PancakeSwap is the dominant DEX on BNB Chain and has expanded to multiple chains. It offers AMM trading, concentrated liquidity (V3), yield farming, lotteries, NFTs, and prediction markets. As the gateway to BNB Chain DeFi, PancakeSwap processes billions in monthly trading volume with lower fees than Ethereum-native DEXs.
Curve Finance specialises in low-slippage swaps between similarly priced assets — stablecoins (USDT/USDC/DAI), wrapped tokens (WBTC/renBTC), and liquid staking derivatives (stETH/ETH). Its StableSwap invariant formula is specifically designed for pegged assets, offering much tighter spreads than constant-product AMMs. The CRV wars and vote-escrow tokenomics (veCRV) created an influential governance and bribery meta-game across DeFi.
Orca is a user-friendly DEX on Solana known for its clean interface and concentrated liquidity pools (Whirlpools). It prioritises capital efficiency and ease of use over complexity. Orca has become one of the most-used DEXs on Solana by volume.
Uniswap is the largest decentralised exchange by volume and the pioneer of the Automated Market Maker (AMM) model. Uniswap V3 introduced concentrated liquidity, allowing LPs to allocate capital within custom price ranges for dramatically improved capital efficiency. Uniswap V4 (upcoming) introduces hooks — plugins that allow developers to customise pool behaviour.
Aerodrome is the leading DEX on Base (Coinbase's L2), forked from Velodrome on Optimism. It uses the ve(3,3) model where voters direct emissions to liquidity pools, creating flywheel incentives for deep liquidity. Aerodrome has captured the majority of Base's DEX volume and TVL since launch.
