# Introduction

Cryptonauts is a UE5 multiplayer GameFi Experience built on UE5 and powered by **Stacks**, a Bitcoin-anchored smart contract layer. \
\
This documentation details how we integrated Stacks wallet authentication, NFT verification, and on-chain asset logic directly into Unreal Engine, enabling features such as player skin ownership validation, Codex Component loadouts (NFT-based abilities), and signed game session data for Web3 interoperability. \
\
The goal of this documentation is to help other Unreal developers understand how to bridge traditional multiplayer systems with verifiable on-chain data, using the Stacks blockchain.\ <br>
