ZCash support plugin

This plugin extends BTCPay Server to enable users to receive payments via Zcash.

Warning

This plugin isn't maintained and nobody but the original author knows how it works. (@hhanh00)

We are looking for a maintainer. It seems that this plugin is more or less a copy-paste of the better-maintained Monero Plugin.

If ZCash is a fork of Monero, it is probably possible to support both in the same plugin easily.
