How to interprete transaction correctly

#1

Hi,

I’m currently wondering if there’s any way to get a better understanding of the transactions shown in iotexscan? In detail I’m wondering what i did here:

There’s a transaction to the rewardingprotocol but it doesn’t seem to come back any for it?

Normall I’d expect something like

where I claimed VITA for IOTX but obviously that wasn’t the case for the other transaction?

Long story short: Is there any way to investigate further what the first transaction was used for?

PS: Background is that I’m currently preparing my taxes and so I have to stay sure every transaction is reported correctly…

Hello Bob​ ​,

Thanks for writing in.

You need to decode the data. You can try using something like this tool: https://iotexscout.io/opcode-tool

If you want even more information, you will need to know the contract ABI and decode the input. You can find a guide for Ethereum here https://medium.com/coinmonks/discovering-the-secrets-of-an-ethereum-transaction-64febb00935c - the process is very similar on IoTeX
