What is the gas fee used in CDC? is it

USD?

CRO on Crypto.org and Cronos networks, ETH on ERC-20

I only have XRP oc CDC, I cant transfer to other coin due to insufficient balance, how can I solve this?

Maybe u have below the limit

even with 0 CRO, if I have enough XRP balance, then I can still do some transactions on CDC?

I didn't got what you really mean?

what do cdc means with insufficient balance? is it about CRO holdings as a gas fee?

In cdc app or exchange?

in cdc app

Ok

You want to change ur xrp to other crypto right?

Is it possible to swap with cro?
