Bull Bitcoin, the privacy-focused international bitcoin exchange, has just announced the global release of BULL Wallet on iOS. The mobile app is designed for both beginners and hardcore cypherpunk Bitcoin OGs. Available now on iOS and Android, BULL Wallet optimizes “high-level privacy, security and usability for everyday Bitcoin transactions and long-term secure cold storage,” according to a press release shared with Bitcoin Magazine.
“BULL Wallet is my passion project and a gift to the Bitcoin network. It’s just Bitcoin, completely open source and built to prioritize privacy, security and simplicity,” Pouliot said of the wallet, which is completely open source and ad-free.
The BULL bitcoin wallet is full-featured and offers a wide range of functionality, starting from basic sending, receiving and accounting, to hardware wallet support via COLDCARD integration, generally considered the most paranoid and advanced hardware wallet. In between, the wallet makes a series of opinionated design choices that optimize bitcoin privacy while avoiding the high levels of complexity found in other popular bitcoin mobile wallets today.
Of course, as is the company’s branding, the wallet is bitcoin-only, though it supports the leading crypto asset in both the Lightning Network and Liquid Network, giving users great options for both privacy, long-term custody, and transaction speed. The wallet also has a built-in swap exchange using a powerful technology called atomic swap, which allows users to move from one layer of bitcoin to another without having to trust any exchange with their funds during the transition, unlike regular centralized exchanges or even popular exchanges or “instant exchanges.”
The BULL Wallet also has deep integration with the Bull Bitcoin exchange, a crucial feature for the long-term sustainability of mobile wallets, which otherwise tend to struggle to find a business model and thus stay afloat. Exchange interactions are opt-in and can be ignored entirely, but if enabled, they can unlock extra features such as fiat bill payments, quick purchases, and bitcoin sales, among other features, depending on the jurisdiction.
One of the coolest features offered by the BULL Wallet is the seamless integration with Payjoin, a privacy protocol that, unlike popular coin mixers, doesn’t take much time or require a third party to help coordinate. Instead, if both the sender and recipient support the protocol, the payjoin transaction occurs, making it harder for data analytics companies to know who paid how much to whom. Payjoin transactions look like normal transactions, but they simply organize money flows in a private manner, resulting in a measurable improvement in user privacy, something that is also generally positive for Bitcoin’s censorship-resistant qualities.
The BULL Wallet has a long list of features that advanced users will appreciate, while new users will simply be able to take advantage of, such as;
- Segwit native descriptor-based architecture using the trusted BDK library
- Standard BIP39 mnemonic support
- Connect to personal nodes or your own Electrum server for direct access to the Bitcoin network
- Coin sorting and labeling functionality
- Customizable mempool-based fee calculations with RBF to avoid overpaying mining fees
- Wallet import for watch only
- Encrypted secrets to protect against malicious apps
- Secure keyboard to prevent clipboard hijacking
- No push notifications and no data collection
- Address labeling for better coin sorting
- Secret derivation based on BIP85
- Support for multiple fiat currencies
- Test network compatibility
Future roadmap
The team, made up of four full-time developers and “lifetime funding,” has a profound roadmap ahead of them that, if completed, could lead to the creation of the most powerful Bitcoin-only mobile wallet in the industry. Some of these milestones include:
- Fully playable builds
- Integration of the Arca network
- Silent payments
- Secure and anonymous metadata backups
- Advanced coin labeling and sorting
- Support for all major hardware wallets
- Multi-signature wallets and Miniscript
- Anonymous chat based on Nostr
- LN addresses
Francis, an entrepreneur with deep experience in the Bitcoin industry, said of the roadmap that “this is just the beginning, we will continue to improve it forever.”
