 This goes through all the instructions in the block, verifies that they indeed are `swap` instruction from the Whirlpool program and decodes the data of each inner instruction.
 Then it retrieves the transaction from the decoded inner instruction and source and destination accounts.
-The decoding is done with the `tokenProgram.transfer.decode` function from the Typescript ABI provided in the project.
