I am trying to understand a token swap transaction via Uniswap on Etherscan. Looking at the Uniswap V2: Router 2 contract for a transaction, I see the following;
My question is regarding the second Transfer of 0.002691070168940434 Ether from the Uniswap V2 Router 2 to the From address for the transaction. I see that this amount is added to the swap amount to get the amount in the Value field. What is this amount and what purpose does it serve?
