**💻 Environment**  
Remix Ethereum  
Compile Version: v0.6.12+commit.27d51765

**📝Details**  
After compiling the contract I added liquidity to the 0.5 BNB pancake and I get the error “TRANSFER\_FAILED” when making the purchase.

However, as soon as I added liquidity someone made a purchase in the same second, I don’t know if it was the pancake or some bot. My question is: is there a way to resolve this error?

And if the problem is in the contract, why did someone manage to buy?

Observation: I tried all the slippage.

I cloned a contract similar to Safemoon and decreased the supply to a smaller quantity.

I am willing to pay someone to help me solve this problem.

Hi @brastoken , I have locked this thread because it is dealing with SafeMoon.

Please search the forums first. The solution has already been provided.

Refer to

> [@PSA Regarding SafeMoon Forks on PancakeSwap - Transfers not working? Read This!](https://forum.openzeppelin.com/t/psa-regarding-safemoon-forks-on-pancakeswap-transfers-not-working-read-this/7692):

> Recently PancakeSwap has migrated to V2. You can migrate to V2 following the guide. [https://medium.com/beefyfinance/pancakeswap-migration-2d599e262900](https://medium.com/beefyfinance/pancakeswap-migration-2d599e262900) The V2 router is now [https://bscscan.com/address/0x10ed43c718714eb63d5aa57b78b54704e256024e](https://bscscan.com/address/0x10ed43c718714eb63d5aa57b78b54704e256024e) However if you are already on V1, you will want to stay on V1 if possible because there is a problem with SafeMoon code in that the V1 router for PancakeSwap was hardcoded in. Line 758 [https://bscscan.com/address/0x8076c74c5e3f5852037f31ff0093eeb8c8add…](https://bscscan.com/address/0x8076c74c5e3f5852037f31ff0093eeb8c8add8d3#code)

It’s either SwapAndLiquify needs to be set to False or MaxTxPercent needs to be set to 100.

If you have rejected ownership then you likely cannot get the liquidity back.
