How do I know whether a transaction problem is on-chain or inside the platform?

If a transaction hash exists, check it on the correct blockchain explorer. No hash can indicate the platform has not yet broadcast the transaction. For bank transfers, use the platform’s processing status and stated time window instead.

What should I include in a support case?

Use non-secret details: exact error, time, app/browser version, transaction hash or case reference if relevant, and a redacted screenshot. Never include passwords, one-time codes, private keys, seed phrases, or recovery phrases.

Is this guide financial advice or an official Trezor service?

No. It is an independent educational troubleshooting resource. It does not provide investment advice and does not access, verify, unlock, or recover Trezor accounts or wallets.
