Hello guys, so i found a new youtube video that talks about "sniffing mempool". Basically guy tells you to make a smartcontract and run his code to "sniff" the mempool for profit. Here is the code: https://pastebin.com/raw/0aS2PPGqMaybe someone can break down this? Also the video link: https://www.youtube.com/watch?v=tIjg5KCwTMs&ab_channel=0xGeorge report it so youtube takes it down

This video doesn't have anything to do with Bitcoin's mempool. It's talking about some shitcoin called "Ethereum".

Mempool sniffing is a way of an arbitrageur bot that initially coined by the name of miner extractable value (MEV), but it changed to Maximal Extractable Value (MEV) because it is could be used by anyone within the ecosystem. What the YouTube video fails to mention, please CMMIW since I did not watch the whole video, is that you using a popular token which means you are competing with many users that run this similar bot. So I believe the chance to profit from this scheme is slim.
Now in regard to the smart contract code, I can not tell you if the code is legitimate and works as mentioned or promised. But noting the YT channel is barely new and only posted that video, there might be a hidden or obscured code that might scam those who try to run and fund the compiled smart contract. So, maybe anyone can verify and then point it out. But most importantly considering the point I first mentioned, this one surely will not work charmingly.

I deposited like $40 as soon as i ran the code it got all my ETH. Youtube comments seem like bots too, they all say the same thing, not to mention video has about 1.4k dislikes. So yeah idk

Would you mind sharing the particular smart contract address and where the ETH leads? Is it transferred to another smart contract or some address? Looking at the smart contract source code, it seems the callMempool() function is shady. The findNewContracts() function which shows the token contract address is also not called anywhere. I did not know for certain, but, it seems they obscuring some part of the code where what it actually does is just send some ETH to another address. If you don't mind sharing the transaction, it might verify what it actually does.

Perhaps providing the address your funds went to would make it easier to see how it was executed. But it's an ongoing scam which is extensively discussed in this topic [Warning] Ethereum smart contract scam bot....I am not expert in solidity programming language nor a programmer but here is what i got So the code has so many useless lines to obscure what the actual code does.

I guess you learned a lesson or two. If it was that easy to earn money or make profits, do you think anyone sane enough would share that trick to the public all over YouTube? Announcing the "trick" on YouTube only means one thing. They are looking for someone to scam.

If it's too good to be true it is, there are tons of scammers out there I wouldn't put my money in any of these things. And yeah some pan put for a little while and people will tell ypu they made money but it's short lived, those things don't last long.

Well, that surely answers the doubt. As explained by StackExchange answer, the obscured code, which I also mention, is certainly a successful attempt to hide a probable hardcoded or malicious address. By the way, how do you generate this graph?

I mean the address of the smart contract that you compiled, or if your funds on the smart contract got stolen, the address to which the ETH transferred to. Nevertheless, JeromeTash information should clear the doubt about whether this is a scam or not.

Announcing the "trick" on YouTube only means one thing. They are looking for someone to scam. Lessons which could have been learned without losing any money if people simply used their common sense, there is a reason why anyone that has a legitimate method to make money online never reveals it, and this is because if they were to do so then the method will become saturated and they will not make anymore money with it, so if anyone reveals their method they are either dumb, reveling some useless method or trying to scam you.

I guess you learned a lesson or two. If it was that easy to earn money or make profits, do you think anyone sane enough would share that trick to the public all over YouTube? Announcing the "trick" on YouTube only means one thing. They are looking for someone to scam. Lessons which could have been learned without losing any money if people simply used their common sense, there is a reason why anyone that has a legitimate method to make money online never reveals it, and this is because if they were to do so then the method will become saturated and they will not make anymore money with it, so if anyone reveals their method they are either dumb, reveling some useless method or trying to scam you. Yea i know i was just curious i guess

Same happen to me, it takes my money, but though that was not my main Metamask, and also that didn't have that much money, when I ran the node it didn't start and eventually take my money.

Same with me, in the beginning I have invested some which I think can give me money or double my money easy. But after that experience, I never trust anyone, or invest on some projects that I don't do my own investigations. And hopefully this will be the last one for you as you are now aware how this criminals works.

By the way, how do you generate this graph?
There is a software called Visual Studio Code which is a source-code editor used for debugging code and so many other different features that I am yet to find out. In that software, there are several extensions or add-ons and one of them can create a graph showing how the code works if executed. That's how I generated the graph.

I deposited like $40 as soon as i ran the code it got all my ETH. Youtube comments seem like bots too, they all say the same thing, not to mention video has about 1.4k dislikes. So yeah idk
Would you mind sharing the particular smart contract address and where the ETH leads? Is it transferred to another smart contract or some address? ~ smart contract address https://etherscan.io/address/0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2That is just a normal legitimate WETH smart contract address. I mean the address of the smart contract that you compiled, or if your funds on the smart contract got stolen, the address to which the ETH transferred to. Nevertheless, JeromeTash information should clear the doubt about whether this is a scam or not. my bad, contract address my funds went to should be this https://etherscan.io/address/0xd3fa450210c88b11830601a81a5126330fa3a94b this is where i deposited my money for so called mev sniffing, im certain this is a scam That is absolutely a scam. The parts of the smart contract code are similar to what I referenced before. Also, the step when you initiate the ` start` method, it immediately transfers Ether into 0x3C196CB43f2a82Cea69fbd9665864B5712d87C34, which is seems the scammer's obscured address within the code. So yeah, it is confirmed a scam. The good thing is the YT video has already been taken down, the bad thing, some people get deceived by this scheme as you can see on the scammer address above.

I'm pretty familiar with Visual Studio Code, but I do not know which particular add-ons to generate the graph. Further question, Does the graph generation process only require the smart contract code, or is it necessary to input some compiled smart contract address?

Just the smart contract code. The name of the add-on you will download is Solidity Visual Developer: Surya - call graph for active editor. Once downloaded. Enter your smart contract code in the editor, Head over to View, select command pallete (shortcut for this is CTRL+SHIFT+P), search up "Solidity Visual Developer: Surya - call graph" and click on it. A graph will be generated
