Groundhog is a suite of tools to power the crypto subscription economy. Groundhog consists of both a mobile wallet, and a payment gateway, Groundhog Pay, that can be installed on any web site via API or plugin. Customer and merchant funds are stored in state-of-the-art, non-custodial, multisignature smart wallets on Ethereum. Pre-authorized, recurring payments aren’t possible with today’s crypto wallets and payment gateways — Groundhog is building the technology to enable this huge category of payments for the new world of decentralized finance.
