I tried to withdraw m usdt via coinbase app using compund dapp. It said there is an error calculating miner fee. But as you see it took miner fee every time and sent to compound tether although i couldn’t withdraw. Compound took much more money then it gave to me. It is like a joke.
Compound does not receive transaction fees, they go to Ethereum miners. This issue of “error calculating miner fee” is an issue with your wallet, you can check in with Coinbase wallet for details.
