Smart Contracts Overview

Aztecas leverages cutting-edge privacy-preserving smart contract technology built on Aztec's Noir language, delivering unparalleled security and privacy for DeFi operations.

🛡️ Noir Language Security Advantages

Zero-Knowledge Privacy by Design

Aztecas smart contracts are written in Noir, Aztec's domain-specific language designed specifically for zero-knowledge proofs. This provides fundamental security and privacy advantages:

• Private State Management: All contract state is private by default, protecting user balances and transaction details

• Confidential Computations: Trading logic executes in zero-knowledge, hiding sensitive financial data

• Selective Disclosure: Users control what information is revealed and to whom

Cryptographic Security

// Example: Private balance verification without revealing amounts
fn verify_sufficient_balance(
    user_balance: Field,
    required_amount: Field,
    proof: Proof
) -> bool {
    // Zero-knowledge proof that user_balance >= required_amount
    // without revealing actual values
}

⚡ Technical Advantages

1. Enhanced Security Model

• Formal Verification: Noir enables mathematical proofs of contract correctness

• Compile-time Safety: Strong type system prevents common smart contract vulnerabilities

• Audit-Friendly: Clear, readable syntax reduces security review complexity

2. Scalability & Performance

• Reduced On-chain Data: Only proofs are stored on-chain, not full transaction details

• Batched Operations: Multiple trades can be proved and verified together

• Lower Gas Costs: Efficient proof verification reduces transaction fees

3. Regulatory Compliance

• Selective Auditing: Compliance teams can verify specific transactions without full exposure

• Privacy-Preserving KYC: Identity verification without compromising transaction privacy

• Jurisdictional Flexibility: Adaptable to varying privacy regulations
