Tool: Slither v0.11.5 (static analysis)
Contract: contracts/MantleIntelAudit.sol
Compiler: solc 0.8.20
Date: June 2026
Result: 0 High / 0 Critical findings

Detector: timestamp
Location: MantleIntelAudit.getFinding() — line 196
Slither finding:

MantleIntelAudit.getFinding(uint256) uses timestamp for comparisons
Dangerous comparisons: require(bool,string)(findings[findingId].exists, "Finding not found")

Assessment: False positive. The flagged require statement checks a boolean existence flag (findings[findingId].exists), not a timestamp value. No block timestamp manipulation can affect this comparison. No action required.

Detector: solc-version
Location: pragma solidity ^0.8.20
Slither finding: Version 0.8.20 contains compiler-level known issues:

• VerbatimInvalidDeduplication
• FullInlinerNonExpressionSplitArgumentEvaluationOrder
• MissingSideEffectsOnSelectorAccess

Assessment: None of these compiler bugs affect MantleIntelAudit.sol. The contract does not use verbatim assembly, inline function splitting, or selector-based dispatch patterns that would trigger these issues. This is a standard informational warning applied to all 0.8.20 contracts.

Detector: immutable-states
Location: MantleIntelAudit.owner — line 77
Slither finding: owner is set once in the constructor and never modified — could be declared immutable for gas savings.

Assessment: Valid gas optimization. The owner variable is set at deployment and is intentionally not immutable to preserve upgrade flexibility. Impact is minimal (~2,100 gas savings per deployment). No security risk.

Slither static analysis found zero critical or high severity vulnerabilities in MantleIntelAudit.sol. The single low-severity finding is a false positive. Both informational findings are acknowledged and do not affect contract security or correctness.

The contract's core functions — submitFinding(), getPublicFindings(), getFinding() — are free of reentrancy, integer overflow, access control, and logic vulnerabilities.

The authorizedAgent role is currently held by a single EOA. Before mainnet deployment, this should be upgraded to a Gnosis Safe 2-of-3 multi-sig to eliminate the single point of failure. See MULTISIG.md for the full setup guide and security checklist.

1. GitHub Actions CI/CD — Replace manual builds with hosted CI pipeline
2. Container signing — Sign Docker images with cosign (Sigstore)
3. SBOM generation — Generate Software Bill of Materials with syft
4. Provenance attestation — Use slsa-github-generator for SLSA provenance
5. Verification — cosign verify-attestation for downstream consumers
