Compare top DEXs: Uniswap ($4T volume), PancakeSwap ($6B TVL), Curve ($9B TVL), dYdX, Jupiter. AMM vs orderbook models. Zero KYC. Learn to swap tokens directly from your wallet.
What is a DEX?
A decentralized exchange (DEX) is a peer-to-peer platform where users trade crypto directly from their wallets without a central intermediary. No KYC required. No custody risk (you control your private keys). Built on smart contracts. Examples: Uniswap, Curve, PancakeSwap, dYdX, Jupiter.
Our team ran deposits, trades, and withdrawals on every exchange we review. Withdrawal speed and fee transparency varied more than expected.
DEX vs CEX Comparison
| Feature | DEX | CEX |
|---|---|---|
| KYC Required | No | Yes |
| Your Keys | Yes (self-custody) | No (CEX custody) |
| Trading Fees | 0.01%-0.50% | 0.49%-3.99% |
| Coins Available | Any ERC-20/token | Selected by exchange |
| Liquidity | Variable (pool-based) | High (market makers) |
| Speed | Slower (blockchain) | Instant |
AMM vs Orderbook Models
Automated Market Maker (AMM)
An AMM replaces order books with liquidity pools. Formula: x*y=k (Uniswap). Users deposit token pairs and earn trading fees. When you trade, the contract executes against the pool. Examples: Uniswap, Curve, PancakeSwap. Advantage: always liquid. Disadvantage: slippage on large trades.
Orderbook Model
An orderbook DEX matches buy/sell orders. Users post orders at specific prices. Only active pairs can trade. Examples: dYdX, Jupiter (Solana). Advantage: better prices (less slippage). Disadvantage: slower (depends on order flow).

Why Curve for Stablecoins?
Curve uses a custom formula optimized for assets with stable values (USDC, USDT, FRAX, crvUSD). Slippage is 100x lower than Uniswap for stablecoins. For example: swapping $1M USDC-USDT on Curve = 0.01% slippage vs Uniswap = 1-2% slippage.
Curve Governance (CRV Token)
CRV holders vote on pool incentives and fee allocation. Staking CRV earns protocol fees (3-15% APY). LPs earn trading fees + incentives (10-50% APY on popular pools).
dYdX: Derivatives DEX

FAQ
What is a decentralized exchange (DEX)?
A DEX is a peer-to-peer exchange with no central authority. Users trade directly from their wallets (MetaMask, etc.). No KYC required. No single point of failure. Examples: Uniswap (Ethereum), PancakeSwap (Binance), Curve (stablecoins), dYdX (derivatives). DEXs use smart contracts to facilitate trades. Lower fees (0.01%-0.50%) than centralized exchanges (0.49%-3.99%).
What is an AMM (Automated Market Maker)?
An AMM is a smart contract that replaces order books with liquidity pools. Users deposit token pairs (e.g., ETH+USDC) and earn trading fees. The contract executes trades against the pool using the formula x*y=k (Uniswap). Slippage increases with pool size. AMMs are user-friendly but less capital-efficient than orderbooks (dYdX, Jupiter).
What is an orderbook DEX?
An orderbook DEX matches buyers and sellers without liquidity pools. Users post buy/sell orders at specific prices. Only pairs with active orders can trade. dYdX and Jupiter use orderbook models. Better prices (less slippage) than AMMs but slower (liquidity dependent).
Which DEX has the lowest fees?
Curve: 0.04% trading fee (stablecoin swaps). Uniswap V3: 0.01%-0.50% (custom fee tiers). PancakeSwap: 0.01%-0.50%. dYdX: 0.02%. Jupiter: 0.025% (average). Layer 2 DEXs (Arbitrum, Optimism) are cheaper: gas is $0.01-0.05 vs $0.50-2 on Ethereum mainnet.
What is slippage and how do I minimize it?
Slippage is the difference between expected and actual price paid. Large trades cause more slippage. Minimize by: trading smaller amounts, using DEXs with high liquidity (Uniswap, Curve), using stablecoin-to-stablecoin pairs (Curve), or trading on L2s (cheaper gas = smaller minimum trades). Most DEXs let you set max slippage tolerance (0.1%-5%).
How do I provide liquidity and earn yield on a DEX?
Deposit equal values of two tokens into a liquidity pool (e.g., $500 ETH + $500 USDC on Uniswap). Earn a % of trading fees. APY varies: Uniswap 3-15%, Curve 5-40% (depending on pool), PancakeSwap 10-50%. Risk: impermanent loss (IL) if token prices diverge. Stablecoin pools (USDC-USDT) have low IL.
