The rise of the Digital Rupee marks a pivotal moment in India’s fintech industry, combining CBDC technology with the promise of secure and scalable digital money solutions. As fintech companies and fintech startups accelerate innovation, the need for robust software testing and security testing becomes critical.
Ensuring the safety of UPI transactions, protecting against cyber threats, and validating performance through penetration testing in cyber security are vital. From fintech software to CBDC platforms, testing ensures reliability and trust in digital money transfer services. This blog examines how testing enhances CBDC scalability, strengthens fintech technology, and fosters confidence in UPI India payments.
Types of CBDC
- Retail CBDC (e₹‑R)
Retail CBDC is designed for the general public—individuals, small businesses, and merchants. It enables secure digital transactions for daily usage, such as peer-to-peer payments, merchant purchases, and utility bill payments, acting as a digital equivalent of physical cash.
- Wholesale CBDC (e₹‑W)
Financial institutions use wholesale CBDC for large-scale, high-value settlements. It improves efficiency in interbank transfers, government securities transactions, and cross-border remittances, offering near real-time clearing with reduced operational costs.
Models for CBDC Issuance: Direct, Indirect (Intermediary), and Hybrid
India’s CBDC system explores three distribution models:
- Direct: In the direct model, the Reserve Bank of India (RBI) issues and distributes the Digital Rupee directly to end-users, without involving intermediaries. This gives RBI full control over issuance, distribution, and user account management.
- Indirect: Under this model, commercial banks and licensed intermediaries manage user accounts and distribute CBDC on behalf of RBI. While the RBI issues the currency, intermediaries handle customer interaction, wallets, and KYC compliance.
- Hybrid: The hybrid approach allows intermediaries to manage front-end services like wallets and customer support, while RBI retains control over the core ledger. It ensures operational scalability without compromising centralized oversight and security.
