There is a request to classify transfers based on the data field when the source_event of the transfer is Unlock.
When a transfer is executed by an Unlock event, the data field contains information indicating the classification of the unlock.
We want to store this information from the data field in the database and return it via the API.
Describe the solution you'd like
