How to Fix “Pancake K” Error on PancakeSwap

Are you getting a “Pancake K” error on PancakeSwap?

Here’s the full error message, “The transaction cannot succeed due to error: Pancake: K. This is probably an issue with one of the tokens you are swapping”.

Many users have been encountering this error on PancakeSwap.

It can be scary because you can’t swap the tokens that you’ve bought.

Even if you’ve increased your slippage tolerance, you still might not be able to sell.

In this guide, you’ll learn what does “Pancake K” mean on PancakeSwap and how to fix the error.

What does “Pancake K” mean on PancakeSwap?

Pancake K error PancakeSwap

The “Pancake K” error on PancakeSwap means that your transaction has failed.

In most cases, the error happened because you’re trying to buy or sell tokens at a large price movement.

As a result, the swap will fail because the front end is receiving the wrong information from the smart contract.

Other times, the error is caused by the number of tokens that you’re trying to swap.

For example, if you’re trying to swap SAFEMOON for BNB, you need to enter the number of SAFEMOON that you want to sell.

If you enter a number with all zeroes (e.g. 10000), the transaction might fail.

This is a common issue that many PancakeSwap users face.

Due to the issue, some users will think that the token that they’ve bought is a scam.

However, that’s actually not the case.

The token is only a scam if you’re encountering the “TRANSFER_FROM_FAILED”  error.

How to fix “Pancake K” error on PancakeSwap

To fix the “Pancake K” error on PancakeSwap, you need to change amount of tokens that you’re trying to swap.

Alternatively, you can try increasing your slippage tolerance to 12%.

The “Pancake K” error is usually caused by the number of tokens that you’re trying to swap.

Let’s say that you’re trying to swap 10000 SAFEMOON for BNB.

If you input “10000” SAFEMOON and try swapping it for BNB, you may get the “Pancake K” error.

This is due to the amount of SAFEMOON that you’re trying to swap.

To fix this, you need to change the last number of SAFEMOON.

For example, instead of inputting “10000”, change it to “10001”.

After you’ve changed the last number, your transaction will be successful.

If you’re still getting the “Pancake K” error, you can try increasing your slippage tolerance in increments until the transaction is successful.

Here’s how you can fix “Pancake K” error on PancakeSwap:

1. Choose the tokens that you want to swap

The first step is to choose the tokens that you want to swap.

To begin with, open Trust Wallet and navigate to PancakeSwap via the DApp browser.

If you’re not using Trust Wallet, open the PancakeSwap app.

Once you’re on PancakeSwap, change the token on the “From” field to the one that you’re trying to swap.

Next, tap on “Select a currency” on the “To” field and select BNB/Ethereum depending on the token’s type.

Then, enter the number of tokens that you want to swap for BNB/Ethereum.

For example, if you’re trying to sell 10000 SAFEMOON, enter “10000” on the “From” field.

2. Change the last number to 1

After you’ve entered the number of tokens that you want to swap for BNB/Ethereum, you may get the Pancake: K error.

This is because the number that you’ve entered has too many zeroes.

For example, if you’ve entered “10000”, the transaction will fail.

To fix this, change the last number of the token that you’re trying to sell to “1”.

For example, if you’re selling 10000 SAFEMOON, change the last number to “1”.

The amount of SAFEMOON you’ll be selling is now “10001” instead of “10000”.

Apparently, after you’ve changed the last number to 1, the transaction will succeed.

In other words, you won’t get the Pancake: K error.

However, if you’re still getting the error, try to increase your slippage tolerance.

Start with 5% slippage tolerance, and increase it by 1% each time the transaction fails.

In most cases, setting a 12% slippage tolerance fixes most transaction issues.

You’ve successfully learned how to fix the “Pancake K” error on PancakeSwap!

Conclusion

In most cases, you’ll need to set a high slippage tolerance to swap your tokens.

However, you can bypass this using the trick mentioned in this guide to help you to increase your profits.

In a nutshell, you need to change the last digit of the token that you’re swapping.

For example, if you’re buying 10000 SAFEMOON, change it to 10005 instead.

You’ll then be able to swap your tokens at a 1% slippage tolerance, which will decrease your fee.

If the transaction fails, you can try changing the gas fee to 10 to 30 Gwei.
