MAS Singapore Proposes Common Protocol for Cross-System Cryptocurrency Transfers

The Monetary Authority of Singapore (MAS) has published a whitepaper outlining a proposed common protocol for utilizing cryptocurrencies on a distributed ledger. The protocol aims to facilitate the seamless transfer of various digital assets, including tokenized bank deposits, stablecoins, and central bank digital currencies (CBDCs).


MAS’s initiative seeks to establish a standardized framework for cross-system transactions, ensuring greater interoperability and efficiency within the cryptocurrency ecosystem.

The recently released whitepaper by the Monetary Authority of Singapore (MAS) proposes a common protocol that empowers senders to define specific conditions while transferring digital money across diverse systems. These conditions encompass factors like validity periods and designated types of shops.

In a collaborative effort with international monetary organizations, financial institutions, and FinTech firms, MAS’s whitepaper comprehensively addresses technical specifications related to the protocol’s lifecycle, as well as its business and operating models. The aim is to establish a robust framework for seamless and secure cross-system transactions within the cryptocurrency realm.

The whitepaper introduced by the Monetary Authority of Singapore (MAS) is accompanied by the release of software prototypes showcasing the concept of Purpose Bound Money (PBM). PBM enables the transfer of digital money across diverse systems while adhering to specified conditions.

The protocol is designed to be compatible with various ledger technologies and forms of money, allowing users to access digital funds through their preferred wallet providers. To assess its practicality, financial institutions and FinTech firms are conducting trials to explore PBM’s application in different scenarios, including online commerce and programmable rewards.

The PBM whitepaper, an extension of MAS’ Project Orchid, seeks to stimulate further research among central banks, financial institutions (FIs), and FinTech companies regarding the design aspects of digital money utilization. In support of ongoing development and learning, the source codes and software prototypes of PBM, developed under Project Orchid, have been made publicly accessible.

These open-source resources provide practical examples of how PBM can be integrated into escrow arrangements, serving as a reference model to enhance interoperability across diverse platforms. The objective is to foster collaboration and understanding within the industry while advancing the adoption of digital currencies.

According to Mr. Sopnendu Mohanty, Chief FinTech Officer at MAS, the collaborative efforts have yielded significant progress in settlement efficiency, merchant acquisition, and user experience through the implementation of digital money.

The release of the whitepaper marks a crucial milestone in establishing digital money as a fundamental element of the future financial and payment landscape. The development reflects a strategic step forward in embracing the transformative potential of digital currencies.
