Compression uses the bubblegum program. Bubblegum uses anchor. You’ll need to decode the transaction using the bubblegum IDL, then pick the accounts matching the old leaf owner and new leaf owner.

If you view on explorer.Solana.com you can see these accounts.

  • Can u share some codes? I tried to deserialize data using Bubblegum instruction using burnStruct.deserialize(...) and transferStruct.deserialize(..) but all returns result for transfer instruction without any errors and I cannot detect that was transfer or burn instruction for example.

    Metaplex tends to generate idls with this thing called Solita. I don't like it. What I'd do is just use Anchor's Program.fetchIdl(program_id). Get the json. Find the instruction in the json. Find the index of the accounts you're looking for in that json, and then map it to the index of the accounts in the ix. Some similar logic here github.com/helium/helium-program-library/blob/ef2294b/packages/…

  • But how to detect that is burn instruction or transfer before?
