Arcus describes itself as a decentralized exchange built in partnership with Robinhood on Robinhood Chain, trading Stock Tokens spot plus perpetuals across equities, crypto, commodities and indices (https://arcus.xyz/). The Block reports it was built by the team behind dYdX and that it launched ERC-20 'pTokens' for perp positions in August 2026 (https://www.theblock.co/news/defi/2026-08-25-robinhood-chain-dex-arcus-ptokens-perps-erc-20s-412696). The docs cover REST and WebSocket APIs with Ed25519-key request signing (https://docs.arcus.xyz). The MCP server at https://docs.arcus.xyz/mcp serves API documentation only and does not place trades (https://docs.arcus.xyz/ai-tools/mcp). Robinhood's chain docs list Arcus as a perpetuals DEX partner (https://docs.robinhood.com/chain/), and Arcus says it is not available in the US, UK or Canada.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden.
Last 30 days — to 2026-11-07, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
