+# RFP-008 — Private NFT Marketplace
+
+## 🧭 Overview
+
+Build a marketplace for non-fungible tokens (NFTs) where ownership, bids,
+transaction history, and collector activity are confidential by default.
+The marketplace must operate within the Logos shielded ecosystem, enabling
+private minting, trading, and transfer of unique digital assets.
+
+NFTs serve as the cultural on-ramp for blockchain ecosystems, attracting
+users beyond the DeFi-native audience. A private NFT marketplace unlocks
+use cases that are impossible on transparent chains: anonymous credentials,
+private digital identity, confidential collectibles, and sovereign digital
+ownership where holding a high-value asset does not make you a target.
+
+The ideal team has experience in NFT marketplace design, shielded token
+standards for non-fungible assets, and front-end development for
+discovery-driven applications.
+
+## 🔥 Why This Matters
+
+NFT marketplaces drive massive user engagement and transaction volume.
+Magic Eden processed over $6B in volume and at times captured over 90% of
+Solana's NFT market. Base's "Onchain Summer" campaign used daily NFT mints
+to drive millions of transactions and onboard a wave of new users who were
+not primarily DeFi-focused.
+
+On transparent chains, NFT ownership is fully public. This means anyone can
+see exactly which wallets hold valuable assets, track collector behavior,
+and target high-value holders for social engineering or physical threats.
+Bids and offers are visible, enabling strategic manipulation. A private
+NFT marketplace on Logos solves these problems: ownership is shielded,
+bids are confidential, and transfers leave no public trace. This protects
+collectors, enables truly sovereign digital identities, and opens the door
+for privacy-sensitive use cases like anonymous credentials and private
+access tokens.
+
+## ✅ Scope of Work
+
+### Hard Requirements
+
+#### Functionality
+1. Support minting of NFTs directly into the Logos shielded pool — the
+   creator's identity and the token's initial ownership are private.
+2. Support listing NFTs for sale with shielded pricing (the listing
+   price is visible to potential buyers but the seller's identity is
+   not).
+3. Support private bidding on listed NFTs — bid amounts and bidder
+   identities are confidential until the seller accepts.
+4. Support direct private transfers of NFTs between shielded addresses.
+5. Support royalty enforcement on secondary sales, with royalty
+   payments flowing to the creator's shielded address.
+
+#### Security
+1. Implement provenance verification via ZK proofs — buyers can verify
+   that an NFT was minted by a specific creator (or collection) without
+   revealing the full ownership history.
+2. Include an emergency pause mechanism for marketplace operations.
+3. Implement escrow mechanisms for safe trade execution.
+
+#### Usability
+1. Provide a front-end UI for browsing collections, minting, listing,
+   bidding, and purchasing NFTs.
+2. Support collection-level pages with aggregate statistics (floor
+   price, volume) without revealing individual holder information.
+3. Provide creator tools for launching collections with configurable
+   minting parameters.
+
+### Soft Requirements
+
+1. Support for auction mechanisms (English auctions, Dutch auctions)
+   with private bidding.
+2. Support for NFT bundles and batch transfers.
+3. Integration with the Logos DEX (RFP-004) for NFT-fi use cases
+   (fractionalization, NFT-collateralized lending).
+4. Support for metadata storage via Logos Storage module for
+   decentralized, persistent NFT content.
+5. Exploration of private identity and credential NFTs — non-transferable
+   tokens that attest to properties without revealing them (e.g.,
+   "holder is over 18" without revealing age or identity).
