Withdraw XRP From and exchange

[Yoche]

MY XRP is currently on MexC global I am trying to withdraw it, I am only given the choice of XRP network. I am not sure what withdrawal address to use. I have a ledger, I thought this was an ERC20 token. On Coin market Cap it shows that it is part of the BNB smart chain and a contract address associated with it. Please help I do not want to loose my tokens when i try to withdraw them.

XRP is the native token of the XRPL. Therefore you will need to withdraw your xrp into a xrp-account.

Ledger Nano has a dedicated support page for XRP. As stated above you will have to setup an account first.

The contracts part of the cmc page does not mean that the native XRP is a BEP20 token, this means that there is an IOU on the BNB Smart Chain that issues BEP20-XRP-Tokens. If you buy BEP20-XRP-Tokens you will need to withdraw them into a BEP20 address.
