GRSPay Testnet

GRSPay Testnet: a free and open-source cryptocurrency payment processor which allows you to receive payments in Groestlcoin Testnet with no fees, transaction cost or a middleman.

GRSPay Testnet is a non-custodial invoicing system which eliminates the involvement of a third-party. Payments with GRSPay Testnet 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 tpubkey or vpubkey.

GRSPay Testnet is available at https://testnet.grspay.com/
