There is no problem with your exchange. It is normal for tokens to be displayed differently in different places. For example, ETH is displayed as weth in the polygon chain of MetaMask and eth in the ETH chain. We need to check the contract address of tokens. As long as the contract address is the same, it means the same currency
Of course I know what the W stands for. I just swapped Eth to Wrapper Luna. But in the MetaMask wallet, I see LUNC instead of WLUNC and the price is shown for LUNC instead of WLUNC.
That is, it is not the answer to evaluate you.
If I add to MetaMask Contract Ethereum for WLUNC: 0xd2877702675e6ceb975b4a1dff9fb7baf4c91ea9, it shows WLUNC but the price response is LUNC.
On the basis of what MetaMask actually feels the price, because it does not correspond to, for example, CoinMarketCap.
