Coldcard Theft Victims Face Uphill Legal Battle, Crypto GCs Say

More than $100 million in bitcoin has been drained from Coldcard hardware wallets, and the theft has pushed a question crypto long avoided into the open. Three crypto general counsels, speaking on the DEX in the City podcast, said victims who followed every self-custody precaution may still have no clear path to sue. Product-liability law, the natural fit, does not stretch easily to a firmware flaw.

The exploit traces to a 2021 Coldcard firmware bug that generated wallet seed phrases with too little randomness. The output was predictable enough for attackers to reconstruct private keys across thousands of wallets. On-chain analysis from Galaxy Research identified 1,367 BTC taken from 4,585 addresses. New attacks kept surfacing, and the total climbed past $100 million.

What makes the episode a legal puzzle, the hosts argued, is that the victims did exactly what the industry preaches. Vy Le, general counsel of Veda, said the hardest part is that owners believed they had retired the risk of holding their own crypto, then lost it anyway. The lesson, she argued, is that owning your own keys never erased the need to trust someone.

Self-custody, she said, "doesn't completely eliminate trust." Owners no longer trust a centralized custodian, Le said; they trust the device's makers. "You're trusting the engineers who designed the hardware and the firmware that generated your keys. You're trusting the people who reviewed the code, the auditors."

The reframing pushes the incident from a security story into a legal one. The hosts asked whether someone who did everything right and still lost their coins can sue anyone. "What duty does a hardware wallet manufacturer owe to its users?" Le asked on the show, running through the possible theories: negligence, product liability, consumer protection law, breach of warranty.

Software Bugs vs. Product Defects in the Coldcard Case

Product liability is the instinctive claim, the hosts agreed; it is the body of law covering goods that are defectively designed or sold without adequate warnings. The weakness in the Coldcard case lives in code, not casing, and that kind of flaw has surfaced in other devices before without producing a clear legal remedy.

Katherine Kirkpatrick Bos, a co-host and longtime crypto general counsel, said no precedent addresses how this works in cryptography. "Courts have not consistently treated software bugs as product defects," she said. "They're not treated the same as physical defects. So it's actually an uphill battle to even sue on the basis of product's liability." She added that the theory would be the natural instinct for any litigator representing a victim.
