The ERC3643 Association today announces the completion of its OTC Derivative Collateralization Working Group, led by QualitaX, advancing the practical application of compliant tokenized assets within institutional OTC derivatives markets.
This second phase builds directly on the Association’s earlier work, “Bridging Compliant RWAs with Smart Derivatives”, which explored how ERC-3643 tokens and smart derivative contracts could improve efficiency and risk management across the derivative lifecycle.
This phase of the working group explicitly focuses on the use of ERC-3643 compliant stablecoins as eligible collateral for non-regulatory variation margin in bilateral OTC derivatives. The proof of concept does not address regulatory margin regimes, initial margin, or centrally cleared derivatives.
By concentrating on non-regulatory variation margin under the 1995 ISDA Credit Support Annex, the report examines a deployment path that is immediately relevant to a wide range of institutional counterparties, without requiring changes to existing regulatory margin frameworks.
Variation margin settlement remains slow and operationally heavy in many OTC derivatives markets. Payments are often limited by banking hours, cross-border transfers, and manual reconciliation, which can lead to delays, trapped liquidity, and higher operational risk.
The working group’s proof of concept shows that tokenized collateral can significantly shorten settlement times, reducing them from hours or days to less than ten minutes, including outside normal banking hours, while maintaining legal certainty and data confidentiality.
The proof of concept uses USD/BRL non-deliverable forwards (NDFs) as an example, as these instruments highlight common cross-border settlement challenges. However, the approach is not limited to FX derivatives. The same setup can be applied to any bilateral, cash-settled USD-denominated derivatives, such as interest rate swaps, credit derivatives, and equity swaps.
Key achievements include:
Using existing ISDA documentation, the PoC shows how margin calls and settlements can be completed in near real time, while all sensitive commercial information remains off-chain.
The solution uses neutral infrastructure, provided by Chainlink CRE, to monitor price stability, confirm settlement timing, and verify compliance. This reduces reliance on either counterparty’s internal systems and helps avoid disputes.
Legal analysis confirms that ERC-3643 compliant stablecoins can be used within existing ISDA agreements, including Credit Support Annexes, without changing their core legal structure. This supports a realistic path to adoption within today’s OTC derivatives markets.
Concluding the working group we would like to congratulate the members for coming together, including:
The ERC3643 Association is a non-profit organization advancing the adoption of the ERC-3643 standard for compliant tokenization. The association brings together industry leaders to foster collaboration, drive innovation, and create a more inclusive, efficient, and secure financial landscape through standardized, regulated digital asset infrastructure.
