XMT? what do you mean the nativ token of this dex swap
https://coinmarketcap.com/id/currencies/metalswap/ ?
I checked the new listing on dex and this is what I found,
Sorry, maybe you previously got this from a presale or event prize in the past? Never mind
.
You can try
Pencake swap with pair XMT to WBNB, or
UNIswap on chain polygon with pair USDCe to XMT or chain optimism with WETH and USDCe. If it is already a pair (bnb, usdc, eth) P2p transactions are easier or you can send to other exchanges including local exchanges in your area if they are available. because it is very accepted anywhere as long as it is in a country that allows it because the 3 coins are very easy to use and many need it, hopefully your journey is enjoyable in getting used to transactions and exchanging crypto including on dex.
note: leave the gas fee with the chain that will be used. maybe 1-5 $ that will not be used all, cex den dex is different.
