The presence layer for communities. Zero degrees of separation.
POAP made attendance collectible. Zero-In makes it count: status you can flex, people you actually meet, and a memory that compounds, while the community team finally sees one connected graph instead of fifty disconnected guest lists.
Every member gets a personal AI agent (an Agentic ID on 0G) embodied as a unique astronaut space panda. Showing up at events earns numbered Patches sewn onto its suit and Gravity toward the community's status ladder. The agent privately learns who you are and what you're looking for, then connects you with the right people in the room via double-opt-in intros. The community gets aggregate intelligence it has never had, never individual data.
"We don't ask members to trust Zero-In with their data. The token standard makes it impossible for Zero-In to have it."
Built solo + AI pair at ETHGlobal Lisbon 2026 for the 0G track, implementing the flow a 0G team member described to us at the booth on Friday.
| 0G feature | Where it runs in Zero-In |
|---|---|
| 0G Chain (Galileo, 16602) | ZeroInAgent (ERC-7857 Agentic ID) + ZeroInPatches (ERC-1155 per-event editions) |
| 0G Compute (Router) | Panda portrait generation, match reasoning, intro messages, debrief chat, Ask-the-Room synthesis. Receipts: docs/compute-proof.md |
| 0G Storage | Encrypted agent memory (AES-256-GCM per user); merkle root hash committed on-chain as IntelligentData |
| ERC-7857 (Agentic ID) | Agent token with encrypted intelligent data, authorizeUsage consent, append-only growth per patch/debrief |
| ERC-8004 | Every agent registered in the Identity Registry, discoverable on 8004scan |
| Contract | Address | Explorer |

- Next.js 16 + Tailwind on Vercel. Wallets are Privy embedded (email login, wallet invisible); users never sign transactions or pay gas.
- Relayer pattern: funded server-side keys hold MINTER_ROLE/OPERATOR_ROLE and submit every write, round-robin.
- Gasless on-chain consent:
authorizeUsageWithSig(EIP-712). The member signs typed data in their embedded wallet (free); the relayer submits it. The matcher can only run agents whose owners signed. Revocable the same way. - Panda art: portrait generated once on 0G Compute; country flag and patches are deterministic SVG overlays (flags are never AI-generated); tier evolution is frame/aura layers on a constant portrait.
- Trust model: attestation is a policy per patch type. See docs/trust-model.md.
- Contracts derive from 0G's own simplified
agenticID-examples("simplified for demonstration"); the production path is the full0g-agent-nftsuite with TEE/ZKP transfer verification. - MVP matching runs centrally on 0G Compute over agents that granted
authorizeUsage: semantically agent-to-agent, mechanically one matcher. True peer A2A negotiation via ERC-8004 discovery is roadmap. - Demo NFC tags are static-URL ("venue-attested-lite"); production uses NTAG 424 rotating auth.
