Two Canadian Bitcoin pioneers are joining forces to take Bitcoin self-custody to the next level.

Bull Bitcoin, founded in Montreal in 2013 has partnered with Coinkite, the Toronto-based maker of the iconic COLDCARD hardware wallet.

This partnership introduces full COLDCARD Q support within the BULL Wallet, allowing users to buy Bitcoin directly into cold storage and spend securely using PSBT. Users never expose private keys and do not need to trust a third party.

This integration is more than technical; It is a natural alliance between our two Canadian-born companies, built by and for Bitcoiners. Both share the same mission: sovereignty, open standards, and uncompromising Bitcoin-only principles.

A Canadian Alliance Rooted in Cypherpunk Philosophy

Bull Bitcoin and Coinkite are part of the vibrant Canadian Bitcoin ecosystem, which has fostered many respected Bitcoin engineers, educators, and builders.

Our companies represent a shared legacy of independence, transparency, and deep respect for Bitcoin’s original ethos: empowering individuals through self-custody.

I think Bitcoin companies working on open standards and interoperability with open standards is how Bitcoin moves forward. COLDCARD and Bull Bitcoin are a match made in heaven. - NVK, Coinkite’s co-founder.

From Zero to Sovereign in Five Minutes

With this integration, Bull Bitcoin and Coinkite are delivering what Francis Pouliot, founder of Bull Bitcoin, calls:

The ULTIMATE Bitcoin self-custody experience.

In a tweet that quickly went viral, Francis Pouliot walked us through the entire process, from setup to automated cold storage DCA using Bull Bitcoin Exchange:

Note: You can link your Bull Bitcoin Exchange account to the BULL Wallet if you are in a jurisdiction where Bull Bitcoin Exchange operates. However, the BULL Wallet is free and open-source and available worldwide on both iOS and Android. Read more here.

The result is a fully automated, non-custodial Bitcoin stacking setup. Users avoid manual address entry, small UTXOs, and any chain link to their KYC account. They have pure Bitcoin held entirely by themselves.

Built on Open Standards

This partnership demonstrates how Bitcoin innovation should be done: through collaboration on open protocols, not proprietary silos.

The integration is fully non-custodial and standards-based. Users can:

• Import their COLDCARD Q via QR code in seconds

• Buy Bitcoin directly to cold storage

• Spend securely using PSBT, with no cables and no exposure

Every step uses open Bitcoin standards, ensuring total user control and interoperability across the ecosystem.

Building the Future of Bitcoin We Want to Use

This partnership is about more than convenience. It is about principle: sovereignty without compromise.

By combining Bull Bitcoin’s trust-minimized infrastructure with Coinkite’s hardware, users can now move seamlessly from fiat to cold storage securely, privately, and efficiently.

There are no centralized custodians, no compromises. Users hold Bitcoin exactly as it should be.
