Analyst's Notes:

• All trades/listings that happen on AB2 happen via an escrow wallet, and not the user's direct wallet.

• The user init's the escrow with some Algo (~0.2 ALGO) in most cases, and also transfers the assets to list to the escrow.

• A buyer interacts with the listing via the escrow.

• When a buy happens, there are 2 types of transaction groups that can happen. All depending on the scenario:

  • SCENARIO #1:
    • All listed item(s) in the listing/escrow have been bought.
    • The escrow transfers the collected amount to the seller, minus any royalty fee which is transfered to the creator. (10% of the amount) and closes itself.
    • Such transaction groups have a total of 5 transactions in them, covering all the events.
  • SCENARIO #2:
    • Only partial listings have been sold.
    • The escrow will retain the collected amount/royalty fee until all items have sold.
    • Such transaction groups have a total of 4 transactions in them.

• Transaction groups having <=4 txns in them are likely cases where the user lists/inits the escrow or cancels the listing entirely/partially.

• One will have to be careful taking in only actual trades happening and not the escrow listing/delisting!

• Further, another good check is to make sure the to check if the algo payment txn is at rank 3 in the transaction group

DOUBLE CLICK any single label/legend to focus on that particular category!
