Check user balances

Via Polkadot.js UI

Click on "Developer" and then "RPC calls"
Select assets → freeBalance(accountid,assetid) fill in AssetID and press "Submit RPC call"
AssetID of the desired token can be found on Polkaswap in the "Account" section
This is the expected output. In this case, the VAL amount has been checked (look at AssetID)
Unfortunately, Polkadot.js supports only one asset for the network, that's why it shows XOR, but actually, it's asset that you asked - PSWAP, VAL, ETH, or DAI..
Letter before XOR shows the following:
k = x 1000
M = x 1000000
B = x 1000000000
m = / 1000
So, the shown amount is 80.434mXOR = 0.080434 VAL
