CinaMega Mega-Collections
Three template-based ERC-1155 mega-collections with billions of possible copies each, linked by a fixed bidirectional exchange.
| Type | Units | How to obtain |
|---|---|---|
| UCINA (1) | 1 | Free public mint (1,000,000/address cap) |
| MCINA (2) | 1,000 | Exchange only |
| CINA (3) | 1,000,000 | Exchange only |
Rate: 1 CINA = 1,000 MCINA = 1,000,000 UCINA
Exchange
exchange(fromType, toType, amount) — atomic burn + mint:
toAmount = amount × units[from] / units[to] (floor; dust burned on the source side).
Storage (four-layer fallback)
R2 → 4EVERLAND gateway → on-chain getBackupSvgRaw (5 QPS) → 503
Template SVGs and immutable IPFS CIDs are written to the contract and
permanently locked (svgLocked = true) — metadata trust base cannot change.
