Core Contracts

Summary

The implementation of RAACPrimeRateOracle does not align with the design specified in the documentation. Key discrepancies include:

• Missing Time-Based Update Interval: No mechanism to enforce a minimum delay between price updates, risking excessive frequency.

• Incorrect Function Implementation: The setHousePrice function is used for oracle-driven price setting, while the documentation specifies that manual price updates should be handled by a separate updatePriceFromOracle method.

Impact

• Excessive Gas Costs: Unrestricted updates may drain funds through frequent transactions.

• Functional Ambiguity: Mixing automated and manual update logic risks bugs or unintended behavior.

Tools Used

• Manual Review

Recommendations

• Add a time-based update interval to prevent excessive frequency.

• Restructure Function Roles:
  Rename setHousePrice to updatePriceFromOracle for clarity.
  Reserve setHousePrice (if needed) for automated/internal adjustments.
