**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
- Oracle fulfillment: commit-reveal integrity verified on-chain, race condition analysis (Python GIL + async), input validation via FastAPI/Pydantic
- 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

## Next Steps

1. **Complete Dashboard Integration** (Task 3)
   - Priority: High (user-facing)
   - Effort: Medium

2. **Add Monitoring Metrics** (Task 4)
   - Priority: High (production readiness)
   - Effort: Medium

3. **Deploy to Testnets** (Task 5)
   - Priority: Medium (validation)
   - Effort: High

4. **Security Audit** (Task 6)
   - Priority: High (production requirement)
   - Effort: High (external)

## Next Steps (Post Phase 2)

1. **Deploy to Testnets** — Fund deployer wallet, run `npx hardhat run scripts/deploy-all-testnets.js`, fill contract addresses
2. **External Security Audit** — Engage third-party auditor before mainnet deployment
3. **Mainnet Deployment** — Deploy to production networks after audit clears
4. **Phase 3** — See `quantum-oracle/DEVELOPMENT_ROADMAP.md` for future roadmap
