The Reserve Bank of India (RBI) has officially rolled out a retail sandbox for its Central Bank Digital Currency (CBDC) on October 8, 2025. This marks a major milestone in India’s journey towards a more digital financial landscape. With this initiative, fintech companies now have the opportunity to test and launch innovative products for the e-Rupee retail pilot, which first kicked off on December 1, 2022. This step not only bolsters India’s ambition to lead in digital currency adoption globally but also creates a regulated environment for experimenting with new digital payment solutions.
About the RBI Retail CBDC Sandbox
The sandbox is designed to allow fintech firms (or fintechs) to access APIs, build prototypes, test products, and experiment with innovations in a controlled environment using the digital rupee infrastructure.
The RBI retail sandbox allows selected fintechs to build tools that,
- Integrate with the e-Rupee infrastructure
- Simulate real-world retail transactions
- Innovate around payment, settlement, and tokenisation processes
This sandbox is an extension of the ongoing CBDC pilot, which now has around 7 million users across India, and is running in collaboration with several major banks.
What is the e-Rupee (CBDC)?
Digital Rupee (e₹) or the central bank digital currency (CBDC) is issued by the RBI. It offers features similar to physical cash like convenience of use, guarantee of the RBI, finality of settlement, among others. Digital rupee transactions are expected to be faster, cheaper, and more secure, and can be used without internet connectivity through offline wallet modes.
Key Features of the Sandbox
With the retail sandbox, fintech players can now access APIs, build prototypes, and test products in a secure, simulated environment.
• Fintech Collaboration: This feature allows startups and tech companies to develop applications using RBI’s CBDC backend.
• Tokenisation Support: Digital rupee tokens serve as secure, transferable representations of money.
• Real-Time Testing: It enables the testing of retail payment models, POS systems, digital wallets, and cross-platform integration.
• Wholesale Layer Involvement: The sandbox utilizes the wholesale CBDC as the foundation for retail testing.
This initiative is led by Suvendu Pati, Chief General Manager at RBI, who reiterated that token-based systems can revolutionize banking with more fluid, interoperable, and faster transactions.
