1. Overview​

Tag Address is used to categorize and manage wallet addresses. When creating a payment order, merchants can specify tagName so the system automatically assigns a receiving address from the corresponding tagged address pool.

Address allocation rules:

  • If an available address exists under the tag, the system prioritizes reusing it.
  • If all addresses under the tag are occupied, the system automatically creates a new address.
  • The newly created address is automatically assigned to the same tag.

This mechanism helps merchants achieve:

  • Address categorization
  • Address reuse
  • Automatic address expansion

This mechanism is ideal for merchant scenarios that require managing a large number of receiving addresses.
