About this app

Bull Bitcoin Mobile is a self-custodial wallet for Bitcoin and the Liquid Network. It integrates atomic swaps across Bitcoin, Lightning, and Liquid. Rooted in cypherpunk principles, it prioritizes user sovereignty, open-source transparency, and trustless operation. The wallet blends advanced features with intuitive design, ensuring easy access and full control for all users.
We empower users to custody their bitcoin, even in high-fee environments. Our design promotes best practices for simple, secure, and efficient Bitcoin self-custody.
Key features include:
Full Control: Users hold sole authority over their funds. Developers cannot access, censor, or freeze assets.
Lightning Network: Send and receive instant, low-cost payments via Lightning.
Liquid Network: Enhances low-cost transactions with good privacy.
Open-Source: Fully verifiable and auditable code, eliminating hidden risks (MIT license).
Smart Fees: minimize bitcoin transaction costs at all times.
The app creates two wallets from one seed, requiring only a single backup:
Instant Payments Wallet: A Liquid-based wallet for daily Lightning payments. It’s user-friendly, self-custodial, and avoids complex channel management issues.
Secure Bitcoin Wallet: A descriptor-based wallet for long-term savings and daily use, for maximum interoperability, and no lock-in. It supports Lightning and advanced security features.
Bull Bitcoin Mobile offers a swift, reliable, and intuitive experience for all Bitcoiners with no compromises, enabling more individuals to become sovereign with the world’s best money.

Ratings and reviews

Works great! Might take 2 or 3 seconds longer to confirm a lightning transaction than other wallets. Hang on to your seed words in case they update the wallet on you. The Bull Bitcoin team is the best in the world for Bitcoin stuff. No joke. I highly recommend all of the Bull Bitcoin ecosystem. Install this wallet!😀

Bull is an excellent app, it's great way to use layer 2 and on chain in a unified way. you can even use a signer and import an xpub if you wish. Support are super helpful too.

one of the best apps on the market, and impeccable customer service.
