A four-year legal fight ends, and the crypto world is paying close attention to what the ruling means for open-source developers everywhere.
A Manhattan federal judge dismissed a class action lawsuit against Uniswap Labs on Monday, handing the decentralized crypto exchange a clear legal win in a case that pushed the boundaries of platform accountability for fraudulent tokens. Judge Katherine Polk Failla dismissed the case with prejudice, finding that Uniswap bears no responsibility for the actions of unknown third-party token issuers who exploited the platform to run scams on unsuspecting investors.
Uniswap founder Hayden Adams applauded the X verdict, describing it as a “good, sensible outcome” and asserting that it sets a crucial precedent for open-source developers in the future. “If you write open-source smart contract code, and the code is used by scammers, the scammers are liable, not the open-source devs,” he wrote.
A Lawsuit That Refused to Die
Lead plaintiff Nessa Risley filed the original lawsuit in April 2022, targeting Uniswap Labs, founder Hayden Adams, and major venture capital firms Paradigm, Andreessen Horowitz, and Union Square Ventures, claiming they were responsible for losses from scams on the platform. The group claimed the platform turned a blind eye to rug pulls and pump-and-dump schemes, leaving retail investors with very heavy losses. Courts dismissed that first complaint in August 2023, a decision that survived an appeal.

The plaintiffs came back with an amended complaint in May, shifting their legal strategy toward state-level consumer protection violations. The second attempt encountered the same obstacles.
Platform Access Is Not the Same as Fraud
Judge Polk Failla found the plaintiffs fell well short of proving that Uniswap knew about the fraud or played any active role in pulling it off. She drew a stark line between giving someone access to a service and helping them commit a crime—likening Uniswap’s position to a bank processing a money launderer’s deposits without knowledge, or WhatsApp carrying messages between drug dealers without involvement.
“Simply providing the platform on which a fraud takes place is not the same as substantially assisting that fraud,” she wrote. These words may echo through crypto courtrooms for years ahead.
The ruling sets a landmark point for the crypto industry. It could lead to more innovation, as the developers can build innovative projects without fearing lawsuits for actions they did not endorse.
