A self-hostable Grin payment server for shops, creators, and sites: show a code, Grin lands in your wallet, with a verifiable Grin payment proof on receive. Workspace crates (gp-core / gp-nostr / gp-server / gp-wallet / gp-goblin-sender), a WooCommerce connector, a hosted /pay/<token> checkout, and NIP-44 v3 gift-wrapped payment DMs carried over the Nym mixnet. All secrets are read from the environment; none are committed.
