The price of Optimism's native token, OP, has fallen by over 20% in the past 24 hours after Layer 2 solution Base announced its transition from the OP Stack to its self-running unified technology stack, base/base. Base stated that this move aims to accelerate development and reduce system complexity, and future node operators will need to migrate to the Base client to accommodate the hard fork. Base launched as the OP Stack chain in 2023, and according to a previous agreement, a portion of its sorter revenue was to be deposited into the Optimism treasury. With Base's shift to an independent architecture, this revenue stream will be retained by Base itself. Currently, OP is trading at $0.1436, a drop of approximately 97% from its all-time high of $4.84 in 2024. In contrast, Base has not yet issued any tokens.
