Can anyone explain what happend with these two transactions? I
wanted to deposit from my L1 to L2 in the loopring wallet app. A message appeared that the amount is less then the transaction or so and I clicked on cancel (continue was the other available option. These two transactions and some lost balance (~20$) are the result.
That is an approval fee for token to be used with contract. It is the same for all wallets. Each token has to be approved for use and then you can use the token itself.
