🛡️ Slither Deep Audit Completed for Lattice L2 (Hybrid DAG + PQC + EVM)
I’ve completed a full Slither deep security audit of my Lattice Layer-2 smart contracts, a hybrid architecture combining DAG execution, Post-Quantum Cryptography (PQC), and EVM compatibility.
This was not a cosmetic audit — it focused on real attack surfaces, logic safety, and long-term maintainability.
✅ Final Security Status
High Severity: 0 issues
Medium Severity: 0 issues
Low Severity: Only minor documentation items remaining
All critical vulnerabilities have been resolved while preserving contract behavior and improving gas efficiency.
🔧 Key Fixes Implemented
🔴 High Severity
Fixed dangerous strict equality patterns across contracts that could cause unexpected reverts or bypass logic.
🟡 Medium Severity
Added missing event emissions for transparency and off-chain indexing
Eliminated variable shadowing issues
Verified and hardened low-level call safety
🟢 Low Severity
Optimized costly loops
Reviewed and documented timestamp dependencies
⚙️ Performance & Architecture Improvements
O(1) sequencer removal instead of O(n) searches
Improved validation logic for safer state transitions
Clear, consistent event emissions for monitoring and analytics
Security improvements also resulted in better gas efficiency and cleaner contract structure.

SECURITY_FIXES_COMPLETED.md — Detailed fixes and rationale
🚀 Conclusion
The Lattice L2 smart contracts are now production-ready, with a significantly stronger security posture and improved performance.
This audit reinforces the goal of Lattice:
secure, scalable infrastructure for next-generation blockchain systems, including DAG-based execution and post-quantum resilience — without sacrificing EVM compatibility.
More updates coming as the stack evolves.
