# Pure USD Overview Pure USD (PUSD) is a fully decentralized, delta-neutral stablecoin built on Ethereum. It was designed to address key challenges in decentralized stablecoins: low capital efficiency and limited supply scale. Here is our solution: 1\. Integration with decentralized inverse perpetual contracts enables the permissionless minting and burning of PUSD. 2\. Using ETH as collateral to open an equivalent short position ensures that the position will never be liquidated and always maintains a delta-neutral status, achieving maximum capital efficiency with full crypto asset collateralization. The market for longing mainstream cryptocurrencies through perpetual contracts and lending is worth tens of billions of dollars and continues to expand, providing immense potential for the supply of PUSD. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
