An automated market maker is an algorithmic trading mechanism that replaces traditional order book matching with liquidity pool contracts governed by a mathematical bonding curve.
Liquidity providers deposit pairs of tokens into a pool, and the AMM formula determines the exchange rate based on the ratio of reserves. The constant product formula (x * y = k) is the most common variant, ensuring that trades shift the price smoothly along the curve.
In bostrom and the cyber ecosystem, the AMM operates through the DEX module, enabling permissionless swaps between network tokens. Any neuron can provide liquidity or execute trades without relying on a centralized exchange.
Price discovery emerges from arbitrage: when the AMM price diverges from external markets, traders profit by rebalancing the pool, pushing the price back toward equilibrium. This self-correcting mechanism operates continuously and autonomously.
Liquidity providers earn fees proportional to their share of the pool, creating an incentive to supply capital. The trade-off is impermanent loss, where price divergence between deposited assets reduces the value of the position relative to simply holding.
AMMs form the foundational DeFi primitive for token economies, enabling on-chain price discovery and liquidity for any asset pair in the cybergraph ecosystem.
