COLDCARD RNG incident the public record, collected and explained
Informational only, and this site never asks for your seed words. details

Informational only. This is an open source collection of what others have published about the incident, together with an explanation of it. It is not financial, security or legal advice, and not a substitute for professional advice about your own situation. It is not affiliated with, endorsed by, or speaking for Coinkite. Material is attributed and quoted as published; where sources disagree their scenarios are kept separate with their assumptions rather than reconciled into one answer. Everything is meant to be checked against the linked evidence rather than taken on trust. Act on your own judgement about a particular situation. Editorial standards and corrections.

Do not disclose recovery material to a website, form, message or support account. This site never asks for it, and contributions containing recovery words or private keys are not accepted.

    ## 1.4.1Q - 2026-07-01
    - Enhancement: Can export WIF Store watch-only descriptor.
    - Enhancement: WIF Store address detection without the need
      for `PSBT_IN_BIP32_DERIVATION` (improves Electrum support)
    - Enhancement: BIP-322 Proof of Reserves and Message Signing PSBT
      requires `PSBT_GLOBAL_GENERIC_SIGNED_MESSAGE` field
      (read more [BIP-322 Proof of Reserves documentation](../docs/proof-of-reserves-bip-322.md) )
    - Bugfix: Fixes legacy input amount spoofing by rejecting witness-utxo-only
      PSBT inputs when Coldcard is expected to sign a non-segwit input.  When both
      UTXO fields are present the full `non_witness_utxo` is now preferred for
      amount/script lookup. Thanks, @Damir!
    - Bugfix: Keep NFC export tag alive for repeated probes. Helps NFC tap reliability on iOS.
    - Bugfix: Emit warning and do not calculate fee for legacy UTXOs with only witness utxo.
    - Bugfix: Disable Virtual Disk and NFC before activating HSM.
    - Bugfix: P2PK signing was broken. Now supports both compressed and uncompressed P2PK spend.
    - Bugfix: Custom address default menu position was wrong.
    - Bugfix: Delta Mode Trick PIN was never restored from backup.
    - Bugfix: Proper error message for incorrect 7z headers.
    - Bugfix: Exiting nickname entry with nickname already saved deleted previous nickname.
    - Bugfix: Incorrect error message caused by error in Verify/Decrypt Backup.
    - Bugfix: NFC Verify Address raised incorrect error message.
    - Bugfix: CCC key C challenge handled bad BIP-39 checksum by crashing the UX. Now treated
      as a wrong attempt (counts toward 3-strike lockout).
    - Bugfix: CCC magnitude reset from CANCEL on empty input.
    - Bugfix: `OP_RETURN` in CCC with whitelist enabled caused Yikes.
    - Bugfix: TX Explorer crashed on foreign input with non-standard sighash.
    - Bugfix: Malformed JSON message-sign request crashed signing UX.
    - Bugfix: Reject UI-control bytes in JSON / QR text message-signing.
    - Bugfix: Non-standard `OP_RETURN` outputs shown as "null-data", hiding part of the script.
    - Bugfix: Over-limit CCC address-whitelist import was rejected but still modified the policy.
    - Bugfix: Deleting a file right after renaming it (List Files) blanked the old name,
      leaving the renamed file.
    - Bugfix: Reordered `multi(...)` multisig with same keys was misreported as name-only
      change. Now blocked as duplicate.
    - Bugfix: Max WIF store capacity limit was ignored if saving via QR WIF visualization.
    - Bugfix: Force Seed XOR restore from Temporary Seed menu to remain temporary even when
      master seed is blank.
    - Bugfix: Binary signed-transaction (.txn) failed in NFC/QR file share.
    - Bugfix: Yikes in transaction explorer for goto index for tx with only one output.

How to check this yourself

The excerpts and plain unified diffs above show the text this project held and how it changed. To verify a quotation, compare it against the page itself or against the Internet Archive's copies, which are independent of this project.

Complete captures are held offline rather than mirrored here, so this page shows diffs and excerpts. If a quotation is ever disputed, the full copy can be produced. Ask.
