Building Zappr with the people who use it. Try it, tell us what confuses you.

What specific thing keeps you on custodial Lightning apps? Real answers shape what we build next. #nostr #bitcoin #lightning

Zappr is heading to the Play Store.

But a few people get to use Zappr before that.

We’re opening our tester community to people who want to get their hands on Zappr early, put it through its paces, and help shape what ships.

Boltz went offline in August and took Breez swaps with it, globally.

We migrated our swap layer to Spark. Lightning is back.

Still non-custodial. Same trust model. No user funds were ever at risk.

This is what building in public looks like: the blockers, and the fixes.

Month 3 on Nostr starts today. August: analytics live, mobile APK in tester hands, first grant application submitted. September: first real users, Blockstream Swaps research, Play Store submission.Building continues. https://usezappr.xyz ⚡ #nostr #bitcoin #lightning #buildingpublic

August didn't end with a launch. It ended with proof.

• Analytics live • Mobile build started • First grant application submitted • First real users came through the door

Still building. Still open source. Still Lagos. ⚡

Come see what we're building: https://usezappr.xyz

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.

Anyone navigated this? What worked, what didn't?

🛠️ Build note

Opened the mobile EPIC on GitHub (#11). Breaking it into sub-issues so the work is trackable:

#5 — Scaffold Expo/React Native #6 — Seedless key derivation SPIKE #7 — Breez SDK + NWC #8 — Nostr feed via NDK #9 — AI agent screen

If you've worked on Lightning + React Native with alternative swap providers, genuinely interested in what you ran into. #nostr #bitcoin #lightning #opensource

What zappr looks like on mobile 👇

Three tabs: Wallet. Feed. Agent.

Dark theme, orange accent. Built to run on the phone you already own not the one you wish you had.

#nostr #bitcoin #lightning #buildingpublic

Mobile stack decision for Zappr:

We're going with Capacitor over React Native from scratch.

Why? We can reuse our existing Next.js codebase instead of rebuilding from scratch. Faster to ship, one codebase.

The challenge: WebAuthn PRF is browser-native. On Android/iOS, we're researching a hardware-backed approach for secure key storage.

Issue #6 is our research spike for this.

Agent is back. 🎉

"abeg check my balance" → Pidgin response, real wallet balance.

Mobile is coming too. Android build is done, we're testing before Play Store submission. Early testers can try it through our community.

Big week. ⚡

🔐 Language accessibility isn't just about translation. Every new language shouldn't require rebuilding the product from scratch. We designed Zappr so we can keep improving language support while keeping the Bitcoin experience consistent. That's especially important when your goal is making self-custodial Bitcoin accessible to more people across Africa. #nostr #bitcoin #lightning #buildingpublic

Last month was four weeks of shipping, sharing, and listening.

The biggest lesson? Our roadmap changed more from conversations on Nostr than from our own planning sessions.

Building in public means the community isn't just watching the product evolve, they're helping shape it.

This month: • Mobile development begins • Grant application goes out • More people testing Zappr in the real world

Thanks to everyone following, testing, and sharing feedback. Every conversation is helping us build better.

#nostr #bitcoin #lightning #buildingpublic #opensource

One month of building with Nostr⚡⚡

Thank you to everyone who tried Zappr, shared feedback, replied, and helped us improve.

We're not going anywhere. Lagos is just the starting point. The mission is global

Deciding what to build next on Zappr🤔

Pick one option below. The feature with the most votes goes to the top of our build list.

A) Voice mode (speak Pidgin/Yoruba, agent replies aloud) B) Merchant POS (QR receive + NGN cashout report) C) Something else? tell us in the replies

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?

We're doing it live in Pidgin, Yoruba, Hausa, Swahili. Curious what others have tried and where it broke.

#nostr #bitcoin #lightning #opensource

Bitcoin terms, Pidgin version for anyone teaching newcomers:

Sats = na the smallest part of Bitcoin, just like kobo be for naira.

Zap = send small Bitcoin payment give person on Nostr.

npub = your public identity for Nostr. Na wetin you fit share freely make people find or follow you.

Self-custody = na you dey control your Bitcoin. Nobody hold am for you.

Passkey = your fingerprint, face ID, or device PIN fit unlock your account. No seed phrase. No yawa.

#nostr #bitcoin #lightning #buildingpublic

How the multilingual agent actually works:

The LLM layer handles translation and intent parsing before any wallet or feed action fires. Language is a prompt-level decision, not a separate codepath, so adding a new language is a prompt update, not a rewrite.

#nostr #bitcoin #lightning #buildingpublic

Genuine question for anyone who's built a Bitcoin cash-in/out flow for Africa: How did you handle the compliance side? We went the licensed-partner route — MavaPay handles the NGN rail so we don't have to become a money services business ourselves. Curious if others went a different direction and what that looked like in practice. #nostr #bitcoin #lightning
