Singapore digital green group Alpha Ladder Group ( ALG )’s artificial intelligence ( AI ) environmental, social and governance subsidiary, MVGX Tech, has been granted patent protection in Singapore for its CNT Carbon Stablecoin framework, a blockchain-native system that converts verified decarbonization activities into programmable carbon-backed stablecoins.

This system, ALG notes, forms the backbone of its global digital green infrastructure. It authenticates real-time decarbonization data, converts it into carbon credit assets and tokenizes them into carbon stablecoins with audit-grade precision.

In doing so, it elevates carbon from a niche asset class into a programmable financial instrument for cross-border payments and foreign exchange trading, laying the foundation, the company argues, “for a sustainable and inclusive financial system that rewards verified net-zero efforts”.

The framework, powered by internet-of-things sensors and AI technologies, represents a next-generation system of decarbonization-anchored smart contracts, the company points out, that “dynamically, uniquely and transparently reflects the decarbonization process of real-world assets – ranging from energy efficiency for buildings, renewable energy infrastructure for power grid, reforestation projects and direct air capture for carbon sequestration”.

As well, the framework also addresses regulatory and market complexities arising from Nationally Determined Contributions and Article 6 of the Paris agreement. The patent leverages a structure similar to American Depository Receipts, enabling the separation of national identity from environmental and financial characteristics of a verified carbon credit, a capability empowered and enhanced by robust distributed ledger technologies.

The first proof-of-concept for the stablecoin was launched in September 2021 and issued as a collective investment scheme unit token under Singapore’s Securities and Futures Act.

This early carbon stablecoin was backed by Chinese Certified Emission Reduction carbon credits, generated from a wind power project in Zhangjiakou City, co-host of the 2022 Winter Olympics. The project was verified and registered with China’s national carbon credits registry.

At a time when global carbon emissions have reached 41.6 billion tonnes ( 2024 ), the ability to scale a unified, trusted and programmable infrastructure for carbon-linked digital finance is no longer optional, the company says, it is essential.

“This announcement comes at a time of accelerating demand for stablecoin-powered cross-border payments and foreign exchange, alongside rising expectations for trusted carbon infrastructure,” ALG adds. “As regulators, capital markets and consumers call for a new generation of digital green infrastructure, this patented framework positions ALG at the forefront as a regulated, interoperable and impact-driven digital green infrastructure builder for a sustainable future”.
