The IMF published a paper that introduces, and illustrates the use of, the ASAP (Access, Service, Asset, Platform) conceptual Digital Asset Platforms (DAP) model. Just as the utilization of a seven-layer TCP/IP model has been fundamental to the interoperability of the internet, it is anticipated that the four-layer ASAP DAP model will similarly promote cross-platform and cross-border interoperability. The model is illustrated through examples and use cases, such as asset tokenization and the concept of purpose bound money (PBM) being explored by the Monetary Authority of Singapore (MAS).

The Monetary Authority of Singapore (MAS) published a paper proposing a common protocol to specify conditions for the use of digital money such as central bank digital currencies (CBDCs), tokenized bank deposits, and stablecoins on a distributed ledger. The whitepaper was supported by the release of open source software prototypes that demonstrate the concept of purpose bound money (PBM), which enables senders to specify conditions, such as validity period and types of shops, when making transfers in digital money across different systems.

The Bank of Ghana (BOG) has reportedly completed the second phase of Project Digital Economy Semi-Fungible Token (DESFT), a joint project with the Monetary Authority of Singapore (MAS) and the United Nations Development Programme (UNDP). The first phase saw the development of the blockchain-based Universal Trusted Credentials (UTC) system that enables micro, small and medium enterprises (MSMEs) to efficiently verify authenticity of key information, such as basic credentials, licenses, certificates, and trade records across borders. In the second phase, a cross-border payment was made using UTCs, the eCedi CBDC and a Singapore dollar stablecoin, using the Purpose-Bound Money (PBM) protocol.

The Reserve Bank of India (RBI) plans to add programmability and offline payments to its central bank digital currency (CBDC) pilot. "Programmability will facilitate transactions for specific/targeted purposes, while offline functionality will enable these transactions in areas with poor or limited internet connectivity." It sounds like programmability will take the form of "purpose-bound money" that embeds ("bounds") programming logic denoting its use based on programmed conditions that becomes "unbounded" once those conditions are met. https://www.rbi.org.in/Scripts/BS_PressReleaseDisplay.aspx?prid=57277
