# Introduction

**StarKey Wallet** is a multi-vm crypto wallet that can be used to manage digital assets and access decentralized applications on [Supra](https://supra.com/), [Aptos](https://aptosfoundation.org/), [Ethereum](https://ethereum.org/en/), [Solana](https://solana.com/) and [Sui](https://sui.io/).

StarKey is currently available as:

* A [browser extension](https://chromewebstore.google.com/detail/starkey-wallet-the-offici/hcjhpkgbmechpabifbggldplacolbkoh)
* An [iOS app](https://apps.apple.com/us/app/starkey-wallet/id6636478764)
* An [Android app](https://play.google.com/store/apps/details?id=com.StarKey)

Developers can interact with Starkey via both **web** applications as well as **iOS** and **Android** applications.

To interact with web applications, the StarKey extension injects a `starkey` object into the JavaScript context of every site the user visits. A given web app may then interact with StarKey, and ask for the user's permission to perform transactions, through this injected provider.
