We were joined by Hart Lambur, co-founder of UMA & Across, to discuss how building UMA’s next-gen optimistic oracle eventually led to unifying Ethereum’s ecosystem through Across’ intent-based bridge.
Universal Market Access (UMA) was founded by 2 ex Goldman Sachs traders that wanted to make global markets universally accessible through financial smart contracts that used synthetic assets on Ethereum. However, this was taking place long before the massive boom of DeFi summer of 2020. As a result, UMA shifted to building an optimistic oracle to power prediction markets as a decentralised ‘truth machine’, thus expanding oracle use cases. Through game theoretic models, UMA managed to properly incentivise its token holders to act as voters, rewarding them for good predictions & disputes, and vice versa. Later on, Hart Lambur also co-founded Across, an intent-based optimistic bridge that set out to create a seamless UX for unifying EVM chains. Through their solver network, Across managed to achieve fast (as low as 2 seconds) and cheap bridging, abstracting away crosschain complexities, without any security tradeoffs.
