· High Revenue Concentration: In 2025, Base contributed approximately 71% of the sequencer revenue for the Superchain. This trend is intensifying, yet the proportion Coinbase pays to Optimism remains fixed at 2.5%.

· Price and Ecosystem Diverge: The OP token has plummeted 93% from its all-time high ($4.84 → $0.32), while Base's Total Value Locked (TVL) grew by 48% ($3.1B → $5B) over the same period. The market has realized that Base's growth does not benefit OP holders but has not yet considered the risk of Base potentially exiting.

· Zero Technical Barrier: The OP Stack uses the MIT open-source license, meaning Coinbase can fork it at any time. The only current tie keeping Base in the Superchain is governance relations, and a BASE token with independent governance rights would sever this link entirely.

· Fragile Alliance: Optimism gifted Base 118 million OP tokens to ensure long-term cooperation but limited its voting power to 9% of the total supply. This is not true alignment of interests but a minority stake with an 'exit option.' If renegotiation causes the OP price to fall, Coinbase abandoning the value of this grant in exchange for canceling the revenue share would be a profitable trade.

Coinbase's L2 network, Base, contributed approximately 71% of the Superchain's sequencer revenue in 2025 but paid only 2.5% of that to the Optimism Collective. The OP Stack uses the MIT open-source license—technically and legally, nothing prevents Coinbase from threatening to exit to renegotiate terms or build independent infrastructure, rendering Superchain membership nominal. OP holders are exposed to significant revenue dependence on a single counterparty with substantial downside risk, which we believe the market has not fully recognized.

1. Taking 71% of Revenue, Paying Only 2.5% 'Rent'

When Optimism initially signed the agreement with Base, the assumption was that no single chain would dominate the Superchain's economic ecosystem, preventing imbalanced revenue sharing. The fee share is calculated as the higher of '2.5% of the chain's revenue' or '15% of the chain's profit (revenue minus L1 Gas costs),' which seemed reasonable for a collaborative, diversified Rollup ecosystem.

But this assumption was wrong. In 2025, Base generated $74 million in chain revenue, accounting for over 71% of all OP chain sequencer fees, yet paid only 2.5% to the Optimism Collective. This means Coinbase captures 28 times the value it contributes. By October 2025, Base's TVL reached $5 billion (a 48% increase in six months), becoming the first Ethereum L2 to cross this threshold. Its dominance has only increased since.

Subsidy mechanisms exacerbate this imbalance. Although Base dominates revenue generation, the OP Mainnet, which shares 100% of its profits with the Collective, bears a disproportionate burden in ecosystem contributions. Essentially, the OP Mainnet is subsidizing the political cohesion of this alliance, while its largest member pays the smallest share.

Where do these fees go? According to Optimism's official documentation, sequencer revenue flows into the Optimism Collective's treasury. To date, this treasury has accumulated over $34 million from Superchain fees, but these funds have not been used or allocated to any specific projects.

The envisioned 'flywheel' (fees fund public goods → public goods strengthen the ecosystem → the ecosystem generates more fees) has not yet started turning. Current programs like RetroPGF and ecosystem grants are funded from the inflation of the OP token, not the ETH in the treasury. This is important because it undermines the core value proposition of joining the Superchain. Base contributes approximately $1.85 million annually to a treasury that does not deliver direct economic returns to the paying member chains.

Governance participation tells a similar story. Base published its 'Base Manifesto on Participating in Optimism Governance' in January 2024. Since then, there has been no public action: no proposals, no forum discussions, no visible governance participation. As the chain contributing over 70% of the Superchain's economic value, Base is conspicuously absent from the governance process it claims to participate in. Even Optimism's own governance forum rarely mentions Base. The so-called 'shared governance' value exists only on paper for both parties.

Therefore, the 'value' of Superchain membership remains entirely future-oriented—future interoperability, future governance influence, future network effects. For a publicly listed company accountable to shareholders, 'future value' is a hard sell when current costs are concrete and ongoing.

The ultimate question is: Does Coinbase have any economic incentive to maintain the status quo? And what happens when they decide they no longer need it?

2. The Ever-Possible 'Fork'

This is the legal reality behind all Superchain relationships: the OP Stack is an MIT-licensed public good. Anyone in the world can clone, fork, or deploy it for free, without any license.

So, what keeps chains like Base, Mode, Worldcoin, and Zora within the Superchain? According to Optimism's documentation, the answer is a series of 'soft commitments': participation rights in shared governance, shared upgrades and security, the ecosystem fund, and the legitimacy of the Superchain brand. Chains choose to join voluntarily, not by force.

We believe this distinction is crucial when assessing OP's risk.

Consider what Coinbase would lose by forking: participation in Optimism governance, the 'Superchain' brand, and channels for coordinating protocol upgrades.

Now consider what they would keep: 100% of the $5 billion TVL, all users, all applications deployed on Base, and over $74 million in annual sequencer revenue.

For 'soft commitments' to work, Base must need something from Optimism that it cannot build or buy itself. But evidence suggests Base is already building this independence. In December 2025, Base launched a direct cross-chain bridge to Solana, built using Coinbase's own infrastructure and based on Chainlink CCIP, rather than relying on the Superchain's interoperability solution. This indicates Base is not waiting for the Superchain's interoperability plan.

We are not asserting that Coinbase will fork tomorrow. We are pointing out that the MIT license itself is a fully realized 'exit option,' and Coinbase's recent actions show they are actively reducing their dependence on the value provided by the Superchain. A BASE token with an independent governance scope would complete this transition, turning those 'soft commitments' from meaningful constraints into purely ceremonial associations.

For OP holders, the question is simple: If the only reason keeping Base in the Superchain is the superficial appearance of an 'ecosystem alliance,' what happens when Coinbase decides the charade is no longer worth it?

3. Negotiations Have Already Begun

'Beginning to explore'—this is the standard phrasing used by every L2 roughly 6-12 months before officially launching a token.

In September 2025, Jesse Pollak announced at BaseCamp that Base was 'beginning to explore' issuing a native token. He cautiously added that there were 'no concrete plans at this time' and that Coinbase 'does not intend to announce a release date soon.' This is noteworthy because, until late 2024, Coinbase explicitly stated there were no plans for a Base token. This announcement came months after Kraken's Ink network revealed its INK token plans, signaling a changed competitive landscape for L2 tokenization.

We believe the phrasing is as important as the substance. Pollak described the token as a 'powerful lever for expanding governance, aligning developer incentives, and opening new design avenues.' These are not neutral terms. Protocol upgrades, fee parameters, ecosystem grants, sequencer selection—these are areas currently governed by the Superchain. A BASE token with governance rights for these decisions would overlap with Optimism's governance weight, and Coinbase would wield greater economic dominance.

To understand why a BASE token would fundamentally change the relationship, one must first understand the current Superchain governance mechanism.

The Optimism Collective uses a bicameral system:

· Token House (OP holders): Votes on protocol upgrades, grants, and governance proposals.

· Citizens' House (Badge holders): Votes on RetroPGF fund allocation.

Base's upgrade authority is controlled by a 2/2 multi-signature wallet, with signatories being Base and the Optimism Foundation—neither party can unilaterally upgrade Base's contracts. Once fully implemented, a Security Council will execute upgrades 'according to the instructions of Optimism governance.'

This structure gives Optimism shared control over Base, not unilateral control. The 2/2 multi-sig is a mutual check: Optimism cannot force an upgrade Base doesn't want, but Base cannot upgrade itself without Optimism's signature.

If Coinbase decides to follow the path of other L2 governance tokens like ARB and OP, structural conflict is inevitable. If BASE holders vote on a protocol upgrade, whose decision takes precedence—BASE governance or OP governance? If BASE has its own grants program, why would Base developers wait for RetroPGF? If BASE governance controls sequencer selection, what power remains for the 2/2 multi-sig?

Critically, Optimism governance cannot prevent Base from issuing a token whose governance scope overlaps with its own. The 'Law of Chains' sets standards for user protection and interoperability but does not restrict what a chain's governance can do with its own token. Coinbase could launch a BASE token with full governance over the Base protocol tomorrow, and Optimism's only recourse would be political pressure—the 'soft commitment' that is already losing its effectiveness.

Another interesting angle is the constraint of being a public company. This would be the first token generation event led by a publicly traded company. Traditional token launches and airdrops aim to maximize token value for private investors and founding teams. But Coinbase has a fiduciary duty to COIN shareholders. Any token distribution plan must demonstrate that it enhances Coinbase's corporate value.

This changes the game. Coinbase cannot airdrop tokens merely to maximize community goodwill. They need a structure that boosts COIN's stock price. One way is to use the BASE token as leverage to renegotiate lower Superchain revenue sharing, thereby increasing Base's retained earnings and ultimately improving Coinbase's financial statements.

4. Rebuttal Regarding 'Reputational Risk'

The strongest counterargument to our thesis is: Coinbase is a public company positioning itself as the 'compliant, cooperative' leader in crypto. Forking the OP Stack to save a few million dollars annually in revenue share seems petty and would damage its carefully cultivated brand image. This argument deserves serious thought.

The Superchain does provide real value. Its roadmap includes native cross-chain communication, and the total value locked (TVL) across all Ethereum L2s peaked at around $55.5 billion in December 2025. Base benefits from composability with the OP Mainnet, Unichain, and Worldchain. Abandoning this network effect comes at a cost.

Furthermore, there is the 118 million OP token grant. To solidify the 'long-term alliance,' the Optimism Foundation granted Base the opportunity to receive approximately 118 million OP tokens over six years. At the time of the agreement, this grant was worth about $175 million.

However, we believe this defense misunderstands the real threat. The rebuttal assumes a public, hard fork. The more likely path is a gentle renegotiation: Coinbase uses the leverage of the BASE token to secure more favorable terms within the Superchain. This negotiation might not even make news outside governance forums.

Consider the interoperability argument. Base has built its own bridge to Solana using CCIP, independent of Optimism's interoperability plan. They are not waiting for the Superchain's solution. They are building their own cross-chain infrastructure in parallel. When you're building your own solutions, the soft constraint of 'shared upgrades and security' becomes less important.

Consider the OP grant. Base's power to use these grants for voting or delegation is capped at 9% of the votable supply. This is not deep alignment but a minority stake with limited governance rights. Coinbase cannot control Optimism with 9%, but Optimism likewise cannot control Base with it. At the current price (~$0.32), the entire 118 million grant is worth approximately $38 million. If renegotiation causes the OP price to drop 30% due to reduced revenue expectations from Base, Coinbase's paper loss on this grant would be trivial compared to permanently canceling or drastically reducing the revenue share.

Reducing the 2.5% share of over $74 million in annualized revenue to 0.5% would permanently save Coinbase over $1.4 million per year. In contrast, a one-time impairment of the OP grant value by ~$10 million is a small price.

Institutional investors don't care about Superchain politics. They care about Base's TVL, transaction volume, and Coinbase's profitability. A renegotiated revenue share won't cause COIN stock price volatility. It would simply appear as a routine governance update on Optimism's forum and make Coinbase's L2 business margins slightly better.

5. A Single Revenue Source with an 'Exit Option'

We believe the market does not yet view OP as an asset with counterparty risk, but it should.

The token has fallen 93% from its all-time high of $4.84 to around $0.32, with a circulating market cap of approximately $620 million. The market has clearly revalued OP downward, but we believe it has not fully digested the structural risk embedded in the Superchain's economic model.

The market divergence illustrates the point. Base's TVL rose from $3.1 billion in January 2025 to a peak of over $5.6 billion in October. Base is winning, and OP holders are not. Consumer attention has almost entirely shifted to Base, and despite new partners joining, the OP Mainnet lags in ordinary user usage.

The Superchain looks like a decentralized collective. But economically, it relies heavily on a single counterparty that has strong incentives to renegotiate.

Look at the revenue concentration: Base contributes over 71% of all sequencer revenue to the Optimism Collective. The OP Mainnet's contribution proportion is high not because of its rapid growth but because it shares 100% of its profits, while Base shares only 2.5% or 15%.

Now consider the asymmetric payoff structure facing OP holders:

· If Base stays and grows: OP captures 2.5% of the benefit. Base keeps 97.5%.

· If Base renegotiates to ~0.5%: OP loses about 80% of its revenue from Base. The Superchain's largest economic contributor becomes insignificant.

· If Base exits completely: OP loses its economic engine overnight.

In all three scenarios, the upside is limited, while the downside could be unlimited. You hold a long position on a revenue stream where the largest payer holds all the cards, including an MIT-licensed exit option and an emerging token that could establish independent governance at any time.

The market seems to have digested that 'Base's growth does not effectively benefit OP holders.' But we believe it has not yet digested the exit risk—the possibility that Coinbase uses the BASE token as leverage to renegotiate terms or, worse, gradually severs ties with Superchain governance entirely.
