Decentralized exchange D8X is developing a leveraged trading tool, scheduled to launch on the mainnet in August, that will allow users to trade Polymarket contracts with leverage. Co-founder Caspar Sauter said in an interview that leverage is the missing piece of the predictive market economy, which can improve market efficiency and increase potential returns. Launched on Polygon's zkEVM in January 2023, D8X closed a $1.50 million seed round and expanded to OKX's X Layer and Arbitrum in May and June, respectively. Sauter explained that D8X's system captures Polymarket's spot price via an oracle, similar to a traditional perpetual contract approach.
