OpenColdcard / Bitcoin wallet app Support Topics
Coldcard troubleshooting is safest when you separate setup source, app pairing, account display, firmware state, and recovery phrase concerns before changing wallet settings.
Coldcard Troubleshooting Checks
Use these checks to separate ordinary setup friction from wallet safety risk before you reset, restore, reinstall, or open wallet support portals.
PSBT direction
Separate unsigned PSBT export, Coldcard signing, signed PSBT import, and Bitcoin broadcast. Importing the wrong file makes signing look broken.
SD card handling
Card format, file location, filename, adapter reliability, and stale files can all interrupt an air-gapped signing or firmware workflow.
Bitcoin wallet context
Missing balances can come from xpub, script type, derivation path, account index, gap limit, wallet sync, or passphrase context.
Firmware source
Use verified official Coldcard firmware paths. Fake downloads and support pages may ask for seed words to complete a fake update.
Recovery phrase handling
Keep seed words offline and private. Do not photograph them, paste them into support, or use a validation page from an ad or message.
Transaction review
Read the Coldcard screen before signing. Reject unexpected destination, fee, coin selection, change address, or account context.
Coldcard Official Support Checklist
For official Coldcard help, downloads, updates, or contact options, use Coldcard's official portal and verified official channels. This page helps you prepare safe, non-private context before opening support portals.
Coldcard Recovery Phrase Safety
No legitimate Coldcard support should need your recovery phrase.
A recovery phrase controls wallet restoration. Treat it as private self-custody information and review how phrases work before using any wallet.

Describe Your Wallet Problem
Submit a non-secret wallet problem for moderated review and safer routing. PhraseWallet is independent and this is not official wallet support or emergency recovery assistance.
