AskVerse

Wallet-connected Q&A platform where good answers get gifted, not just liked.

AskVerse lets communities ask questions, share answers, and reward the most helpful responses with real XLM — turning knowledge-sharing into something tangible. Built for the APAC Stellar Hackathon under the Payment & Consumer Applications track.

Focus Area: Payment & Consumer Applications

AskVerse is a consumer-facing payment tool disguised as a Q&A app. The core loop — ask, answer, gift, rank — turns Stellar's fast, low-fee rails into an everyday reward mechanism anyone can use without needing to understand blockchain first. A user connects a wallet, browses questions like they would on any forum, and can tip a helpful answer in XLM in a couple of taps. That's the accessible, real-world payment experience this track calls for.

The Problem

Good answers online routinely go unrewarded. Upvotes and hearts feel good but carry no real value, so there's little incentive for people to share deep, useful knowledge — especially in communities (students, local business owners, hobbyists) where expertise is often given away for free. AskVerse closes that gap by letting anyone reward useful answers with a real XLM gift, instantly and without a payment processor in between.

How It Works

  1. Ask — post a question with a title and detailed body.
  2. Answer — community members respond.
  3. Heart — react to posts you find useful.
  4. Gift — send XLM directly to an answer that helped you.
  5. Rank — the leaderboard tracks total gifted score, surfacing the most valuable contributors.

Rewards aren't auto-minted — they're peer-funded. The leaderboard reflects real value transferred, not just popularity.

Cordy Minikit handles wallet connection and Stellar payment calls to Horizon; Supabase stores app state (posts, gift records, leaderboard scores) and keeps score reconciliation off-chain for speed, while the actual value transfer happens on-chain via XLM.
