# Transactions

In order to finish adding the hardware wallet as stake pool owner, the 3 certificates created earlier must be submitted to the blockchain with transactions. Because of a limitation of the hardware wallet firmware, for the moment a stake pool registration certificate must be sent alone in a transaction, so 2 transactions are required to submit the 3 certificates.
