The Capital Markets and Technology Association (CMTA) has expanded its integration of Chainlink, the industry-standard oracle platform, to power a programmable compliance solution for tokenized assets. Leveraging the CMTA Token (CMTAT) framework and Chainlink’s data and compliance standards, the solution simplifies policy enforcement by enabling asset issuers to embed and manage compliance policies within their tokenized assets with flexibility and efficiency.

As tokenization continues to expand across jurisdictions and asset classes, financial institutions face increasing complexity in managing compliance requirements and regulatory restrictions. This open-source solution unlocks a truly secure, programmable compliance layer to issuers of tokenized securities, combining the open token standard design of CMTAT with Chainlink's oracle infrastructure. Additional review of the integration of Chainlink to the CMTAT was provided by Taurus SA and the CMTA’s Technical Committee.

CMTA’s previous integration of Chainlink’s Cross-Chain Interoperability Protocol (CCIP) creates market opportunities to bring more tokenized securities onchain in an accelerated manner.

Chainlink ACE: Programmable, Automated Compliance for Digital Assets

Chainlink’s Automated Compliance Engine (ACE) is modular infrastructure that enables programmable compliance policies to be embedded within smart contracts and tokenized assets—historically a key constraint in the mass adoption of tokenized assets. Chainlink’s ACE provides greater flexibility and security to asset issuers while enabling them to retain full control over their token contracts, which has built-in support for cross-chain identity management, policy management, and monitoring and reporting.

CMTAT has now integrated Chainlink ACE, giving CMTAT users access to ACE’s Policy Manager—a customizable rule engine for defining, managing, and automatically enforcing compliance policies. Institutions can leverage ACE to manage who can access specific token functions, how compliance rules are enforced, and how those rules can be updated without altering the core token framework. In addition, Chainlink supports issuance controls for institutions through Chainlink Proof of Reserve and its Secure Mint capability. This unlocks new security guarantees for tokenized assets where additional tokens can only be minted if reserve collateralization is first verified. This automated safeguard prevents unbacked tokens from being minted, creating a built-in control layer that provides additional transparency, trust, and issuance integrity for tokenized assets.

Two deployment versions are available within CMTAT Solidity: standalone Policy Engine support or combined with access control. Both are available as open-source code under the Mozilla Public License Version 2.0.

"CMTAT was built on the principle that compliance should be modular and adaptable, not hard-wired into the token itself. Seeing ACE connect to CMTAT is a welcome step: it gives issuers the option to enforce compliance policies while keeping full control over their token contracts. We're glad to see the standard's flexibility put to work in this way, and we thank the teams at Chainlink and Taurus for their work on this integration." - Jacques Iffland, Chairman at CMTA

“We’re excited to see CMTA integrate Chainlink to power its compliance solution for tokenized assets. Via Chainlink’s data and compliance standards, CMTA is unlocking broader distribution, stronger market liquidity, and a clear path for institutional capital to move onchain.” — Frank Seibold, Global Head, Banking & Capital Markets Sales at Chainlink Labs.

Unlocking Tokenized Asset Adoption with CMTA

Capital Markets and Technology Association (CMTA) is an independent association formed by leading actors from the financial, technological, and legal sectors to create common standards around issuing, distributing, and tokenizing securities, enabling these assets to flow seamlessly into the digital asset economy. It was established by Lenz & Staehelin, Swissquote Bank Ltd, and Temenos AG, with the support of EPFL.

CMTA’s mission is to bring transparency, reliability, standards, and good practices to tokenized equity and debt so that financial intermediaries can handle them. Its certifications are designed to assure holders, trading-system operators, and business partners that tokenized shares or debt instruments were created in accordance with Swiss law and CMTA standards.

CMTAT: A Modular Approach to Compliance

The CMTAT framework is designed with compliance as a core feature, leveraging a modular architecture that separates token logic from compliance enforcement.

Within the CMTAT Solidity version, the center of this design is an external Rule Engine, which allows:

• Custom compliance rules per jurisdiction or asset

• Integration with third-party compliance providers

• Updates to regulatory logic without redeploying token contracts

This approach allows issuers to adapt to different regulatory requirements while keeping the underlying token contract the same across jurisdictions.
