BlueWallet

BlueWallet is an open-source Bitcoin wallet (MIT license) built on ReactNative with a blend of top-tier security and user-friendly features. Store, send, receive, and buy BTC directly in the app. Private keys are always stored locally on your device. Available for Android.

Security Features

Your keys are protected by multi-layer encryption with a password-based security. The Plausible Deniability feature lets you create a decoy wallet for emergencies. Hardware wallet integration (Ledger, Trezor) allows for cold storage. Advanced users can connect an Electrum server for enhanced privacy via a full node. Full Encryption ensures your data is securely protected, with extra layers of security and password-based encryption for all wallet activities.

Control Over Your Keys: With BlueWallet, your private keys never leave your device, ensuring you remain in control at all times.

Powerful for Everyday Use

The Lightning Network provides instant payments with commissions of less than a cent—ideal for daily transfers. The Local Trader service allows you to buy and sell BTC directly with other users without middlemen and hidden commissions.

Customize commissions manually: from 1 satoshi per byte to save money to higher rates for urgent transactions. If the transfer hangs, use Replace-By-Fee (BIP125)—change the commission or even the recipient's address without creating a new transaction. Watch-only wallets allow you to monitor your cold storage balance without the risk of hacking.

Simplicity

Create an unlimited number of wallets in seconds: SegWit, Taproot, or Legacy—choose the address format that suits your needs. Import existing wallets via seed phrases, private keys, or QR codes. The interface is available in different languages, and built-in hints will help beginners get used to it. Open source code allows you to verify security and suggest improvements, thus making BlueWallet the most transparent solution.
