I'm currently writing script to track wallet address by using connection.onLogs , and when i got the signature i called getParsedTransaction hoping to get the transaction details such as what wallet address initialize the transaction, what kind of transaction is it? swap, transfer or interact with a program? if swap what token was use to swap for what token? what's the amount? if it's transfer what token did the user transfer? what's the amount, what's the wallet address was used to send and receive and so on. when i console log the response from getParsedTransaction i keep getting different data field for each pair below, so i'm not sure how i can get these information if the data returned field changes everytime

// transaction signatures that i've been testing

Manually doing it would be a difficult task as each different DeFi interaction and different program interaction would result in different instruction data for each transaction. You should instead try using Helius' parsed transaction API endpoint: https://docs.helius.dev/solana-apis/enhanced-transactions-api/parse-transaction-s

It is not perfect, but parses some common actions like Jupiter swaps, NFT actions, and anything related to SPL tokens.

  • yeah, using that right now. thank you!
