Job description

About the Company

We are building the Everything Store for Finance. We have combined three powerful financial primitives: Exchange, Asset Management, and Borrow/Lend, all seamlessly composable and accessible through one unified account that uses your entire portfolio as collateral, including spot and derivative assets.
