Derive is an automated market maker (AMM) for options, allowing traders to buy and sell options on cryptocurrencies from a pool of liquidity. Liquidity providers (LPs) deposit sUSD (a stablecoin) into one of the asset-specific Derive Market Maker Vaults (MMVs). This liquidity is used to create two-way (buy and sell) options markets for the asset that the vault holds (e.g. ETH Market Maker Vault LPs quote options on ETH). LPs deposit liquidity into the vault to receive the fees paid when options are traded. Traders use Derive to trade options, either buying options from or selling options to the MMV. They pay fees (in the form of the market-making spread) to LPs, as payment for their liquidity.
