💰 The Hidden Problem
≈$100,000 USD — Stellar distributed $100,000 at Meridian alone.
And has distributed over $30M USD in grants.
But behind this number exists a blind spot:
There is no native, private, and anti-sybil way to prove real participation in XLM-funded events.
Without this, blockchain doesn't touch the real world.
Today, reporting and metrics for community events and grants are:
- ❌ Manual
- ❌ Opaque
- ❌ Inconsistent
Result: Stellar is growing in the dark — no verifiable engagement data.
Meet.XLM is a native, private, and anti-sybil protocol based on ZK-UltraHonk and Soroban.
Transform event participation into verifiable on-chain reputation using:
- 🔐 Zero-Knowledge Proofs (ZK-proofs)
- ⚡ Soroban Smart Contracts
- 🎮 Dynamic NFT Badges
1. HOST logs into the app
↓
2. Creates an event
↓
3. Sets minimum XLM requirement (e.g., ≥100 XLM)
↓
4. Shares event link with community
↓
5. ATTENDEE selects event
↓
6. Generates ZK-proof (client-side) proving balance WITHOUT revealing wallet
↓
7. Proof verified on-chain via Soroban → Access granted
↓
8. At check-in → Receives NFT badge with rarity (Common/Rare/Epic)
↓
9. Social game: Scan others to reveal their NFTs
Result: Verifiable, private, fraud-proof event participation.

Mint NFT
1. ZK-Proof System (Privacy)
- Proves "has ≥X XLM" without exposing wallet or exact balance
- Generated client-side (no server trust needed)
- Uses Noir circuits compiled to WASM
2. Soroban Smart Contract
create_event(host, min_xlm, max_attendees, rarity_config)
mint_veiled_nft(attendee, event_id)
reveal_nft(nft_id, rarity_seed)
cross_reveal(revealer, target_nft)3. Dynamic NFT Badges
- Veiled before check-in
- Revealed with rarity at event
- Cross-Reveal: Social game to reveal others' NFTs
| Metric | Meet.XLM (Stellar) | POAP (Ethereum) |
|---|---|---|
| Cost per NFT | $0.00001 | $5-20 |
| Mint Time | 5-8s | 30-60s |
| Privacy | ZK-proofs | Address exposed |
| Payment | USDC native | External |
Example: Event with 200 participants
- Stellar: $0.002 total
- Ethereum: $2,000 total
