## 7. Risk Assessment

### 🔴 HIGH RISK (Blocks Production)
1. **Zero test coverage** - Cannot verify correctness
2. **No security audit** - Vulnerabilities may exist
3. **Missing bridge integrations** - Cannot bridge tokens
4. **Incomplete eMoney integration** - Core functionality untested

### 🟡 MEDIUM RISK
1. Missing reserve system integration
2. Unclear architecture decisions
3. No monitoring infrastructure

### 🟢 LOW RISK
1. Documentation gaps (can be added incrementally)
2. Gas optimization (not critical for MVP)
3. Code quality improvements (post-MVP)

---

## 8. Recommended Next Steps

### Immediate (This Week)
1. Create test directories and basic test structure
2. Start with Core Ledger test suite
3. Begin security review documentation

### Short-term (Next 2 Weeks)
1. Complete all test suites
2. Create deployment scripts
3. Implement critical bridge integrations

### Medium-term (Next Month)
1. Complete security audits
2. Implement all bridge integrations
3. Set up monitoring infrastructure

### Long-term (Post-Mainnet)
1. Optimize gas usage
2. Enhance documentation
3. Implement advanced features
