# Learn

Although trading on DeltaDeFi is as easy as it seems, the design of this protocol is a combination of multiple design choices and research items. In this section, we will walk through the magic behind the scenes to bring the seamless trading experience on Cardano.

## What we cover

* [**Architecture**](/about/learn/architecture.md) — How DeltaDeFi works under the hood: accounts, the App Vault, Hydra integration, intent-based processing, and the order book.
* [**Trade**](/about/learn/trade.md) — Spot trading mechanics, performance specs, and supported order types.
* [**Whitepaper**](/about/learn/whitepaper.md) — The full technical whitepaper.
