## Remaining Tasks (Lower Priority)

### High Priority (Still Pending)
1. ⚠️ **Web3Signer Key Import** - Service ready, needs keys
2. ⚠️ **Monitor Cloudflare Improvements** - Need 24h monitoring
3. ⚠️ **Complete Monitoring Automation** - Script ready, needs automation

### Medium Priority
- Configure wallet allowlist
- Set up Redis password
- Complete metrics collection

## Recommendations

### Immediate (This Week)
1. **Monitor Success Rate**: Track if 80% success rate is maintained
2. **Import Web3Signer Keys**: Enable transaction signing
3. **Automate Monitoring**: Set up cron job for monitoring script

### Short-term (This Month)
1. **Complete Monitoring**: Full Prometheus/Grafana setup
2. **Security Hardening**: Wallet allowlist, Redis password
3. **Load Testing**: Understand capacity limits
