Superchain revenue and the OP token buyback program

Base exit and revenue impacts

Base transitioned away from the OP Stack on February 18, 2026, to build a unified codebase called base/base. This move hollowed out the Superchain revenue model. In January 2026, Base provided roughly 90% of all Superchain sequencer income. The Optimism Collective collected 8,387 ETH, worth about $16.4 million, from Base during the partnership. The remaining Superchain chains, including Zora, Mode, Mint, Unichain, Ink, World Chain, and Soneium, produce only a fraction of the revenue Base generated. The Superchain includes networks like World Chain and Soneium, which participate in the shared governance model. This revenue decline directly impacts the monthly OP token buyback program. The Optimism Foundation approved a proposal on January 22, 2026, to use 50% of incoming Superchain revenue to buy OP tokens starting in February. The Superchain captures 61.4% of the Layer-2 fee market and processes 13% of all crypto transactions. In the past twelve months, Optimism collected 5,868 ETH in revenue. However, the loss of its largest contributor makes the flywheel mechanism fragile. The buyback program uses an OTC provider to convert ETH to OP monthly. The program pauses if monthly revenue falls below $200,000 or if the OTC provider cannot execute under the maximum allowable fee spreads.

Token economics and the flywheel

The OP token value ties to the success of the Superchain federation. In 2025, Base generated $75.4 million in revenue and $55 million in profit. The Superchain fee split requires chains to pay the greater of 2.5% of total revenue or 15% of on-chain profit, where on-chain profit is defined as fee revenue minus L1 gas fees. Because Base held the largest market share, its departure leaves the buyback program with much less liquidity to create demand for OP. The buyback program uses an OTC provider to convert ETH to OP monthly. The OP token has a maximum supply of 4,294,967,296 tokens, with 2,117,847,344 tokens currently in circulation. Holders participate in the Optimism Collective through a dual-house governance structure consisting of the Token House and the Citizens’ House. The Token House manages technical decisions and incentive distribution, while the Citizens’ House handles public goods funding through RetroPGF. As of late September 2026, the OP token trades at approximately $0.105. This price sits far below the March 2024 all-time high of $4.85. You should recognize that the buyback mechanism depends entirely on the aggregate activity of many smaller chains. Optimism also manages a treasury that supports development through grants.

The program was designed as a 12-month pilot to create structural demand for the token. The deal between Coinbase and Optimism previously involved 118 million OP tokens that vest over six years in exchange for Base’s sequencer revenue. The Interop Layer, which targets one-block cross-chain messaging, aims to reduce liquidity fragmentation across the remaining chains.

The fragility of shared infrastructure

The Superchain model assumed that shared infrastructure and revenue would benefit all participants equally. This thesis failed when the largest contributor decided that paying into the Collective outweighed the benefits of shared development. Base operates a single centralized sequencer with a Nakamoto coefficient of 1. This centralization allows Coinbase to control upgrades and implementation speeds without multi-team coordination. The departure of Base proves that a massive power asymmetry can break the economic incentives of a shared stack. The transition to the base/base repository allows for six hard forks per year. Base achieves 2-second block times and 112 transactions per second while maintaining a 3.5-day challenge window for fraud proofs. The Superchain roadmap relies on the Interop Layer to enable native, trust-minimized messaging between networks. Will the Optimism Collective survive the exodus of its primary revenue source?
