Recently, I noticed something quite interesting happening in the Layer 2 ecosystem. On February 18th, a very carefully announced statement caused the market to react drastically. The OP token dropped 28% within 48 hours, with trading volume surging 157%. To date, the price has fallen 89.8% year-over-year, trading at just $0.12, far from its peak of $4.85 in March 2024.

It turns out, the largest chain ever built with OP Stack—let’s call it the "leading chain"—announced it will leave the Superchain. They will fully integrate the source code, accelerate development cycles from 3 to 6 major updates per year, and run their own security committee. The technical reasons sound reasonable, but there’s a deeper business logic at play.

I used to think the Superchain was a true alliance with real value for all members. The reality? It’s a classic open-source story repeating itself. Optimism released OP Stack under the most permissive MIT license—anyone can take, modify, or fork it without paying anything. The logic is simple: lower adoption barriers to zero, let anyone build chains permissionlessly. This strategy has been incredibly successful. By mid-2025, OP Stack handled 69.9% of all L2 fees, with 34 chains live.

But here’s the problem. The Superchain offers interoperability as an exchange—pay 2.5% of revenue or 15% of net profit, and you gain access to an integrated network with liquidity and users moving seamlessly across chains. Sounds good on paper. However, interoperability was never actually launched. Planned for early 2025, but it never happened. So members pay a "tax" for a product that’s still theoretical.

Meanwhile, the leading chain continues to grow rapidly. By January 2026, they accounted for 96.5% of all gas fees flowing into the Optimism Collective—almost all of them. Their transactions are four times larger than OP Mainnet, DEX volume 144 times larger, gas revenue 80 times higher. Of the 14,000 ETH the Collective has ever received in total, the leading chain contributed 8,387 ETH. Their monthly contributions keep approaching 100%.

This raises the most fundamental question—business profit interests. When the biggest partner grows this much, they start asking: What do I get? They have their own users, their own token roadmap, and strong reasons to fully control their infrastructure. There’s no mechanism in the protocol binding them. The promise of interoperability isn’t enough. So they leave.

Arbitrum understood this dynamic from the start. They chose the Business Source License for their Orbit chain, where revenue sharing is locked in a contract, not voluntary. Optimism made a different choice—and that’s perfect for setting standards, but bad for capturing value from that success.

Now let’s broaden the perspective. Throughout 2024, more than 50 L2s competed. By the end of 2025? Base, Arbitrum, and Optimism dominated nearly 90% of L2 transactions. Small rollup activity dropped 61% since June. The Dencun upgrade caused fees to fall 90%, squeezing industry profit margins. Only one L2 was profitable in 2025.

The chains that survive aren’t necessarily the most technically advanced. They are the ones with structures to retain users. Chains backed by exchange leverage distribute from their existing 100 million users. Native DeFi chains maintain their position through liquidity that can’t be moved. Technology is copyable. OP Stack proves that. What’s not copyable are relationships with millions of users or billions of dollars in open positions.

Optimism made the right decision to release OP Stack with an open license. This brought the widest adoption, making them the standard infrastructure for scaling Ethereum. Without this, the leading chains might not exist. But the decision that made everything possible also enables departure without cost. Business profit interests ultimately outweigh alliance commitments.

For Optimism, there’s still the OP Mainnet with $1.5 billion TVL. A few weeks ago, a major yield farming protocol announced it would move to OP Mainnet with 70,000 active users and $160 million TVL. The Collective just approved a buyback plan, using 50% of revenue to repurchase OP each month. But the annual contribution from that new partnership is only $13 million, while the leading chain alone generated $55 million in profit in 2025.

The revenue base for the buyback plan has already disappeared. Investor unlocks continue at $32 million per month. Shifting to business services might be the right path. OP Labs has $175 million in funding, top-tier engineering talent, and real institutional demand for managed OP Stack implementation. This could become a profitable services business. But it’s completely different from a network that generates protocol revenue from partners.

The $0.12 token price reflects the market’s valuation of all this. Optimism wins the standards war, but its standards lack mechanisms to capture the value they create. It’s a harsh lesson in blockchain open-source economics. Business profit interests ultimately always override alliance ideology.
