Ostium, an Arbitrum-based RWA perpetuals DEX, confirmed an anomaly in its OLP vault, halted all trading, and is investigating after an estimated $18M attack. The incident is negative for Arbitrum DeFi sentiment and can tighten risk appetite toward smaller perp venues, increasing counterparty and smart-contract risk premia and potentially pressuring activity and liquidity across the Arbitrum ecosystem in the near term.
