Securing India'sDigital Economy.
A-SPARSH — India's first offline CBDC wallet and RBI HaRBInger Hackathon Winner. Secure digital rupee payments on any ₹5,000 smartphone without internet or hardware secure element.
Financial Inclusion at Scale.
400 million Indians use budget smartphones with unreliable connectivity. Existing solutions for digital payments require expensive hardware or constant internet leaving out the people who need digital finance the most.
A-SPARSH was built to close this gap. Our platform delivers hardware-grade security entirely in software making the RBI's digital rupee accessible on any ₹5,000 Android device, completely offline.
Partner with usAdvanced Cryptographic Architecture.
Every product we build rests on a foundation of rigorously designed cryptographic protocols developed in-house, patent-pending, and validated through India's most demanding financial innovation challenges.
Privacy-First Architecture
Transactions are validated through cryptographic proofs — verifying correctness without exposing amounts, identities, or any transaction metadata to third parties.
Multi-Layer Security
Seven independent security layers, each blocking a distinct category of attack. A single layer compromise does not compromise the system — defence in depth by design.
Offline-Resilient Design
Cryptographic guarantees that hold without server involvement. Payments are verifiable locally, with deferred reconciliation when network access is available.
Software-Defined Security
Our proprietary cryptographic approach replicates hardware secure element guarantees entirely in software — eliminating the need for specialised chips.
Tamper-Resistant State
Cryptographic mechanisms prevent rollback, replay, and state manipulation attacks — even when an adversary has physical access to the device and its storage.
Regulatory Alignment
Designed from the ground up to align with the Reserve Bank of India's CBDC framework and digital payment compliance requirements.
Our core cryptographic methods are patent-pending. Technical details are disclosed under NDA to qualified partners and institutions.
