since #cashu #ecash tokens are bearer assets and there is no blockchain that knows which addresses **currently** hold which tokens, am I correct in presuming that if I delete a cashu.me PWA that has ecash in it, I'm also permanently deleting the ecash itself, and that "restoring the wallet from the seed phrase" in the future is not going to bring the tokens back?

If this is an accurate picture, there is going to be pain along the way in getting people to internalize that. People are used to "seed phrase" meaning "be as cavalier as you like with everything but this and your balance will be safe."

I'm speaking from experience: I just deleted a cashu.me PWA thinking I'd restore from my seed and when I did so and added back the mints and saw a zero balance it was only then that I realized where I was mistaken...

It was my understanding that the seed in combination with the mints would bring back the balance, but it seems that we are wrong then. I have never tried it myself and I am not sure about the mechanics behind it. Would like to understand it though. Might look into it later

as I thought about it more today: once I have an ecash token, I can email it to someone else, who can print it and hand it to someone else, etc. the mint can't be aware of any of that activity and can only check validity of a token on redemption. Hence the "true bearer asset" bit.

maybe there is some way for a wallet to ask the mint to give it back copies of tokens that it was known to have... havent looked into that.

**okay I'm a jackass**.

there is indeed a "restore ecash from seed" UX in cashu.me but you need to do it after adding mints. If you "restore" before you've added mints you'll have the false impression that "it worked but nothing resulted"

I did hear about that requirement. I wonder if this process can be improved. What if you don’t remember all the mints you were connected to?

there's an "export" too, which I think handles that for you (maybe)?

The Bullish ₿itcoiner 11mo ago

Are you talking about this? I haven’t really tested all this export and backup/restore stuff so I guess I’ll have to try it out someday.

Settings > Advanced > Export Wallet Data (very bottom)

I'm not sure what it does!

Oh nice. Will have to check it out. 👀
