- Is a Perp DEX Safe? Custody, Exits and LiquidationsNon-custodial is a label, not an answer. Six questions to ask any perp DEX about custody, exits, reversed fills, liquidation and audits before you deposit.
- Arcus Incident ReportTrade tokenized stocks and perpetuals 24/7 on Arcus, a self-custodial DEX on Robinhood Chain. Zero spot fees.
- Multi-Asset Collateral Is Now Available to Every Trader on ArcusEligible Stock Tokens and Wrapped ETH can now back perps positions on every Arcus account - no volume requirement, nothing to enable.
- Arcus Invite Codes: UpdatedArcus invite codes now come with a 30-day activation window: redeem a code, then deposit or trade perpetuals to keep your access - spot doesn’t count. Codes spent on accounts that never activate are automatically…
Arcus is in beta and access is invite only. Matching runs on Arcus servers and a permissioned validator set; if they go offline, trades since the last committed state can be reversed. Leverage can lead to liquidation, and Stock Tokens carry tracking and redemption risks. Outside regular trading hours, initial margin on stock, commodity and index perps goes up (maintenance margin does not), so buying power can shrink overnight and on weekends with no price move.
