I've been playing around with it a bit on the Fedi SigNet and it works very nicely.  I've tried sending sats to and from Mutiny Walet to nostr:npub1uq70uqgas9pyhds2zt57kr9se8rg3s68ztphjnq82ts8rzeknmeql7u0c2 alpha, and also I've got some sats from the Fedi faucet to the nostr:npub1mutnyacc9uc4t5mmxvpprwsauj5p2qxq95v4a9j0jxl8wnkfvuyque23vg.  I can't wait to use them on the mainnet!
