Module: Oracle - Price Feed and Data Integration

[devIKargi]

Purpose

Implement an oracle module to integrate external price feeds and data into the protocol, enabling accurate pricing for token swaps, collateral valuation, and liquidation mechanisms.

Direction / Tasks

• Implement Chainlink price feed integration for primary oracle
• Add fallback oracle mechanism using alternative data sources
• Create price validation and staleness checks
• Support multiple asset pairs with configurable update frequencies
• Implement circuit breaker to halt operations on price anomalies
• Add historical price tracking for TWAP calculations
• Create price deviation alerts for monitoring
• Integrate with AccessControl for feed administrator functions

Acceptance Criteria

• Chainlink feeds properly integrated and queryable
• Fallback oracle activates on primary feed failure
• Staleness checks prevent outdated price usage
• Price anomalies trigger circuit breaker protection
• TWAP calculations accurate over specified windows
• Multiple asset pairs supported simultaneously
• All price updates emitted as events
• 100% unit test coverage including failure scenarios
• Gas-efficient price retrieval (batching support)
