v4 Hooks: Mostly Unsafe, Pricing Can Trick Settlement
Of 84,000 Uniswap v4 Hooks, after 0x was swept only 19.4% were kept safe—malicious accounts for 54.2%, with a further 26.4% suspected malicious.
The scheme is old-fashioned: they quote a “beautiful” price when you request an estimate, then switch the “blade” at settlement time. What you actually receive can be less by as much as half compared with the quote.
On Base, ETH/NVDAc-related hooks have reportedly siphoned off about $143,000 in total; the batch on the BNB Chain involving USDT/WBNB is about $18,600. Aggregators, wallets, and pre-trade frontends can all be lured into this kind of quote-difference scam.
“Best quote” is only useful when the route is clean. The UI price isn’t the exact cut the chain gives you.
