Lyra is an automated market maker (AMM) for options, allowing traders to buy and sell options on cryptocurrencies from a pool of liquidity.

LPs deposit liquidity into the vault to receive the fees paid when options are traded. Traders use Lyra 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.
