PancakeSwap holds a narrow lead over Uniswap for low-cost trading, favored for low network transaction costs on BNB Chain. For finding the absolute lowest overall fees, 1inch is the usual answer due to multi-chain routing.
There isn't one decentralized exchange (DEX) with the lowest fees in every situation. The cheapest option depends on which blockchain you're trading on, the tokens you're swapping, and the size of your trade.
The key distinction is that a DEX swap can involve three separate costs:
Trading fee: charged by the exchange or liquidity pool.
Network gas fee: paid to process your transaction on the blockchain.
Price impact and slippage: the potential cost of trading against available liquidity.
A DEX with zero or very low trading fees can still be more expensive overall if its network fees or price impact are high.
Lowest-fee DEXs to consider in 2026
1. Jupiter — Best for Solana swaps
(Best starting point)
Routes trades across Solana liquidity sources to seek competitive execution. Solana network fees are generally very low, though the underlying pool and any applicable platform fee still matter.
Offers low-fee liquidity pools and inexpensive transactions on BNB Chain. Fees vary by pool version and trading pair.

3. Curve Finance — Best for stablecoins
Specializes in assets with similar values, such as stablecoins. Its pools can offer very low swap fees, although gas costs depend on the network.
Website:
4. 1inch — Best for comparing swap routes
Aggregates liquidity from multiple DEXs to find competitive rates. Its advantage is potentially better execution, rather than guaranteeing the lowest total cost on every trade.

[Find my lowest-cost DEX]
My quick recommendation: Start by comparing Jupiter for Solana, PancakeSwap for BNB Chain, and 1inch for multi-DEX routing. For a fair comparison, look at the final amount you receive after all fees, not just the advertised trading fee.
The lowest-fee options break down across popular categories as follows:
Spot Swaps & Aggregators:
Jupiter (Solana): Operates as a leading Solana liquidity aggregator. While swap fees vary depending on the underlying route, Solana's network transaction fees are practically negligible (often less than $0.0025), making overall transaction overhead the lowest available for retail spot swaps.
If you can tell me whether you are planning to do spot token swaps or perpetual trading , and which blockchain network you prefer to use, I can help you find the exact platform with the lowest overall cost for your trade.
When looking for the cheapest decentralized exchanges (DEXs), total cost comes down to two components: protocol/trading fees charged by the platform and network gas/transaction fees charged by the underlying blockchain.
The most cost-effective DEXs span specific niches depending on whether you are swapping stablecoins, trading perpetuals, or using high-speed layer networks:
Curve Finance(Best for Stablecoins & Pegged Assets)
Trading Fee: ~ 0.0 4%(0.0 4%) base swap fee
Why it’s cheap: Curve uses a specialized AMM algorithm designed specifically for assets of equal value (like USDC/USDT or stETH/ETH). This minimizes price impact (slippage) alongside its ultra-low pool fee. Note: Gas fees depend on the network you use it on (Ethereum mainnet gas can be high, but deployments on L2s like Arbitrum or Optimism keep total costs minimal). You can check it out on Curve Finance.[](https://fensory.com/insights/protocols/curve)
Hyperliquid(Best for Perpetual/Order Book Trading)
The cheapest decentralized exchange (DEX) depends heavily on which blockchain you trade on, how much you trade, and whether you mean swap fees or total transaction costs.
There are three costs worth comparing:
Swap fee: The percentage of your trade charged by the exchange or liquidity pool.
Network gas: The blockchain fee for executing the transaction.
Extra trading costs: Aggregator fees, price impact, and slippage, which can make an apparently cheap swap more expensive.
For example, a DEX charging 0.05% on a swap may be cheaper than one charging 0.01% if the second requires much more expensive network transactions. The reverse can also be true for large trades.
Cheapest DEX options to check first
Based on current fee documentation and recent blockchain fee estimates, these are the strongest candidates to compare in October 2026.
1. Jupiter — Solana
(Best starting point for Solana)
Platform fee varies by token pair; documented examples range from 0% to 0.10% for ordinary pairs, with higher fees possible for newly launched tokens. Network fees are typically fractions of a cent.
Decentralized exchanges (DEXs) generally charge a protocol/trading fee (often ranging from 0.01% to 0.3% for standard spot swaps, or lower for specialized limit/perpetual orders), but the actual "transaction fee" heavily depends on the underlying blockchain network's gas costs. Layer-2 networks (like Arbitrum or Base) and high-throughput chains (like Solana) offer vastly cheaper overall transaction costs than mainnet Ethereum.
Here are the top decentralized exchanges and aggregators known for having some of the lowest trading and transaction overhead:
Curve Finance: Known especially for stablecoin and correlated-asset swaps, charging an exceptionally low baseline trading fee of around 0.04% per trade on its pools. When deployed on efficient L2s, overall transaction costs remain minimal.[](https://nownodes.io/blog/best-decentralized-exchanges-dexs-in-2026/)
Uniswap (on Layer-2s): While mainnet Ethereum Uniswap pools carry high gas fees, Uniswap deployed on networks like Arbitrum, Optimism, or Base offers variable pool fees starting as low as 0.01% alongside drastically reduced L2 transaction fees.[](https://cryptoslate.com/decentralized-exchanges/)
Note: Total transaction cost is always a combination of the DEX's swap/trading fee plus the underlying network gas fee. Always check current network congestion and slippage settings before executing trades. [](https://nownodes.io/blog/best-decentralized-exchanges-dexs-in-2026/)
If you want to narrow this down, let me know:
What blockchain network or layer you prefer to trade on
Whether you are trading spot tokens or perpetuals/derivatives
I can give you a more precise fee breakdown for your use case.
The cheapest decentralized exchange depends on which blockchain you trade on, the size of your swap, and whether you mean trading fees or total transaction costs. A DEX advertising 0% trading fees can still be expensive if the blockchain charges high gas fees.
For the lowest overall cost, I'd compare DEXs on low-fee networks such as Solana, BNB Chain, and Layer 2 networks like Base and Arbitrum, alongside established options on Ethereum.
There are three costs worth comparing:
Trading fee: The percentage taken by the DEX or liquidity pool.
Network fee (gas): The cost of processing your transaction.
Price impact and slippage: The value lost due to liquidity and price movement, especially on larger swaps.
DEXs worth comparing for the lowest fees
The following shortlist uses published fee schedules and current documentation available in October 2026. It is not a guaranteed live ranking: pool fees, network congestion, and the route selected can change the cheapest option.
1. Jupiter — Solana
Best for comparing routes across multiple Solana liquidity venues rather than assuming one pool is always cheapest.
Standard pools typically charge 0.25%; some pools have much lower tiers, including 0.005% for certain CPMM pools and 0.02% for its stablecoin-focused Stable AMM. Network fees are additional.
Best when you can access a genuinely low-fee pool with sufficient liquidity for your token pair.
Pool fees vary by market. Uniswap v3 supports tiers of 0.01%, 0.05%, 0.30%, and 1%, although the available and applicable tiers depend on the pool. The Uniswap Labs interface fee is currently 0%.
Best for trading established tokens on low-cost networks such as Base, where network gas is usually very inexpensive.
These are candidates, not a definitive live ranking: the cheapest route for a particular swap can change with liquidity, pool configuration, token pair, and network congestion.
Which blockchain is cheapest overall?
For ordinary swaps, the network itself can make a big difference. Recent 2026 estimates give this rough comparison:
Network
Indicative swap gas
DEXs to compare
Solana
Usually under $0.01
Jupiter, Raydium
Base
Roughly $0.002–$0.02
Uniswap
Arbitrum
Roughly $0.01–$0.05
Uniswap and other supported DEXs
Ethereum mainnet
Can be several dollars or more
Uniswap, Curve
These are indicative estimates, not guaranteed live quotes. Actual gas costs vary with transaction complexity and network conditions; pool fees are extra.
My recommendation
For Solana tokens: Start with Jupiter to compare execution routes, then inspect the quoted fees.
For Ethereum-compatible tokens: Compare Uniswap on Base with alternatives on the same chain.
For stablecoin swaps: Check Curve and other stablecoin pools for the exact pair.
For frequent or large trades: Compare the final amount received, not just the advertised fee percentage.
One important caveat: a DEX with a low advertised fee can still give you a worse deal because of slippage, thin liquidity, or token-specific transfer taxes.
Let me narrow it down
Which tokens and blockchain are you trading? That determines which exchanges are actually cheapest.
Trading fee: route-dependent · Network: usually very low
Jupiter is a swap aggregator that searches across Solana liquidity sources. Its cost depends on the pools and route used, so compare the final quoted output rather than assuming every swap is fee-free.
Website:
2. Raydium — Solana
Trading fee: 0.25% on common pools; some pools offer lower tiers · Network: very low
Raydium's published fee schedule includes CPMM pools starting at 0.005% and concentrated-liquidity pools starting at 0.01%. These lower tiers are pool-specific and don't apply to every trade.
Website:
3. Orca — Solana
Trading fee: pool-dependent, with tiers starting around 0.01% · Network: very low
A useful alternative for swaps between liquid token pairs. The actual pool fee and price impact matter more than the advertised minimum.
Website:
4. PancakeSwap — BNB Chain and other supported networks
Trading fee: some V3 pools start at 0.01% · Network: generally low on BNB Chain
A strong candidate for inexpensive swaps on BNB Chain. PancakeSwap's router can use different pool types and liquidity sources, so check the fee and route displayed for your particular trade.
Website:
5. Uniswap — Ethereum, Base, Arbitrum and other supported chains
Trading fee: V3 tiers include 0.01%, 0.05%, 0.30% and 1% · Network: varies by chain
Uniswap V4 also supports configurable pool fees. On Base or Arbitrum, transaction costs can be much lower than on Ethereum mainnet, although the pool fee and available liquidity still determine the best deal.
Website:
6. Aerodrome Finance — Base
Trading fee: pool-dependent · Network: typically low
Worth comparing for Base-native assets and stablecoin swaps. Stablecoin pools can be particularly cost-effective, but the pool's actual fee, liquidity, and quoted output should guide your choice.

$3.00
1.00%
$10.00
These are illustrative calculations, not live quotes. Network fees, price impact, token transfer taxes, and any additional routing fees are excluded.
My recommendation: Start with Jupiter for Solana trades, PancakeSwap for BNB Chain, and Aerodrome or Uniswap on Base. Compare the final amount of tokens you receive for the same input amount before confirming a swap. A lower advertised fee doesn't always mean a better price.
One question that would help me narrow this down: Which blockchain do you trade on most often?
