summary

Six hackathon finals present concrete demos and claims: a GitHub-scanning onboarding tool using retrieval augmented generation to match contributors to issues; a cross-border mobile‑money bridge that completes a 200 Kenya shillings demo via Tando LNURL; a recruiter-facing repo scoring system with on‑chain proofs via Stacks; a Chrome extension that tips devs via LNURL pay; a Nostr ride‑share that stops spam with proof of burn reputation; and an Arc/Bark gateway that shows 0 sats routing fees and 50–80% liquidity‑fee savings.
