CMTA Releases CMTAT Version 3.0.0
The Capital Markets and Technology Association (CMTA) is proud to announce the release of CMTAT v3.0.0, a major upgrade to its Solidity implementation of the CMTA Token (CMTAT) framework designed specifically for the tokenization of financial assets. This release significantly enhances the CMTAT version available for Ethereum and other EVM-based chains, by introducing several technical improvements that deliver a comprehensive tokenization smart contract, available as open-source code. In parallel, the CMTAT framework itself has also been refreshed to reflect its growing international relevance and incorporate recent advancements.
Addressing Industry Challenges
Smart contracts are an essential part of the tokenization process and are a critical piece of the developing blockchain-based financial market infrastructure. The CMTAT is a smart contract framework that defines the essential and optional functions needed to tokenize financial instruments, to ensure that a token effectively mirrors the behaviour of the security it is tokenizing. Initially designed for equities, debt securities, and structured products, the CMTAT framework outlines the core functions required to issue, trade and manage these securities – capabilities that are broadly consistent across global financial markets.
Recognizing that regulatory requirements vary by jurisdiction, the CMTAT reference implementation is built with a modular architecture. This allows users to adapt the codebase easily to meet specific legal or market needs.
Enhanced Interoperability and International Compatibility
This release aligns the CMTAT Solidity reference implementation with other widely adopted token standards, including ERC-3643 and ERC-7551, improving interoperability with the Ethereum ecosystem and international compatibility. CMTAT Version 3.0.0 now supports cross-chain functionalities with ERC-7802.
Purpose-Built Deployment Versions for Financial Use Cases
The CMTAT 3.0.0 upgrade includes multiple pre-configured deployment versions tailored to distinct use cases across capital markets:
- Debt Securities: A dedicated version enables the issuance of tokenized debt instruments, aligning with CMTA’s recent standard for the tokenization of debt using DLT.
- Opt-In Whitelist: Issuers can now implement whitelisting mechanisms without a separate rule engine or custom rule.
- ERC-1363 Tokens: A version supports ERC-1363 to facilitate Delivery versus Payment (DvP) settlement functionality.
- Stablecoins: A streamlined deployment focusing on address freezing, pausing, and optional whitelisting.
Governance and Industry Involvement
Development of the framework is overseen by the CMTA’s Technical Committee, chaired by Jean-Philippe Aumasson (Taurus), and includes experts from leading institutions such as BX Digital/Börse Stuttgart Digital, Fireblocks, Swissquote, Temenos, tokenforge, Mt Pelerin Group and UBS.
Implementation was carried out by Taurus, with an independent audit performed by Halborn.
Supporting the Digital Transformation of Capital Markets
The CMTAT v3.0.0 is open-source, available under a weak copyleft license on GitHub. Anyone can freely use, adapt, or integrate the code. With this release, CMTA reinforces its commitment to transparency, industry collaboration and cross-jurisdictional standardization.
As the financial sector accelerates its transition to blockchain-based infrastructure, token standards like CMTAT will be critical. Version 3.0.0 offers institutions a tested, flexible, and open-source foundation to issue equity, debt and structured products in tokenized form.
