Aztec Integration

Aztec Protocol provides the privacy layer for ZKNetwork's on-chain operations, enabling confidential transactions and shielded computation.

Overview

Aztec integrates with ZKNetwork at multiple levels:

• Confidential ERC20 — Privacy-preserving token transfers
• Aztec Connect — Private bridging to Ethereum
• ZK Voting — Privacy-preserving governance on-chain

Confidential Tokens

ZKN-ZK (ZK-Native Token)

The ZK-native representation of ZKN on Aztec:

// Simplified interface
interface IZKToken {
    function mint(address to, uint256 amount) external;
    function burn(address from, uint256 amount) external;
    function transfer(address to, uint256 amount) external;
    function getPublicBalance(address account) external view returns (uint256);
    function getPrivateBalance(bytes32 accountKey) external view returns (uint256);
}

Privacy Features

Feature	Description
Amount Hiding	Transfers hide amounts from observers
Address Hiding	Sender/receiver not revealed
Selective Disclosure	Prove balance without revealing actual amount
Compliance Mode	Enable audit trails while maintaining privacy

Aztec Connect

Private bridging between Ethereum and ZKNetwork:

Ethereum L1 ←→ Aztec Privacy Pool ←→ ZKNetwork

Supported Operations

• ETH/ERC-20 bridging (private)
• Governance vote delegation
• Treasury operations
• Cross-layer state verification

Integration with Noir

Noir contracts generate proofs verified by Aztec's circuit:

Noir Circuit → ACIR → Aztec Prover → Privacy Proof → Verifier

This enables:

• ZK-PKI registration on Aztec
• ZK-Firewall proofs verified on-chain
• Private governance voting
