2. Sequence diagrams

1) Login

Login Simple Sequence Diagram
  • To log in by looking up the game player ID, the Points Exchange Center provides the same authentication channel as the authentication in the game, and issues a login token using the information passed by authenticating through each channel.
  • The Points Exchange uses tokens issued by the game certifier for protected support requests.

2) Withdrawing points (depositing tokens)

Point Withdrawal Simple Sequence Diagram
  • If the request to deduct points from the game server is successful, a token deposit request is made to the TX-SERVER to a specific wallet address, and the result is checked using the request information in a later callback.
  • TICKET_IDs for TX-SERVER requests are generated, requested, and stored as unique, non-duplicated information.

3) Deposit points (withdraw tokens)
