1. What is AMM?
AMM stands for Automated Market Maker, a self-executing market-making tool that enables users to buy or sell assets on decentralized exchanges (DEX) without needing a counterparty. Unlike traditional exchanges that rely on buy/sell orders, AMMs use smart contracts and liquidity pools to automatically price and execute trades.
Key Features:
- Automation: AMMs operate via algorithms and smart contracts, eliminating human intervention.
- No Counterparty Required: Trades are executed directly against liquidity pools.
- Liquidity Providers (LPs): Users who deposit assets into pools earn fees from trades.
2. History of AMMs
- 2017: Bancor pioneered AMMs but lost traction due to lack of innovation.
- 2018: Uniswap launched with its simple
x*y=kpricing model, becoming a dominant DEX. - 2020: Sushiswap and Pancakeswap emerged, leveraging token incentives and multi-chain expansion.
- 2021: Curve Finance peaked with a $24B TVL, specializing in stablecoin swaps.
- 2023–Present: Advanced AMMs like Uniswap V3 and Ambient Finance introduced concentrated liquidity and hybrid models.
3. How AMMs Work
- Liquidity Pools: LPs deposit asset pairs (e.g., ETH/USDT) to enable trading.
- Pricing Algorithm: The
x*y=kformula (used by Uniswap) adjusts asset prices dynamically based on pool reserves. - Example: Swapping 0.1 ETH in a pool with 1 ETH and 1,000 USDT yields ~90.9 USDT, reflecting price slippage.
4. Types of AMMs
| Model | Formula | Use Case | Pros | Cons |
|---|---|---|---|---|
| Constant Product | x*y=k | Volatile assets | Universal support | High slippage |
| Concentrated | x*y=k | Large-cap assets | Capital efficiency | Manual price range updates |
| StableSwap | Hybrid | Stablecoins | Low slippage | Niche applicability |
