Hi is it possible to somehow snipe specific projects instead of every project out there?

[tuxforensics]

Of course, you will have to add conditional statements that compare the new token address with the token you are looking for.

I've found some errors in the code, you forgot the '' in all console.log but I have a problem with one of your const const privateKey = ''; Should this not be the mnemonic phrase ?

[ozgurk78]

yess this must be privatekey, also orginal is mnemonic phrase const privateKey = '';

[condor-webdev]

yess this must be privatekey, also orginal is mnemonic phrase const privateKey = '';

Yes finally it's what I've done but still getting an error, the same in that one and the original one. It comes from Ankr url. Any good advice what to use for the websocket ?

Finally I tried it already but unfortunately the don't have the testnet. Any idea where to look ?

Guys: Ankr is perfectly working. WHen you create the API endpoint, it is asking you either to have a classic or tokenized authentication. Choose tokenized, and you will have no problem with yous ANkr wss endpoint...

Ankr isn't returning the proper cost from pancake but quicknode just works.

I already fixed it. Thanks. But when I use gas limit can I use always 500,000 or more? Because some of my transactions are with 250-300,000 gas used... or is there a way how to set optimal gas limit for all transactions? Thanks!

gas limit is the maximum gas you ready to pay. It's not mean that every transaction takes 500.000. btw, can you send me the script buying tokens? My email: datlilkayz11@gmail.com Thanks

[vlbhtcno1]

Following your code, I got the issue UnhandledPromiseRejectionWarning: Error: insufficient funds for intrinsic transaction cost maybe the issue come from the gasPrice and gasLimit as well

[Tomix3D]

And is there a way how to predict gas used for tx?

My code is here btw: https://github.com/ethers-io/ethers.js/issues/1635

The optimal setting would be 400.000 and 6 wei.

Could you please share the script for selling? I am able to buy, but not to sell

Thanks in advance!

Maybe you need 2 changes.

1. Change the approved address from WBNB to your token which you want to sell
2. Change the index of token in swapExactTokensForTokens. For buying a token, the index is [WBNB, token address], for selling maybe it's [tokenaddress,WBNB].

I'm not sure that my solution will work or not. But from the view of a developer, I think it work.

I will try that. But my major concern is that not all tokens have the same amount of decimals. WBNB has 18, safemoon for example has 9 decimals. Slippage would be 12% or more in this case but my script does not work.

Don't have any way to set specific slippage for specific token like SafeMoon. decimal value and slippage must be added manually.

[Tomix3D]

Hey, sorry I can't.. but my swap code is above.

[MatthiasT91]

Anyone else knows why I'm getting this in the console? "this should not happen" It's getting stuck after getting approved and I get to see the hash and the transaction comes through but never buys the token. and at the end states that message. "this should not happen". It's not written anywhere in my code. Thanks.

// Approves the transaction and then gives out a receipt check bscscan.com console.log('After Approve'); const receipt = await tx.wait(); -- Get's stuck here? console.log('Transaction receipt'); console.log(receipt); }

[HugoMag]

Hi, Can anyone help me on the following? When I run this code I always get the error "insufficient funds for gas * price + value". My wallet has 0.2 WBNB and if I tried to do the swap in my Metamask wallet it works so I'm not sure what I'm doing wrong.

Thanks!

[SerMojo]

Same problem as Matthias. I've got this message "this should not happen" when calling Approve or swapExactTokensForTokens. I'm pretty sure all my parameters are ok and in the right unit (using 6e9 for gasPrice and 30000 for GasLimit). I just don't get it and it's driving me nuts. If someone has an idea or can help me on that, thanks in advance!
