Experiencing a transaction error while trading cryptocurrencies can be frustrating. The "insufficient_output_amount" error on decentralized exchanges like PancakeSwap and Uniswap is a common issue, but it is usually simple to resolve. This error typically occurs due to market volatility and liquidity conditions, not a fault of your own.
Understanding why this happens and how to adjust your settings will allow you to complete your trades successfully. This guide provides clear, step-by-step solutions to bypass this error and continue your trading activities without significant interruptions.
What Causes the "Insufficient Output Amount" Error?
This error is primarily triggered by two related factors: slippage tolerance and liquidity. Slippage is the difference between the expected price of a trade and the actual price at which it is executed. For instance, if you anticipate receiving 1.0 token for your swap but only get 0.9, the slippage is 10%.
Slippage occurs because cryptocurrency prices are extremely volatile. The market is constantly moving as users buy and sell, which can change a token's value between the moment you initiate a transaction and when it is finalized on the blockchain.
Low liquidity in a trading pair can exacerbate this issue. Liquidity refers to how easily an asset can be bought or sold without affecting its price. A token pair with low liquidity is more prone to large price swings, making it harder to execute a trade at the expected rate.
If your set slippage tolerance is too low, the transaction will fail to protect you from receiving significantly less value than you anticipated. The exchange automatically cancels the trade to prevent a bad outcome.
How to Resolve the Error on PancakeSwap
PancakeSwap has a default slippage tolerance that is often too low for many market conditions. Here are the most effective methods to fix the error on this platform.
Refresh the Web Page
Sometimes, a simple page refresh can resolve temporary glitches. Close the error message, refresh your browser, and try the transaction again. If the error persists, proceed to adjust your slippage settings.
Adjust Slippage Tolerance Gradually
The most controlled method is to increase your slippage tolerance in small increments.
- Navigate to the PancakeSwap exchange and select the tokens you wish to swap.
- Click the settings (gear) icon to open the settings panel.
- Locate the "Slippage tolerance" field. The default is usually 0.5% or 0.8%.
- Increase this value by 1%, for example, to 1.8%, and attempt the swap again.
- If the transaction fails, continue increasing the slippage by 1% until it succeeds.
This method requires patience but helps you find the lowest possible slippage setting that allows your trade to execute, maximizing the value you receive.
Use a Higher Slippage Setting
For a faster solution, many users find that setting slippage to 12% or 15% works immediately.
- On the PancakeSwap swap interface, open the settings panel.
- In the "Slippage tolerance" field, manually enter "12" or "15".
- Confirm the settings and execute your swap.
You may see a warning that your "transaction may be front-run." You can typically dismiss this warning and proceed. While this method is quicker, be aware that accepting higher slippage means you are willing to accept a larger difference between the expected and actual trade price.

How to Resolve the Error on Uniswap
The process for Uniswap is very similar to PancakeSwap, as both are automated market maker (AMM) decentralized exchanges.
Refresh the Page and Retry
Begin with the simplest solution. Refresh your browser and attempt the token swap again to rule out a temporary issue.
Incremental Slippage Increase
If refreshing doesn’t work, adjust your slippage settings step-by-step.
- On the Uniswap swap page, click the settings (gear) icon.
- A pop-up will appear. Find the field for setting a custom slippage tolerance.
- Increase the percentage from its default value by 1% and confirm the swap.
- Repeat this process, increasing by 1% each time, until the transaction is successful.
Apply a High Slippage Percentage
To bypass the error immediately, set a high slippage tolerance.
- Open the transaction settings on the Uniswap interface.
- Type "12" or "15" into the custom slippage percentage field.
- Save the settings and confirm your swap.
This will likely overcome the error caused by market volatility, though it comes with the same trade-off of potentially higher price impact.
Frequently Asked Questions
What does "insufficient_output_amount" mean?
This error means the platform could not execute your trade at a price that was close enough to your expected amount. It's a protective measure that cancels the transaction to prevent you from receiving far less cryptocurrency than you anticipated due to price movements before the trade was confirmed.
Why do I keep getting this error even with high slippage?
If adjusting slippage doesn’t work, the issue might not be the market. The problem could lie with your Web3 wallet (like MetaMask or Trust Wallet), a weak internet connection, or a browser issue. Try reinstalling your wallet extension, reconnecting it to the dApp, using a different browser, or ensuring you have a stable internet connection.
Are certain cryptocurrencies more likely to cause this error?
Yes, tokens with high volatility or low liquidity are more prone to triggering this error. This often includes new tokens, meme coins, or any asset experiencing rapid buying and selling pressure. Even popular tokens like ETH can cause errors during periods of extreme market activity.
Is it safe to set a very high slippage tolerance?
While it makes a successful transaction more likely, it also increases your risk. A high slippage setting means you are willing to accept a worse exchange rate. Always be cautious, as very high slippage could result in significant losses, especially on low-liquidity tokens.
Can this error occur on other decentralized exchanges?
Yes, the "insufficient_output_amount" error is not unique to PancakeSwap or Uniswap. Any decentralized exchange that uses an automated market maker (AMM) model can produce this error because they all handle slippage in a similar way to protect users from extreme market moves.
What is the best permanent fix for this issue?
There is no single permanent fix, as market volatility is inherent to cryptocurrency trading. The best approach is to understand how slippage works and learn to adjust your settings based on current network congestion and the specific tokens you are trading. Always check the liquidity of a trading pair before initiating a large swap.
Conclusion
The "insufficient_output_amount" error is a standard part of interacting with decentralized finance (DeFi) platforms. It serves as a necessary protection against unfavorable trades. By understanding the role of slippage and liquidity, you can quickly troubleshoot this problem. Whether you choose to adjust your settings gradually or use a higher predefined value, you now have the knowledge to bypass this error and continue your trading journey with confidence. Staying informed is the best tool for navigating the dynamic world of crypto swaps. 👉 Learn more about managing transaction settings
