Uniswap V4

Uniswap V4 receives a B- risk grade (30/100) from Hindenrank, where lower scores indicate lower risk. Uniswap V4 introduces powerful but risky innovation with its hook system. While the core Uniswap team and protocol are well-funded and battle-tested, the permissionless hook ecosystem creates an entirely new attack surface that has already been exploited twice. The singleton architecture trades gas savings for systemic concentration risk. The UNI fee switch (live July 2026) significantly improves the value accrual story — actual burn revenue changes the token economics. Best suited for DeFi-savvy users who carefully evaluate the hooks on pools they interact with. Uniswap V4 is the latest version of the world's largest decentralized exchange. Its headline feature is 'hooks' — customizable plugins that developers can attach to trading pools to add features like dynamic fees, limit orders, and custom trading strategies. V4 also consolidates all pools into a single smart contract (reducing costs by up to 99% for pool creation) and supports native ETH trading. With $836M in TVL and the UNI fee switch now live — burning protocol revenue — V4 is generating real cash flows for token holders for the first time.

The key risks identified for Uniswap V4 are: (1) Hooks can run any code when you trade — a malicious or buggy hook could steal your funds or give you a worse trade (2) All V4 pools share one smart contract, so a single vulnerability could put everyone's funds at risk at the same time (3) Two hook exploits have already occurred ($11M Cork Protocol, $8.4M Bunni V2), showing the hook ecosystem is a recurring source of losses
