# Perpetual Futures #### Abstract Perpetual futures markets are officially supported on VDEX with the introduction of VRC-10. Perpetual contracts trade independently from spot markets and are tethered to the oracle price via an hourly funding rate. The margin required to open a position is discounted on a pair's maximum leverage factor. VDEX will close a position on behalf of the user should their equity decrease below the requirement. #### Features * Crypto derivatives without expiration * Isolated and cross margin * Maker and taker orders * Funding rate * Liquidation * Leverage --- # 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.
