overview
CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production by senior Solidity engineers.
Every contract undergoes a rigorous security audit using static analysis, formal verification, and manual review. We integrate
OpenZeppelinlibraries and follow established patterns to mitigate reentrancy, overflow, and access control risks.
- Production-Ready Code: Deploy
ERC-20,ERC-721,ERC-1155, or custom standards with 99.9% reliability. - Full Audit Trail: Comprehensive documentation, NatSpec comments, and a verified public Etherscan deployment.
- Post-Launch Support: Includes monitoring, incident response, and a clear upgrade path for future iterations.

Frequently Asked Questions
Get clear, technical answers about our compliant privacy infrastructure for institutional and regulated DeFi applications.
Our API provides a non-custodial, privacy-enhancing service that obfuscates transaction trails while maintaining full compliance. It uses zero-knowledge proofs (ZK-SNARKs) to generate privacy pools, separating funds based on provenance. Unlike traditional mixers, it generates cryptographic proofs of regulatory compliance (like source-of-funds attestations) that can be verified by VASPs or regulators without revealing the underlying transaction graph. This enables privacy for legitimate users while preventing illicit fund mixing.
