A wallet list is not a list of trusted senders
Public addresses can receive unsolicited assets. A token name that claims a prize, a support alert or an expiring reward is information supplied by its creator, not an authenticated message from the wallet provider.
Do not infer value from a displayed price. The scam can rely on getting you to visit a redemption page even when the unexpected item itself is worthless.
The costly step can involve a different collection
Imagine an unsolicited NFT whose image says “claim your reward.” The linked page requests operator approval over a collection you already own. That approval concerns the valuable collection, even though the page introduced itself through the unrelated airdrop.
Read which contract and operator a request affects. The fact that the initial item arrived for free does not make the follow-up authorization harmless.
Ignoring the bait can be enough
If you have only received the asset, avoid its links and use supported hide or spam-report controls where available. You do not need to send it to a special cleanup address to regain control of your wallet.
If you already approved or signed something, inspect that specific authorization and affected assets. Merely hiding the original airdrop does not revoke permissions granted to another contract.
Direct answers
Questions people ask
Does an unexpected NFT prove my wallet was hacked?
No. Passive receipt is possible at a public address. Investigate outgoing transactions and authorizations separately from the unsolicited item’s presence.
Should I visit its website to remove it?
An unsolicited asset’s website is not a trusted cleanup service. Use the wallet’s own display controls and independently verified permission tools when relevant.
Inspect the evidence
The answer and key facts have stable claim links. These records retain the scope and qualification when reused.
An unknown token or NFT can be sent to your public address without your consent. Its appearance is not evidence that someone knows your private key or that a reward is legitimate. The danger often begins when its name, image or website persuades you to reveal secrets, sign an authorization or approve access to valuable assets.
