You should be able to deposit to your Fountain wallet via BOLT11 - is this not working for you?
How do I get the ability to fund my wallet on fountain with the Nostr integration? I don't seem to have a way to send boosts. I need to support my favorite podcasts visibly through fountain!! #asknostr nostr:nprofile1qqswfa547pdmqkerzf2uen3agudc67wxffjmenqpge3dylc006fppyspzamhxue69uhhyetvv9ujuvrcvd5xzapwvdhk6tcaa833y
