Persisted transaction {tx_hash} does not match the signed by

Error message

Persisted transaction {tx_hash} does not match the signed bytes

What it means

Integrity check after persisting a signed transaction: reopening the stored envelope yields bytes that differ from the signed transaction, meaning the persisted record is not the signed payload and must not be broadcast.

Solutions

1. Re-sign and re-persist the transaction
2. Investigate envelope sealing / payload-key configuration for the mismatch
