**How the Hub Architecture Works** — Learn about the Hub-Keyguard relationship, request behaviors, and security model.
**Need Lower-Level Control?** — For advanced use cases requiring direct blockchain access, consider using the [Web Client](https://nimiq.dev/web-client) or [RPC API](https://nimiq.dev/rpc).
## Hub Capabilities
Flexible integration options. Choose your integration style, access powerful methods, and support multiple chains.
**Security First**
The Hub uses a separate secure origin (Keyguard) to store and manage private keys. Your application **never** has access to user keys — all signing happens in the isolated Keyguard environment.
### Choose your integration style
