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:

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

I've been using this wallet daily since the early beta. It keeps getting better and better with each release. Hands down the absolute best bitcoin wallet I've ever used.

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.

Terrible app and even worse customer service. My funds were unavailable to me for 2 weeks and I had to put in 8 hours of work just to get my money back to my account because they aren't clear about which of your bank accounts can send money to the account. Fitting name to call it Bull bitcoin since it's actually bullsh*t. Avoid If you value your time and sanity.
