• Start/Bid Auction --> add coinType (in case if we add other currencies in the future)
• Purchase name --> add coinType (in case if we add other currencies in the future)
• Renew Subname -->
  • expiration → distinguish between parent and custom
  • expirationDate → the real rexpiration time
• Create subname --> update properties so we have 2 event names: subname & parentName where the parent is the whole parent, which could be a subdame in itself like subname: lala, parent: lala.lala.tooling
• Combine connected address and set address as displayed in 1 which is connected address: properties:
  • name
  • addressType → current / external
  • setNameAsDisplayed → true / false
