We have successfully migrated all usernames and funds to the new stack, and all v1 services have now been retired.<br/><br/>If you’ve been using npubx.cash over the past few months, you shouldn’t notice any major changes. For users of the deprecated v1 stack, however, things will work a little differently.<br/><br/>The new architecture no longer mints ecash on your behalf. Instead, it holds the mint quote so your wallet can mint the ecash directly. This approach is safer, improves privacy, and gives you greater control over your funds.<br/><br/>This also means that npub.cash can now integrate only with full Cashu wallets, so the old claim interface is gone. The best way to use npub.cash is through a supported wallet, such as Sovran on iOS and Android or cashu.me on desktop and the web.<br/><br/>For anyone who doesn’t want to use one of these wallets, or who needs NIP-46 support, I’m working on a web-based npub.cash wallet. It will let you claim and spend your sats over Lightning. That’s next week’s project!<br/><br/>I’m incredibly grateful for the support and patience the npub.cash community has shown throughout this migration. With the old stack retired and the new architecture providing a much stronger foundation, I’m committed to improving npub.cash regularly and making the service better for everyone.<br/><br/>Thank you! ⚡🧡 </blockquote> 2026-08-14T16:22:44Z https://nostr.now/nevent1qqsplvrezz8yj8wxhyj2ek3jpmqs2vqr3crpnpwhfcfjx4lsvgsuwnqzyr8vpazdp4jddkwh58yycvc023n7w5kv3vr97uswsa9qhmgu2stdy6fnvfq In reply to <a href='/nevent1qqsd3vhfjhpepvsrf55ucm5w0pw96d53n3ss6uhuzn63way685htzrguaw5zg'>nevent1q…w5zg</a><br/>_________________________<br/><br/>Beautiful tribute, Gigi.

Nutzaps, P2PK locking of tokens to npubs show how Nostr can enable decentralized payments.<br/><br/>I can send you sats locked to your identity without you even having a lightning address in your Nostr profile. <br/><br/>We are barely scratching the surface of what Nostr&#39;s use cases. 2025-03-26T00:07:44Z
