overview
CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production by senior Solidity engineers.
- Production-Ready Code: Contracts are built for mainnet with comprehensive testing, gas optimization, and upgradeability via Transparent or UUPS proxies.
- Full Audit Support: We prepare contracts for third-party audits and provide remediation guidance to pass security reviews from firms like CertiK or Quantstamp.
- Deployment & Verification: We handle the full deployment lifecycle on EVM chains (Ethereum, Polygon, Arbitrum) with on-chain verification and initial configuration.
Deliver a secure, auditable foundation for your protocol in 2-4 weeks, reducing your technical risk and accelerating your go-to-market.

ARCHITECTURE
Core Engine Capabilities
Our EVM Jurisdictional Compliance Engine is built on a modular, audited architecture designed for enterprise-grade reliability and seamless integration. Each component is engineered to deliver specific, measurable outcomes for your compliance operations.
01
Real-Time Rule Engine
Dynamically enforce jurisdictional policies (e.g., OFAC, MiCA, FATF Travel Rule) at the transaction level with sub-second latency. Our deterministic rule sets eliminate false positives and ensure consistent on-chain compliance.

Frequently Asked Questions
Get clear answers on how our compliance engine integrates, scales, and secures your cross-border DeFi operations.
Our engine is deployed as a modular smart contract suite that acts as a middleware layer. It integrates via a standardized API and a set of upgradable rule modules. You connect your protocol's core functions (e.g., token transfers, liquidity provisioning) to our compliance oracle, which evaluates transactions in real-time against your configured rule sets. Typical integration takes 2-3 weeks and requires minimal changes to your existing Solidity code.
