Ledger CEO Pascal Gauthier said hardware wallet security should be engineered to withstand user mistakes rather than shifting more responsibility onto customers, arguing that "total safety" does not exist and that self-custody (holding crypto without an intermediary) will remain limited if ordinary users are expected to understand every technical failure mode. His comments came after a series of incidents in the hardware wallet market, including Coinkite's July 30 warning that some Coldcard-generated Bitcoin wallets may be vulnerable because of an entropy problem (weak randomness in key creation) during seed generation (creating the recovery phrase), with losses already above 1,000 BTC by July 31. Galaxy Research said on August 4 it had identified 1,596 BTC stolen from 7,300 addresses. Gauthier said discipline cannot compensate for flawed design and added that users should not simply accept manufacturers' security claims, writing, "And no one's design should be taken on their word, ours included," while framing security as a continuous process of testing and improvement.
