Algorand

Hi,

so basically I'm trying to build Algorand's Ledger parser and have some hard time while trying to figure out if a Transaction Group consisting of the Application Call and Payment/Asset Transaction is a reward or maybe a person pulling the asset out of the pool.

Or do I need to maintain a list of contracts in order to be able to find out what has happened?

EDIT:This is the current logic I'm trying to follow now:

 //Variant #1 (Stake/Unstake/Rewards:]):
//Transaction 1: ApplicationCall && InnerTransactions == null
//Transaction 2: Payment or AssetTransfer 
//Variant #2 (Swap):
//Transaction 1: ApplicationCall && InnerTransactions != null
//Transaction 2: Payment or AssetTransfer 
//Variant #3 (Liquidity Providing => OUT)
//Transaction 1: ApplicationCall && InnerTransactions != null
//Transaction 2: 1 AssetTransfer or Payment from our wallet (LP Token)
//Transaction 3: 1>AssetTransfer or Payment to our wallet (currencies from pool)
//Variant #4 (Liquidity Providing => IN)
//Transaction 1: ApplicationCall && InnerTransactions != null
