Remaining: Fund deployer wallet, run deploy script, fill contract addresses in docs and .env

✅ Phase 2 Task 6: Security Audit (Internal)

Status: ✅ INTERNAL AUDIT COMPLETE

Completed:

• Blockchain integration: key handling, replay protection (nonce + chainId), gas estimation with buffer, transaction confirmation and retry
• PQC handling: entropy via liboqs CSPRNG (or secrets.token_bytes fallback), liboqs constant-time verification, key lifecycle assessment

• Smart contract: reentrancy analysis, access control, overflow protection (Solidity 0.8.19)
• Findings and remediations documented in docs/next-phase/SECURITY_AUDIT_CHECKLIST.md

Recommended: External third-party audit before mainnet deployment
