What is a crypto dusting attack?
Dust has a security reputation problem, mostly because of dusting attacks — a real privacy threat, but one that works very differently from choosing to send away crypto you don't want.
What a dusting attack is
A dusting attack is when someone sends tiny, unsolicited amounts of crypto — dust — to a large number of wallet addresses, not as a gift but as a tracking tool. The goal isn't to give you money; it's to see what you do with it next.
Because blockchains are transparent by design, if you ever combine that dust with other funds in a future transaction, it can help link your separate addresses together — and potentially connect your wallet activity to a real-world identity if any of those addresses have touched an exchange that required identity verification.
Why attackers bother
Linking wallet addresses to a real identity opens the door to more targeted attacks: phishing messages that look convincing because they reference real holdings, extortion attempts, or simply building a profile of high-value wallets to target later. The dust itself isn't dangerous — what you do with it afterward is.
How to protect yourself
The standard advice is simple: don't spend or move dust you didn't ask for. Most modern wallets let you mark small, unrecognized incoming amounts as "do not spend," which keeps them from accidentally being bundled into a future transaction. If you're unsure where an incoming amount came from, leaving it untouched costs you nothing.
Is sending crypto to a site like this one a dusting attack?
No — the direction matters. A dusting attack means someone sends dust to you without asking, specifically to track what you do with it. This site works the opposite way: you're the one choosing to send crypto out to a public address, on your own initiative, because you've decided you don't want the balance anymore. Nobody is tracking your future wallet behavior based on that — the transaction is one-directional and there's nothing further for anyone to observe.
That said, it's still worth applying the same general caution to any crypto tool: only send what you've decided to give away, verify the address and network yourself, and never share your private keys or seed phrase with anyone or any site, ever — including this one.
