COMPLIANCE & EXPLOIT TESTING
Simulate anomalies to trigger contract and circuit rejections
1. Credit Line Exploit Attempt
Attempt to settle an invoice of $120,000 when approved credit limit is $100,000.
2. Double-Factoring Fraud

Core Cryptographic Features
Mathematical Guarantees of Privacy & Security
Range-Proof Auditing
Proves invoice amount matches corporate credit line limits (amount ≤ credit_line) without ever exposing the numerical value of either on-chain.
Poseidon2 Nullifiers
Locks invoice uniqueness natively. The smart contract ensures a nullifier can only be settled once, mathematically ending double-factoring invoice fraud.
Protocol 26 MSM Speed
Utilizes native bn254 multi-scalar multiplication host functions. Lowers proof validation latency and reduces smart contract transaction costs by >75%.
