Bull Bitcoin Launches BULL Wallet: A Privacy-First Mobile Wallet Redefining Bitcoin Self-Custody on iOS

3 Key Points:

• Bull Bitcoin introduces BULL Wallet, a fully open-source, privacy-centric Bitcoin wallet now available globally on iOS and Android.

• Supports Lightning and Liquid Networks, enabling faster, more private Bitcoin transactions with deep exchange integration for optional fiat services.

• Built for both beginners and advanced users, featuring Payjoin privacy protocol, COLDCARD hardware support, and customizable security tools.

Bull Bitcoin Unveils Global iOS Launch of BULL Wallet

Bull Bitcoin, one of the leading privacy-focused Bitcoin-only exchanges, has announced the global availability of BULL Wallet, its new mobile wallet for iOS and Android users. The launch marks a significant milestone in the evolution of user-controlled digital finance, blending top-tier privacy, security, and accessibility for both newcomers and long-time Bitcoin maximalists.

According to founder Francis Pouliot, the project is “a gift to the Bitcoin network” — a culmination of years of development focused solely on empowering users to hold and transact Bitcoin without reliance on intermediaries.

“BULL Wallet is my passion project. It’s Bitcoin-only, fully open-source, and designed to prioritize privacy, security, and simplicity,” said Pouliot in a press statement shared with Bitcoin Magazine.

A Privacy-First Design for Everyday Bitcoin Use

At its core, BULL Wallet combines simplicity with deep privacy capabilities. It enables basic send and receive functions, integrates seamlessly with COLDCARD — one of the most secure hardware wallets — and offers support for the Lightning Network and Liquid Network, two of Bitcoin’s most powerful scaling and privacy solutions.

The wallet’s Payjoin integration is one of its standout features. Unlike conventional mixers, Payjoin allows two participants to make a joint transaction that obscures which party paid whom, improving transaction-level privacy without compromising usability. This subtle but powerful design enhances Bitcoin’s censorship resistance and network fungibility — key pillars of its decentralized ethos.

Unlike many competing wallets, BULL Wallet deliberately avoids unnecessary complexity, opting instead for user autonomy. Users can connect to their own nodes or Electrum servers for direct blockchain access, manage coin labeling and selection, and customize fee calculations to optimize transaction costs.

Built for Power Users, Ready for Mainstream

Under the hood, BULL Wallet runs on SegWit-native descriptor architecture and leverages the Bitcoin Development Kit (BDK) for robust reliability. It supports BIP39 mnemonics, BIP85 secret derivations, and watch-only wallet imports, all within a clean, ad-free environment.

Security is reinforced through encrypted data storage, a secure keyboard to prevent clipboard hijacking, and a strict no-data-collection policy. Importantly, all features are fully open-source, enabling transparency and community auditability.

The wallet also offers optional integration with Bull Bitcoin’s exchange, allowing users — depending on jurisdiction — to pay bills, buy and sell Bitcoin, and perform fiat conversions. However, these integrations remain strictly opt-in, preserving the wallet’s commitment to autonomy and privacy.

Strategic Positioning in the Self-Custody Era

BULL Wallet’s debut comes at a pivotal time for the crypto industry, as self-custody adoption accelerates amid regulatory crackdowns and exchange-related scandals. According to market data from Chainalysis, self-custody wallets have seen a 28% increase in user activity year-over-year, reflecting a clear shift toward control and transparency.

Bull Bitcoin’s strategy positions the wallet not just as a tool, but as an ideological statement: that Bitcoin should remain independent of corporate or governmental interference. For many in the Bitcoin community, tools like BULL Wallet represent a philosophical return to Satoshi Nakamoto’s original vision of financial sovereignty.

A Look Ahead: Roadmap and Future Development

The BULL Wallet team has outlined an ambitious roadmap, including multisignature support, Silent Payments, Ark Network integration, and Nostr-based anonymous messaging. The developers also plan to introduce fully reproducible builds, ensuring verifiable code integrity.

Pouliot confirmed the long-term vision: “This is only the beginning — we will keep improving it forever.”

As the wallet continues to evolve, its blend of cutting-edge privacy, open-source development, and strong philosophical grounding could make it one of the most influential Bitcoin-only mobile wallets of the decade. For users prioritizing independence in an increasingly centralized digital world, BULL Wallet may become the new standard for secure, private, and censorship-resistant Bitcoin use.
