BlueWallet CTO Flags 45 of 494 iOS Crypto Wallets Over Security Risks

BlueWallet’s chief technology officer screened 904 iOS apps listed on the App Store as non-custodial crypto wallets, analyzed 494 of them and flagged 45 as having potential severe or high security risks, including 23 rated potentially critical and 22 high risk. The issues cited include suspected uploads of mnemonics or private keys to servers, weak wallet randomness, server-side key storage, hardcoded encryption keys and loading of unsigned JavaScript that can interact with sensitive wallet data. The CTO noted the findings may include false positives and that apps absent from the list are not necessarily safe.

AI take

The striking part is not the count but the failure modes: mnemonic exfiltration, weak randomness and unsigned JavaScript are exactly the classes of flaw that turn a self-custody wallet into a custodial one without the user noticing. For anyone treating App Store listing as a proxy for safety, this undercuts that assumption, and the CTO's own caveats — false positives possible, unlisted apps not cleared — mean the list is a starting point rather than a verdict. Whether independent reviewers reproduce or dispute these findings is the open question.
