+# Smart Contract Audit Gap Checklist
+
+## Status
+- **Coverage**: 4% (insufficient for mainnet)
+- **Critical Gap**: No formal verification or audit for escrow, GPU rental payments, DAO governance
+
+## Immediate Actions (Blockers for Mainnet)
+
+### 1. Static Analysis
+- [ ] Run Slither on all contracts (`npm run slither`)
+- [ ] Review and remediate all high/medium findings
+
+### 2. Fuzz Testing
+- [ ] Add Foundry invariant fuzz tests for critical contracts
+- [ ] Target contracts: AIPowerRental, EscrowService, DynamicPricing, DAO Governor
+- [ ] Achieve >1000 runs per invariant with no failures
+
+### 3. Formal Verification (Optional but Recommended)
+- [ ] Specify key invariants (e.g., escrow balance never exceeds total deposits)
+- [ ] Use SMT solvers or formal verification tools
+
+### 4. External Audit
+- [ ] Engage a reputable audit firm
+- [ ] Provide full spec and threat model
+- [ ] Address all audit findings before mainnet
+
+## CI Integration
+- Slither step added to `.github/workflows/contracts-ci.yml`
+- Fuzz tests added in `contracts/test/fuzz/`
+- Foundry config in `contracts/foundry.toml`
+
+## Documentation
+- Document all assumptions and invariants
+- Maintain audit trail of fixes
+- Update security policy post-audit
+
+## Risk Until Complete
+- **High**: Escrow and payment flows unaudited
+- **Medium**: DAO governance unaudited
+- **Medium**: Dynamic pricing logic unaudited
+
+## Next Steps
+1. Run CI and review Slither findings
+2. Add more invariant tests
+3. Schedule external audit
