🛡️ ShieldPoint: Soroban Smart Contracts

This repository contains the on-chain logic for ShieldPoint, the privacy middleware for the Stellar Network. It leverages Protocol 25 (X-Ray) host functions to verify Zero-Knowledge Proofs (ZKP) natively.

🚀 Technical Highlights

• ZK-Verification: Uses env.crypto().bn254_multi_pairing_check() for efficient proof validation.
• Poseidon Hashing: Implements gas-optimized hashing for on-chain state commitments.
• Modular Proofs: Supports multiple circuit types (Proof of Balance, Proof of Residency, Proof of Age).

🛠 Installation & Testing

1. Install Stellar CLI.
2. Clone the repo: git clone https://github.com/aura-protocol/shieldpoint-contract
3. Build: stellar contract build
4. Test: cargo test

Milestones

• Implement BN254 Pairing Wrapper.
• Deploy Verifier Contract to Testnet.
• Integrate with SEP-10 Auth.
