Arcus Opens Multi-Asset Collateral for Perpetual Contracts to All Users

Decentralized trading platform Arcus has expanded its multi-asset collateral system to all user accounts, removing volume requirements that previously limited the feature to top-tier accounts ¹. The update allows traders to post tokenized equities and wrapped ether to support automated loans for perpetual contract positions ¹.

Under the mechanism, deposited assets remain in the user's perpetuals account and back automated loans denominated in USDG ¹. Arcus calculates margin needs dynamically: existing USDG deposits are utilized first, and any remaining margin shortfall is borrowed automatically against deposited tokens at a variable interest rate ¹. Collateral options at launch include $ETH (via Wrapped Ether) and nine tokenized equities: SPY, QQQ, AAPL, MSFT, GOOGL, AMZN, NVDA, META, and TSLA ¹. The move follows wider decentralized finance efforts to bridge equities into on-chain collateral engines, similar to initiatives like Robinhood's ERC-20 stock tokens ¹.

Margin Parameters and Liquidation Guardrails

Arcus set an initial loan-to-value (LTV) ratio of 50% across all eligible collateral, meaning $1 of deposited assets can back up to $0.50 of USDG borrowing ¹. Total per-account borrowing is capped at $10,000, while non-USDG collateral deposits are restricted to $20,000 per account ¹.

If an account's ratio rises to the maintenance LTV threshold of 60%—or exceeds the $10,000 borrowing ceiling—the protocol triggers liquidation ¹. During liquidation, open orders are canceled, cross-margin perpetual positions are closed, and trading and withdrawals are paused while positions settle ¹. Arcus stated that tokens are only liquidated at a discount to mark price to cover remaining deficits, and users can halt the process by depositing sufficient USDG before token sales conclude ¹. Arcus noted that the platform is not available in the United States, the United Kingdom, or Canada ¹.
