Coldcard and Trezor hardware wallets showing support for SLIP39 and BIP85 standards.

A growing coalition of users is advocating for Coldcard and Trezor to enhance their hardware wallet functionalities by integrating vital standards. This appeal arises amid concerns about technology compatibility and user expectations as of February 14, 2026.

The Case for Better Compatibility

Crypto enthusiasts are urging Coldcard to support SLIP39 and Trezor to adopt BIP85. They believe products from Coinkite and Satoshi Labs are among the best in the market, but current features fall short of user needs.

"It’s a sincere wish for better compatibility between these two brands," one user noted.

Mixed Reactions from the Community

The dialogue on forums showcases both confusion and emotional reactions. Main points of discussion include:

  1. Demand for Enhanced Features: "I consider the CCC to be equivalent or even superior to SSS. You don't need a special dictionary to implement a single-user multi-sig," stated a contributor.

  2. Critique of Company Attitudes: Another voice expressed frustration, observing, "There is no reason, just defiance/hate/ignorance from the side of Coinkite, I guess. Really a shame."

  3. Confusion Regarding Company Directions: Users shared uncertainty, asking, "Sorry for my ignorance, but what is the reasoning not to?" pointing to a struggle to understand the resistance.

Stakes for Hardware Wallets

Users' push for these standards raises questions about future hardware wallet reliability. Will the hesitation of these companies cost them user trust?

Key Insights

  • ⭐ Users demand Coldcard integrate SLIP39 support.

  • πŸ”’ The need for Trezor to adopt BIP85 remains urgent.

  • πŸ’¬ Frustration simmers as doubts about company intentions grow.

Looking Ahead

The pressure from dedicated users could lead hardware manufacturers to adapt. Estimates suggest a strong potential for increased user trustβ€”between 60% to 70%β€”if Coldcard and Trezor act. However, slow responses may push users towards alternative wallets, risking substantial sales declines. Experts warn that up to 40% of users might switch if their issues aren’t addressed within a year.

Parallels in Technology Evolution

The situation mirrors past tech shifts, like Apple’s transition from Lightning to USB-C. At first, there was resistance, but ultimately, the decision enhanced compatibility and user confidence. Just as Apple adapted, so too must hardware wallet makers consider embracing community-driven demands to ensure loyalty in a competitive market.

In this shifting landscape, companies must decide if they want to lead the charge or be left behind.
