Last Notes npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr First testers gave us real feedback this week. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Thank you for reaching out and I'm truly sorry about what you're going through. We're a small team building with very limited resources ourselves and we're not in a position to send funds right now. I hope things improve for you and your community. Stay safe. 🙏 npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr If you've been curious about Zappr, this is your chance to try it. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Why does a Bitcoin grant organisation care about an app built in Lagos? npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Already in the app as a Settings option good timing. Will log the fee estimation edge case as a requirement inside #6 so it gets tested during the spike. 🙏 npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Why OpenSats specifically: npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr We submitted our first Bitcoin development grant application this month: OpenSats. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Phoenix SDK is actually what we're evaluating right now as an alternative since Boltz is down. The LSP dependency is the tradeoff we're weighing for a first mobile build it might be the pragmatic call. Thanks for the nudge. ⚡ npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr ldk-node through Uniffi is on our radar, especially for keeping the swap layer server-side. The tradeoff is more backend complexity but you're right that it gives us LSP flexibility long-term. Noting this for the mobile architecture discussion. 🙏 npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr The best products aren’t built in isolation. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr We're starting the mobile build. Lightning wallet on native is the hardest part, WASM doesn't translate from browser to native directly, and the swap layer adds more complexity. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr 🛠️ Build note npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr What zappr looks like on mobile 👇 npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Mobile stack decision for Zappr: npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Interesting point. We're using WebAuthn as an open web standard for passkeys, while keeping the project itself open source. The Vercel/custom-domain issue is mainly a technical deployment problem we're working through. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Agent is back. 🎉 npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr For anyone who's shipped a Next.js PWA with WebAuthn, how did you handle the RP ID when moving from a Vercel preview URL to a custom domain? npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr 🛠️ Honest update npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr 🔐 Language accessibility isn't just about translation. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Fair pushback. "Leverage is real" was about output, not safety. Those aren't the same thing. Vibe coding without review discipline is just fast mistakes at scale. The velocity only means something if it's paired with real hardening, not instead of it. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr 🔧 Umami shipped. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Try Zappr: https://usezappr.xyz npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Last month was four weeks of shipping, sharing, and listening. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Agreed. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr One month of building with Nostr⚡⚡ npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr It's been one month since we started posting here. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Those numbers are exactly why this matters. Non-English speakers are already here, the tools just haven't caught up yet. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Obrigado!!! Portuguese is absolutely on our radar, the infrastructure is the same, adding a language is a prompt update not a rebuild. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Deciding what to build next on Zappr🤔 npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Has anyone shipped a Nostr client with non-English support at the agent/AI layer, not just UI translation, but the AI actually responding natively? npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Love this addition. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr The agent runs on Claude, but the keys, wallet, and identity stay fully client-side, we never see them. No one controls the narrative if no one holds the keys. ⚡ npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr The alternative is English-only tooling that locks out 1.4 billion people. We'll take the tradeoff. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Exactly the thinking, compliance friction at the fiat layer shouldn't bleed into the Bitcoin layer. Keep them cleanly separated and users get sovereignty where it matters most. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Great question, and it's the split we designed around intentionally. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Bitcoin terms, Pidgin version for anyone teaching newcomers: npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr How the multilingual agent actually works: npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Language isn't a feature. It's access. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Well said.... npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Looks delicious 😊 npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Genuine question for anyone who's built a Bitcoin cash-in/out flow for Africa: npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Tech stack, for anyone curious: npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Our scariest bug: a logout flow that wiped a credential ID we thought was just metadata. Well it wasn't, it was the map back to the wallet. User locked out, keys intact but unreachable. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr How one fingerprint becomes two keys in zappr: npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Appreciate you sharing this 🙏 We're just getting started. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr The best investment is still remains the one that keeps you alive long enough to enjoy the rest. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Honest question for Nostr builders: npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Technically, yes.. 😂😂😂 npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Shipped this week: updated the README, opened our first public issues. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Why we chose NWC instead of building our own custodial backend. npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr I guess it's 2😂 npub1qs72af3vlexupszr53mfdaj0kxmg2d0ee97gus0vq88xrs984ntqfwr0te Zappr Been building quietly in Lagos for the past few weeks.
