Opal's risk engine is designed to prevent system insolvency while protecting traders from predatory practices.

Mark Price System

Oracle Architecture Multi-provider aggregation for robust, manipulation-resistant pricing.

Primary Feeds

• Chainlink (high reliability, wide coverage)
• Pyth (low latency, high frequency)
• Blend methodology (finalized pre-launch)

Mark Price Calculation

• Medianized across providers
• Freshness constraints (maximum staleness)
• Deviation bounds per block
• Outlier rejection

Safeguards

• Heartbeat limits ensure continuous updates
• Circuit breakers on extreme deviations
• Failover to backup feeds during outages
• Manual intervention capability for edge cases
