## What it is
Backpack is an open-source crypto wallet browser extension built in TypeScript, serving as a home for xNFTs and supporting Solana, Ethereum, and Bitcoin. It is developed by coral-xyz and is under active development with APIs subject to change.

## Use cases
- manage a self-custody crypto wallet in the browser
- store and view xNFTs
- interact with Solana dapps from a browser extension
- sign blockchain transactions securely
- develop and test a crypto wallet extension locally
- hold multiple chains like Solana, Ethereum, and BTC in one wallet

## When to choose
- you need an open-source, self-custody browser wallet for Solana and other chains
- you want to experiment with xNFTs
- you are a developer contributing to or building on a wallet extension codebase

## When to avoid
- you need a production-audited wallet for large holdings (the code is explicitly unaudited)
- you need a stable API for integration (APIs are subject to change)
- you need a mobile-first wallet (this repo is primarily a browser extension)
