What Is Slippage in Crypto Trading
If you have ever traded on a decentralized exchange, you have likely encountered slippage. Understanding what is slippage in crypto trading is essential for anyone who wants to trade effectively and avoid losing money to price differences, front-running bots, or hidden token taxes. This guide explains slippage from the ground up, covers the common causes, and provides practical strategies to minimize its impact on your trades.
Understanding Slippage in Crypto
Slippage is the difference between the price you expect to pay for a token and the price you actually pay when the transaction executes. On centralized exchanges with deep order books, slippage is usually minimal for standard trade sizes. But on decentralized exchanges that use automated market makers (AMMs), slippage is a fundamental part of how trading works.
AMMs like Uniswap, PancakeSwap, and Raydium use mathematical formulas to determine prices based on the ratio of tokens in a liquidity pool. When you make a trade, you change that ratio, which changes the price. The larger your trade relative to the pool size, the more the price moves against you. This is called price impact, and it is a form of predictable slippage that you can calculate before executing the trade.
Types of Slippage
- Price impact slippage: Caused by the size of your trade relative to the liquidity pool. Larger trades in smaller pools cause more slippage.
- Market movement slippage: The price changes between when you submit the transaction and when it confirms on the blockchain. More common during volatile markets.
- Front-running slippage: MEV bots detect your pending transaction and execute trades before and after yours (sandwich attacks), causing you to receive a worse price.
What Causes High Slippage
Several factors contribute to high slippage. Understanding them helps you anticipate and avoid situations where you would lose a significant amount to price differences.
- Low liquidity pools with small amounts of tokens locked
- Large trade sizes relative to available liquidity
- High network congestion causing delayed transaction confirmation
- Volatile market conditions with rapidly changing prices
- Token contracts with built-in transaction taxes (buy/sell fees)
- MEV bots and sandwich attacks targeting your transaction
Tokens with built-in taxes are a particularly common source of unexpected slippage. If a token has a 5% buy tax and a 5% sell tax, you need to set your slippage tolerance to at least 5% for the transaction to succeed. Some malicious token contracts hide extremely high taxes that only become apparent when you try to trade. Use Coinibi Token Checker to check the actual buy and sell tax on any token before trading.
Slippage Tolerance Settings Explained
Every DEX allows you to set a slippage tolerance, which is the maximum percentage of price difference you are willing to accept. If the actual slippage exceeds your tolerance, the transaction will fail and revert (you still pay the gas fee for the failed transaction). Setting the right slippage tolerance is a balance between ensuring your trades execute and protecting yourself from excessive losses.
Recommended Slippage Settings
- Major pairs (ETH/USDC, BTC/USDT): 0.1% to 0.5%
- Mid-cap tokens with good liquidity: 0.5% to 1%
- Low-cap tokens with thin liquidity: 1% to 3%
- Tokens with transaction taxes: Tax percentage + 0.5%
Be extremely cautious if a token requires more than 5% slippage. This often indicates hidden taxes or suspicious contract behavior.
How to Minimize Slippage
- Trade on pools with deep liquidity. The more liquidity in the pool, the less price impact your trade will have. Check pool depth before trading.
- Break large trades into smaller ones. Instead of making one large swap, split it into several smaller transactions to reduce price impact per trade.
- Use DEX aggregators. Aggregators like 1inch or Jupiter split your trade across multiple liquidity sources to find the best overall price.
- Trade during low congestion periods. Network congestion slows transaction confirmation, increasing the window for price changes. Trading during off-peak hours reduces this risk.
- Use MEV protection. Some DEXes and wallet providers offer MEV protection that routes your transaction through private mempools, preventing sandwich attacks by front-running bots.
- Set appropriate slippage tolerance. Do not set slippage higher than necessary. Start low and increase only if transactions fail.
Slippage as a Warning Sign
Unusually high slippage requirements can be a red flag indicating a problematic token. If a token requires 10%, 20%, or even 50% slippage to trade, the contract likely has built-in taxes that are eating into your trade value. Some scam tokens use this mechanism to extract value from every transaction, slowly draining traders while enriching the deployer through tax collection.
Before increasing slippage beyond 5%, always check the token with Coinibi Rug Radar to understand why high slippage is needed. If the high slippage is due to extreme taxes in the contract, reconsider whether the trade is worth making. Refer to our DeFi safety guide for more tips on trading safely on decentralized exchanges.

Frequently Asked Questions
What does slippage mean in crypto?+
Slippage in crypto refers to the difference between the expected price of a trade and the actual price at which the trade executes. It occurs because the price can change between the moment you submit a transaction and when it is confirmed on the blockchain. Slippage is especially common on decentralized exchanges where liquidity can be thin and prices are determined by automated market maker formulas.
What is a good slippage tolerance setting?+
For most trades on major token pairs with good liquidity, a slippage tolerance of 0.5% to 1% is appropriate. For newer or lower-liquidity tokens, you may need to increase it to 2-5%. Some tokens with built-in transaction taxes require slippage tolerance equal to or greater than the tax percentage. Setting slippage too low causes failed transactions, while setting it too high exposes you to front-running and sandwich attacks.
Why does my DEX trade keep failing due to slippage?+
Trades fail due to slippage when the price moves beyond your tolerance setting between submission and execution. This commonly happens with low-liquidity tokens, during high network congestion, or when trading tokens with built-in transaction taxes. Try increasing your slippage tolerance slightly, trading in smaller amounts, or waiting for lower congestion periods.
Can slippage be used to scam traders?+
Yes, some scam tokens require unusually high slippage tolerance (10-50% or more) to execute trades. This is often a sign that the token has extremely high hidden taxes built into the contract. Before setting high slippage, check the token contract for buy and sell taxes using a tool like Coinibi Token Checker. If a token requires more than 5% slippage, investigate the reason carefully before trading.
