A privacy-preserving NFT trading protocol built on the Aztec Network, featuring encrypted ownership, private cross-chain trading, and seamless integration with established L1/L2 collections.
Tezac revolutionizes NFT trading by leveraging Aztec's zkRollup architecture to encrypt ownership data and transaction details. This privacy-focused approach ensures complete confidentiality for trading, auctions, and gaming applications. By bridging established NFT collections from Layer 1 blockchains (e.g., Ethereum) to our protocol, Tezac uniquely combines the liquidity of major ecosystems with the privacy benefits of zero-knowledge proofs.
- Encrypted Ownership Records: All ownership data is fully encrypted on-chain
- Private Note Transactions: Trading occurs through encrypted private notes
- Identity Protection: User identities remain completely obscured during transactions
- Metadata Privacy: Optional encrypted metadata for complete NFT information privacy
2. Hidden Reserve Prices and Blind Auctions
- Confidential Reserve Pricing: Sellers can set reserve prices invisible to buyers
- Sealed-Bid Mechanisms: Participants submit encrypted bids visible only at settlement
- Private Auction Results: Only winning bids are revealed, preserving privacy for all participants
- Fair Settlement Guarantees: Zero-knowledge proofs ensure auction integrity
- Seamless L1 Integration: Bridge system connects with Ethereum, Polygon, and other major NFT ecosystems
- Wrapped NFT Mechanism: Original NFTs are securely wrapped for privacy-preserving transactions
- Cross-Chain Settlement: Complete trades across different blockchains without sacrificing privacy
- Flexible Unwrapping: Return NFTs to original chains when desired
- Verifiable Randomness: Cryptographically secure randomness for fair outcomes
- Private Participation: Join raffles and lotteries without revealing identity
- Transparent Results: Outcomes verifiable through zero-knowledge proofs
- Mystery Box Mechanics: Implement truly surprising reveals with privacy guarantees
- Time-locked Submissions: Prevent miners from exploiting pending transactions
- Encrypted Orders: Transaction details remain hidden until settlement
- MEV Protection: Built-in mechanics to prevent maximal extractable value exploitation
- Fair Market Access: Equal opportunity for all participants regardless of network advantages
Tezac builds on Aztec Network's privacy infrastructure with several key components:
- Smart Contract Layer: Privacy-preserving Noir contracts handling ownership and transactions
- Bridge System: Cross-chain communication protocol for L1/L2 NFT integration
- Frontend Application: User-friendly interface with complete wallet integration
- Privacy Middleware: Handles encryption, proof generation, and verification
Our modern React frontend offers a complete NFT management experience with seven core functionalities:
-

The interface features a sophisticated dark-themed design optimized for both aesthetics and usability:
- Color Palette: Dark background (#1A1A1A) with green accent (#a0e82c) for a distinctive look
- Typography: Modern sans-serif fonts for optimal readability
- Layout: Responsive design with sidebar navigation for desktop and optimized mobile views
- Interactive Elements: Subtle animations and transitions enhance user experience
- Accessibility: High contrast elements ensure readability and usability for all users
