After two years of tireless work, the BULL wallet is now available worldwide on iOS as well as Android. Yes, this includes the USA!

BULL is a mobile app focused on privacy, security and usability for day-to-day Bitcoin transactions. It was designed to satisfy the high standards of the most hardcore cypherpunk Bitcoin OGs, while simultaneously being incredibly easy to use for beginners. It is self-custodial, Bitcoin-only, fully open-source and does not require any KYC to use.

It does everything you’d expect it to do: send and receive Bitcoin payments. No clutter. No noise. Just a high-performance, beautifully designed wallet. 

Transact seamlessly on the Bitcoin Network, Lightning Network and Liquid Network. Using non-custodial atomic-swap technologies, you can move funds between networks confidentially and securely.

Connect your Bull Bitcoin account to buy bitcoin, sell bitcoin and make fiat payments directly with your self-custodial wallet. No insecure and stressful copy-pasting of addresses between different apps. This is optional, and you don't have to link an account if you don't want to. But doing so is a magical experience: so easy, it feels like using a custodial exchange!

Avoid High Network Fees

Customizable mempool-based fee calculations and RBF technologies ensure you never overpay Bitcoin mining fees. Receive small payments in your Liquid Network wallet that are automatically swapped for a secure Bitcoin wallet once you reach a customizable threshold, avoiding small UTXOs. Lightning payments are done without liquidity and channel management. Send and receive Lightning payments seamlessly with one click, without paying for channels open transactions.

Privacy-First Approach

No KYC email or phone required, no data collection, no push notifications, no IP tracking. Maintain self-sovereignty by connecting to your own Electrum server for direct access to the Bitcoin network. Create collaborative Payjoin transactions to mitigate on-chain spying of your wallet activity. Smart labeling and coin control help you protect your privacy. The Liquid Network’s Confidential Transactions hide the amount and asset type of your transactions.

Hardware Wallet Companions

BULL is designed to serve as a mobile companion app for your hardware wallet. Import watch-only wallets to monitor your cold storage accounts and receive funds into your hardware wallets. Connect your Coldcard Q to securely spend funds from cold storage via air gapped signing, no SD card or cables required! BULL plans to support all major hardware devices, including the Blockstream Jade that is compatible with the Liquid Network.

What's Next?

BULL is fully funded by Bull Bitcoin for continuous development for the long term. Our goal is to keep adding features to not only match the level of flexibility you get from desktop wallets such as Electrum or Sparrow, but also to implement bleeding-edge technologies to scale and improve the Bitcoin user experience.

Here is a preview of what we are working on:

  • Ark network integration
  • Silent Payments 
  • Secure and unlinkable metadata backups
  • Advanced coin labeling and selection
  • All major hardware wallets
  • Multi-signature wallets and Miniscript
  • Nostr-based chat 
  • LN addresses 

This is only the beginning. We now have a solid foundation for a mind-blowing Bitcoin wallet that is secure, private and easy to use. But we will not stop here, far from it.
