Issues on the Exchange

INSUFFICIENT_OUTPUT_AMOUNT

The transaction cannot succeed due to error: PancakeRouter: INSUFFICIENT_OUTPUT_AMOUNT. This is probably an upshot with one of the tokens y'all are swapping.

the transaction cannot succeed due to error: execution reverted: pancakerouter: insufficient_output_amount.

You're trying to swap tokens, simply your slippage tolerance is too low or liquidity is too low.

1 .

Refresh your page and try over again later.
2 .

Try trading a smaller amount at one time.
3 .
Increase your slippage tolerance:
1. 1 .
  
  Tap the settings icon on the liquidity page.
2. 2 .
  
  Increase your slippage tolerance a little and effort again.
four .

Lastly, try inputting an amount with fewer decimal places.

This usually happens when trading tokens with depression liquidity.

That means there isn't enough of one of the tokens you're trying to bandy in the Liquidity Pool: it's probably a small-cap token that few people are trading.

All the same, there's too the chance that you're trying to trade a scam token which cannot exist sold. In this case, PancakeSwap isn't able to block a token or return funds.

INSUFFICIENT_A_AMOUNT or INSUFFICIENT_B_AMOUNT

Neglect with error 'PancakeRouter: INSUFFICIENT_A_AMOUNT' or Fail with error 'PancakeRouter: INSUFFICIENT_B_AMOUNT'

You're trying to add/remove liquidity from a liquidity puddle (LP), just there isn't enough of one of the two tokens in the pair.

Refresh your page and try again, or endeavor over again afterwards.

ane .

Tap the settings icon on the liquidity folio.
ii .

Increase your slippage tolerance a little and try again.

The error is caused by trying to add together or remove liquidity for a liquidity pool (LP) with an bereft corporeality of token A or token B (ane of the tokens in the pair).

It might be the example that prices are updating too fast when and your slippage tolerance is besides depression.

OK, so y'all're really determined to fix this. We really don't recommend doing this unless you know what y'all're doing.

There currently isn't a simple way to solve this issue from the PancakeSwap website: you'll need to interact with the contract directly. You lot can add together liquidity directly via the Router contract, while setting amountAMin to a modest amount, then withdrawing all liquidity.

Corroborate the LP contract

i .

Select Write Contract , and then Connect to Web3 and connect your wallet.
2 .
In department "1. approve", corroborate the LP token for the router past entering
1. i .
  
  spender (address): enter the contract address of the LP token you're trying to interact with

Query "balanceOf"

two .

In 5. balanceOf , input your wallet accost and hit Query .
3 .

Keep track of the number that's exported. It shows your residuum within the LP in the uint256 format, which you lot'll need in the next pace.

Add or Remove Liquidity

one .

Select Write Contract and Connect to Web3 as above.
2 .

Detect addLiquidity or removeLiquidity (whichever i you lot're trying to practise)
3 .

Enter the token addresses of both of the tokens in the LP.
4 .

In liquidity (uint256), enter the uint256 number which you got from "balanceOf" above.
v .

Prepare a depression amountAMin or amountBMin : try one for both.
6 .

Add together your wallet address in to (address) .
vii .

Borderline must be an epoch time greater than the fourth dimension the tx is executed.

This can cause very high slippage, and can cause the user to lose some funds if frontrun

PancakeRouter: EXPIRED

The transaction cannot succeed due to error: PancakeRouter: EXPIRED. This is probably an consequence with one of the tokens you are swapping.

Try over again, but confirm (sign and broadcast) the transaction every bit shortly as you lot generate information technology.

This happened considering yous started making a transaction, but yous didn't sign and broadcast it until it was past the deadline. That means yous didn't striking "Confirm" quickly plenty.

Pancake: K

The transaction cannot succeed due to error: Pancake: One thousand. This is probably an upshot with one of the tokens you are swapping.

Effort modifying the amount on "To" field. Therefore putting "(estimated)" symbol on "From". Then initiate the swap immediately.

This unremarkably happen when you are trying to bandy a token with its own fee.

Pancake: TRANSFER_FAILED

The transaction cannot succeed due to error: execution reverted: Pancake: TRANSFER_FAILED.

Make certain yous have 30% more tokens in your wallet than yous intend to trade, or endeavour to trade a lower amount. If you want to sell the maximum possible, try lxx% or 69% instead of 100%. Caused past the pattern of Restorative Rebase tokens similar tDoge or tBTC. Sympathise how restorative rebase tokens piece of work .

Some other possible cause of this event is the malicious token issuer only suspended the trading for their token. Or they made selling activeness only possible for selected wallet addresses. Please always practice your own research to avert any potential fraud. If the token you are trying to swap only failed with this error code is coming from an airdrop, that is most likely a scam. Delight exercise not perform any token approval or follow any links, your fund may exist at gamble if you endeavor to practice so.

Transaction cannot succeed

Try trading a smaller amount, or increase slippage tolerance via the settings icon and try again. This is caused past low liquidity.

Cost Bear upon too High

This transaction would neglect. Please contact support

If y'all got this error while removing liquidity from a BNB pair:

Please select "Receive WBNB" and retry.

If you got this error while trying to bandy:

Please contact the projection team of the token you're trying to swap. **** This issue must be resolved past the project team.

This outcome (while swapping) is caused by tokens which have hard-coded the V1 PancakeSwap router into their contract.

While this practise is ill-advised at best, the reason for these projects having washed this appears to be due to their tokenomics, in which each purchase sends a % of the token to LPs.

The projects affected will probable non work with the V2 router: they will almost likely need to create new versions of their tokens pointing to our new router address, and migrate any existing token holders to their new token.

We recommend that whatever projects which created such tokens should also make efforts to prevent their users from adding them to V2 LP.

Cannot read property 'toHexString' of undefined

"Unknown mistake: "Cannot read property 'toHexString' of undefined"

When trying to swap tokens, the transaction fails and this error message is displayed. This error has been reported on mobile devices using Trust Wallet.

Issues with Syrup Pools

BEP20: burn down amount exceeds balance

Fail with mistake 'BEP20: burn amount exceeds balance'

You don't have enough SYRUP in your wallet to unstake from the CAKE-Cake pool.

Get at least as much SYRUP as the amount of Cake that yous're trying to unstake.

1 .

Buy SYRUP on the exchange. If you want to unstake 100 Block, you lot demand at least 100 SYRUP.

To cease this happening once more, don't sell your SYRUP. Y'all yet demand it to unstake from the "Stake CAKE Earn CAKE" pool.

This error has happened because you have sold or transferred SYRUP tokens. SYRUP is minted in a i:1 ratio to Block when you stake in the Block-Cake Syrup Puddle. SYRUP must be burned at a 1:1 ratio to Cake when calling leaveStaking (unstaking your CAKE from the pool), so if you don't take enough, you can't unstake from the puddle.

Out of Gas error

Alert! Mistake encountered during contract execution [out of gas]

You have set a low gas limit when trying to make a transaction.

Basically, your wallet (Metamask, Trust Wallet, etc.) can't stop what it's trying to do.

Your wallet estimates that the gas limit is too low, and then the part call runs out of gas before the role call is finished.

BEP20: transfer amount exceeds allowance

Fail with fault 'BEP20: transfer amount exceeds assart'

1 .

Use Unrekt.net to revoke approval for the smart contract you lot're trying to interact with
ii .

Approve the contract again, without setting a limit on spend allowance
3 .

Try interacting with the contract once again.

This happens when y'all set a limit on your spend allowance when you starting time approved the contract, then try to bandy more than than the limit.

BEP20: transfer amount exceeds residual

Neglect with error 'BEP20: transfer amount exceeds residual'

Y'all're probably trying to unstake from a Syrup Puddle with low rewards in it. Solution below.

If non, you may be trying to send tokens that you don't have in your wallet (for example, trying to send a token that is already assigned to a pending transaction). In this case, but make certain you have the tokens yous're trying to use.

Firstly, let the team know which puddle you're trying to unstake from, so they can pinnacle upward the rewards. If you're in a bustle to unstake and you don't listen losing your pending yield, try an emergencyWithdraw:

You lot can perform an "emergencyWithdraw" from the contract directly to unstake your staked tokens.

1 .

Find the contract address of the Syrup Pool you're trying to unstake from. You can find it in your wallet's transaction log.
4 .

Click "Connect to Web3" and connect your wallet.
5 .

In section "three. emergencyWithdraw", and click "Write".

This volition unstake your staked tokens and lose any uncollected yield.

This will lose any yield that you haven't harvested notwithstanding.

This mistake tends to appear when you're trying to unstake from an old Syrup Pool, only there aren't enough rewards in the puddle left for y'all to harvest when withdrawing. This causes the transaction to neglect.
