Mark Price System

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

• 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
