Technical Details
Key components include:
-
Constant Product Formula: x * y = k pricing mechanism where token quantities maintain constant product

Liquidity Pools: Smart contracts holding paired token reserves deposited by liquidity providers
-
LP Tokens: Receipts representing liquidity provider shares and earning trading fees
-
Slippage: Price impact from large trades relative to pool size
Major Protocols
Uniswap (Ethereum), SushiSwap, Curve Finance (stablecoins), PancakeSwap (BNB Chain), and Balancer (weighted pools).
Advantages and Risks
Advantages include 24/7 liquidity, permissionless access, and decentralization. Risks include impermanent loss for LPs, smart contract vulnerabilities, and slippage on large trades.
Metaverse Applications
AMMs enable trading of virtual land tokens, in-game assets, and metaverse project governance tokens.
