Paradex is a decentralised derivatives exchange that runs as its own high-performance Starknet appchain, incubated by the institutional crypto liquidity network Paradigm. It offers perpetual futures, options and spot markets with a unified cross-margin account, matching orders off-chain for speed while settling positions and collateral on-chain so traders keep custody of their funds. The design targets professional traders who want centralised-exchange latency and margin efficiency without handing assets to a custodial venue, and the platform rewards activity through an on-chain points and vault system.
