Scammers stole at least $400,000 using fake Uniswap advertisements on Google, redirecting users to phishing sites that drained their crypto wallets.
Scammers have siphoned at least $400,000 from cryptocurrency users by deploying fake Uniswap advertisements on Google, according to on-chain warnings [1]. The malicious scheme utilized sponsored search results to redirect victims to phishing sites that mimicked the legitimate decentralized exchange, allowing attackers to drain assets from connected wallets [1].

Uniswap is a signatory to a letter urging the Senate to pass the act, specifically emphasizing the importance of Section 604, which provides regulatory certainty for blockchain developers.
Unlike vAMMs, which use virtual accounting entries for pricing, Uniswap v3 utilizes real capital supplied by liquidity providers to back its liquidity curves.
Developers argue that the act is necessary to shield those who do not custody user funds from being classified as money transmitters or facing federal prosecution for building open-source software.
