Robinhood launched its dedicated Layer 2 blockchain on July 1, built on Arbitrum's technology stack and settling to Ethereum with ETH as the gas token. The launch followed Robinhood's 2025 deployment of Classic Stock Tokens on Arbitrum One for European customers, a launch-and-migrate model that validated usage patterns before the company committed to a dedicated chain. Within two weeks of going live, the chain accumulated $600 million in total value secured, generated over $800,000 in revenue (a roughly $23 million annualized run rate), and briefly ranked third among all crypto networks by 24-hour DEX trading volume, with a peak of $808 million. That peak figure has not been sustained, but the scale of early activity reflects the depth of Robinhood's existing user base: 28 million customers across 38 countries, managing $307 billion in assets under management.

The chain operates with 100-millisecond block times, enabled by configurable block timing and preconfirmations baked into Arbitrum's infrastructure. It is one of more than 30 chains operating under the Arbitrum Expansion Program (AEP), a licensing framework that routes a portion of protocol revenue back to the ArbitrumDAO treasury. Under the model, 8 percent of net protocol revenue flows to the DAO and 2 percent goes to the Arbitrum Developer Guild. According to the ArbitrumDAO Forum, the Robinhood Chain launch demonstrates how the AEP can convert infrastructure adoption directly into protocol revenue at institutional scale.

"We're bringing the best of traditional finance and DeFi together, and in doing so, expanding financial ownership to every corner of the globe," said Johann Kerbrat, SVP and GM of Crypto and International at Robinhood, in a statement accompanying the launch.

The headline product on the new chain is a set of tokenized stock tokens covering more than 200 US equities and ETFs, available through Robinhood Wallet in over 120 countries, excluding the United States, Canada, United Kingdom, Switzerland, and UAE. The tokens are structured as debt securities rather than direct share ownership, which carries a range of legal implications for holders: beyond the absence of standard shareholder rights, the structure may also affect dividend treatment, tax classification, and insolvency priority.

That distinction matters for users outside those excluded markets who may be drawn in by exposure to US equities but should understand the legal structure before participating. India, for example, has a 30 percent flat tax on crypto gains and a 1 percent transaction levy; the Securities and Exchange Board of India has not formally classified tokenized foreign securities; and the Reserve Bank of India has historically maintained a cautious posture toward offshore DeFi activity. Users in markets with similar regulatory ambiguity should verify local compliance requirements independently. Cash App's announced USDC send and receive support on Arbitrum provides one concrete mechanism being developed for South Asia remittance corridors, routing funds from US diaspora users through Arbitrum to recipients in India, though the regulatory environment for such flows remains unsettled.

Weeks before Robinhood Chain went live, Mastercard announced it would use Arbitrum as one of its supported blockchain networks for stablecoin settlement, accepting USDC, PayPal's PYUSD, USDG, RLUSD, and SoFiUSD. PayPal's PYUSD had already demonstrated meaningful scale on the network, peaking at $428 million on Arbitrum in Q1 2026, which validated the currency's real-world presence ahead of the Mastercard announcement. The system enables 24-hour, seven-day settlement including weekends and holidays, a significant operational change for card network participants accustomed to traditional settlement batch cycles. Initial participants include ARQ (formerly DolarApp), CBW Bank, Cross River, Lead Bank, and Nuvei, with expansion planned across Latin America and beyond. ARQ's focus on Latin America is directly relevant to Mastercard's initial live deployment markets in that region. Sub-Saharan Africa is a planned next phase rather than a current deployment, and for users in those markets, as well as in South Asia, the integration could eventually allow merchants to receive stablecoin settlement without needing to interact directly with DeFi platforms. The Mastercard rollout is still in early stages and its regional expansion timeline has not been confirmed.

The broader Arbitrum network added 474 million transactions in the first half of 2026, including an all-time monthly high of 133 million transactions in February 2026, bringing the lifetime total to 2.7 billion. The protocol's Chain GDP, Arbitrum's proprietary measure of economic activity conducted on-chain, surpassed $1.7 billion, up 45 percent year over year. Stablecoin holders on the network reached 10.5 million, a 40 percent increase, with monthly stablecoin volumes exceeding $60 billion. Real-world asset (RWA) deployment grew threefold year over year to roughly $850 million across more than 2,000 tokenized assets. Spiko accounted for over $440 million in tokenized government debt products, Securitize-linked assets contributed more than $150 million, and Franklin Templeton's BENJI added approximately $50 million. The ArbitrumDAO's STEP 2.0 governance initiative allocated 35 million ARB toward RWA products from WisdomTree, Spiko, and Franklin Templeton, reflecting a DAO-level commitment to the category. Derivatives open interest grew 434 percent over six months, peaking at $1.5 billion. LG Electronics also announced a blockchain-based on-chain advertising network built on Arbitrum, illustrating institutional adoption extending beyond financial services.

The ArbitrumDAO treasury now holds more than $125 million in non-native assets including ETH, RWAs, and stablecoins, a deliberate move away from ARB-denominated reserves that reduces governance and operational risk. The DAO reported gross margins above 97 percent across its protocol revenue streams. A proposed $43.5 million Foundation budget for 2027 is pending an on-chain governance vote.

Looking forward, Arbitrum has described ZK-proof settlement and confidentiality infrastructure as in development, targeting regulated financial applications where transaction privacy is a compliance requirement.

With 1,142 live protocols and more than 30 chains operating under the AEP, Arbitrum enters the second half of 2026 with growth distributed across institutional deployments, retail DeFi, and derivatives activity. Together with Base, the network holds approximately 77 percent of Ethereum Layer 2 total value locked, a position it will look to reinforce as institutional chains like Robinhood's move from launch momentum toward durable, recurring revenue at scale.
