What is BTCPay?

BTCPay Server is a free and open-source cryptocurrency payment processor which allows you to receive payments in Bitcoin and altcoins directly, with no fees, transaction cost or a middleman.

BTCPay is a non-custodial invoicing system which eliminates the involvement of a third-party. Payments with BTCPay go directly to your wallet, which increases the privacy and security. Your private keys are never uploaded to the server. There is no address re-use, since each invoice generates a new address deriving from your xpubkey.

Kolibri uses BTCPay as backend. You can either run your own BTCPay server to be fully independent or use a hosted merchant payment processor, such as BTCPay Jungle.

Does Kolibri support Lightning payments?

Yes! Kolibri supports Lightning if your BTCPay server has Lightning enabled.

Can you add Litecoin / Monero / my favorit cryptocurrency?

We don't plan to add any new cryptocurrencies to Kolibri.
