Are you facing a failed transaction on Uniswap with errors like "This transaction will not succeed due to price movement or fee on transfer"? This guide explains why transactions fail and how to resolve them by adjusting your slippage tolerance.
Why Do Uniswap Transactions Fail?
When swapping tokens on Uniswap, price fluctuations can cause transactions to revert. Here’s why:
- Price Volatility: Token prices can shift dramatically between transaction initiation and execution.
- Low Slippage Tolerance: If the price change exceeds your set slippage tolerance (e.g., 0.1%), the transaction fails to protect you from unfavorable swaps.

How to Fix Failed Transactions
1. Gradually Increase Slippage Tolerance
Start with small increments to avoid overpaying:
3% Slippage: Suitable for mild volatility.
- Navigate to Uniswap → Settings → Adjust slippage to 3%.
6% Slippage: For moderate price swings.
- Update slippage to 6% if 3% fails.
12% Slippage: For highly volatile tokens.
- Use sparingly, as it may lead to significant price differences.
2. Adjust Gas Fees
High network congestion? Increase gas fees via your wallet settings to prioritize the transaction.
3. Retry Later
If adjustments fail, wait a few hours for market stability before retrying.
Key Considerations
- Avoid Extreme Slippage: Jumping directly to 12% may result in poor swap rates.
- Monitor Token Trends: Check price charts before swapping to anticipate volatility.
