The mainnet went live at a public event held at the Old Royal Naval College in London. The launch followed earlier groundwork: Robinhood had deployed Classic Stock Tokens on Arbitrum One for European customers in 2025 before migrating to a dedicated chain, a progression that makes the network's rapid testnet maturity more intelligible. Built on Arbitrum's Orbit framework, which allows institutions to deploy customized chains that settle to Ethereum mainnet, Robinhood Chain is now the 30th or more dedicated chain on the Arbitrum platform. It runs with 100ms latency, configurable block times, and preconfirmation support, and uses ETH as its gas token. The network had already handled more than 200 million transactions during its testnet phase before going live.

During its first seven days of operation, the chain generated approximately $800,000 in protocol revenue. Primary reporting at launch projected that figure to roughly $42 million annualized; the Arbitrum H1 2026 Report, measured at the two-week mark, places the annualized figure closer to $23 million. A portion of that revenue flows back to the Arbitrum ecosystem under the Arbitrum Expansion Program (AEP) licensing arrangement: 10 percent of Robinhood Chain's net protocol revenue returns to Arbitrum's governance structure, split between the ArbitrumDAO treasury (8 percent) and the Arbitrum Developer Guild (2 percent). The ARB token responded sharply to the chain's launch, climbing 19 percent as on-chain volume spiked, and Robinhood Chain's TVL contribution to the Arbitrum ecosystem reached $241 million. As of July 16, ARB trades around $0.087, giving it a market cap of approximately $555 million; the token has seen significant volatility in July 2026 and readers should verify this figure against current market data.

The chain's flagship product is a suite of tokenized stock tokens covering more than 120 countries through Robinhood Wallet. Users in eligible jurisdictions can trade representations of US equities around the clock via integrations with Uniswap, 1inch, Rialto, Lighter, and Arcus. One critical detail that prospective users should understand: these tokens are not equity. They are tokenized debt securities issued by Robinhood Assets (Jersey) Limited, a structure that provides price exposure to the underlying stock but grants no shareholder rights, voting rights, or legal ownership in the referenced company. Robinhood's own documentation states that the instruments "do not grant investors any legal or beneficial rights in those underlying securities." The tokens are also blocked for residents of the United States, United Kingdom, Canada, Switzerland, and the UAE, among other jurisdictions. Johann Kerbrat, Robinhood's SVP and General Manager of Crypto and International, framed the launch as bringing "the best of traditional finance and DeFi together, and in doing so, expanding financial ownership to every corner of the globe," though the geographic carve-outs are substantial.

Alongside the chain launch, Offchain Labs, the company behind Arbitrum's core technology, released ZeroDev Wallet on July 7. ZeroDev was previously an independent smart account infrastructure company before being acquired by Offchain Labs. The new wallet product consolidates what developers previously had to source from multiple vendors: authentication (via email, OAuth, or passkeys), gas fee sponsorship so users can transact without holding ETH, session keys for pre-approved transactions, transaction batching, policy controls, and account recovery. It targets enterprise and fintech teams building onchain products. The vertical integration raises a straightforward question worth tracking: as Offchain Labs both builds Arbitrum's core infrastructure and sells developer tooling, ecosystem participants should watch for whether independent alternatives receive equal promotion.

The launch coincided with the Arbitrum Foundation's Founder House London, a three-day accelerator that ran July 10 through 12. More than 490 builders applied; 140 were selected and 64 projects competed for a share of $300,000 in prizes and grants. Robinhood Chain served as a headline sponsor, with mentorship also provided by Offchain Labs, the Arbitrum Foundation, AWS, Alchemy, ZeroDev, GMX, Dune, OpenZeppelin, and the UK's Centre for Finance, Innovation and Technology. Focus areas included tokenized capital markets, collateral and risk infrastructure, payments, tokenized equity, yield products, and agentic finance, a term Robinhood's newsroom has used to describe systems in which software agents execute trading decisions autonomously on behalf of users. Winners had not been publicly announced as of this article's publication date; results are expected to be posted on the Arbitrum Foundation blog.

For users and developers outside the US and Western Europe, the picture is uneven. Arbitrum has been active in South Asia, running a hacker house in Bengaluru in 2025 that distributed $70,000 in prizes across four tracks: DeFi, privacy, onchain insurance, and developer tools. India's large retail trading base and mobile-first user behavior make the ZeroDev gasless wallet architecture particularly relevant, though it remains unclear whether India is included in Robinhood's 120-country stock token rollout. Regulatory guidance from India's SEBI on tokenized securities has not been finalized; the GIFT City sandbox currently represents the most likely near-term path for institutional access in the country. In Africa, Robinhood's direct product is largely inaccessible, but the chain's open infrastructure means any developer can deploy protocols on top of it, and Arbitrum's stablecoin rails, which process more than $60 billion in monthly transfer volume, have found early use in some regional remittance applications, according to industry observers.

The broader context for all of this is the rapid growth of tokenized real-world assets. On-chain RWA value crossed $36 billion globally in 2026, and Arbitrum already leads all chains with more than 2,000 tokenized assets and roughly $850 million in assets under management. Robinhood Chain's entry puts a major retail brokerage brand directly in that infrastructure layer. How regulators across Asia and Africa treat tokenized debt instruments in the coming months will largely determine how far that reach extends.
