# Introduction

## What is UNION?

UNION is a technology platform that combines bundled protection and a liquid secondary market with a multi-token model. With UNION, DeFi participants manage their multi-layer risks across smart contracts and protocols in one scalable system.  UNION’s full-stack DeFi protection is inclusive, composable, and brings battle-tested capital and pricing models from TradFi to the DeFi ecosystem.

The UNION Protocol repository can be found [on Github here](https://github.com/UNIONProtocolFoundation).
