Hi
I sent 40usdt to my friend on 29 Apr 2021 from MyEthereumWallet. I customized fee to 3.5usd (min fee was 6usd at that time). I thought with this fee transaction will be completed in 1 or 2 days, it was not time critical. But it is still pending till date, after 15 days.
Can someone help me how can I cancel this transaction?
