Onbloc is an IT company that directly creates and operates services used by actual users, based on blockchain technology.
We are building comprehensive Web3 services, from wallets to explorers, DEX, and nodes, aiming for 'services that anyone can use,' even if they are not familiar with blockchain. We prioritize user experience and service stability over the technology itself, and we focus on creating Web3 services that people can safely use every day. We are accelerating our business expansion after raising approximately 6.1 billion KRW in investment. We are looking for someone to join Onbloc's growth journey.
Currently, we are building an organization that directly designs and reconstructs blockchain cores at the protocol level, moving beyond simple service development.
We are in the stage of launching services and are conducting projects to create core architecture in alignment with Jae Kwon, co-founder of Cosmos, a well-known figure in the blockchain industry.
