## Invariant Models

Invariant models in the context of decentralized finance and derivatives refer to mathematical frameworks that maintain a constant relationship between assets within a liquidity pool, regardless of trading volume. These models, most famously exemplified by the constant product formula, ensure that the product of the quantities of two tokens remains fixed during a swap.

By enforcing this rule, the model inherently dictates the price of assets based on the ratio of their reserves. This mechanism facilitates automated market making without the need for a traditional order book.

Invariant models are foundational to decentralized exchanges, allowing for continuous liquidity provision and algorithmic price discovery. They rely on the protocol physics of the underlying blockchain to ensure atomic settlement.

However, these models are susceptible to impermanent loss, a risk inherent to providing liquidity in a volatile market. Quantitative analysis of these models is essential for managing the risk-reward profile of liquidity providers.

By maintaining a predictable mathematical invariant, these protocols reduce the complexity of market microstructure for retail participants.
