Automated Market Maker Invariants

Algorithm

Automated Market Maker Invariants, fundamentally, represent the mathematical relationships that govern the pricing and liquidity provision within AMMs. These invariants, often expressed as equations, ensure that the pool’s total value remains constant, or adheres to a predictable curve, despite trading activity. A common example is the x y = k invariant in constant product AMMs, where x and y represent the quantities of two assets and k is a constant. Deviations from these invariants can signal arbitrage opportunities or inefficiencies within the market, prompting traders to rebalance the pool and restore equilibrium.
