According to Odaily Planet Daily, Uniswap founder Hayden Adams reminded: "Please do not submit any vulnerability reports through unofficial portals (we are not associated with such platforms). All bug bounty applications can be sent through the official portal (uniswap.org/bug-bounty)." The OpenBounty (@ShentuChain) platform lists bug bounty programs for multiple projects, including Uniswap, Ethereum, Arbitrum, etc.
