CryptoCoffee

Open-source, fully static crypto tipping app.
No backend. No database. All profile data lives in the URL hash.

CryptoCoffee is an open-source alternative to Buy Me a Coffee for crypto donations.
Creators generate a shareable /tip#... link, and supporters pay using wallet extension, deep link, or QR code.

How It Works

1. Creator opens / and configures profile, wallets, and tip presets.
2. App serializes config as JSON and encodes it into Base64 URL hash.
3. Creator shares a link like /tip#eyJ....
4. Donor opens the link, selects amount/network/asset, and sends payment.
5. App builds payment URI and uses extension/deep link/QR flow.

All state is client-side and embedded in hash payload.
