Expand description

Use Case: Initiate Payment

Initiates a payment transaction for article access. This creates a pending transaction that will be confirmed after on-chain verification.

Responsibilities:

  • Validate input (DTO validation)
  • Verify article exists and is purchasable
  • Verify creator can receive payments
  • Check for duplicate transaction signature (prevent replay attacks)
  • Create domain Transaction entity
  • Persist via repository
  • Return response DTO
