BTCPay Server Checkout Addon for Krikkit

BTCPay Server Checkout Addon for Krikkit adds self-hosted crypto checkout to Krikkit. Point it at your BTCPay Server, send the buyer to that invoice, and unlock the pack when BTCPay reports InvoiceSettled. Krikkit is the Greenfield API client and the signed webhook handler.
