Generally all blockchains supported by COINQVEST should be displayed and available as payment method on hosted checkout pages. However, if the total payment amount is below the minimum payment threshold for a given blockchain then this blockchain is removed from the list. Stellar Lumens (XLM) are always available for payment.

Some blockchains have higher fees than others and small payments are not feasible in that case. The payment threshold for a given blockchain equals the minimum deposit amount for the associated anchor selected in the initial checkout API call. You can inspect the minimum deposit for each anchor here.
