Hart is the Co-Founder of Risk Labs, the foundation supporting the UMA and Across protocols. UMA is an optimistic oracle (OO) that can provide and verify arbitrary data on-chain. Across is a completely decentralized, low-cost and near-instant cross-chain bridge that is secured by UMA’s optimistic oracle.
Hart studied computer science before working as an interest rate trader at Goldman Sachs through the financial crisis. In 2013 he co-founded Openfolio, a personal finance tracking platform that was acquired in 2017 by an asset manager. He now leads a team of financial contract and oracle design researchers at Risk Labs.
