Key Terms
A quick reference for the core concepts used throughout this documentation.
| Term | Meaning |
|---|---|
| GFT | A phygital NFT linked one-to-one to a physical product, proving authenticity and recording ownership on-chain. |
| Phygital | Physical + digital — a real product paired with an on-chain twin. |
| TwinKer | A creator who plans a product project and creates its GFT design directly with AI, then brings it into the ecosystem. |
| AI design system | The system a TwinKer uses to generate GFT artwork directly, replacing the older external-designer approach. |
| TwinCode | A visual code — designed artwork rather than a plain QR — that can be scanned to reach a product's GFT. |
| TwinMeta app | The mobile app used to scan TwinCodes and tap NFC cards. Ownership authentication happens here. |
| NFC card | A card that comes with the product. Tapping it with the app is required to authenticate ownership, and it carries the card's CP. |
| Ownership authentication | Proving you own a specific item. Requires tapping the item's NFC card with the app and signing with your wallet. |
| Early Bird | A pre-participation phase where supporters earn priority purchase rights before a sale. Joining is a single tap; cheering afterwards is optional. |
| Elite Early Bird | The earliest Early Bird participants (roughly the top 3% by participation time), who get the first window to buy. |
| Early Bird cheer | An optional support message left after joining an Early Bird. Each cheer cracks the round's shared egg; when the final cheer lands, the egg hatches into a character and cheerers share a reward. |
| Level | An account's single progression tier. Leveling up requires both a point threshold and enough active invites; higher levels boost all future point earning. |
| Active invite | An invited friend who has taken part in an Early Bird or bought a product — signing up alone doesn't count. |
| CP | Creative Power — a fixed score carried by each NFC card. Tapping the card sends its CP to the product's TwinKer as support, and the sender earns TwinPoint. |
| TwinPoint | Activity-based reward points earned through participation (buying, Early Bird, authentication, cheering, referrals, missions). |
| Mission | A gamified wrapper around existing point-earning activities, shown on a project page. |
| Follow | A one-way relationship from a user to a TwinKer; follower count is a TwinKer's popularity signal. |
| TwinCoin | The token used within the TwinMeta ecosystem. See Tokenomics. |
