GRSPay is a free and open-source cryptocurrency payment processor which allows you to receive payments in Groestlcoin with no fees, transaction cost or a middleman.
GRSPay is a non-custodial invoicing system which eliminates the involvement of a third-party. Payments with GRSPay 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 or zpubkey.
