I added eth to trust wallet. I’ve also added several altcoins (reef, forth, lto, and 3-4 others) and swapped a part of eth for each of them. However, every transaction failed and said error. Does anybody know why?
Provide screenshot here would be better, so we can help to identify the problem of your swap.
On trust wallet, there are some Ethereum DEX app such uniswap or 1inch. Have you tried it ? Im using trust wallet on BSC and using pancakeswap to swap/exchange my bnb to other tokens. You should be able to do that using uniswap or 1inch on Ethereum network too.
