welcome back to nostr, security-conscious bitcoiner with a security key who just got locked out of X 🙌

bitchat (occupy wall st., 2011) https://blossom.primal.net/3e15a5c9448ab0f234acec0af673785bd8de84e4b74b50a5954e37b2e5d3fbe7.png

I kind of love how X just locked me out because of their security key rotation and even though I tried on 2 devices and it says "Success!", it won't let me log in anymore.

The payer doesn't have a mint interaction while paying, so as the payer, you're not talking to the mint for each transaction.
You can use VPNs or Tor if you want to hide your IP.
We're also integrating OHTTP into the Cashu protocol:

we like it when the mint doesn't know.
here: atomic swap of cashu token with a lightning payment provided by a third party lightning gateway. as long as htlc's are supported, the mint can't prevent it.
you can't do this with any other custodial system.

then my guess is something else must be going on. restore is very reliable.

2025-11-10 13:12:40

they have: fees.
this wasn't related to fees though, this was a classic bug.

2025-11-10 13:12:01

that must be some bug, if the seed is correct, restore should work without issues. pls try again in cashu.me

how? the mint is up, did you try to restore from seed?

2025-11-10 12:59:40

the guy who threatens to kill people publicly on the mailing list has changed his username, saying "btw it's the same guy" isn't doxxing, that's nonsense.

2025-11-10 12:56:18

- reply

if you refer to floppy, those are his public profile names. that's what his name was when he got banned of the Bitcoin mailing list for threatening to kill a core dev. everyone knows that.

2025-11-10 12:51:59

I have almost weekly calls with Bitcoin services and companies that want to integrate Cashu. Not for accepting payments, but to replace their user balance ledger with a more privacy-preserving alternative.

nice ux improvement for restoring ecash wallets from seed: cashu.me now stores your mint list on nostr. when you restore, all mints magically reappear.
old users need to enable it manually: settings > privacy > backup mint list on nostr
new users get this by default.

most people have no clue how fucking hard it is to build secure bitcoin applications. i’m not criticizing @npub1t5a…ahcl. i would never attack an open source bitcoin dev for actually doing the work.
indeed, i haven’t met a single productive person in my life with that attitude. not a single one. only the “outcasts” or “misunderstood geniuses” exhibit antisocial behavior like this. anyone productive knows that you need the support of others to build anything meaningful. its a self-organizing system. assholes get sorted out automatically.
these accidents can happen and they will continue to happen. they happened since the fist day of bitcoin’s existence. those who have never built anything with actual users have absolute no idea what they’re talking about. it’s an actually hard problem to build secure apps. it requires years of work and xp, tons of eyes on the core, and lots of users to test it.
i’m sorry this happened to you francis. you will recover and the next thing you build will be better than this. you can reach out to a whole community of other bitcoin devs for support if you need it, including me.
