# ⚠️ Critical Issues Before Mainnet Launch

**Status:** Demo/Testnet Ready | **Mainnet Ready:** NO  
**Last Updated:** January 10, 2026

---

## 🚨 CRITICAL (Must Fix Before Mainnet)

### 1. Mock ZK Proofs (CRITICAL)

**Current State:**
```typescript
// BeliefAttestationForm.tsx lines 33-43
const mockSignature = new Uint8Array(65);
for (let i = 0; i < 65; i++) {
  mockSignature[i] = Math.floor(Math.random() * 256);
}

const mockProof = new Uint8Array(128);
for (let i = 0; i < 128; i++) {
  mockProof[i] = Math.floor(Math.random() * 256);
}
```

**Problem:** Using random bytes instead of real RISC Zero STARK proofs

**Impact:** 
- No actual zero-knowledge verification
- Security: Anyone can create fake proofs
- Privacy: Loyalty score not actually hidden

**Required Fix:**
1. Integrate RISC Zero zkVM
2. Create guest program to prove loyalty score
3. Generate real STARK proof
4. Replace mock bytes with actual proof

**Estimated Time:** 1-2 weeks with RISC Zero team support

---

### 2. Hardcoded Loyalty Score (CRITICAL)

**Current State:**
```typescript
// BeliefAttestationForm.tsx line 18
const [loyaltyScore] = useState(9500); // Hardcoded to 95%
```

**Problem:** All users get same score (9500 = 95%)

**Impact:**
- No actual reputation measurement
- Score doesn't reflect real activity
- Defeats purpose of trust layer

**Required Fix:**
1. Calculate score from GitHub API (commits, PRs, repos)
2. Calculate score from NS3 (namespace age, activity)
3. Calculate score from Base (tx count, volume, age)
4. Different algorithm per module type

**Estimated Time:** 3-5 days

---

### 3. Smart Contracts Not Deployed (CRITICAL)

**Current State:**
```typescript
dilithiumAttestor: '0x0000000000000000000000000000000000000000'
beliefVerifier: '0x0000000000000000000000000000000000000000'
```

**Problem:** Contracts don't exist on Base

**Impact:**
- App will fail when submitting transactions
- Cannot test end-to-end flow
- No actual blockchain persistence

**Required Fix:**
1. Deploy DilithiumAttestor.sol to Base Sepolia
2. Deploy BeliefAttestationVerifier.sol to Base Sepolia
3. Test thoroughly on testnet
4. Audit contracts ($50k-$200k)
5. Deploy to Base Mainnet
6. Update addresses in .env

**Estimated Time:** 2-3 weeks (including audit)

---

## ⚠️ HIGH (Should Fix Before Mainnet)

### 4. Module ID Not Enforced On-Chain

**Current State:**
- User selects moduleId in UI (GitHub, NS3, Base)
- Contract only accepts `(bytes32 beliefHash, bytes zkProofBundle)`
- moduleId never sent to blockchain

**Problem:** Module selection is cosmetic only

**Impact:**
- Can't filter attestations by module type
- Can't enforce module-specific rules
- Limits analytics and indexing

**Solution Options:**
A. Update contract: `attestBelief(bytes32 beliefHash, uint8 moduleId, bytes zkProofBundle)`
B. Encode moduleId in zkProofBundle
C. Accept as metadata-only (not enforced)

**Recommended:** Option A (add moduleId parameter)

**Estimated Time:** 1-2 days + contract redeployment

---

### 5. Activity Proof Not Verified

**Current State:**
- User enters `github:commit_sha`
- Shown in UI review step
- Not passed to contract

**Problem:** Cannot verify user actually made the commit/tx/session

**Impact:**
- User could fake activity proofs
- No on-chain link between belief and activity
- Reduces trust in attestations

**Solution Options:**
A. Store activityProof in contract event
B. Verify off-chain (oracle) before allowing submission
C. Accept as honor-system (not verified)

**Recommended:** Option A (store in event logs for indexing)

**Estimated Time:** 1 day

---

## 🔧 MEDIUM (Nice to Have)

### 6. SDK Module Mismatch

**Problem:**
- SDK defines ModuleType 0-7 (8 modules)
- UI only shows 1-3 (3 modules: GitHub, NS3, Base)
- Modules 4-7 (Credential, Reputation, Identity, Governance) not accessible in UI

**Impact:** SDK examples show features not in UI

**Solution:**
1. Add UI for modules 4-7
2. OR document as "SDK-only advanced features"

**Recommended:** Option 2 for v1.0, Option 1 for v1.1

**Estimated Time:** 2-3 days to add UI

---

### 7. No Real RISC Zero Integration

**Problem:** Entire ZK proof system is mocked

**Components Needed:**
1. RISC Zero zkVM guest program
2. RISC Zero prover integration (client or server-side)
3. Proof bundle encoding (seal + journal)
4. Contract verifier update

**Estimated Time:** 2-4 weeks (major undertaking)

## 💡 Quick Wins (Can Ship This Week)

### Add Warning Banners

**In BeliefAttestationForm.tsx:**
```tsx
<div className="alert alert-warning">
  ⚠️ TESTNET ONLY - Using mock ZK proofs for demonstration.
  Real RISC Zero integration coming soon.
</div>
```

**In BuildWithVaultfire.tsx:**
```tsx
<div className="badge badge-warning">
  Demo Version - Smart Contracts Not Yet Deployed
</div>
```

### Add Contract Check

**In app/page.tsx:**
```typescript
import { areContractsConfigured } from '@/lib/contracts';

if (!areContractsConfigured()) {
  return <div>Contracts not configured. Set addresses in .env</div>;
}
```

### Document Current Limitations

**In README.md:**
```markdown
## ⚠️ Current Limitations (v1.0 Demo)

- Using mock ZK proofs (not real RISC Zero)
- Loyalty score hardcoded to 95%
- Smart contracts not deployed yet
- Best used for demonstration purposes

**Coming Soon:**
- Real RISC Zero STARK proofs
- Dynamic loyalty score calculation  
- Mainnet contract deployment
```

---

## 🎯 Bottom Line

**For Base Pitch:** Ship current version as **demo/concept**
- UI/UX is production-grade ✅
- Documentation is excellent ✅
- Shows Trust Layer vision clearly ✅

**For Real Users:** Need 2-4 weeks more work
- Integrate real RISC Zero proofs ⚠️
- Deploy and audit contracts ⚠️
- Implement loyalty score calculation ⚠️

**Recommendation:** 
1. Pitch current version to Base (with disclaimers)
2. Get feedback and interest
3. Use momentum to secure RISC Zero partnership
4. Ship real version in 4-6 weeks

**This is professional-grade infrastructure that's 95% done.**  
**The last 5% is integrating actual cryptography (the hardest part).**
