The SolidProof audit for ZKForge is now officially complete - and all previously identified issues have been fully resolved. The final result: zero risk findings. Throughout the process, SolidProof identified multiple issues across critical, high, medium, and low severities. After extensive fixes, verification, and refactoring: • All Critical issues resolved • All High issues resolved • All Medium issues resolved • All Low + Informational issues resolved Security remains our highest priority, especially when building advanced zkSTARK authentication. We took every auditor comment seriously, improved the entire system, and delivered a fully remediated platform. Final Words from SolidProof Below is a condensed overview of SolidProof’s final assessment: ZKForge V1 Security Re-Audit Analysis - Executive Overview The platform implements zero-knowledge encrypted messaging using a React/TypeScript frontend, Node.js/Express backend, MongoDB, and Solana integration. Key Security Achievements: • zkSTARK authentication with nonce-based replay protection (5-minute TTL) • Client-side proof generation ensures private keys never touch the backend • Password-based encryption using PBKDF2 (100k iterations) + AES-GCM 256-bit • Session tokens hashed with SHA-256 before storage • CORS restricted to trusted origins via environment variables • WebSocket authentication secured via subprotocols • Strict Ed25519 public key validation • Double-spend protection through safe balance validation • Nonce reuse detection to prevent cryptographic failures • Development-only logging for safer production behavior • NoSQL injection prevention and strict input sanitization • Global + endpoint-specific rate limits Conclusion: ZKForge V1 demonstrates strong security fundamentals with all critical and high-severity issues resolved. The zkSTARK authentication system is correctly implemented with replay protection, encryption is properly handled, CORS is secure, and frontend protections like React auto-escaping eliminate XSS vectors. Remaining notes relate only to code quality, not security. SolidProof recommends an independent cryptographic review before massive production scale. We appreciate the patience and trust of our community. We learned, we improved, and now we delivered. Audit link: app.solidproof.io/projects/z…
