What is an Automated Market Maker (AMM)?
An Automated Market Maker (AMM) is a type of decentralized exchange (DEX) that enables cryptocurrency trading without relying on a middleman or traditional order book. Instead of matching buyers with sellers, AMMs utilize liquidity pools—collections of tokens contributed by users. These pools operate through smart contracts that automatically determine token prices and facilitate trades.
Why are AMMs Important?
AMMs are significant because they provide seamless access to trading tokens, including those that might not be listed on major centralized exchanges. On networks like Solana, AMMs are particularly efficient due to the network’s high speed and low transaction fees. These features make trading on AMMs fast, cost-effective, and ideal for niche tokens like memecoins and NFTs.
How do AMMs Benefit Liquidity Providers?
Users who contribute tokens to an AMM’s liquidity pool, known as liquidity providers, earn a share of the transaction fees generated from trades within that pool. This incentivizes individuals to supply liquidity, ensuring smooth operation and robust trading activity.
Real Life Examples of AMMs
