What’s a sweeper bot?

A sweeper bot is a piece of coding script that can be used on a blockchain address to perform automatic outgoing transactions. It works following the instructions that the hacker has instructed


Does it work on any public address?
No, A hacker can set a sweeper bot only if the hacker has access to the wallet seed phrase or private key. A Hacker can set a sweeper bot in all the addresses your private key or seed phrase contains.

It can be on any different EVM ( Ethereum virtual machine ) based blockchains, irrespective of Layer 1 or Layer 2 chain.

How Does It Work?

You might be wondering, How does the bot move assets so fast and calculate fees to execute a transaction?

A public blockchain stores all the data of a network. Like Your balance, Incoming or outgoing transactions, swaps, transaction fees, amount of the transaction, and nodes that validate transactions.

If you create a transaction, it remains pending for some time due to transaction traffic in the transaction pool of a network. Nodes must validate it.

When we execute a transaction, all information can be seen by the nodes. That’s how a sweeper bot could find all the information from the TX pool even before your recipient address receives it. After that, It measures the transaction amount and takes an avg. Transaction fees calculation from explorers. Sweeper bot can move assets in seconds before any human can even try.
