Key Risks for Ostium Users
Ostium uses a custom-built oracle for pricing traditional assets. Unlike standard crypto feeds, it must handle market hours, trading halts, and corporate actions.
RWA perpetual profits and losses are settled via liquidity pools, not underlying assets. LP pool losses from one-sided markets could affect payout reliability.
Offering synthetic exposure to regulated securities on a decentralized platform creates regulatory uncertainty.
Top Risk Factors

- •Synthetic perpetual exposure to off-chain assets means no direct settlement in the underlying. Protocol relies on oracle accuracy and LP solvency to honor payouts.
- •Dual pool liquidity architecture with dynamic fees for RWA perpetuals is a novel market structure with limited precedent.
