AdForensics Audit Summary

Audit Date: Completed July 31, 2025 Auditor: A&D Forensics Project: IFÁ Labs Oracle (price feed smart contracts) Codebase: https://github.com/IFA-Labs/oracle_contract (commit: 17f7ffc31a9818f35977ad042986cb72820d513b) Audit Delivery Date: July 31, 2025 Current Status (as of January 07, 2026): All identified issues resolved

Executive Summary

A&D Forensics conducted a comprehensive security audit of the IFÁ Labs oracle smart contracts using a combination of manual code review, automated tooling (including Mythril), and functional testing.

Key Outcome:

• No high or critical vulnerabilities were found.

• A total of 7 findings were identified:

  • 5 Low-severity issues

  • 2 Informational findings

• All 7 findings have been resolved by the IFÁ Labs team.

The audit confirms that the contracts follow good security practices for an oracle price feed system. The team addressed all reported issues, improving code clarity, robustness, and gas efficiency.

Summary of Findings

#	Title	Severity	Status	Fixed in commit (post-audit)
1	Inefficient Stale Check Allows Redundant Updates	Low	Resolved	Yes
2	Self-Pairing Allowed in Price Calculation	Low	Resolved	Yes
3	Lack of Zero-Price Validation in Submissions	Low	Resolved	Yes
4	Silent Reverts in Internal Functions	Low	Resolved	Yes
5	Indexing a Struct Provides No Searchable Value	Low	Resolved	Yes
6	Incorrect Error Reporting in Batch Pair Functions	Informational	Resolved	Yes
7	Unnecessary Comments and Inefficient Logic	Informational	Resolved	Yes

Highlights of Important Fixes

• Stale price check was corrected from > to >= to prevent redundant state updates.

• Zero-price submissions are now rejected, preventing potential division-by-zero errors in derived pair calculations.

• Self-pairing (same asset in both legs of a pair) is now explicitly blocked.

• Event indexing of structs was removed to avoid misleading developers and save gas.

• Error messages were added and corrected for better debugging experience.

• Code clarity was improved by removing unnecessary comments and refactoring inefficient logic.

Audit Methodology

The audit followed a three-step approach:

1. Manual Review – deep analysis of business logic and contract architecture

2. Automated Testing – static analysis with tools like Mythril

3. Functional Testing – unit tests and simulated exploit scenarios

Recommendations from the Auditor (Implemented)

The audit also included the following general recommendations, most of which were addressed during the remediation phase:

• Improve general coding style and structure

• Add comprehensive unit tests covering edge cases

• Provide detailed function comments for better readability

Current Security Posture

As of January 07, 2026, all reported findings have been fixed. The IFÁ Labs oracle contracts are considered to be in a good security state for deployment on Base mainnet and testnets, with no known critical or high-severity issues remaining from the audit.

Important note: Security is an ongoing process. We recommend:

• Regular re-audits after major changes

• Bug bounty program

• Monitoring of onchain update frequency and price deviations
