# Introduction

**Jelli** is a crypto wallet that can be used to manage digital assets and access decentralized applications on Solana, Bitcoin, Ethereum, and other supported networks.

Jelli is currently available as:

* A browser extension
* An iOS app
* An Android app

At its core, Jelli works by creating and managing private keys on behalf of its users. These keys are securely stored and used within Jelli to hold funds and sign transactions.

Users can interact with Jelli through both **web applications** and **iOS/Android** mobile apps.

To interact with web applications, the Jelli **extension** and **mobile in-app browser** inject a `jelli` object into the JavaScript context of every site the user visits. A web app may use this object to connect with Jelli, request the user’s permission, and initiate transactions — all through the injected provider.

It’s also possible to interact with the Jelli mobile app using **universal links and deep links**. These allow mobile apps and dapps to prompt users to connect, sign, and send with Jelli directly. Once the action is completed, Jelli will return the user to the originating app.

This documentation is intended for developers building applications with Jelli. If you’re looking to integrate Jelli into your app, check out our developer documentation or visit our GitHub. For help, feel free to reach out through our Help Center.
