How to Fix “Cannot Estimate Gas” Pancakeswap Error
Decentralized exchanges connect with coins and tokens that can’t be found elsewhere.
If you are trying to swap, for example, BNB for SafeMoon on PancakeSwap, but the operation didn’t go as planned, you are not alone.
Many users have encountered a pop-up error message that says: “The transaction cannot succeed due to error: cannot estimate gas. Transactions may fail or may require manual gas limit. This is probably an issue with one of the tokens you are swapping”.
This error is happening to a high number of users that try to trade tokens, but the platforms’ features are just not working as they should.
Errors like this can happen, so we have performed our own research in order to resolve this issue once and for all.

What Does the Error “Cannot Estimate Gas” Mean?
The “Cannot Estimate Gas” error basically means that the platform can’t estimate the fees associated with a transaction.
Since the gas fee can’t be estimated, the platform refuses to process the trading operation.
Nonetheless, there are other reasons that can lead to this message appearing when trying to sell or buy a token.
You might be trying to purchase a scam token.
In that case, gas fees won’t be generated, which will prevent you from selling or paying for it.
We highly recommend checking the recent transactions as a token before you decide to pay its price.

“Transaction May Require Manual Gas Limit on PancakeSwap”
Gas fees must be paid when you are trying to swap tokens on PancakeSwap in order to validate the transaction.
If the “transaction cannot succeed due to error on the estimated fee,” then you might have to manually set the token limit on the exchange.
Paying higher fees might solve the gas error, but of course, trading and selling come at a transaction cost that might be too elevated for your pocket.
But worry not - maybe you won’t have to pay for anything and can fix the gas error by trying out one of the following fixes we are about to show you.
Note: You can get more insights about the error “Cannot Estimate Gas” by checking out the official PancakeSwap Swapping Guide.
Just make sure to understand each fee that appears when you sell or trade a token before placing a transaction. Also, scam tokens are real - don’t sleep on them!
How to Fix “Cannot Estimate Gas” PancakeSwap Error Message
Luckily, finding a fix for PancakeSwap errors is often pretty straightforward.
We have already covered other errors in our articles, such as for example, the PancakeSwap: No Provider Was Found fail.
If you carefully read the following steps, you will find a solution for the previously mentioned fail in no time!
1. Increase Gas Limit on PancakeSwap
The first solution consists of increasing the gas limit of your swap.
Transaction speeds are ruled by GWEI.
As a consequence, if you allow the platform to perform faster transactions, you will be charged more.
- Go to Settings on PancakeSwap. This can be done from the “Swap” menu;
- In Global Settings, change transaction speeds to “Fast” or “Instant;”
- Try to perform the trade or swap again. Naturally, you will experience a price impact on the operation because the manual gas limit has been increased.
If, for example, you don’t want to swap a token at higher fees, then try the following fix instead.
2. Modify the Amount You Want to Trade
Let’s say that you want to trade a token, but the number you input is 3123.89375.
As weird as it might sound, having too many decimal places might end up messing up with the estimated fee.
Therefore, we need to get rid of these too many decimal places, so the pop-up error disappears.
Change the Last Numbers to a Smaller Amount
Since the exchange might be encountering problems with the specific number of tokens you are trying to trade, then do the following:
- If you want to trade 3123.89375 tokens, change it to 3123.123;
- If this doesn’t work, simply input 3123.000 - get rid of all the decimals.
The “From” field must be estimated by the exchange so the trade can succeed.
Nonetheless, this doesn’t always work.
Some users have stated that they have input numbers without decimals and still can’t trade the token.
3. Increase Slippage Tolerance to 12%
The slippage tolerance sets the ratio between the expected price and the price in which the trade will execute.
Changing the slippage tolerance is not a child’s play.
You must perform your own investigation before deciding to alter the slippage tolerance set by the platform.
Tap on the Settings Icon and Change Slippage Tolerance to 12%
Our research has proven that this is the most efficient method for getting rid of this error message.
In order to change the slippage tolerance, do the following:
- Go to “Swap” on PancakeSwap and open “Settings;”
- There, manually write “12%” to change the slippage tolerance;
- Confirm your decision and try to sell or swap the token again.
Consider that this might dramatically change the final outcome of the operation.
In any case, the swapping must take place without errors this time.
In conclusion, you must allow the exchange to estimate the transaction in a way that it can take place without errors.
