In the world of Web3, airdrops may seem like a chance to get something for nothing, but hidden traps often cause many users to pay a price. Behind those tokens claimed to be free gifts, there may be carefully designed scams.

First, understand a principle: any interaction on the blockchain is irreversible. When you transfer, sell, or authorize a contract operation with a stranger's token, the risk has already been introduced. Many scam teams use seemingly legitimate airdrop formats to lure users into on-chain interactions, thereby stealing assets or data.

The actual prevention strategies are not complicated. When encountering unfamiliar assets, the safest approach is to avoid them—do not transfer, sell, or authorize. It sounds conservative, but in the field of crypto assets, being conservative often means being safe. Second, be wary of links associated with tokens, as they can easily be disguised as phishing sites. Think for a second before clicking; many risks can be avoided this way.

Besides staying alert, leveraging your wallet's automatic protection features is also crucial. Regularly update your wallet version; many modern wallets have integrated risk token recognition functions that can automatically hide or mark suspicious assets, adding an extra layer of defense for your account.

In summary, think twice before participating in any on-chain activity. There are no free lunches—only risks you haven't seen through.
