ZMAN PROTOCOL.
CLEAR RULES.

ONE IDENTITY.
TWO NETWORK ROLES.

Noir Wallet signs your profile session. Zcash Mainnet carries real ZEC payments. The collectible is issued on the configured testnet and indexed to your profile vault.

35–39 BITS.
FULL UINT64.

Each work unit receives a unique challenge bound to the signed profile. GPU and CPU workers search the complete 64-bit nonce range; the server recomputes every submitted hash before accepting it.

All ZEC amounts were fixed at launch and never follow later market movement. A progress counter measures attempts, not guaranteed completion.

PROOF FIRST.
PAYMENT SECOND.

A valid proof creates a mint pass. Noir Wallet sends the fixed ZEC amount to the configured shielded address with an order-specific memo. Delivery starts only after the required network confirmations.

• The displayed ZEC price is permanent for its supply tier.
• A transaction ID cannot be reused for another mint or market order.
• Real mainnet payment and testnet item delivery are intentionally separate rails.

PRIVATE TRADING.
COMING SOON.

The ZECMAN marketplace remains closed while ownership transfer, shielded settlement, and purchase safeguards complete their security review.

VERIFY EVERY
STATE CHANGE.

The browser is treated as untrusted. Ownership, listing status, price precision, transaction reuse, payment destination, memo binding, and confirmation count are checked on the server.

• Signed, HTTP-only session cookie with expiry and timing-safe verification.
• Same-origin mutation checks block cross-site listing and purchase requests.
• Atomic reservation and transfer prevent double sales under concurrent buyers.
• Seller ownership is rechecked at final transfer, not only at listing time.
• Mock wallet, payment, and issuer modes are rejected in production.
