Cega is an alternative options protocol built on the Ethereum, Solana, and Arbitrum chains, offering three types of products: option pool, bond option pool, and leverage option pool. The core logic is that users sell options by depositing USDC into the liquidity pool. Within a specific range of the underlying asset's price decline, there is no principal loss, and users can also earn premiums from market makers, making it more akin to yield-generating products.
