Avantis is a decentralized on-chain exchange designed for cross-asset leveraged trading. It lets users go long or short on synthetic crypto, forex, and commodities, while liquidity providers supply USDC to power the markets. Because it combines synthetic leverage with a stablecoin liquidity pool, the system is highly capital-efficient, enabling access to a wide range of assets and leverage levels up to 500x. Avantis also introduces advanced risk management features, allowing LPs to fine-tune their exposure with time and risk parameters, effectively turning them into sophisticated market makers, while the underlying leverage engine is built to be composable so other protocols can integrate and expand on it.
