Ethena Labs has introduced a "Qualified Asset Framework" to expand collateral assets for USDe perpetual contracts, with BNB approved as the first new asset. The framework, released by the Ethena Risk Committee, sets strict criteria including a two-week average open interest over $1 billion and 24-hour trading volumes exceeding $100 million. XRP and HYPE also meet the framework's criteria and are candidates for future listing. The committee will regularly update and approve assets based on these standards and risk assessments.
