base client ahead of a planned hard fork. Previously, Base, launched in 2023, shared a portion of its sequencer revenues with the Optimism treasury, but will now retain these revenues under its new independent architecture. The OP token is currently trading at $0.1436, marking a steep decline of approximately 97% from its all-time high of $4.84 in 2024. Meanwhile, Base has yet to issue its own token.
