Robinhood launched the mainnet of its Layer 2 chain, Robinhood Chain, on July 2, introducing tokenized stocks, on-chain lending, AI trading, and more. While major DeFi protocols quickly integrated, the announcement of a new DEX called Arcus—built on Robinhood Chain by the dYdX team—sparked fierce backlash. Community members accused the team of diverting resources and risking DYDX token dilution, sending DYDX down 40.7% in one day.

Robinhood Chain Mainnet Launch: Product Suite and Market Reaction

On July 2, Robinhood held "The World is Flat" event in London, officially unveiling the mainnet of its Layer 2 blockchain, Robinhood Chain. Built on Arbitrum Orbit, the chain is designed for institutional-grade applications and AI-native architectures, with specific optimizations for real-world assets (RWA). Following the announcement, Robinhood's stock surged 8.35% to $108.6, hitting a six-month high.

Robinhood simultaneously expanded its on-chain product portfolio around the chain:

  • Tokenized Stocks: Robinhood Wallet now supports tokenized stock trading in over 120 countries. Users can trade via DEXs such as Uniswap, 1inch, Rialto, Lighter, and Arcus, and can use the tokens as collateral for lending or add them to liquidity pools.
  • On-Chain Perpetuals: The wallet offers perpetual contracts on stocks, commodities, and other assets, with 90-day fee and gas subsidies for early adopters.
  • On-Chain Lending (Robinhood Earn): Available to U.S. users, depositing USDG stablecoins yields an estimated 7% APY. The product is powered by Morpho’s lending infrastructure and backed by Steakhouse, Ethena, Spark, Maple, and others, with an insurance mechanism.
  • AI Trading (Agentic Accounts): A crypto version of AI-powered trading agents that allow users to set risk parameters and capital boundaries, with the AI autonomously scanning markets and executing strategies.

Robinhood’s crypto revenue fell 47% year-over-year in Q1 to $134 million, and crypto notional trading volume dropped 48% to $24 billion. The chain expansion is seen as a crucial move to reignite growth.

Protocol Onboarding and the dYdX Community Firestorm

Leveraging its massive user base (approximately 27.7 million funded accounts), Robinhood Chain quickly attracted top protocols including Uniswap, 1inch, Lighter, Morpho, Chainlink, BitGo, Ethena, and EtherFi. But the most controversial announcement came from the dYdX Foundation: a new DEX called Arcus, built on Robinhood Chain.

Arcus supports 95 tokenized stocks, perpetuals, and major crypto assets, with plans to allow tokenized stocks and crypto as collateral for perpetuals, and to offer Pre-IPO equity trading (e.g., OpenAI). It is currently in beta, targeting a full launch in late 2026. Crucially, Arcus does not run on dYdX Chain but operates as an independent product.

dYdX founder Antonio explained in an open letter that the team realized dYdX Chain forced trade-offs between performance, UX, and decentralization, while competitors with faster execution, simpler products, and deeper liquidity were winning market share. After months of user feedback, they chose Robinhood Chain for its ready-made user base and liquidity. Arcus also received a strategic investment from Robinhood Crypto.

The move ignited immediate backlash from the dYdX community. Critics fear that:

  • The core team is effectively spinning off a new brand, diverting development resources and market attention away from dYdX, potentially cannibalizing its value.
  • Arcus’s potential token launch will lure traders and liquidity, reducing dYdX Chain activity and further diluting DYDX token value.
  • Given that dYdX conducted one of the largest airdrops in crypto history, Arcus could repeat that playbook.

The dYdX Foundation responded that its commitment to the dYdX protocol and governance remains unchanged. dYdX Chain continues to operate normally—trading, deposits, withdrawals, staking, and governance all function. DYDX token governance and staking rewards (paid in USDC) are unaffected, and community treasuries remain under DYDX holder control. Antonio, who claims to be the largest DYDX holder, stated his interests are deeply aligned with the community. He promised that if Arcus launches a token, a portion will be reserved for dYdX community distribution, and Arcus will prioritize access for dYdX traders. Nonetheless, the market reacted harshly: DYDX fell approximately 40.7% on the day of the announcement.

Outlook: From Brokerage to Global Financial Gateway

Robinhood’s ambition extends far beyond a single L2 chain. With ~28 million users, a mature brokerage business, and expanding global compliance (Canada launch, Singapore MAS license, European perpetuals for commodities/ETFs/forex, and upcoming UK crypto trading), the company aims to pivot from an internet brokerage into the next-generation global financial entry point. Whether that vision becomes reality remains to be tested by market adoption and competitive dynamics.
