AMM Architecture

Automated Market Maker architecture is a foundational framework in decentralized finance that replaces traditional order books with algorithmic liquidity pools. Instead of matching buyers and sellers directly, participants trade against a pool of assets locked in a smart contract.

The price of these assets is determined by a constant product formula, such as x times y equals k, where x and y represent the quantities of the two tokens in the pool. When a user buys one token, they add the other to the pool, shifting the ratio and automatically adjusting the price based on supply and demand.

This mechanism ensures continuous liquidity without the need for centralized intermediaries or market makers. AMMs rely on liquidity providers who deposit assets to earn trading fees, which incentivizes participation.

The architecture is highly efficient for small-to-medium trades but can be subject to slippage during high-volume volatility. It represents a paradigm shift in market microstructure by codifying price discovery into immutable, on-chain logic.

Security relies entirely on the robustness of the smart contract code and the underlying consensus mechanism.
