Are you experiencing a failed transaction on Uniswap?
Are you getting this error, “This transaction will not succeed either due to price movement or fee on transfer. Try increasing your slippage tolerance.”?
Whenever you’re trying to buy a coin by swapping it with another coin, its price tends to fluctuate.
In other words, the price of the coin can change drastically.
For example, when you make a swap, the price movement of the coin might be too large.
If that’s the case, the amount of coins that you’ll get is nowhere near the original amount that you’re supposed to get.
As a result, the transaction will fail due to the large price movement of the coin.
This has to do with your slippage tolerance.
In this guide, you’ll learn how to fix a reverted, rejected, or failed transaction on Uniswap.
How to Fix Transaction Failed on Uniswap
To fix transaction failed on Uniswap, you need to gradually increase your slippage tolerance.
Start by increasing your slippage tolerance to 3%, 6%, then 12%.
You can also increase it by 1% each time to avoid buying the coin at a higher price.
A failed transaction on Uniswap is usually caused by a large price movement of the coin.
Hence, if your slippage tolerance is too low like 0.1%, the transaction will fail if the price movement of the coin is above 0.1%.
Increasing your slippage tolerance will allow the transaction to succeed at a larger price movement.
However, you might buy the coin at a higher price.
Here is how to fix a failed transaction on Uniswap.
1. Increase your slippage to 3%
The first method is to increase your slippage tolerance on Uniswap to 3%.
The default slippage tolerance on Uniswap is 0.1%, which is very low.
This will cause transactions to fail especially if you’re buying a popular coin.
Hence, you can start by increasing it to 1% first.
1% is a suitable tolerance as it isn’t too low or too high.
Here’s how you can increase your slippage tolerance to 3%.
- Go to the Uniswap website and connect your wallet to it.
- Select the token that you want to swap and the token that you want to get.
- Tap on the settings icon to open your transaction settings.
- Increase your slippage tolerance to 3%.
After you’ve increased your slippage tolerance to 3%, try to swap the tokens again.
This time, the transaction should succeed.
If the transaction still fails, you need to further increase your slippage tolerance to 6% or more.
2. Increase your slippage to 6%
If increasing your slippage tolerance to 3% doesn’t work, you need to further increase it to 6%.
This is because the price movement of the coin is larger than 3%.
As a result, the transaction will continue to fail if you don’t increase it.
A 6% slippage tolerance is on the higher-end, so you have to be prepared to buy the coin at a much higher or lower price.
This might cause you to lose profits in the future.
Here’s how you can increase your slippage tolerance to 6%.
- Go to the Uniswap website and connect your wallet to it.
- Select the token that you want to swap and the token that you want to get.
- Tap on the settings icon to open your transaction settings.
- Increase your slippage tolerance to 6%.
After you’ve increased your slippage tolerance to 3%, try to swap the tokens again.
This time, the transaction should succeed.
If the transaction still fails, you need to further increase your slippage tolerance to 12%.
3. Increase your slippage to 12%
The last method is to increase your slippage tolerance to 12%.
If you’re buying a very popular coin, its price will fluctuate a lot.
Hence, your transaction will fail if your slippage tolerance is too low.
By default, the slippage tolerance on Uniswap is 0.1%.
A 12% slippage tolerance is very high, so you have to be willing to buy the coin at a much higher or lower price.
It’s highly recommended that you gradually increase your slippage tolerance by 1% each time the transaction fails.
By doing so, you’ll be able to maximize your future profits.
Here is how you can increase your slippage tolerance to 12%.
- Go to the Uniswap website and connect your wallet to it.
- Select the token that you want to swap and the token that you want to get.
- Tap on the settings icon to open your transaction settings.
- Increase your slippage tolerance to 12%.
After you’ve increased your slippage tolerance to 12%, try swapping the tokens again.
With a 12% slippage tolerance, the transaction is very likely to succeed.
If it doesn’t, you can try increasing the gas price of the transaction.
If all else fails, you can try swapping the tokens a few hours later.
Conclusion
Keep in mind that setting a higher slippage tolerance can result to two things.
Firstly, you might buy the coin at a much higher price.
Secondly, you might buy the coin at a much lower price.
This depends on the price movement of the coin.
Hence, it’s highly recommended that you increase your slippage tolerance bit by bit until the transaction succeeds.
Do not increase your slippage tolerance to 12% right away as you might be buying the coin at a much higher or lower price.
If the transaction continues to fail, you can try swapping the coins a few hours later.
