# Architecture & Features

Streamflow's technology stack is composed of three layers:

## Protocol layer

Streamflow Protocol is a base layer — a set of interoperable smart contracts that power the Streamflow Product Suite. These programs are built entirely on the Solana blockchain, enabling secure, efficient, and programmable token transfer infrastructure.

## Infrastructure layer

Streamflow offers powerful SDKs and APIs for faster development of applications.

This layer interacts with the **Protocol** layer.

To learn about the possibilities of the SDK and some of the existing integrations, find more information on this [page](https://streamflow.finance/integrations).

The composability and modularity of the infrastructure layer allow for a myriad of applications to be built on top of Streamflow. To understand the plans and the potential of the **infrastructure** layer, please read the section [Growing the Streamflow Ecosystem](https://docs.streamflow.finance/en/articles/9869368-growing-the-ecosystem).

## Business (Application) layer

This is the user-facing implementation of the protocol, such as the one at [app.streamflow.finance](http://app.streamflow.finance), that enables many end-user products.

While Streamflow encourages the ecosystem to build applications on top of the protocol and infrastructure layer, Streamflow also launched some of the end-to-end [solutions](https://docs.streamflow.finance/en/articles/9869339-solution).
