BlueWallet: Bitcoin & Lightning Wallet for Any OS

BlueWallet is a user-friendly, open-source Bitcoin and Lightning Network wallet designed for mobile and desktop users. It provides secure, non-custodial access to both on-chain and off-chain Bitcoin transactions, appealing to beginners, advanced users, and Bitcoin maximalists alike. Available on iOS, Android, and through a web interface or progressive web app (PWA), it offers flexible access on virtually any operating system.

Bitcoin Wallet (On-Chain)

BlueWallet supports native SegWit (bech32), wrapped SegWit, and legacy Bitcoin address formats, ensuring compatibility with different platforms and services. It follows a hierarchical deterministic (HD) wallet model, allowing users to back up and restore their wallets using a 12- or 24-word seed phrase.

Users retain full control of their private keys, which are stored locally on their devices. Features include Replace-by-Fee (RBF), custom transaction fees, coin control, batch transactions, transaction labeling, and watch-only wallet support. These advanced tools make BlueWallet suitable for both everyday users and Bitcoin professionals.

Lightning Wallet

BlueWallet offers built-in Lightning Network support, enabling fast, low-fee Bitcoin transactions. There are two main options for using Lightning:

1. Custodial Lightning Wallet – Quick to set up and use, this option relies on BlueWallet’s default LNDHub instance to manage the user's Lightning funds. It’s ideal for beginners and those seeking convenience, though users don’t control the underlying node.
2. Non-Custodial (External Node) – Advanced users can connect their own Lightning node (via LNDHub, Umbrel, or BTCPay Server), retaining full custody of their funds and channel management. This integration empowers users to use Lightning while maintaining sovereignty over their setup.

Cross-Platform Support

BlueWallet is available on iOS and Android through their respective app stores. While there’s no traditional desktop application, it functions well on desktops through its progressive web app and by connecting to remote LNDHub instances. This cross-platform approach allows users to manage their funds across all major operating systems.

Backups are supported via BIP39 seed phrases, making the wallet interoperable with other HD wallets like Electrum.

Privacy and Security

BlueWallet is non-custodial by design, meaning users have full control over their private keys. It does not require user identification or KYC, enhancing user privacy. The app also includes features like biometric authentication, PIN protection, plausible deniability (via decoy wallets), offline signing via PSBT (Partially Signed Bitcoin Transactions), and QR code-based communication to keep sensitive data secure.

Developer and Power User Features

The wallet is open-source, encouraging transparency and community contributions. It supports multisignature vaults, import of xpub/ypub/zpub keys, and integration with hardware wallets such as Coldcard. Developers can also experiment with LNDHub to set up custom Lightning backend solutions.

Summary

BlueWallet is a powerful, easy-to-use Bitcoin and Lightning wallet that supports mobile-first usage while maintaining high security and privacy standards. With advanced features like Lightning integration, PSBT support, and multisig vaults, it’s well-suited for a wide range of users—from casual holders to hardcore Bitcoiners managing their own nodes. While it only supports Bitcoin and not other cryptocurrencies, its clean design, open-source nature, and robust feature set make it one of the leading wallets in the Bitcoin ecosystem.
