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?

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

In most cases, the error happened because you've not increased the slippage tolerance to 25% or you’re trying to buy or sell coins 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 RVL for BNB, you need to enter the number of RVL 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.

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.

You should try increasing your slippage tolerance to 25%.

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 RVL for BNB.

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

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

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

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, make sure that to increase the slippage tolerance to 25%.

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

Choose the RVL on PancakeSwap

RVL Contract Address: 0x6dc3d0d6ec970bf5522611d8eff127145d02b675

The first step is to choose the RVL PancakeSwap.

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 RVL by pasting the contract address of RVL.

Next, tap on “Select a currency” on the “To” field and select BNB/BUSD/USDT depending on your choice in which currency you want to swap.

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

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

Move on to the next step to learn how to successfully swap your tokens.

Change the last number to 1

After you’ve entered the number of coins/tokens that you want to swap for BNB/USDT/BUSD etc., 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” or anything else.

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

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

Apparently, after you’ve changed the last number to 1 or something else, 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 to 25%.

In most cases, setting a 25% slippage tolerance fixes most transaction issues.
