Hardware Wallet Sales Spike Amid Coldcard Crisis

Hardware wallet manufacturers have seen a surge in sales following the Coldcard crisis. Trezor, Onekey, and Bitbox confirmed their sales jumped in August, with Bitbox's credit-card sales increasing roughly tenfold compared to the baseline.

Trezor's Head of Security, Jan Komárek, pointed out that this spike is an encouraging sign for the Bitcoin industry, as people affected by the Coldcard situation went looking for another hardware wallet rather than giving up on self-custody.

However, according to industry analysts, many hardware wallet users sent their funds to crypto exchanges or moved their capital to ETFs, abandoning self-custody. Onekey noted that its sales increase might also have been affected by other factors, including individual product cycles.

The Coldcard crisis has prompted teams to review their current security models and implement changes. Trezor is adding further sanity checks on the device's own internally generated entropy, while Bitbox took another detailed look at its random number generator code. Onekey conducted an additional end-to-end verification of the entropy and seed-generation paths across its hardware wallet lineup.
