Zero trading fees sound like a dream, but the reality is more nuanced. We break down the best DEXs for near-zero-cost swaps — Uniswap, Jupiter, and Raydium — and explain how gas fees, spreads, and token incentives actually work so you can trade smarter.
The promise of zero trading fees is one of the most seductive hooks in crypto. Who wouldn't want to swap tokens without paying a cut to the exchange? But here's the thing: "zero trading fees" rarely means "zero cost." There's always gas, spreads, or some other mechanism at play. Let's cut through the marketing and look at the exchanges that genuinely get closest to fee-free trading.
Most centralized exchanges (CEXs) charge maker/taker fees — typically 0.1% per trade or less for high-volume users. Some, like Bybit and MEXC, offer zero-fee promotions on specific pairs or for makers only.1 But those promotions come with fine print: limited pairs, time-bound campaigns, or spreads that widen to compensate.
Decentralized exchanges (DEXs) take a different approach. They don't charge a platform trading fee at all — instead, you pay network gas fees (the cost of settling a transaction on-chain) and a small spread built into the automated market maker (AMM) formula. On low-cost chains like Solana, that gas fee can be fractions of a cent.
Here are the three exchanges that do this best.
Uniswap pioneered the automated market maker model on Ethereum. There's no order book, no maker/taker fee structure — just a direct swap against a liquidity pool. Uniswap's protocol fee is 0% for most swaps (it was turned off for years and only recently re-enabled at 0.01–0.02% on select pools).1
What you actually pay: Ethereum gas fees, which can range from $1 to $50+ depending on network congestion. On Layer 2s like Arbitrum or Optimism, gas drops to pennies.
| Spec | Detail |
|---|---|
| Trading Fee | 0% (protocol fee off for most pools) |
| Gas Cost | $1–$50 (Ethereum L1); <$0.10 (L2s) |
| Chains | Ethereum, Arbitrum, Optimism, Polygon, Base |
Best for: traders who already hold ETH and want access to the deepest liquidity across Ethereum and its L2s.
Jupiter isn't a single DEX — it's a swap aggregator on Solana that routes your trade across every liquidity source on the network (Raydium, Orca, Meteora, etc.) to find the best price and lowest fees.1 It charges 0% platform fees and makes no money from your trade.
What you actually pay: Solana gas fees — typically $0.0002 to $0.01 per transaction. That's it. No spread markup, no hidden fee.
| Spec | Detail |
|---|---|
| Trading Fee | 0% (no platform fee) |
| Gas Cost | ~$0.0002–$0.01 (Solana) |
| Chains | Solana |
Best for: active traders who want the cheapest possible swaps on the fastest chain. Jupiter's routing also means you almost always get the best available price.
Raydium is one of the largest automated market makers on Solana. Like Uniswap, it charges no platform trading fee — you pay only Solana gas and the small spread inherent to the AMM pool.1 Raydium also offers concentrated liquidity pools (CLMMs), which can reduce slippage and improve pricing for larger trades.
What you actually pay: Solana gas fees (~$0.0002–$0.01) plus the AMM spread (typically 0.01–0.05% depending on the pool).
| Spec | Detail |
|---|---|
| Trading Fee | 0% (no platform fee) |
| Gas Cost | ~$0.0002–$0.01 (Solana) |
| Chains | Solana |
Best for: liquidity providers and traders who want deep Solana-native pools with concentrated liquidity options.
| Feature | Uniswap | Jupiter | Raydium |
|---|---|---|---|
| Trading Fee | 0% | 0% | 0% |
| Gas Cost | $1–$50 (L1) / <$0.10 (L2) | ~$0.0002–$0.01 | ~$0.0002–$0.01 |
| Chains | Ethereum + L2s | Solana | Solana |
If they're not charging you, how do they stay in business? A few common models:
x*y=k) means you always buy slightly above the mid-price and sell slightly below it. That spread is captured by liquidity providers, not the protocol — but it's still a cost to you.If you want genuinely low-cost trading, DEXs on Solana are the clear winner — Jupiter and Raydium get you near-zero fees with gas measured in fractions of a cent. Uniswap on Ethereum L1 is only worth it for larger trades where gas is a small percentage. And "zero-fee" CEX promotions? Read the fine print — the spread usually gets you.
