I have recently reached out to Bitrefill to inquire about the possibility of adding support for Zcash. I have not heard back yet but after looking into their FAQ I saw the following statement:
“We do not have short-term plans to natively support additional cryptocurrencies. If we add new coins in the future, we will prioritize by the size of the user base.”
I wanted to make this post as a call to action for the community to voice their support with likes and comments so when I do get a response from them I can share this forum thread to highlight the community’s support for this idea.
You can also submit a request on their website here
