How Lyra Finance (LYRA) Works
Lyra Finance has two key user groups: liquidity providers and options traders. Liquidity providers deposit sUSD or USDC into one of the asset-specific Market Maker Vaults (MMV) to receive trading fees, while traders use Lyra to trade options.
To price options, Lyra Finance uses the Black-Scholes model, which calculates the price based on the asset price, strike price, risk-free interest rate, time to expiry, and implied volatility. The AMM adjusts implied volatility for each strike and expiry based on supply and demand to converge to a market-clearing value.
To protect existing LPs, various deposit/withdrawal circuit breakers are used. Moreover, a multisig under the control of two core contributors and five members of the council can approve deposits manually only when they have been signaled for a sufficient period of time. This is to make sure that the circuit breaker doesn't stop funds from entering the pool for too long. The goal is to keep the MMV close to delta-neutral, so fluctuations in PNL are reduced for LPs.
