Learn what slippage is in crypto trading, why it happens, how to minimize it on DEXs and CEXs, and what slippage tolerance settings mean in 2026.
What is Slippage? The Gap Between Expected and Actual Price
Slippage is the difference between the price you expect to pay for a cryptocurrency and the price you actually pay when your trade executes. It is an invisible cost that affects every trade, though its magnitude varies enormously depending on what you are trading, where you are trading it, and how large your trade is.
When you see Bitcoin quoted at $50,000 and place a market order, you almost certainly pay $50,001 or $50,002 on a liquid exchange. The slippage is tiny and barely matters. When you try to buy $50,000 worth of a small-cap token on a DEX with a shallow liquidity pool, you might end up paying $55,000 worth of the pool's counter-token because your trade itself moved the price ten percent before filling.
Slippage is not a fee that goes to the exchange. It is a market impact cost driven by supply and demand dynamics.
Why Slippage Happens: Order Books and Liquidity Pools
On centralized exchanges with order books, slippage occurs when your order size exceeds the available liquidity at the best price. If you want to buy $100,000 of a token but there are only $20,000 worth of offers at the current price, the remaining $80,000 fills at successively worse prices as your order works through the order book.
On DEXs using Automated Market Makers, slippage is mathematically determined by the pool size and the trade size. A trade representing one percent of a pool's liquidity will move the price roughly two percent. A trade representing ten percent of the pool will move the price dramatically more, following the curve determined by the AMM formula.
The key insight is that slippage is directly proportional to your trade size relative to available liquidity. Small trades in deep markets have minimal slippage. Large trades in shallow markets have severe slippage.
Slippage Tolerance Settings on DEXs
When you use a DEX like Uniswap or Curve, you set a slippage tolerance before executing a trade. This is the maximum percentage difference between the quoted price and the execution price you are willing to accept.
A slippage tolerance of 0.5 percent means your transaction will revert (fail) rather than execute if the price has moved more than 0.5 percent by the time your transaction confirms. This protects you from extreme price impact but may cause transactions to fail in fast-moving markets.
Setting slippage tolerance too low results in frequent transaction failures. Setting it too high exposes you to executing at a much worse price than expected, and also makes you vulnerable to MEV (Maximal Extractable Value) attacks called sandwich attacks, where bots detect your pending transaction and insert trades to profit from your generous slippage tolerance.
For stable pairs like USDC to USDT, 0.1 percent is appropriate. For volatile pairs, 0.5 to 1 percent is typical. For very low-liquidity tokens, higher settings may be necessary.
Minimizing Slippage in Practice
Several practical strategies help minimize slippage costs.
Breaking large trades into smaller pieces and executing them over time reduces the price impact of each individual trade. This is called splitting an order.
DEX aggregators like 1inch, Paraswap, and Jupiter (on Solana) automatically route your trade across multiple liquidity pools to find the best overall execution price and minimize slippage. For any trade over a few thousand dollars on a DEX, using an aggregator is almost always worth it.
Trading during periods of high liquidity reduces slippage. For major token pairs, liquidity tends to be deepest during peak trading hours when overlapping US and European sessions are active.
For very large trades, over-the-counter (OTC) desks provide liquidity directly without going through public markets, avoiding price impact entirely.
Slippage vs. Price Impact vs. Fees: Understanding All Three Costs
When evaluating the true cost of a trade, it is important to distinguish between three separate costs that are often confused.
Trading fees are the explicit percentage charged by the exchange or protocol, typically 0.1 to 0.3 percent on DEXs and 0.1 to 0.5 percent on CEXs. These are fixed and predictable.
Price impact is the amount your specific trade moves the market price. This is inherent to trading against a liquidity pool or order book and is directly related to your trade size and available liquidity.
Slippage is the difference between the expected price when you initiate the trade and the actual execution price, which may reflect both price impact and market movement during the time your transaction takes to confirm on-chain.
For large DeFi trades, price impact can dwarf trading fees. Always check the price impact warning displayed by most DEX interfaces before confirming significant trades.
Slippage: A Real Cost Worth Managing
Slippage is one of those trading costs that is easy to ignore but compounds significantly over time, particularly for active traders and those dealing in lower-liquidity tokens.
The practical habits that minimize slippage: use DEX aggregators for any significant on-chain trade, check liquidity depth before entering a position in any smaller token, use limit orders on CEXs rather than market orders for large trades, and set slippage tolerance thoughtfully on DEX interfaces.
Understanding slippage also helps you evaluate the true cost of DeFi participation and set realistic expectations about the returns from trading strategies that might look profitable on paper but lose substantially to execution costs in practice.
