Devery built the Devery Protocol, a set of smart contracts enabling products to be marked on the blockchain, allowing such products to have a ‘digital passport’ that allows anyone to build services catered to the owners of those products. These can be product verification services, but may also cover utility such as usage tracking, marketing or even ownership disputes.

DeveryJS is the JavaScript framework that allows applications to interact with these smart contracts without knowledge of Solidity or advanced knowledge of the workings of the blockchain.
