Robinhood Partners With dYdX Labs to Launch Perpetuals DEX Arcus on Its New Blockchain
Robinhood and dYdX Labs are building a decentralized exchange called Arcus, set to run on Robinhood's new blockchain and offer perpetual contracts alongside tokenized stock trading. The move marks a rebranding of the dYdX protocol under the Arcus name as it migrates into Robinhood's emerging crypto infrastructure.
Key takeaways
- Robinhood and dYdX Labs are building a decentralized exchange called Arcus that will run on Robinhood's new proprietary blockchain and offer perpetual contracts alongside tokenized stock trading.
- Arcus represents a rebranding of the dYdX protocol as it migrates from its existing infrastructure into Robinhood's blockchain.
- Arcus will list perpetual contracts, which are synthetic derivatives that track an asset's price with no expiry date and carry significant liquidation risk for retail participants.
- Neither Robinhood nor dYdX Labs has publicly detailed how margin, liquidation, or asset custody will work on Arcus.
- Hosting the DEX on a proprietary chain rather than an established network like Ethereum or Solana gives Robinhood more control over transaction sequencing and fee capture but concentrates counterparty and technical risk on a single operator.

What Arcus Actually Is
Arcus is a decentralized exchange — a venue where trades settle directly on-chain without a centralized order book operator holding custody of funds. The product is being built by dYdX Labs, the development team behind the dYdX perpetuals protocol, which has operated as a standalone crypto-native platform through previous market cycles. The rebranding to Arcus coincides with the project's integration into Robinhood's proprietary blockchain rather than continuing on its existing infrastructure.
Perpetual contracts, the core instrument Arcus will list, are synthetic derivatives that track an asset's price with no expiry date. They are the dominant trading product in offshore crypto markets and carry significant liquidation risk for retail participants — a detail worth noting given Robinhood's predominantly retail user base.
Tokenized Stocks Add a Regulatory Wrinkle
The second product category — tokenized stocks — is the more structurally interesting element here. Tokenized equities are blockchain-based instruments that purport to track the price of publicly listed shares. Their regulatory status has remained contested, and the question of who is on the other side of those trades, and under what disclosure regime, is not addressed in what Robinhood and dYdX Labs have disclosed so far.
Robinhood launching its own blockchain represents a meaningful infrastructure commitment. Hosting a DEX on a proprietary chain rather than an established public network like Ethereum or Solana gives Robinhood more control over transaction sequencing and fee capture — but also concentrates counterparty and technical risk on a single operator.
The Mechanics to Watch
The partnership pairs a regulated U.S. broker-dealer with a crypto-native protocol shop. That combination could ease the compliance pathway for products like tokenized equities, or it could create friction if regulators treat the blockchain layer and the broker layer as a single entity. Neither Robinhood nor dYdX Labs has publicly detailed how margin, liquidation, or asset custody will work on Arcus.
What is clear: dYdX Labs is betting its protocol's future on Robinhood's infrastructure, and Robinhood is betting that a DEX bearing a crypto-native brand name accelerates its push into on-chain trading. Whether retail users end up better or worse off than on a centralized venue depends entirely on the mechanics — which have yet to be disclosed in full.
