# Introduction

> Explore our JS SDK for building applications with Lit Protocol

<Tip>
  Lit V1 ("Naga") is currently live on [testnet](https://spark.litprotocol.com/naga-test/).

  If you're a builder looking to deploy your application in production, you can use Lit's V0 Mainnet Beta ("Datil"), already live today ([Link](https://developer.litprotocol.com/)).
