I don't know who needs to know this, but here we go.
I had some issues with the Minibits wallet regarding an incorrect balance. Ok, let's delete it and recover the shit, I said. The recovery showed a zero balance. Then I asked myself what would happen if I used the seed phrase on the wallet.cashu.me, and, surprise, it worked. 🤷 (If it's too obvious, gfy 'cause I'm a normie!)
