Airdropped NFT or token scams#

Last modified: August 10, 2026

An airdrop is a token or NFT sent to a wallet without a direct purchase by the recipient. Airdropped-token scams use that unexpected item as bait so you visit a fake claim site, sign a wallet request, or approve a malicious contract.

On Centurion, airdropped items may be CRC-20 tokens, CRC-721 NFTs, or CRC-1155 NFTs. Receiving one does not mean Centurion Labs sent it, reviewed it, or endorsed it.

What it looks like#

You open your wallet and see an unknown NFT named like a reward, refund, or limited-time claim. The description tells you to visit a claim page. The page says you can redeem the NFT for CTN, but your wallet prompt asks for permission to let an unknown contract move your tokens. If you approve it, the attacker can drain assets later even though the original airdrop looked harmless.

How the scam works#

Attackers may:

Send many wallets the same token or NFT so it appears in transaction history.
Put claim instructions, reward language, or a lookalike brand name in the token metadata.
Direct users to a fake claim or migration site.
Ask for an unlimited CRC-20 allowance or NFT operator approval.
Hide a malicious approval inside a batch of wallet actions.
Use a token warning or spam label delay to reach users before scanners have enough data.

Checks before interacting#

Treat unexpected tokens and NFTs as unsafe until verified.
Do not follow claim instructions written in token names, descriptions, or images.
Verify any real campaign through official Centurion sources you reach independently.
Read the wallet request. Cancel if it asks for an approval, operator permission, or transfer you did not expect.
Remember that moving, swapping, hiding, or revoking permissions can incur a Centurion network cost measured in Newtons and paid in CTN.

If you already interacted#

Stop using the claim site. Review CRC-20 allowances, CRC-721 and CRC-1155 operator approvals, and smart-account permissions. Revoke suspicious permissions through a trusted Centurion-compatible tool. If you shared a recovery phrase or private key, create a new wallet on a clean device and move remaining assets.

Stay safe#

Do not try to claim, swap, or sell an unexpected airdrop just to see what happens. A spam warning is useful information, but no warning system catches every new or obscure scam immediately.
