"Minting" UXD is the process of creating new UXD in exchange for a USD-equivalent of a decentralized crypto asset such as SOL. For example, approximately 100 UXD can be created using $100 of crypto assets, making UXD highly capital efficient. The difference between the USD amount of crypto assets and the UXD created is due to (i) slippage (the change in price between a user's order submission and final execution) and (ii) trading fees on the underlying derivative exchange.
