Work done

Browser extension for Chrome, Firefox, and Opera Online wallet for Klaytn blockchain UI and functionality for DApp connection QA testing for multiple browsers


Kaikas is a browser extension acting as a web wallet and interface for regular users to have access to the Klaytn network. It was designed as an equivalent of Metamask extension with added functionality and user-friendly interface, allowing to seamlessly connect with Klaytn DApps, authorize and send transactions, and manage your cryptocurrency web wallet. The extension was developed for Chrome, Firefox, and Opera browsers.

Technologies used:



Ground X is the blockchain subsidiary of Korea’s largest mobile service provider, Kakao, with over 50 million active users. By developing a scalable platform providing a multitude of services through its DApps, Ground X aspires to substantiate the value and utility of blockchain technology.

Ground X has its own functional open-source blockchain, Klaytn. The platform provides an enterprise-friendly environment for developers to work on the creation of blockchain services and DApps. Having recently launched Klaytn Mainnet, the company was faced with a problem of not having an interface for average users to interact with Klaytn and explore its vast possibilities.
