RISQ protocol is a decentralized exchange for on-chain option trading based on Binance smart chain, and has an automatic market maker model. It has recently been successfully deployed on AVAX and POLYGON chains. RISQ is suitable for non-professionals to use in fund management, but also to meet the professional needs of hedge fund managers. The smart contract contains the fund's investment strategy and guidelines, which will be implemented exactly according to the code. RISQ can handle fully recognized on-chain puts and calls in liquidity pools. The RISQ holder has paid the option settlement fee and the LP award is issued along with the option price.
