Can't remove liquidity nor any transfer function works

Hello, my first post here and it was my first time creating a coin too so I'm ultra new, sorry :flushed:
Basically I forked a coin, it's BSC coin, deployed it and provided liquidity on pancakeswap. Everything went well, I could remove and add liquidity again. I could transfer tokens from my dev wallet until the time I needed to transfer some tokens to my partner so he could provide more liquidity and I accidently sent those tokens to the contract wallet, ok no biggie but everything stopped working after that transaction because when I tried to transfer tokens to my partner again, it failed, not sure if it's a coincidence. You can see my contract here with failed transactions https://bscscan.com/address/0x452c62a9713b269d276b53d81307bc08bc3ea846

It gives me those errors

![](https://bscscan.com/images/svg/shapes/shape-1.svg?v=0.01) Warning! Error encountered during contract execution [ **execution reverted** ]
![](https://bscscan.com/images/svg/shapes/shape-1.svg?v=0.01) BEP-20 Token Transfer Error (Unable to locate corresponding Transfer Event Logs), Check with Sender.

I seriously can't find any answers on google so I came here :flushed:

Hi, welcome! :wave:

Sorry, I am not familiar with the BSC-Chain, maybe you should ask for help in their forum: Home | Binance Chain Forum

It seems like the error message is:
TransferHelper: TRANSFER_FROM_FAILED, but I did not find it.

BTW, you had better format your code to make it easily to read.

Hey guys, I fixed it. For some reason swapandliquify is broken so I set it to false and since then I was able to interact with my token.

Here’s also a thread that I found SafeMoon fork problems with LP

I’m not sure why swapandliquify doesn’t work on mine and his token while all other safemoon forks seem to be working, do you guys know?

how did you set it to false? I cannot change it as well as I have got ownership.

It says: Transaction was not mined within 50 blocks, please make sure your transaction was properly sent. Be aware that it might still be mined!

I have the exact same issue and changing the router to V2 didn’t work either. Not sure how to debug it.

So I am having this issue! Made a coin put 0.8 BNB into liqu and now its stuck! Just won’t do shit! I want to know how to change the code! So I put Swapandliquify to false and now what? Do I have to upload it to BSC Scan? How do I make the new code the active code? That is the part I am most confused by

Hoping to hear back from you soon!
You can reach my Telegram if that is easier @Jagg753

Did you fix it man? I lost 0.8 right ow

Did u fix it at all? I have lost 0.8 to this right now! I don’t know what to do! I tried swapping it for WBNB but didn’t do anything! Not sure where to go… Not even getting an error. I am so sad rn :frowning:

The contract’s code is immutable but if you still have ownership and can turn off swap/liquify by setting the associated flag to false then you should be able to withdraw just fine. There are many other things that may go wrong though, like max transfers. I didn’t look as to why this happens but sometimes I have to ask PancakeSwap to give me wBNB rather than BNB.

If you send me your contract I’d be happy to look at what is going wrong (if you still didn’t manage to get the liquidity out).

Hi Peire - hope all is well. I would appreciate it immensely if you can please review our code for why we can’t withdraw our liquidity (it doesn’t work when I use BNB or WBNB, thanks). Thank you. https://bscscan.com/token/0x5489e40f640f6437fb32afa2b92b362cafe4bde3#balances

Hi Perie_Cardenal, I recently set swapandliquify to true and when I tested a transaction after this, all of my liquidity 1.93 BNB from pancakeswap was transferred to my contract address. Is there a way to get this back? Here is the transaction where it occurred https://bscscan.com/tx/0xb56cb68ea096906d4281912f986ea68a72c0a0b8a56e0ce67c0b0ea2c2cc5ffc

Here is my contract address: https://bscscan.com/address/0xdba9b1d91e710b4ac9a1df3a7b3f632f4297f0a3
Any assistance is greatly appreciated, thank you

Were you able to figure this out? I am having a similar issue, all my BNB was transferred to the contact address after enabling swapandliquify

Could be your max tx amount that's at 2% (I see you removed liquidity so you figured it out)

Seems like you figured it out also :slight_smile: Feel free to share the reason here so in the future people can avoid this issue. I don't get notifications when people reply to me here so I didn't see it earlier.

please help. I use safemoon fork for smart contract, but i cant remove Liquidity on PancakeSwap. This is the smart contract

Hi guys, I can't remove Can you help me to explain why I can't remove the liquidity pool? (I have fork the Smart Contract from FoeverFOMO token) Thank you so much.

Hi Peire,

I am also having the issue when trying to withdraw my liquidity from Pancakeswap. Here is my contract

and the error was estimategas failed. I have attached a screenshot of the issues.


I appreciate any help that you can provide.

Best,
KR

I also had a similar issue for a few month, but was able to finally remove 32 bnbs the other day.

Try removing BNB's step by stem. If somebody has the same issue, feel free to contact me so I may try to help. It tookme 4 months to get my liquidity back lol

I've been through the same problem.

After that I recovered 15 BNB from two contracts. I'm a developer of two big projects (doxxed) and recognized in the DeFi community.

Write me if you need help:
