Our Ethereum Application Development Experience

App for Product Exchange

Xchange is a barter system dApp built on the Ethereum blockchain. The app is one of the significant and revolutionary ideas in the shared economy on the blockchain. It enables users to interact with various renters and exchange products with XCH, ERC-20 tokens.

App for Healthcare

We have developed a dApp for Healthcare industry on Ethereum Blockchain Platform. It allows users to exchange their health records with hospitals and other users anonymously. The app enables interoperability for health records and reduces the need for re-testing.
