how is this different from npub.cash?
Hello World!
nuts.cash is an ecash experiment where your cashu tokens are constantly saved in the nostr.
If someone sent you ecash via DM, you will get it in this wallet.
Nostr and Ecash are a match made in heaven, ecash privacy and instant transfer brings a ton of powerful applications to the payment landscape.
You can configure the relay to connect to, the mint you want to accept and zap all of your friend using ecash.
Come and try it out at https://nuts.cash, you don't have to paste your private key, it works with all nip-07 extensions.

I need to check pub.cash, but it seems like they are focused on providing you with a lightning address where people can mint you ecash.
That you can then redeem when back online on your profile, so using ecash as a buffer to get lightning zap on nostr.
Cashu opens a ton of possibility, one I am excited about is nip-61, zap notes from your nostr profile with ecash. Checkout nutsack
this wallet is really an ecash wallet, you can mint and redeem your ecash, but we want to highlight how ecash can become an extension of lightning
