## 💡 RECOMMENDATIONS

### Immediate Actions (Do Today)
1. **Focus on security hardening** before production planning

3. **Do not deploy any code** to mainnet until security review complete
4. **Start with testnet only** for all initial testing

### Short-term Strategy (Next 2 weeks)
1. **Implement comprehensive testing** before any live deployment
2. **Start with small amounts** ($10-100) for initial live testing
3. **Gradually scale up** only after proving profitability and safety
4. **Monitor everything** - implement comprehensive observability

### Long-term Strategy (Next month)
1. **Build automated testing pipeline** for continuous security validation
2. **Implement advanced risk management** for larger capital deployment
3. **Scale gradually** based on proven performance metrics
4. **Consider institutional-grade security** for larger deployments
