According to Solidus Labs, in the L2 network #Base from the largest American crypto exchange Coinbase, recently launched into public access, scammers have already deployed more than 500 scam tokens, resulting in a trading volume of about $3.7 million, and the profit of the scammers — $2 million, Bloomberg reports.

According to experts, about 300 smart contracts of fraudulent tokens contained hidden functions that allowed their creators to issue an unlimited number of new coins. Another 70 had veiled transaction fee modifiers built into them, and more than 60 completely blocked the possibility of traders selling tokens.
