If you are familiar with crypto wallets and accounts, you might have heard of sweeper bots. But what are the Sweeper bots and how to defend sweeper bots? This article will help you understand sweeper bots.
What are the sweeper bots?
A sweeping robot is a coded script that can be used on a blockchain address to perform automated outgoing transactions. It works as instructed by the hacker. Like all computer programs, whether a script is malicious depends on who wrote it, what it was designed for, and where it was deployed. After all, being able to programmatically move assets from one address to another can be a very handy feature. However, robot vacuums are often deployed maliciously.
How do Sweeper Bots work?
The public blockchain stores all the data of the network. Such as your balance, incoming or outgoing transactions, swaps, transaction fees, transaction amounts, and the nodes that validate transactions.
If you create a transaction, it remains pending for a period of time due to transaction traffic in the network's transaction pool. Nodes must validate it. When we execute the transaction, all the information can be seen by the nodes. This is how the cleaning The bot finds all the information from the TX pool before your recipient address is received. After that, it measures the transaction amount and takes an average. Explorer's transaction fee calculation. Robot vacuums can move assets in seconds before anyone tries.
How to defend sweeper bots?
First, as a human, you are not faster than code, so our solution will involve code. There are several different solutions here. While there is no guarantee that it will work 100% of the time, there is always one that works for you.
You need to create a list of tokens to save (in priority order) so you can easily plan. This list needs to include the following:
- Token contract address
- Whether the token has been used for staking (is there a time limit for unlocking)
- Are the tokens transferable?
- Token value (prioritized by user judgment or the dollar value)
Most importantly, you must be methodical in order to execute procedures quickly and efficiently. As the saying goes: "Whatever is predetermined, nothing is abandoned."
I hope now you understand what are the Sweeper Bots and how to defend Sweeper Bots. Beating the scavenger is tough, though not impossible. Assuming you have funds in your address (staking, farm, liquidity, NFT) and the hacker somehow didn't notice it or waited for the unlocking process to complete, you must try to save the remaining funds.
