Uniswap Labs and its founder, Hayden Adams, have secured a significant legal victory. A US federal judge dismissed a four-year-old class-action complaint that sought to hold the decentralized exchange accountable for alleged rug pull and pump-and-dump fraud on its platform.

Judge Katherine Polk Failla ruled that Uniswap cannot be held responsible for the actions of anonymous token issuers. Operating as a decentralized platform with an open-source trading environment does not constitute assisting fraud, the court determined. This decision upholds legal safeguards for open-source DeFi platforms.

The ruling follows an earlier win for Uniswap in February, where a patent infringement lawsuit filed by Bancor-affiliated entities was dismissed by a New York federal judge.
