Oracle Price
Price Oracles
Drake aggregates price feeds from multiple oracle networks to ensure accurate, reliable pricing across the platform.
Oracle Sources
Chainlink Data Streams Low-latency price feeds with sub-second updates. Prices are stored off-chain in signed reports and verified on-chain through Chainlink's verification contract when needed for trades, liquidations, or position updates.
Pyth Network High-frequency price updates providing additional redundancy and sub-second market data.
Future Integrations: Redstone, Stork, and other providers for maximum redundancy.
Price Aggregation
Drake combines multiple oracle sources through a simple process:
Fetch latest prices from all active sources
Normalize to common format (decimal/scaling adjustments)
Filter stale data (prices older than 60 seconds)
Remove invalid or zero values
Calculate simple average of valid prices
Apply aggregated price across the protocol
Off-chain operators continuously monitor oracle networks, detect price changes, bundle signed price data, and submit on-chain updates.
Usage
Aggregated oracle prices power:
AMM vault pricing
Margin calculations
Liquidation triggers
Funding rate calculations
Position valuation
Key Benefits
Low Latency — Sub-second price updates ensure trades execute based on current market conditions, matching centralized exchange performance.
Frontrunning Prevention — Real-time data combined with cryptographic verification protects trades from manipulation common in decentralized environments.
Decentralized Reliability — Multiple independent oracle networks provide redundancy while maintaining transparency and avoiding single points of failure.
Drake's multi-oracle approach delivers centralized exchange speed with decentralized security and transparency.
