AMM
What is an Automated Market Maker (AMM)?
Automated Market Maker (AMM) is a type of decentralized exchange (DEX) protocol that allows users to trade cryptocurrencies directly with a liquidity pool, rather than relying on traditional order books. Instead of matching buyers and sellers, AMMs use smart contracts and mathematical formulas to automatically set prices and execute trades.
How Does an AMM Work?
Liquidity Pools: AMMs rely on liquidity pools, which are collections of funds provided by users (called liquidity providers or LPs). These pools contain pairs of tokens (e.g., SEGA/USDC) that traders can swap between.
Pricing Mechanism: AMMs use a mathematical formula to determine the price of assets in the pool. The most common formula is the Constant Product Market Maker model (popularized by Uniswap), which follows the equation:
x×y=k
Here, x and y represent the quantities of two tokens in the pool, and k is a constant. As traders swap one token for another, the ratio of the tokens changes, and so does the price.
No Order Books: Unlike centralized exchanges, AMMs don’t use order books. Instead, trades are executed directly against the liquidity pool, ensuring continuous liquidity and eliminating the need for buyers and sellers to match orders.
Liquidity Providers (LPs): Users who deposit tokens into the liquidity pool earn fees from trades that occur in the pool. These fees are distributed proportionally to LPs based on their share of the pool
Key Benefits of AMMs:
Decentralization: AMMs operate on blockchain networks, removing the need for intermediaries.
Accessibility: Anyone can become a liquidity provider and earn fees.
Continuous Liquidity: Trades can happen 24/7 without relying on market makers or order books.
Permissionless: Users can trade and provide liquidity without needing approval from a central authority.
