I came across a post on stacker news that talked about Minibits wallet. I found this wallet interesting because of the combination of lightning invoice and eCash token. But I was discouraged by not being able to back up my wallet properly. I am asking SN platform about Minibits wallet, if anyone had tried out this wallet, should share his experience in the comment section. This wallet also allow flawless tipping of any Nostr profile.
cashu-ts
which is probably the best option to build a frontend Cashu wallet.
