## 🛡️ Security & Edge Case Validation

### Input Validation
- **Very long wallet names**: Properly rejected (>255 characters)
- **Special characters**: Correctly blocked in wallet names
- **Unicode characters**: Handled according to ASCII-only policy
- **Empty configurations**: Properly rejected with validation error
- **Port boundaries**: Validated min/max RPC port ranges

### Network Isolation
