Technical Implementation
The Technical Implementation describes the system’s underlying methodologies, standards, and frameworks that power the decentralized and modular platform for Real World Asset (RWA) tokenization. It focuses on how the components work together technically to ensure security, scalability, and compliance.
Core Principles
Adoption of Ethereum Standards: The system draws from well-established Ethereum standards:
ERC 725 (Universal Identity Profiles): For modular identity representation.
ERC 735 (Claims Holder): For claims management and lifecycle.
ERC 780 (Global Claim Registry): For decentralized claim storage and verification.
These standards ensure interoperability, modularity, and a foundation for decentralized identity and claims management.
Modular Architecture: Each smart contract is purpose-built with defined responsibilities. This separation of concerns ensures scalability, reusability, and independent upgrades of system components like identity, claims, and compliance.
Focus on Compliance: The platform incorporates jurisdictional attributes, dynamic risk scores, and credential management to support evolving regulatory requirements across different geographies.
Security and Upgradeability: OpenZeppelin’s proxy contracts are used for upgradeable architecture, enabling seamless feature enhancements and bug fixes while adhering to industry best practices for security.
System Layers
Identity Layer: Inspired by ERC 725, this layer provides the foundation for decentralized identity management. It ensures that each user has a unique, verifiable identity, including attributes such as jurisdiction, tax domicile, and risk score. A registry maintains a mapping of verified identities and enforces access control for operations like registration, restriction, or blacklist management.
Claims Layer: Using concepts from ERC 735 and ERC 780, this layer manages the lifecycle of claims, such as KYC, AML, and accreditation. Claims are cryptographically tied to their issuers and are verified in real-time based on attributes like expiration and proof hashes. This decentralized structure allows for seamless integration with external systems.
Compliance Layer: The compliance layer acts as the enforcer, validating user participation by aggregating data from the Identity and Claims layers. Compliance requirements are customizable and can be updated dynamically based on regulatory needs.
Security by Design
The system’s implementation includes multiple layers of security to protect user data, assets, and operational integrity:
Role-Based Access Control (RBAC): Ensures that sensitive functions, such as identity registration and claim issuance, are restricted to authorized roles like administrators and verifiers.
Emergency Pausable Functions: Critical functionalities can be paused in the event of unexpected issues or security threats.
Reentrancy Protection: Key operations are safeguarded against reentrancy attacks to prevent exploits and data inconsistencies.
Compliance-Centric Framework
Compliance is a cornerstone of the platform:
Jurisdiction-Specific Enforcement: User identities include attributes like jurisdiction codes to enforce region-based compliance requirements.
Dynamic Risk Management: Risk scores are calculated using predefined rules for jurisdictions and user categories, with periodic updates based on activity and compliance data.
Credential Validation: Claims such as KYC and AML certificates are verified in real-time to ensure regulatory adherence.
Third-Party Integration:
Our decentralized architecture seamlessly supports integration with external services, enhancing identity verification, risk assessments, and additional compliance checks. For instance, KYC verification is conducted through KYC Hub, which serves as our trusted external provider for this process.
Why This Approach?
The technical implementation leverages established Ethereum standards to build a future-ready system for RWA tokenization. This modular, secure, and compliance-focused approach ensures long-term scalability and interoperability across decentralized systems, while maintaining flexibility to adapt to new challenges and regulatory requirements.
