Financial Invariants

Formula

Financial invariants are mathematical relationships within a financial system that remain constant despite changes in market variables like price or volume. In the context of automated market makers (AMMs), the invariant formula defines the relationship between the quantities of assets in a liquidity pool. This formula ensures that the product of the asset reserves remains constant, thereby determining the price curve for trades. The design of this invariant is critical for defining the AMM’s behavior and its resilience to market shocks.
