@nakedwinnie thank you very much, it worked! for the next time,I think the best way is to buy FTM in directly binance then, send this FTM to my wallet’s FTM mainnet public address,right? FTM transfer fee is not much. since,I tried to send BSC to my wallet at first,swapping it to HEC was really painful (bridge and swap) and costly. If I can learn using the wallet efficiently,I want to stake more tokens in there. there is also dfx for staking stable coins,too. so,I can split the eggs in different baskets.
