(MENAFN- EIN Presswire) EINPresswire/ -- Bull Bitcoin, a leading non-custodial Bitcoin exchange and OTC desk, has launched its wallet with official support for COLDCARD, an ultra-secure Bitcoin hardware wallet trusted by Bitcoiners worldwide.
This integration allows users to:
. Import a COLDCARD wallet via QR code (BBQr)

The partnership highlights the power of interoperability through open standards like PSBT, which enables Bitcoin software and hardware to work together seamlessly. It provides users with a secure and effortless experience – with no technical hurdles, no reliance on third parties, and no compromises.
“I've been searching for the most secure and seamless way to hold Bitcoin for the long term while also being able to use it day-to-day. It needed to be accessible to non-technical users, yet still provide the advanced functionality that seasoned Bitcoiners require. I believe that with the COLDCARD Q integration in the Bull Bitcoin wallet, we've achieved the greatest self-custody Bitcoin user experience the world has ever seen.” – Francis Pouliot, CEO of Bull Bitcoin
“I think Bitcoin companies working together on open standards and interoperability is how Bitcoin moves forward,” said NVK, co-founder of Coinkite.“COLDCARD and Bull Bitcoin are a match made in heaven.”, "Bitcoin the right way; Open standards, open access, vendor interoperability, with user unilateral exit."
With COLDCARD's robust security model and Bull Bitcoin's trust-minimized infrastructure, Bitcoiners now have an end-to-end solution for stacking and spending directly from cold storage – all built on the principles of self-custody, simplicity, and sovereignty.
