ZachXBT, one of the crypto industry's most prominent onchain investigators, said he does not consider current hardware wallets suitable for signing critical transactions or storing large amounts of assets. He singled out Ledger, one of the world's largest hardware-wallet makers, saying frequent Ledger Live updates often disrupt basic functionality, and floated a dedicated iPhone used solely for crypto management as a stronger alternative.
Why it matters
ZachXBT has built his audience tracking social-engineering scams, address-poisoning attacks, and drainers that walk victims through signing malicious transactions. His scepticism lands differently than a generic hardware-wallet critique: he is flagging the user-experience surface, firmware churn, and the blind signing workflow itself, rather than the secure-element hardware underneath. A dedicated offline iPhone running a minimal signing app shifts the trust assumption from a vendor-controlled firmware pipeline to a sandboxed consumer device the user controls end-to-end.
Market impact
For Ledger, the comments hit the brand more than the unit economics: most retail buyers default to the company's name without comparing alternatives. Watch whether other investigators publicly echo the take and whether Ledger responds with a firmware-pace clarification, since trust signals in self-custody compound slowly and erode quickly.
Frequently asked questions
-
What did ZachXBT actually say about hardware wallets?
He said current hardware wallets are not suitable for signing critical transactions or storing large amounts of assets, singled out Ledger over frequent Ledger Live updates that disrupt basic functionality, and suggested a dedicated iPhone used only for crypto could be a better alternative.
-
Why does ZachXBT's critique carry weight?
ZachXBT built his following investigating social-engineering scams, address-poisoning attacks, and drainer exploits, so his scepticism targets the user-experience surface and blind-signing workflow rather than the secure-element hardware underneath.
-
Is a dedicated iPhone actually safer than a hardware wallet?
ZachXBT argues the trust model is different. A sandboxed offline iPhone the user controls end-to-end removes vendor-controlled firmware churn and the disruptive update cycle he blames on Ledger Live, though it shifts risk rather than eliminating it.
-
How could this affect Ledger's business?
The comments hit the brand more than near-term unit economics, since most retail buyers default to Ledger without comparing alternatives. Watch whether other investigators publicly echo the take and whether Ledger responds with a firmware-pace clarification.
-
What should hardware-wallet owners actually do?
Verify every transaction detail on-device before signing, avoid blind signing, keep firmware updated, and consider splitting holdings across devices or wallets so a single point of compromise does not expose the full balance.
