In the source code of the MATIC token, one can see the below event:
event LogFeeTransfer(
address indexed token,
address indexed from,
address indexed to,
uint256 amount,
uint256 input1,
uint256 input2,
uint256 output1,
uint256 output2
);
After searching through the Polygon codebase I could not find a single place where this is emitted, nor much information about the event itself.
It seems to appear as the first event in the logs of a lot of transactions on Polygon.
Does anyone know what each uint256
actually represent? Or when this is emitted?
