OP Labs
OP Labs builds the open-source OP Stack code that powers Ethereum's Optimism L2 network and Superchain.
On the record
Checkpoint: Karst hard fork mainnet activation, pending governance approval
The call
OP Labs sold access to code it could not lock down, and its biggest tenant walked out the door with the source in hand.
OP Labs created free, open-source code that other companies use to build their own blockchains, then charged those companies a percentage of their earnings. Base, owned by Coinbase, used that code to build itself, then decided to stop paying OP Labs and just run independently, which took away most of OP Labs' revenue overnight. OP Labs is trying to switch to selling managed services and support contracts instead, but it has not yet shown it can make real money this way or keep customers locked in long-term. The question is whether other big blockchain networks do the same fork-and-leave move in the next six months, or whether companies like Toss in Korea and Mitsui in Japan will actually sign up to pay for OP Labs' support services.
Why
01
AI pressure: AI coding assistants (Cursor, Devin, Copilot-style agents). AI tools cut the cost of forking and running MIT-licensed OP Stack code, making Base-style exits cheaper for any other chain. Could AI do the core job? Only partly.
02
Bigger players: Base (Coinbase's L2). Base forked OP Stack, kept the code, and left the Superchain in Feb 2026, taking an estimated 70-96.5% of sequencer revenue with it. Could a giant copy it? Yes, easily.
03
What protects it. Remaining Superchain members (Unichain, Ink, World Chain, Soneium) still pay in, and OP Labs still controls the core dev roadmap and Karst upgrade.
What would change this call
Unichain, Ink, World Chain, or Soneium exits OP Stack for an independent codebase within 6 months. Would show Base's exit was the start of a pattern, not an isolated event.
OP Enterprise lands 2-3 paying institutional customers (e.g. Toss, Bitpanda, Mitsui) at real recurring ACV. Would show OP Labs can replace lost sequencer revenue with managed services.
OP token price and Superchain sequencer revenue trend over next two quarters. Would show whether the financial hole from Base's exit is stabilizing or widening.

Key numbers
- Base cut Superchain payments to ~$1.4M in Q1 2026, capped at 2.5%
- OP Labs cut staff from ~100 to ~80 (20%)
- OP token fell to $0.093-$0.13, a multi-year low
Named risks
- Base's Feb 2026 exit removed majority of Superchain sequencer revenue.
- Other top Superchain members (Unichain, Ink, World Chain) could also leave OP Stack.
- OP token trading near multi-year lows (~$0.093, July 2026) signals market distrust.
- OP Enterprise managed-services pivot revenue unproven at scale.
- MIT-licensed OP Stack code remains freely forkable by any future tenant.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Base (Coinbase) | losing to | Took est. 70-96.5% of Superchain sequencer revenue then forked its own stack, Feb 18, 2026 |
| Offchain Labs (Arbitrum) | contesting | Closest direct L2/rollup-stack rival, competing on throughput narratives as of March 2026 |
| Polygon Labs | contesting | Competing chain-infrastructure and enterprise institutional deployment provider |
| ZKsync (Matter Labs) | contesting | Listed competitor ZK-rollup stack in company profile data, 2026 |
Questions people ask
- Is OP Labs profitable in 2026?
- No public profit figures exist. CEO Jing Wang said in March 2026 OP Labs is 'well capitalized with years of runway,' but the company cut 20% of staff that same month after Base's February 2026 exit stripped most Superchain sequencer revenue.
- Did OP Labs have layoffs?
- Yes. On March 12, 2026, OP Labs cut roughly 20% of staff, going from about 98-102 employees to roughly 78-82, a move analysts linked to anticipated revenue loss from Base's February 2026 departure from the OP Stack.
- Could AI replace OP Labs?
- Unlikely to replace it outright. OP Labs does protocol engineering, security governance, and enterprise infra services, not a thin AI-replaceable wrapper. It was hiring an AI Lead Engineer as of mid-2026 to build internal AI tooling, mainly affecting engineering efficiency, not the core product.
- Who is OP Labs' biggest competitor?
- Base, Coinbase's L2, is the most damaging: it generated an estimated 70-96.5% of Superchain sequencer revenue before announcing on February 18, 2026 it would fork OP Stack and build its own independent codebase. Arbitrum (Offchain Labs) and Polygon Labs also compete directly.
- Who owns OP Labs?
- OP Labs is privately held, backed by venture investors including a16z and Paradigm, which led a $150M Series B in March 2022 valuing the company near $1.65B. It is distinct from the nonprofit Optimism Foundation, which governs the OP token and Collective.
- Why did Base leave Optimism's OP Stack?
- Base, which generated an estimated 70-96.5% of Superchain sequencer revenue (about $74M in 2025) but paid only a capped 2.5% share (~$1.4M in Q1 2026) to the Collective, announced on February 18, 2026 it would build its own independent codebase instead.
