S-AMM

Algorithm

S-AMMs, or Slope-AMM, represent a novel automated market maker design prioritizing capital efficiency through dynamic fee adjustment based on the slope of the liquidity pool’s price curve. This contrasts with constant product AMMs by actively managing impermanent loss exposure, particularly in volatile markets, by incentivizing liquidity provision around the current market price. The core innovation lies in a continuously adapting fee structure, increasing fees as the pool deviates from equilibrium, thereby discouraging large trades that exacerbate slippage and protecting liquidity providers. Consequently, S-AMMs aim to offer tighter spreads and reduced capital requirements compared to traditional AMMs, enhancing overall market liquidity and trading efficiency.

Meaning ⎊ Lyra is an options AMM that uses a Black-Scholes-based pricing model to dynamically adjust for volatility and delta skew, ensuring liquidity providers are accurately compensated for the specific risk they underwrite.
