Verify the hash before signing

The final hash comparison is the reason to perform an independent transaction review.

The workflow

1. Load the transaction in Transaction Inspector.
2. Read every decoded action and confirm the recipient, asset, amount, function, and operation.
3. Find the recomputed SafeTxHash in the analysis.
4. Begin reviewing the same transaction in the signing wallet.
5. Compare the wallet's hash with the recomputed SafeTxHash character by character.
6. Check the beginning, middle, and end - not only the first few characters.
7. Sign only when the full values match and the decoded actions are approved.

                yes               no

                 |
          sign on the wallet

What a match proves

A match confirms that the transaction fingerprint shown by the wallet agrees with the independently recomputed transaction fingerprint.

It does not prove that:

• The recipient is trustworthy.
• The amount is appropriate.
• The transaction was authorized by governance.
• The decoded action is beneficial.
• Future chain state will match a simulation.

Always verify both: the hash matches and the decoded actions are correct.

Who should compare it?

Every owner should perform the comparison when signing. The final signer or executor should repeat it immediately before execution. In smaller teams this may be the same person, but the rule remains: whenever a signature is about to be produced, verify the hash first.
