Meet the Big Three DEX: Uniswap, Curve, and SushiSwap Explained

ByL

Uniswap, Curve, and SushiSwap are three of the biggest names in the decentralized exchange world, and together they give a good snapshot of how on‑chain trading actually works. Understanding them helps everyday learners see where most DeFi swapping and liquidity action really happens.

Uniswap: the default DEX

Uniswap is the blue‑chip DEX on Ethereum, using automated market maker (AMM) pools so anyone can swap tokens or provide liquidity. For beginners, it is often the first place to see real on‑chain trades, gas fees, and how liquidity pools generate yield.​

Curve: stablecoin specialist

Curve focuses on like‑for‑like assets such as stablecoins or liquid staking tokens, using special curves to minimize slippage. For learners, Curve explains why different pool designs exist and how “safer” yield can come from low‑volatility pairs rather than speculative tokens.​

SushiSwap: community fork turned ecosystem

SushiSwap started as a community fork of Uniswap but grew into a multi‑chain DEX with extra features like farming and launchpads. It shows how open‑source DeFi can be copied, remixed, and expanded across many blockchains.

​Since we have talked about both Layer 2 (L2) and decentralized exchanges (DEXs), it is worth tying the two together. L2 networks exist largely to make DEX trading cheaper, faster, and more scalable, while still using Ethereum as the secure settlement layer. Many of the busiest DeFi apps on L2 today are DEXs, including Uniswap on Arbitrum, Optimism, and Base.
