ARCHITECTURE
Core Components of Our Travel Rule System
Our modular, on-chain compliance solution is built for enterprise-grade security, seamless integration, and regulatory certainty. Each component is designed to reduce your technical and operational burden.
01
Smart Contract Rule Engine
A decentralized, immutable rulebook deployed on-chain. Define and enforce compliance logic (e.g., jurisdiction checks, threshold monitoring) with deterministic execution, eliminating manual review bottlenecks.

Execution Verifiability
02
Secure VASP Directory
A continuously updated, on-chain registry of verified Virtual Asset Service Providers (VASPs). Automatically validates counterparty credentials and required Travel Rule fields (beneficiary name, address) for every transaction.

5,000+
VASP Entries
03
Encrypted Data Pipeline
End-to-end encrypted channel for secure, PII-compliant data exchange between originator and beneficiary VASPs. Built with zero-knowledge proofs where applicable to minimize on-chain data exposure.
AES-256 / ZK
Encryption

Architectural Decision Analysis
Build vs. Buy: Smart Contract System vs. Traditional SaaS
A technical and financial comparison of developing a proprietary Travel Rule solution versus implementing Chainscore's audited smart contract system.
| Decision Factor | Build In-House | Chainscore Smart Contract System |
|---|---|---|
Time to Initial Deployment | 6-12 months | 4-8 weeks |
Upfront Development Cost | $250K - $600K+ | $50K - $150K |
Security & Audit Overhead | High (Unaudited Risk) | Low (Pre-Audited, Battle-Tested) |
Regulatory Compliance Coverage | Your Responsibility | Built-in (FATF, Travel Rule) |
Ongoing Maintenance & Updates | Dedicated Internal Team | Managed Service (Optional SLA) |
Cross-Chain & Protocol Support | Custom Integration Required | Native (EVM, Solana, Cosmos SDK) |
Time to First Transaction | Post-Deployment (Months) | Immediate (Live Network) |
Total Cost of Ownership (Year 1) | $400K - $800K+ | $75K - $200K |
Implementation Risk | High (Unproven, Complex) | Low (Proven, Deployed) |
