ERC-3643 Tokens for Compliant Derivative Collateralization
Overview
This project explores the integration of the ERC-3643 compliant security token standard with Smart Derivative Contracts (SDCs). By embedding regulatory requirements directly into the token framework, the initiative demonstrates a viable path for institutional stakeholders to utilize tokenized assets—such as money market funds—as margin for uncleared OTC bilateral derivatives.
Project: Multi-stakeholder collaboration (including Tokeny, Chainlink, CMS, and Zama)
Focus: Tokenized Real-World Assets (RWAs) as derivative collateral

The Challenge
The uncleared Over-The-Counter (OTC) derivatives market, valued at approximately $700 trillion, is plagued by deep-seated systemic inefficiencies:
Manual Overhead: Roughly 38% of operational resources are consumed by manual tasks such as trade capture and portfolio reconciliation.
High Dispute Rates: Disagreements over collateral valuation and reconciliation lead to a 45% dispute rate on margin calls.
Capital Friction: Traditional cash collateral often earns minimal interest compared to yield-bearing tokenized alternatives.
Operational Risk: Reliance on counterparty non-automation increases errors, delays, and counterparty credit risk.
The Approach: ERC-3643 + Smart Derivatives
The proposed framework leverages a suite of open-source smart contracts to automate the derivative lifecycle while ensuring strict regulatory adherence.
Integrated Compliance: ERC-3643 embeds KYC/AML rules and jurisdiction-specific restrictions directly into the token architecture.
On-Chain Identity: All participants must possess a verified OnchainID. The system performs real-time verification of accredited investor status and jurisdiction before allowing any trade activity.
Deterministic Execution: Smart contracts (inspired by the ERC-6123 standard) automate daily mark-to-market calculations, margin calls, and final settlements based on pre-agreed valuation models.
Automated Collateral Management: ERC-3643 tokens are locked into the derivative contract as initial margin. Transfers are automatically validated against compliance rules throughout the contract's life.
Practical Proofs-of-Concept (PoCs)
The project successfully demonstrated two primary institutional use cases:
USDC Yield Index Cash-Settled Forward:
Purpose: Allows participants to hedge against or speculate on volatile DeFi lending rates.
Infrastructure: Utilizes Chainlink oracles for real-time yield index data to drive automated cash settlements.
EURUSD Forward with Delivery:
Purpose: A physical FX forward enabling firms to lock in exchange rates for future currency delivery (e.g., repatriating dividend payments).
Infrastructure: Relies on Frictionless Markets institutional deposit tokens (fsUSD/fsEUR) as the primary settlement assets.
Key Benefits & Results
Operational Savings: Automation could potentially deliver double-digit basis points in annual cost savings by eliminating manual reconciliation and reducing dispute rates.
Capital Optimization: Tokenized collateral (e.g., BlackRock’s BUIDL) continues to generate yield while posted as margin, unlike traditional cash.
Risk Mitigation: Continuous revaluation and "settle-to-market" (STM) mechanisms prevent the accumulation of large, uncollateralized obligations.
Legal & Regulatory Outlook
The framework is designed to align with existing ISDA documentation. While the smart contract automates execution, the legal relationship remains governed by an underlying ISDA Master Agreement, with bespoke amendments required to accommodate digital assets as collateral. Future development will focus on integrating Fully Homomorphic Encryption (FHE) to maintain trade confidentiality while fulfilling compliance requirements.
