Decentralized Finance (DeFi) and enterprise blockchain systems require rigorous smart contract auditing, but exposing proprietary source code for these audits violates competitive secrecy and multi-tenant privacy requirements.
zkAudit is an end-to-end Software-as-a-Service (SaaS) platform that solves this dilemma. It allows financial firms to cryptographically prove that their deployed smart contracts comply with safety standards using Zero-Knowledge Proofs (zk-SNARKs), without ever exposing the underlying abstract syntax tree or source code to third parties.
The production environment is live at: https://zkaudit.nepal.it.com/
(Note: As this platform handles proprietary cryptographic methodologies, the core compilation engine and microservice orchestration repositories are kept strictly private. The live link demonstrates the public-facing capabilities.)
- Interactive Dashboard: Secure client portal for submitting smart contracts without raw code exposure.
- Automated Scanning Pipeline: Real-time feedback on contract parsing and compliance evaluation.
- Cryptographic Proof Generation: Seamless backend generation of zk-SNARKs via Circom/snarkjs.
- Verification Explorer: Interface to view the status of proofs verified against the decentralized ledger.
The system is built on a highly scalable, multi-container microservices architecture designed to automate the proving and verification pipeline:
- Client Submission: Smart contracts are securely submitted via the SaaS interface.
- Containerized Analysis Engine: The backend parses the contract's Abstract Syntax Tree (AST) to evaluate operational codes against predefined security schemas.
- ZK Proving Engine: An arithmetic circuit generates a cryptographic proof validating the compliance of the AST.
- Decentralized Verification: The generated zero-knowledge proof is submitted to an Ethereum Layer 2 (L2) smart contract, acting as an immutable trust registry.
The following metrics were captured during system benchmarking, reflecting the platform's viability for high-throughput enterprise environments.
