# Pump.fun transactions failing due to slippage

An incorrect slippage setting is a common reason why Pump.fun trades don’t get copied.

We can confirm if our transaction failed due to slippage % by using tools like Solscan, where viewing the transaction signature reveals if slippage was the cause.

1. Go to [**solscan.io**](https://solscan.io) and search for your wallet.
2. Look for the failed transaction that occurred at the time of the trade. (*has a red sign next to it*)

3. Open the transaction and you will see one of the following errors: \
   \&#xNAN;***"Program Error: "Instruction #4 Failed - custom program error: slippage: Too much SOL required to buy the given amount of tokens"***\
   \
   \&#xNAN;*or*\
   \
   \&#xNAN;***"Program Error: "Instruction #4 Failed - custom program error: 6002 | slippage: Too much SOL required to buy the given amount of tokens"***

**Solution:** If you are willing to accept a higher price difference and would like to catch these trades regardless, increase the Pump.fun slippage %.

If you are uncertain how much should you increase the slippage %, you can follow these steps:
