ChainSafe Systems is a blockchain research and development firm on a mission to realize the potential of Web3 infrastructure through sustainable, open-source development. Our vision is to create a world with organizations that empower people to build and innovate through blockchain agnostic tools and other distributed technologies.
We are global leaders in the industry, unique in our work across multiple blockchain ecosystems, and currently are pioneering Ethereum, Ethereum Classic, Cosmos, Polkadot and Filecoin technology. We are actively pursuing the development of our own product suite, having recently released Files which allows users to upload and store files on IPFS and Filecoin with the goal of furthering development to provide a decentralized alternative to cloud storage.
ChainSafe is a unique company in a unique space, growing quickly and building a global reputation in this nascent space. Beyond offering experience across every major blockchain space to our team, we provide an open, inclusive, and supportive environment where we help folks reach their full potential as a human and as a professional.
