The original revenue-sharing arrangement was tied to Base’s participation in the Superchain. As part of the transition to a Base-operated stack, the prior Superchain revenue share will not continue.
When Base joined the Superchain in 2023, they emphasized long-term alignment as a reflection of their good faith intent at the time. As we’ve made clear in the past, however, Base’s continued participation in the Superchain was never a given, and like any relationship, the one between Base and the Optimism Collective can change over time. This transition reflects that natural evolution.
Base’s token grant was contingent on continued participation in the Superchain. Therefore, Base is not entitled to the unvested portion of the OP grant it received in 2023.
The 9% voting cap continues to apply to Base.
The agreement for Base to continue its relationship as an OP Enterprise customer was negotiated between the Optimism Foundation and Base, just like the original Superchain revshare agreement. Note that the recently approved buyback program applies to incoming Superchain revenue for 2026, so OP Enterprise revenue will fall outside the scope of the buyback program. This may evolve as part of future restructuring as mentioned in the Season 9 blog post.
