“Before sending INTL, make sure you have the required amount of BNB in your account.” Please explain this message, I have this one.
Usually, that's the transaction fee. It means, you need to have some small amount of BNB before you can execute a transaction. You can already see how much they are requiring to carry out the transaction. This is because they are using the BSC network. As a BSC token, the fees are in BNB.
