Govt. of Karnataka


The client was the centre for e-governance (CEG) of Government of Karnataka.

The client was looking for a blockchain based solution that will ensure government issued identification documents are not tampered with - from the time of attestation to presentment in various government departments.

  • We designed, built and delivered an innovative blockchain based solution (Multichain) to address above business problem.
  • The hash (digital signature) of documents were stored in the blockchain to help with validation of submitted documents with corresponding original signed versions
  • Integration with government databases like Aadhar e-sign, digi-locker and Aadhar verification

Muthoot Fincorp


The client is a leading player in financial services industry in India, with over 3000+ branch locations across the country.

One of the key pain points for the client was to guarantee immutability for certain types of documents transferred from branch locations to head office. Also, the solution was required to synchronize document transfers in real time, across the offices.

  • We built a Multichain based distributed ledger solution.
  • As and when a branch user entered manual data, it was picked up as a JSON extract and synced up with the blockchain.
  • The blockchain nodes were run in multiple branch locations across the company, thereby guaranteeing immutability.
  • The solution has been implemented in many client branch offices.

Zavy Secure


The client was looking at a ‘Rapid Prototype Development’ of an e-attestation POC. This POC was part of a larger requirement that the client is currently working with Malaysian government, towards a ‘Smart City’ initiative.

  • We engaged with the client, understood the needs, and built a blockchain prototype in a week’s time frame.
  • Solution was built on Multichain with Docusign integration.
  • Our multi-skilled team also quickly build an Android app to wrap the blockchain code and present a complete working prototype to the client.

Property management company(Stealth mode)


The client is an innovative USA based startup, engaged in building an asset-tokenization platform targeting US real-estate market. The client was looking at us to completely take over the blockchain part of their product solution.

  • Built the solution in Ethereum platform with Solidity as the language for smart contracts .
  • Exposed blockchain code as APIs.
  • Worked with US onsite clients and integrated Blockchain code in APIs, with their web- based product.
  • Improved cycle time and less hassle - blockchain development and troubleshooting competency was completely available offshore.
