A smart-contract market design that quotes swaps from pool state and a specified pricing rule instead of matching a traditional order book. The formula, fees, liquidity range, oracle behavior, and risks are protocol and pool specific.
Supports: Uniswap documents the constant-product pool model, liquidity-provider exposure, and why a current pool price is not safe as an unprotected on-chain oracle.
Supports: Ethereum.org explains pool reserve-based exchange rates, liquidity-token ownership, swap execution, and minimum amounts for liquidity operations.
Supports: Ethereum.org describes Uniswap as an automated liquidity protocol using a constant-product formula and non-upgradeable contracts.
AMMs use mathematical formulas to price assets automatically without traditional order books
Liquidity providers deposit equal-value pairs of tokens and earn fees from each trade
The constant product formula x*y=k determines prices as the ratio of tokens in the pool changes
AMMs are the backbone of decentralized exchanges like Uniswap, Curve, and Balancer
A Uniswap ETH/USDC pool holds 1,000 ETH and $2M USDC. When someone buys ETH, the pool adds USDC and removes ETH, automatically adjusting the price upward based on the constant product formula.
A provider-calculated USD value of assets included in a DeFi protocol or chain at a stated time. The figure depends on contract coverage, asset prices, inclusion rules, and treatment of composable or bridged assets; it is not liquidity, safety, adoption, or revenue by itself.
An exchange design that uses blockchain transactions, smart contracts, or an onchain order book to match or execute trades. Custody, operator roles, access controls, fees, execution, and protections vary by protocol and jurisdiction.
The difference between an AMM liquidity position's value and the value of holding its deposited assets outside the pool at the same prices. It depends on the pool curve, price path, fees, range, token behavior, and withdrawal time; it is not a guaranteed temporary loss or yield forecast.
Assets supplied to a smart-contract market-making system so swaps can execute against its rules instead of a traditional order book. The assets, fees, price curve, liquidity shares, withdrawal conditions, and risks depend on the specific pool and protocol.
