Uniswap Labs announced that it will launch a $15.5 million bug bounty program for the v4 core contracts, incentivizing responsible vulnerability disclosures. All reports must be submitted directly to the v4 Bug Bounty page on Cantina within 24 hours of discovery. Uniswap v4 is the latest iteration of the Uniswap protocol, introducing new 'hooks' functionality that allows developers to customize pools, trades, fees, and liquidity provider (LP) position interactions. This version aims to significantly reduce user costs, lowering pool creation fees by 99.99% and optimizing the costs of multi-hop trades.
