Enterprise Rollups: The New Era of Ethereum Scaling
When Robinhood announced it was building an Ethereum Layer 2 using Arbitrum's technology in June 2025, it signaled something far more significant than another exchange adding blockchain features. It marked the moment when "enterprise rollups"—Layer 2 networks built or adopted by major corporations—became the defining trend reshaping Ethereum's scaling narrative. But as Kraken, Uniswap, and Sony follow suit, a critical question emerges: are we witnessing the democratization of blockchain infrastructure, or the beginning of corporate capture?
The numbers tell a compelling story. Layer 2 Total Value Locked has surged from under $4 billion in 2023 to roughly $47 billion by late 2025. Transaction costs have plummeted below $0.01, and average throughput now exceeds 5,600 transactions per second. Yet beneath these impressive metrics lies an uncomfortable truth: the Layer 2 landscape has bifurcated into a handful of winners and a graveyard of ghost chains.
The Great L2 Consolidation
2025 exposed the brutal reality of Layer 2 economics. While Base, Arbitrum, and Optimism collectively process nearly 90% of all L2 transactions, most new launches have become ghost towns shortly after their token generation events. The pattern is distressingly consistent: incentive-driven activity ahead of airdrops, followed by rapid collapse as liquidity and users migrate elsewhere.
This concentration has profound implications. The Optimism Superchain now accounts for 55.9% of all L2 transactions, with 34 OP Chains securing billions in value. Base alone represents 46.6% of all L2 DeFi TVL, extending what has been essentially uninterrupted exponential growth since launch. Arbitrum maintains roughly 31% of L2 DeFi TVL, though its position increasingly depends on institutional adoption rather than retail speculation.
The lesson is clear: distribution and strategic partnerships, not technical differentiation, are becoming the primary drivers of L2 success.
The Four Horsemen of Enterprise Rollups
Robinhood: From Brokerage to Blockchain
When Robinhood unveiled its Arbitrum-based Layer 2 in June 2025, it came with an audacious proposition: tokenize 2,000+ stocks and bypass traditional market hours entirely. The initiative, dubbed "Stock Tokens," allows European customers to trade U.S. stocks and ETFs on-chain with zero commission fees, complete with dividend payments within the brokerage app.
What makes Robinhood's approach notable is scope. The tokenized offerings include not just public equities but privately traded giants like OpenAI and SpaceX—assets previously inaccessible to retail investors. CEO Vlad Tenev positioned it as "showing what's possible when crypto meets transparency, access, and innovation."
The Arbitrum Foundation has since claimed that institutional finance moved from trials to production on its stack, citing Robinhood's tokenized equities rollout alongside RWA deployments with Franklin Templeton, WisdomTree, BlackRock, and Spiko.
Kraken: The Ink Revolution
Crypto exchange Kraken launched its Layer 2 "Ink" ahead of schedule in December 2024, built on Optimism's OP Stack and integrated into the broader Superchain ecosystem. The network received 25 million OP tokens in grants from the Optimism Foundation—a substantial vote of confidence.
Ink's strategy differs from Robinhood's equity focus. The Ink Foundation announced plans to launch and airdrop an INK token, directly challenging Coinbase's Base for exchange-affiliated L2 dominance. The ecosystem already features Tydro, a white-label instance of Aave v3 that supports the INK token, positioning Ink as a full-fledged DeFi destination rather than a mere extension of exchange services.
With Kraken considering an IPO as early as Q1 2026, Ink represents a strategic asset that could significantly enhance the company's valuation by demonstrating blockchain infrastructure capabilities.
Uniswap: DeFi's Native Chain
Uniswap's Unichain officially launched on February 11, 2025, after four months of testnet activity that saw 95 million transactions and 14.7 million smart contracts deployed. Unlike corporate entrants, Unichain represents DeFi's first attempt to own its own execution environment.
The technical specifications are impressive: one-second block times at launch, with 250-millisecond "sub-blocks" promised soon. Transaction costs run approximately 95% lower than Ethereum L1. But Unichain's most significant innovation may be philosophical—it's the first L2 to build blocks inside a trusted execution environment (TEE), bringing unprecedented transparency to block building while mitigating extractive MEV.
Crucially, Unichain transforms UNI from a governance token into a utility token. Holders can stake to validate transactions and earn sequencer fees, creating economic alignment between the protocol and its community. Nearly 100 major crypto products are already building on Unichain, including Circle, Coinbase, Lido, and Morpho.
Sony: Entertainment Meets Web3
Sony's Soneium, launched January 14, 2025, represents the most ambitious corporate Web3 bet outside the financial sector. Built with Startale Labs, Soneium positions itself as a "versatile general-purpose blockchain platform" for gaming, finance, and entertainment applications.
The traction has been substantial: over 500 million transactions, 5.4 million active wallets, and more than 250 live decentralized applications. Sony doubled down with an additional $13 million investment in Startale in January 2026, specifically to scale "on-chain entertainment infrastructure."
Soneium's killer app may be IP integration. The platform supports flagship properties including Solo Leveling, Seven Deadly Sins, Ghost in the Shell, and Sony's robotic companion aibo. With Sony owning some of the world's most valuable intellectual property—God of War, Spiderman—Soneium allows the entertainment giant to control how that IP is used in the digital world.
The "Soneium For All" incubator, launched with funding up to $100,000 per project, targets MVP-ready gaming and consumer applications, while Sony Bank plans to issue a dollar-pegged stablecoin for use within Sony's gaming, anime, and content ecosystems by fiscal year 2026.
The Architecture of Enterprise Adoption
The enterprise rollup trend reveals a clear preference for established, battle-tested infrastructure. All four major enterprise entrants chose either OP Stack (Kraken, Sony, Uniswap) or Arbitrum (Robinhood) rather than building from scratch or using newer alternatives.
This standardization creates powerful network effects. The Superchain model means that Ink, Soneium, and Unichain can interoperate through native cross-chain messaging, sharing security and governance. Optimism's upcoming Interop Layer, planned for early 2026, will enable single-block, cross-chain message passing among Superchain L2s—a technical capability that could make chain-hopping as seamless as tab-switching.
For enterprises, the calculus is straightforward: proven security, regulatory clarity, and ecosystem integration outweigh the theoretical benefits of technical differentiation.
Privacy, Compliance, and the ZK Alternative
While OP Stack and Arbitrum dominate enterprise adoption, ZK rollups are carving out a distinct niche. ZKsync's Prividium framework sets benchmarks for enterprise-grade privacy, combining high throughput with robust confidentiality. The platform now offers Managed Services to help institutions launch and operate dedicated ZK Stack rollups with enterprise-grade reliability.
ZK rollups (Starknet, zkSync) now achieve 15,000+ TPS at $0.0001 per transaction, enabling institutional-grade scalability and compliance for tokenized assets. For high-value transactions, institutional use cases, and privacy-sensitive applications, ZK-based solutions increasingly represent the technology of choice.
The 2026 Outlook: Consolidation Accelerates
Projections for 2026 suggest continued concentration. Analysts predict that by Q3 2026, Layer 2 TVL will exceed Ethereum L1 DeFi TVL, reaching $150 billion versus $130 billion on mainnet. Galaxy Digital estimates that Layer 2 solutions could process 80% of Ethereum transactions by 2028, up from approximately 35% in early 2025.
Institutional adoption continues accelerating, driven by regulatory clarity from the GENIUS Act and MiCA, alongside L2 innovations like ZK rollups and modular blockchains. According to recent surveys, 76% of global investors plan increased crypto allocations by 2026, prioritizing L2s with interoperability, governance frameworks, and traditional finance integration.
The market cap of tokenized public-market RWAs has already tripled to $16.7 billion as institutions adopted blockchains for issuance and distribution. BlackRock's BUIDL has emerged as the reserve asset underpinning a new class of on-chain cash products, validating the enterprise rollup thesis.
What This Means for Ethereum
The enterprise rollup wave fundamentally changes Ethereum's strategic position. Public blockchains, especially Ethereum, are transitioning from experimental sandboxes to credible institutional infrastructure. Ethereum's established financial primitives and strong security model make it the preferred settlement layer—not for retail speculation, but for institutional capital markets.
Yet this transition carries risks. As major corporations build proprietary L2s, they gain significant control over user experience, fee structures, and data access. The permissionless ethos of early crypto may increasingly conflict with enterprise requirements for compliance, KYC, and regulatory oversight.
The coming years will determine whether enterprise rollups represent blockchain's path to mainstream adoption or a Faustian bargain that trades decentralization for distribution.
The Bottom Line
The enterprise rollup wars have redefined what success looks like in the Layer 2 landscape. Technical superiority matters less than distribution channels, brand trust, and regulatory positioning. Robinhood brings 23 million retail traders. Kraken brings institutional credibility and exchange liquidity. Uniswap brings DeFi's largest protocol ecosystem. Sony brings entertainment IP and 100 million PlayStation users.
This is not the permissionless revolution early crypto advocates imagined—but it may be the one that actually scales. For developers, builders, and investors navigating 2026, the message is clear: the era of "launch a chain and they will come" is over. The era of enterprise rollups has begun.
