info

Please note that this content is under development and is not ready for implementation. This status message will be updated as content development progresses.

Description

The processTransactionEvent service is responsible for processing a Transaction Event (DTE), issuing a Verifiable Credential (VC), uploading it to the Storage service, registering the link to the stored DTE with the Identity Resolver service, and managing DPPs in local storage associated with the event. It handles the entire lifecycle of creating and managing a transaction event, from data input to storage, resolution, and local data management.
