Fake tokens are increasingly prevalent on decentralized exchanges (DEXs), often appearing legitimate due to early trading activity. Despite being live, liquid, and actively traded, these tokens can conceal contract logic that makes selling, transferring, or exiting unsafe. Risks include transfer restrictions, honeypot mechanics, retained control, and abnormal approval or liquidity behavior, which may only become apparent after transactions are executed. Tools like @web3_antivirus are emerging to help users identify these risks before interacting with potentially fraudulent tokens, aiming to protect traders from hidden dangers in the decentralized finance ecosystem.
