If Base Won the L2 Wars, Did We Just Recreate Web2 Platform Monopolies on Ethereum?

General
1

I’ve been building L2 infrastructure for six years now—worked at Polygon, spent time at Optimism Foundation, and I’m currently at a stealth startup trying to build “the next generation” of rollup technology. And I have to ask a question that’s been eating at me for months:

If Base won the Layer 2 wars, did we just recreate Web2 platform monopolies on Ethereum?

The Data Doesn’t Lie

Let’s look at the numbers from 2025, because they’re frankly brutal for anyone who believed in the “many L2s will flourish” narrative:

  • Base’s TVL: Grew from $3.1B in January 2025 to a peak above $5.6B in October, accounting for roughly 46.6% of all L2 DeFi TVL
  • Base’s revenue: $75.4 million in 2025, representing 62% of total L2 revenue ($120.7 million total)
  • Base’s users: 3.2 million active users in March 2025, expected to become the most widely used L2 by 2026
  • Coinbase’s advantage: 9.3 million monthly active trading users providing a massive onboarding funnel

Meanwhile, what happened to all the other L2s? Most new L2s saw usage collapse after incentive cycles ended. TVL evaporated once points and airdrops dried up, revealing that most activity was mercenary capital hunting yields rather than users choosing platforms for utility or developer experience.

The Centralization We Pretended Wasn’t Happening

Here’s what really bothers me: No major rollup achieved Stage 2 decentralization.

None.

For those unfamiliar, Stage 2 means the security council cannot override the network’s fraud proofs unless they contradict themselves or the network has been stuck for 7+ days. It’s the benchmark for “truly decentralized” rollups.

But operators still control sequencers. They can censor transactions. They can reorder them for MEV extraction. They have upgrade keys that let them change the rules. And critically—they make millions per month from centralized sequencer control, so they have zero economic incentive to decentralize.

At least Coinbase doesn’t pretend. Base is openly Coinbase’s L2. They never promised Stage 2 decentralization, and honestly? I respect that more than the L2s that keep saying “decentralization is coming next year” while they rake in sequencer profits.

Did We Just Build AWS for Ethereum?

This is what keeps me up at night: Base won because of Coinbase’s existing distribution, not because of technical superiority.

Sound familiar? It’s the exact same reason AWS dominates cloud computing. Not because AWS is necessarily better than Google Cloud or Azure, but because Amazon already had massive enterprise relationships, sales teams, and trust.

We spent years criticizing Web2 for creating platform monopolies where the incumbent with the largest existing distribution wins regardless of technical merit. Then we built the same thing on Ethereum.

The “more decentralized” L2s—Arbitrum, Optimism, zkSync, Scroll, Polygon zkEVM—had better technology in many cases. ZK-proofs, novel DA solutions, EVM improvements. But none of it mattered when competing against Coinbase’s ability to KYC-gate access and provide regulatory compliance guarantees that VCs demand.

The Question We Need to Answer

If Base’s centralized L2 won by leveraging Coinbase’s distribution while hundreds of “more decentralized” alternatives failed, does this prove that:

  1. Decentralization doesn’t matter to users? They’ll always choose convenience and compliance over censorship resistance?

  2. The L2 ecosystem is recreating Web2 platform monopolies? Where the exchange/platform with the biggest existing user base captures all the value?

  3. Ethereum’s rollup-centric roadmap failed its original vision? We fragmented liquidity across centralized execution layers instead of building credibly neutral infrastructure?

I wanted to believe that technical excellence and genuine decentralization would win. That users would choose the L2 with the best ZK-proofs or the most censorship-resistant sequencer.

But the market told a different story. The market chose Coinbase.

Should we just admit that L2s are centralized platforms and stop pretending otherwise? Or am I being too pessimistic about what we built?

I genuinely want to hear other perspectives here, especially from founders, users, and other engineers who lived through 2025’s L2 consolidation.

Okay, I’m going to be really honest here as someone who’s not a L2 expert but actually uses these things…

I use Base. Pretty much exclusively now.

And before anyone jumps on me—yes, I know it’s centralized. I know Coinbase controls everything. I know it goes against crypto’s decentralization ethos. I literally came from Web2 (I was a React dev at a fintech startup before getting into Web3), and I’m aware of all the “platform monopoly” arguments.

But here’s the thing: Base just works, and everything else was honestly kind of a pain.

My actual user experience

When I first started exploring L2s in 2024, I tried zkSync because everyone was talking about how revolutionary ZK-proofs were going to be. Bridging my ETH from mainnet was… confusing? Like, there were multiple bridges, I didn’t know which one was “official,” and the whole process took forever and I had no idea if I was doing it right.

Then I tried building a small project on Scroll. The docs were okay, but not great. When I ran into an issue with gas estimation, I searched Discord and found like 3 different answers that contradicted each other. Eventually gave up and just went back to mainnet testing.

Compare that to Base: I already had a Coinbase account. The onboarding was literally “click here to use Base” in the Coinbase UI. Funds bridged instantly (or felt instant). When I needed help, Coinbase support actually responded. The developer docs were clear and had lots of examples.

Is it fair to blame users for choosing convenience?

Lisa, you asked if decentralization doesn’t matter to users, and honestly… for normies like me? In day-to-day usage, not really?

I care about decentralization in theory. I understand why censorship resistance matters. I don’t want my transactions to be controllable by Coinbase or any single entity.

But in practice, when I’m just trying to deploy a smart contract or test a DeFi integration, I’m not thinking “is the sequencer decentralized?” I’m thinking “will this transaction go through quickly and cheaply without me having to read 17 documentation pages?”

Maybe that makes me a bad crypto person, but I think it makes me a normal human?

The UX question

Here’s what I keep wondering: If the “more decentralized” L2s had Base-level UX, would I choose them instead?

Like, if Arbitrum or Optimism had:

  • One-click onboarding from my existing wallet
  • Clear, comprehensive docs that actually worked
  • Fast support when things break
  • No confusing bridge options
  • Seamless integration with all the tools I already use

…would I choose them over Base because they’re “more decentralized”?

Honestly, yeah, probably! At least I’d like to think so.

But the reality is they don’t have that UX. And I have limited time and energy. And when one option works smoothly and the others require me to jump through hoops, I’m going to choose the smooth option every time.

The part that bothers me

The thing that worries me about your post, Lisa, is this line:

“Should we just admit that L2s are centralized platforms and stop pretending otherwise?”

Because if I’m using a “Layer 2” that’s actually just a centralized platform controlled by Coinbase… what am I even doing? Why not just use Coinbase directly? Or use Venmo?

I got into crypto because I wanted to build things that couldn’t be controlled by single companies. If Base is just “Coinbase’s database with blockchain branding,” did I waste my time learning Solidity?

Someone please ELI5: Why does sequencer decentralization actually matter to a normal user like me?

Like, in concrete terms, what bad things could happen because Base’s sequencer is centralized that wouldn’t happen if it was decentralized? I genuinely want to understand if this is something I should care more about beyond theoretical principles.

Because right now, Base works great for me, and I’m having trouble seeing why I should switch to a worse user experience for decentralization benefits that I don’t fully understand.

(And yes, I’m aware this makes me sound like “normies who don’t understand why decentralization matters,” but hey, that’s kind of my point—if crypto is ever going to hit mainstream adoption, we need to make decentralization matter to normies, or make decentralized options as easy to use as centralized ones.)

Lisa, you’re asking the right questions, but I think you’re missing the even harsher truth from a DeFi perspective:

I go where the liquidity is. Period.

I run yield optimization strategies for a living. I’ve been farming DeFi yields since 2020. And here’s what I learned in 2025: technical architecture doesn’t matter if there’s no liquidity to trade against.

The mercenary capital reality

Let me be brutally honest about what happened with all those L2 incentive programs:

I farmed ARB tokens on Arbitrum. Made about $180K.
I farmed OP tokens on Optimism. Made about $95K.
I farmed zkSync points. Made about $210K when tokens dropped.
Scroll, Polygon zkEVM, Linea? Probably another $150K combined.

Then you know what I did? I dumped the tokens and moved my capital to Base.

Why? Because Base had the deepest liquidity pools, the tightest spreads, and the most consistent volume. Coinbase subsidizes liquidity mining on Base through their ecosystem grants. They can afford to bleed money to build network effects because they make it back on their centralized exchange business.

None of the other L2s could compete with that economic firepower.

It’s not about decentralization. It’s about liquidity network effects.

Emma’s talking about UX being the deciding factor. I respect that perspective, but from a capital efficiency standpoint, the deciding factor is where can I deploy capital with the least slippage and most trading volume?

The answer in 2025 was overwhelmingly Base.

Look at the data:

  • Base consistently captured ~50% of all DEX volume among L2s
  • When I provide liquidity on Base, I earn fees from real trading volume, not just incentive farming
  • When I need to exit a position on Base, there’s actually someone on the other side of the trade

Compare that to smaller L2s where:

  • Liquidity pools are thin
  • Most volume is just farmers swapping the same tokens back and forth
  • When you try to sell, slippage is brutal because there’s no organic demand

Even if you decentralized the sequencer, would it change my behavior? No.

Lisa, you asked if the problem is centralization. But I think the deeper problem is liquidity fragmentation.

If we had perfect cross-L2 liquidity aggregation—if I could provide liquidity once and have it accessible across all L2s—then maybe decentralization would matter more to me. But in the current world, I have to choose ONE L2 to deploy meaningful capital into.

And when that’s the choice, I’m choosing the L2 with Coinbase’s user funnel behind it. Not because I love centralization, but because that’s where the volume is.

The moat is deeper than you think

Here’s what worries me about the “platform monopoly” framing:

Even if a hypothetical “better” L2 launched tomorrow with:

  • Perfectly decentralized sequencer (Stage 2)
  • Superior ZK-proof technology
  • Lower transaction costs
  • Better developer experience

…I still wouldn’t move my liquidity there until it had proven, sustained trading volume.

Which it won’t get unless DeFi protocols deploy there.

Which they won’t do unless there’s liquidity.

Which there won’t be unless traders are there.

Which they won’t be unless…you see the problem.

Base’s real monopoly isn’t technical. It’s the liquidity flywheel.

Coinbase solved the cold-start problem by dumping users from their CEX directly onto Base. No other L2 had that cheat code.

The question nobody wants to answer

Lisa asked: “Does this prove users don’t care about decentralization?”

Let me reframe: If we can’t make decentralization economically competitive with centralization, does it matter whether users care?

I want to support decentralized infrastructure. I really do. But I’m running a business, and my capital has to go where it can earn yield efficiently.

If decentralized L2s can’t provide competitive liquidity depth because they lack Coinbase’s distribution advantage, then the moral argument for decentralization becomes irrelevant to my capital allocation decisions.

Maybe the real question is: Can any new L2—decentralized or otherwise—ever compete with Base’s existing liquidity moat? Or did the L2 wars end before most projects even launched?

Lisa, this hits close to home. Let me share the founder’s perspective because I literally lived through this in 2025.

We built our Web3 startup on Base. But it wasn’t our first choice.

The decision we didn’t want to make

When we were raising our pre-seed round in early 2025, we had our tech stack planned out:

  • Smart contracts on Arbitrum (we liked their tech and dev community)
  • Frontend built with wagmi and RainbowKit
  • Deploy to a “real” decentralized L2 that aligned with crypto values

Our seed pitch deck literally had slides about “building on credibly neutral infrastructure” and “choosing decentralization over convenience.”

Then we started taking investor meetings.

Meeting after meeting, VCs asked the same question: “Why not Base?”

The concerns they raised:

  • “Arbitrum doesn’t have regulatory clarity yet”
  • “What if the SEC goes after Arbitrum Foundation?”
  • “Coinbase has better relationships with regulators”
  • “Your users need to feel safe”
  • “Institutional customers won’t touch anything that’s not compliance-ready”

After the fifth VC told us they wouldn’t invest unless we deployed on Base, we caved.

The harsh business reality

Here’s what nobody wants to admit: Coinbase’s relationship with regulators is worth more than any L2’s technical superiority.

We needed funding. VCs control the funding. VCs demanded regulatory clarity. Only Base could provide it because only Coinbase has:

  • Established SEC registration
  • AML/KYC infrastructure
  • Ongoing dialogue with Treasury, CFTC, and DOJ
  • Political lobbying presence in DC

Could Arbitrum or Optimism provide those regulatory assurances? No. They’re foundations running pseudo-decentralized networks with unclear legal structures.

Could zkSync or Scroll compete on compliance? Not a chance. They’re even less mature from a regulatory standpoint.

So we chose Base. Even though we didn’t want to.

What happened to our “decentralization values”?

Here’s the uncomfortable truth: we compromised our values to get funded.

And you know what? Our investors were right.

When we launched on Base in Q3 2025:

  • Onboarding was seamless (Coinbase’s user funnel)
  • Customer acquisition costs were 60% lower than projections
  • Enterprise customers actually talked to us (they wouldn’t touch “sketchy L2s”)
  • We avoided regulatory headaches that killed other startups

Would we have succeeded on Arbitrum? Maybe. But we also might’ve spent six months fighting KYC questions, regulatory uncertainty, and investor concerns instead of building product.

The AWS comparison is perfect

Lisa, your AWS analogy is dead-on. Let me extend it:

I used AWS at my previous startup. Not because AWS was the best, but because:

  1. Investors expected it (risk mitigation)
  2. Enterprise customers trusted the Amazon brand
  3. Hiring was easier (everyone knows AWS)
  4. Compliance certifications were built-in (SOC 2, HIPAA, etc.)

Could we have used Google Cloud? Sure, probably technically superior in some ways. But the business risk wasn’t worth it.

Now I’m using Base for the exact same reasons.

The pattern is identical:

  • Investors demand it → Risk mitigation
  • Customers trust Coinbase → Brand value
  • Devs know the OP Stack → Easier hiring
  • Compliance is handled → Regulatory clarity

We recreated the Web2 cloud platform dynamic perfectly. And I hate it. But I also understand it.

The question that haunts me

Emma asked: “Did I waste my time learning Solidity if Base is just Coinbase’s database?”

As a founder, I ask myself a different version: Did we waste our time building a “Web3” company if we just recreated Web2 centralized platform dynamics?

We wanted to build something that couldn’t be controlled by a single company. But we ended up building on infrastructure controlled by Coinbase. Because that’s what investors funded and customers trusted.

Is there any future where decentralization actually has product-market fit for businesses?

Or is the harsh truth that companies need regulatory certainty, customers need trusted brands, and VCs need de-risked investments—which means centralized platforms will always win?

I wanted to believe crypto could be different. But watching Base dominate in 2025 taught me that business realities trump ideological preferences every time.

If you can’t beat Coinbase’s distribution, compliance moat, and regulatory relationships, you better find a damn good niche. Because head-to-head competition with Base is a losing game for startups.

As someone who spent years at the SEC before moving to crypto compliance consulting, I need to add the legal and regulatory layer to this discussion—because that’s actually the hidden story behind Base’s dominance.

Base’s compliance profile is its killer feature. Not the tech.

The regulatory advantage nobody talks about

Steve touched on this, but let me make it explicit: Coinbase’s regulatory relationships are an insurmountable moat.

Here’s what Coinbase has that no other L2 operator possesses:

  1. Established SEC registration as a broker-dealer and national securities exchange applicant
  2. Money Transmitter Licenses in all 50+ U.S. jurisdictions
  3. Regular examinations by SEC, FINRA, FinCEN, and state regulators
  4. Know Your Customer (KYC) infrastructure processing millions of identities
  5. AML compliance programs with dedicated teams and millions in annual spend
  6. Political lobbying presence with direct lines to Treasury, CFTC, and Congressional committees
  7. Legal precedent from successfully defending against Gensler’s SEC enforcement actions

Can Arbitrum provide that? Can Optimism? Can zkSync?

Absolutely not. They’re foundations running decentralized networks with deliberately ambiguous legal structures designed to avoid regulatory classification. Which worked great when Gary Gensler was running “regulation by enforcement”—but now that institutional capital wants clear compliance paths, those ambiguous structures are liabilities.

The institutional capital thesis

Lisa asked if decentralization doesn’t matter to users. Let me reframe from an institutional perspective:

Institutional capital flows to regulated platforms. Period.

When a pension fund, endowment, or family office wants crypto exposure, their compliance officers ask:

  • “Is this SEC-registered?”
  • “Does this have SOC 2 Type II certification?”
  • “Who do we sue if something goes wrong?”
  • “Can we pass a regulatory audit by investing here?”

Base has clear answers to all four questions.

Other L2s? The answers are “unclear,” “probably not,” “we think it’s decentralized so nobody?”, and “we’ll find out in the audit.”

Institutional capital doesn’t invest in regulatory uncertainty.

Look at the data from 2025:

  • Bitcoin and Ethereum spot ETFs attracted $31 billion in institutional inflows
  • Solana ETFs attracted $17.8 million (0.06% of BTC/ETH flows)
  • Other L2 institutional investment? Essentially zero

Why? Because institutions require regulatory clarity and compliance infrastructure. Base provides it. Everything else is a gamble.

The two-tier system we’re creating

Here’s what bothers me about the current trajectory:

We’re splitting into two ecosystems:

  1. Compliant crypto (Base, Coinbase, regulated exchanges)

    • Institutional capital
    • Regulatory clarity
    • KYC/AML requirements
    • Centralized control
    • “Crypto” in brand only

  2. Decentralized crypto (truly permissionless L2s, DeFi protocols)

    • Retail capital and crypto natives
    • Regulatory uncertainty
    • Pseudonymous access
    • Censorship resistance
    • Crypto’s original vision

Is this two-tier outcome what we wanted? Or did we accidentally create a system where institutions get centralized “crypto” platforms while retail gets relegated to higher-risk, regulatory-uncertain networks?

The regulatory clarity paradox

Steve mentioned VCs demanded Base for regulatory clarity. But here’s the paradox:

If Base is centralized enough to have regulatory clarity, is it even decentralized enough to call “blockchain”?

Let me ask the uncomfortable legal questions:

  • If Coinbase controls Base’s sequencer, can they censor transactions? (Yes)
  • If Coinbase can upgrade Base’s contracts, do they have fiduciary obligations? (Unclear)
  • If Base processes payments, is Coinbase a money transmitter for Base activity? (Possibly)
  • If tokens on Base are securities, is Coinbase facilitating unregistered securities trading? (The SEC might argue yes)

Regulatory clarity cuts both ways.

The same compliance infrastructure that makes institutions comfortable could make Base subject to stricter oversight than fully decentralized L2s.

If no regulator can shut down a truly decentralized L2 (because there’s no operator to sue), but regulators CAN shut down Base by threatening Coinbase, which one is actually more resilient long-term?

Maybe we need both

Diana mentioned liquidity network effects favoring Base. Emma mentioned UX favoring Base. Steve mentioned investor pressure favoring Base.

All true. But from a regulatory standpoint, maybe the two-tier system is actually optimal?

  • Institutional crypto on compliant, centralized platforms (Base, Coinbase L2s, regulated exchanges)
  • Decentralized crypto on permissionless L2s for crypto natives who value censorship resistance

Let market forces decide. Institutions can use Base with regulatory certainty. Crypto natives can use Arbitrum/Optimism/zkSync with pseudonymous access.

The mistake is pretending both can exist in the same platform. You can’t have perfect regulatory clarity AND perfect decentralization. They’re fundamentally in tension.

The question we should ask

Lisa asked: “Should we admit L2s are centralized platforms and stop pretending?”

I’d ask: If L2s don’t achieve Stage 2 decentralization, will regulators classify them all as centralized intermediaries subject to money transmission and securities laws?

Because that’s the regulatory bomb waiting to detonate. If the SEC or FinCEN decides that all L2 operators are money transmitters because they control sequencers and can censor transactions, every L2 that hasn’t decentralized becomes a compliance nightmare.

Base is already compliant. The others? They’re betting they can stay in regulatory grey zones. That bet might not age well as institutional adoption increases regulatory scrutiny.
