# Architecture

Glacis is a pure on-chain protocol, that means that all its components are Smart Contracts, these components can be aggregated in two groups:

* **Infrastructure Components**: Maintained by Glacis and deployed on each supported chain.
  * Router
  * Adapters
  * Mediators
* **Client Components**: Maintained by Glacis,accessible as package and deployed by user through the use of inheritance on his own contracts.
  * Clients

> All components have different behavior depending if they act as a source chain component or a destination chain component.
