About the company
Who We Are: Ethena Labs is building the first ETH based yield-bearing synthetic dollar. Arthur Hayes is a founding advisor and the team has deep experience across traditional finance and crypto engineering from firms such as Cerberus, Wintermute, Flow Traders, Deribit, Paradigm, Aave, Blockdaemon and Kaiko. We are backed by every major exchange and trading entities in the space. What we are Doing: We are building derivative infrastructure to enable Ethereum to transform into the Internet Bond via delta-neutral derivatives positions, to create the first crypto-native, yield bearing synthetic dollar: sUSDe. We believe creating a synthetic dollar which is not reliant on existing banking infrastructure is the single most important problem to solve and largest opportunity in crypto today. USDe will form the first part of a broader ecosystem of products we are building including fixed and floating rate internet bonds and composable repo leveraged markets.
