You could skip the Minibits step if you wanted to. You can go directly from Boardwalk to Mutiny.
Just scan a Mutiny invoice with Boardwalk.
Discussion
I guess that makes sense that I could just paste in the mutiny wallet ln invoice. First use I was just happy that the token could be either usd or sats cashu token. When I saw that intuitively I redeemed in Minibits.
Not sure if the camera opens to scan on this particular mobile device with CalyxOS using tor?
We do have the ability to scan from the Send button, but we've never tested it with CalxOS so I'm not sure how that works. You may need to grant permission somewhere (on iOS safari/chrome will prompt you).
