BlueWallet

BlueWallet is a non-custodial, open-source wallet developed specifically for the Bitcoin ecosystem. Launched in 2017 by a small independent team—including Igor Kosakov, Nuno Coelho, and Marcos Rodriguez—BlueWallet has built a reputation for combining user-friendly design with advanced privacy and technical features. It is available on both mobile and desktop platforms, offering a comprehensive suite of tools for on-chain and Lightning Network Bitcoin transactions.

Unlike general-purpose multi-asset wallets, BlueWallet is Bitcoin-exclusive. This focused design allows it to deliver better performance, deeper protocol integration, and security standards aligned specifically with the Bitcoin network. The wallet is open-source under the MIT license, and the project maintains a strong emphasis on user sovereignty and transparent development.

Bitcoin-Only Architecture

BlueWallet supports the full spectrum of Bitcoin transaction types, including legacy, SegWit, and native SegWit addresses (BIP39, BIP49, BIP84). It is compatible with both hot wallets and watch-only wallets, allowing users to monitor balances securely from offline devices.

Lightning Network Support

The wallet integrates Lightning Network functionality in two ways: users can create self-hosted Lightning wallets by connecting their own LND node or use custodial Lightning wallets through the LNDhub protocol. LNDhub is an open-source service also developed by the BlueWallet team, enabling users to host their own Lightning backend if desired. This approach gives users maximum flexibility and choice in balancing security with usability.

Multisignature Vaults and Advanced Privacy

BlueWallet supports multisignature (multisig) wallets that allow funds to be secured using multiple private keys. These setups are ideal for institutional users, collaborative custody, or individuals seeking enhanced security. Users can define their own M-of-N signing policies and manage each signer across different devices or hardware wallets.

In addition to multisig, BlueWallet offers watch-only wallet capabilities. Users can import an extended public key (xpub) to monitor transactions and balances without risking exposure of private keys.

Privacy-focused features include:

• Tor routing (via system-level settings)

• Custom Electrum server support

• Plausible deniability mode, where decoy wallets can be created using additional passphrases

• Manual fee selection and UTXO management

Hardware Wallet Integration

While BlueWallet does not directly connect to hardware wallets via USB, it supports air-gapped signing workflows using PSBT (Partially Signed Bitcoin Transactions) and QR codes. This is particularly useful for Coldcard users and other hardware devices that support PSBT. Watch-only setups for Trezor, Ledger, and other wallets are also supported.

Developer and Power User Tools

For more advanced users, BlueWallet includes testnet support, Electrum server configuration, full access to wallet descriptors, and integration options for backend nodes. The app’s commitment to technical transparency and configuration flexibility has made it a popular choice for developers, educators, and Bitcoin power users.
