Slippage is a common yet often misunderstood phenomenon in cryptocurrency trading. While the crypto market offers vast opportunities for investment, it also carries significant risks—some obvious, like hacks and scams, and others more subtle, like slippage. Understanding this concept is crucial for traders aiming to protect their capital and improve execution accuracy.
In this guide, we’ll explore what slippage is, why it happens, how to calculate it, and most importantly, practical strategies to minimize or avoid it—whether you're trading on centralized exchanges (CEX) or decentralized platforms (DEX). We’ll also examine its real-world impact and provide actionable insights backed by market dynamics.
What Is Slippage?
Slippage occurs when the executed price of a trade differs from the expected price at the time of order placement. This discrepancy can happen during periods of high volatility or low liquidity and is especially common in fast-moving markets like cryptocurrencies.
For example, if you place a market order to buy Bitcoin at $20,000 but end up paying $20,050 due to rapid price movement, that $50 difference is slippage. The same applies when selling—slippage might result in receiving less than anticipated.

Crucially, slippage isn't always negative. In some cases, traders benefit from positive slippage, where the executed price is better than expected. However, relying on favorable slippage is risky and unpredictable.
To gain control over execution prices, many traders use limit orders, which ensure a specific price or better. While effective at eliminating unwanted slippage, limit orders come with a trade-off: they may not execute at all if market prices don’t reach the specified level.
Why Does Slippage Happen?
Two primary factors contribute to slippage: high volatility and low liquidity. These elements are deeply embedded in the nature of crypto markets and amplify the chances of price deviation between order submission and execution.
High Volatility
Cryptocurrencies are known for their price swings. During news events, macroeconomic announcements, or sudden market shifts, prices can change dramatically within seconds. If your trade takes even a fraction of a second to process, the final price may differ significantly from the quoted one.
Low Liquidity
Liquidity refers to how quickly an asset can be bought or sold without causing a major price change. On less popular trading pairs or smaller exchanges, there may not be enough buyers or sellers at a given price point. When an order exceeds available depth on the order book, it "eats through" multiple price levels, resulting in slippage.
For instance, placing a large buy order on a thinly traded altcoin could push the price up as each available sell order is filled at incrementally higher prices.
How Slippage Works: A Real Example
Imagine you decide to purchase 1 BTC when the current market price shows $20,000. You submit a market order, but due to network delays or sudden demand spikes, your order executes at $20,050. That $50 gap is negative slippage.
Conversely, suppose liquidity suddenly increases below your target—perhaps due to a whale placing a massive sell order. In that case, your buy order might execute at $19,950 instead. This would be positive slippage, saving you $50.
While small differences may seem negligible for casual traders, they compound over time—especially for frequent or high-volume traders.
How to Calculate Slippage
Slippage can be measured in absolute terms (e.g., dollars) or as a percentage:
- Absolute Slippage: Final Price – Expected Price
Example: $20,050 – $20,000 = $50 - Percentage Slippage: (Slippage Amount / Expected Price) × 100
Example: ($50 / $20,000) × 100 = 0.25%
This calculation helps assess performance across trades and evaluate exchange efficiency.
What Is Slippage Tolerance?
Most crypto trading platforms allow users to set a slippage tolerance—a threshold defining how much price deviation they’re willing to accept. For example, setting a 1% tolerance means your trade will only execute if the price remains within ±1% of your expected value.
DEXs like Uniswap automatically display estimated output ranges based on your chosen slippage setting. If actual prices move beyond this range during transaction processing, the trade reverts to prevent excessive loss.

Slippage in DEXs (Decentralized Exchanges)
Decentralized exchanges operate differently from centralized ones. Instead of instant matching engines, DEXs rely on smart contracts and blockchain confirmations—introducing latency between order placement and settlement.
This delay increases slippage risk, especially on congested networks like Ethereum. Additionally, automated market makers (AMMs) adjust prices based on trade size and pool reserves, further influencing execution outcomes.
Even with accurate pricing models, temporary network delays mean prices can shift before confirmation—making slippage more frequent on DEXs than CEXs.
How to Reduce Slippage on DEXs
While eliminating slippage entirely on DEXs is nearly impossible, several strategies help mitigate its impact:
Pay Higher Gas Fees
Transactions on blockchains like Ethereum are processed in sequence based on gas fees. By paying higher fees, your transaction gains priority in the validation queue, reducing execution lag and exposure to price changes.
Tools like Etherscan’s gas tracker help determine competitive fee levels during peak times.
Trade on Layer 2 Networks
Layer 2 solutions such as Polygon offer faster and cheaper transactions by processing them off the main chain (Layer 1). Since these networks confirm trades quicker, they reduce the window for price fluctuations.
Popular DEXs like QuickSwap (built on Polygon) enable smoother trading experiences with lower slippage compared to their Ethereum-based counterparts.
How to Limit Slippage on CEXs
Centralized exchanges offer more tools to manage slippage effectively:
Use Limit Orders
Instead of market orders, place limit orders to specify the exact price you're willing to pay or receive. While this doesn’t guarantee execution, it ensures no adverse slippage occurs.
Avoid High-Volatility Periods
Schedule trades outside major market events—such as Federal Reserve announcements or major crypto news releases—to reduce unexpected price swings.
Split Large Orders
Break large trades into smaller chunks executed over time. This reduces market impact and avoids depleting order book depth too quickly.
The Impact of Slippage on Crypto Trading
The effect of slippage varies by trader type:
- Small Retail Traders: May barely notice a 0.25% slippage on occasional trades.
- High-Frequency Traders: Even minor slippage can erode profits rapidly when compounded across hundreds of daily trades.
- Institutional Traders: For large-volume transactions, a 0.5% slippage could mean tens of thousands in losses per trade.
Over time, consistent slippage eats into returns—making it essential to adopt preventive measures regardless of trading scale.
Frequently Asked Questions (FAQ)
What causes slippage in crypto trading?
Slippage primarily results from high market volatility and low liquidity. Rapid price movements or insufficient order book depth cause executed prices to differ from expected values.
Can slippage be completely avoided?
Only partially. Using limit orders on CEXs eliminates unwanted slippage, but trades may not fill. On DEXs, setting tight slippage tolerance helps—but increases failed transaction risks.
Is positive slippage common?
Positive slippage occurs but is unpredictable. Relying on it isn't a sound strategy; focus instead on minimizing negative slippage through proper order types and timing.
How does network congestion affect slippage?
Congestion slows transaction confirmations—especially on Ethereum—increasing the time gap between order submission and execution. This raises exposure to price changes and thus slippage risk.
Should I always set low slippage tolerance?
Not necessarily. Too low (e.g., 0.1%) may lead to frequent failed trades during volatile conditions. A 0.5%–1% tolerance balances execution success and cost control for most users.
Does slippage affect all cryptocurrencies equally?
No. Major coins like BTC and ETH have deeper liquidity and lower slippage. Smaller altcoins with thin order books suffer more pronounced slippage, especially on large trades.
