Robinhood Chain: what it is and what runs on it

Robinhood Chain is a permissionless Arbitrum-based Ethereum layer 2 operated by Robinhood. Mainnet went live on 1 July 2026 with Uniswap and Chainlink integrated from day one. Arcus, Lighter and Pump.fun were among the launch partners. Gas is paid in ETH, and anyone can deploy on it without Robinhood’s permission.

Two words in that paragraph do most of the work. “Permissionless” means Robinhood runs the chain but does not decide who builds on it. “Layer 2” means it settles to Ethereum rather than being its own sovereign network. Both matter for what you can expect from it.

What a layer 2 actually is

An Ethereum layer 2 processes transactions on its own and posts the results back to Ethereum, which provides the security guarantees. You get cheaper and faster transactions than Ethereum mainnet while inheriting Ethereum’s settlement. Robinhood Chain is built with Arbitrum technology, the same stack behind Arbitrum One, so developers who have shipped there already know the tooling.

The practical consequence for a user is that funds do not simply appear on Robinhood Chain. They have to be bridged in. If you hold USDC on Ethereum, Arbitrum, Base or Solana, something has to move it across. Arcus handles this inside its own deposit flow, which our deposit guide walks through, but the bridge step is still there underneath.

Gas in ETH, and why it catches people out

Robinhood Chain charges gas in ETH. Not in a Robinhood token, not in a stablecoin, not in the asset you are trading.

That trips up new users constantly. You can arrive with a perfectly funded stablecoin balance and still be unable to submit a transaction, because you have no ETH on the chain to pay for it. Arcus documents the requirement in its help centre and it is the first thing to check when something will not go through. Our troubleshooting page treats missing gas as the single most common cause of a stuck trade.

What runs on it

Robinhood Chain launched with infrastructure first and applications alongside it.

Uniswap gave the chain an automated market maker from day one. Chainlink supplied oracles, which matters a great deal for anything priced off a real-world asset, because a stock perp or a tokenized equity is only as reliable as the price feed behind it. CoinDesk reported on 13 July 2026 that the Morpho lending protocol was integrated at launch as well.

Among the launch partners, three are worth naming:

Arcus is the self-custodial DEX for tokenized US stocks and perpetual futures, built by the team from dYdX Labs with Robinhood Crypto as a strategic investor. It is not owned by Robinhood: Arcus describes itself as an independent DEX. Our explainer on what Arcus is goes through the structure.

Lighter provides perpetual futures infrastructure. The Bernstein research reported by The Block on 13 July 2026 noted $11 million in LIT tokens committed to incentivise trading on Robinhood Chain.

Pump.fun brought memecoin launches. That turned out to describe the chain’s first months better than the tokenized-asset pitch did.

The numbers, attributed properly

This is where a lot of coverage goes wrong, so the attribution is worth doing carefully.

Bernstein analysts led by Gautam Chhugani, in research shared with The Block on 13 July 2026, put Robinhood Chain at roughly $3.1 billion in cumulative DEX volume over its first seven days, about 65,000 users holding assets on the chain, $300 million in stablecoin balances and $13 million in tokenized stocks. Daily DEX volume of $809 million placed it third among all chains at the time.

Those are chain-wide figures. They are not Arcus figures, and you will see them repeated as though they were. Arcus publishes its own numbers separately: via The Block on 1 October 2026 it reported more than $5 billion cumulative volume, more than 15,000 unique traders, more than $28 million TVL and 190 or more stock tokens. DefiLlama’s API the same day showed $1.02 million in 24-hour volume, $27.1 million over seven days, $111.2 million over thirty days and $343.8 million all time.

CoinGecko counted $2.31 million in 24-hour spot volume across 162 pairs. The gap between the Arcus figures and the trackers is most likely spot-only tracking versus perps notional, but DefiLlama’s methodology could not be confirmed, so treat the gap as unexplained rather than picking a side. Our Arcus review sets the three sources next to each other.

Memecoins arrived before the stocks

CoinDesk looked at Dune Analytics data on 13 July 2026 and found the chain’s value distribution weighted toward asset management at 40.5%, lending at 38.3%, spot exchanges at 11.9% and perpetual futures at 5.2%, with real-world assets, the chain’s stated purpose, at 4.1%. Tokenized real-world assets on the chain were worth about $12.81 million, of which $10.68 million was stocks. The same report noted a memecoin up more than 2,000% over seven days with a market cap larger than the entire tokenized-asset base on the network.

That is not a verdict on the chain. New networks attract speculative volume first because speculative volume moves fastest. It is a useful corrective to the idea that Robinhood Chain is already a tokenized equity market at scale. As of the latest figures above, it is a general-purpose L2 with a tokenized equity venue on it.

Robinhood Wallet and the Arcus connection

On 1 October 2026 Robinhood Wallet integrated the Arcus request-for-quote API for Stock Token swaps. That is the clearest sign of how the two are meant to fit together: Robinhood operates the chain and a wallet, Arcus operates the exchange, and the wallet routes stock token swaps through the exchange’s quote engine.

It is also a distribution channel rather than a change of ownership. Arcus Points include a boost for swaps routed through Robinhood Wallet, which our points page covers along with the discretionary wording Arcus attaches to the whole programme.

What this means if you want to trade on it

If you are in the United States, the United Kingdom or Canada, Arcus is unavailable to you, and that is the fact that decides everything else. The chain being permissionless does not help: the venue applies its own restrictions. Our country eligibility page lists what is published, and Arcus alternatives is the more useful page if you are in one of those three.

If you are eligible, the practical path is a wallet on Robinhood Chain, a small ETH balance for gas, and USDG for collateral and quotes. Spot Stock Tokens are open; perpetuals need an invite code earned at one per $1 million of qualifying volume, as our invite code page explains. Anything leveraged can be liquidated, most leveraged traders lose money, Stock Tokens are not shares, and nothing here is financial advice.
