Copy to clipboard@cryptonly/medusa-plugin-cryptonly adds crypto payments to Medusa v2 via Cryptonly's hosted checkout.

Customers pay on a secure Cryptonly page and return to your store. You keep pricing in fiat. Payment status updates automatically via signed webhooks - no manual matching, no chargebacks.

Features

• Hosted checkout — no crypto UI to build, customers pay on Cryptonly's page
• Signed webhooks — payments capture automatically when paid
• Fiat pricing — price products in USD/EUR, crypto amounts calculated at checkout
• Sandbox mode — test the full flow before going live
• 0.5% per transaction — no setup fee, no monthly fee
