A U.S. federal judge has dismissed the class-action lawsuit against Uniswap Labs and founder Hayden Adams, ruling that the plaintiffs failed to prove that the platform should be held responsible for trading losses. This ruling ends a years-long case and clarifies that developers of decentralized trading platforms are not liable for fraudulent activities, thereby tightening the legal liability boundaries for DeFi platforms.

ChainCatcher News: A U.S. federal judge has dismissed the remaining state law claims against Uniswap Labs and its founder Hayden Adams, ending a years-long class-action lawsuit.

The plaintiffs attempted to hold the platform responsible for losses caused by “scam tokens” traded on the Uniswap protocol. Judge Katherine Polk Failla of the Southern District of New York issued a ruling on Monday, dismissing the plaintiffs’ second amended complaint with prejudice, finding that they failed to state a valid legal claim. The court noted that the plaintiffs had multiple opportunities to amend their complaint but still could not prove that Uniswap was liable for misconduct by unnamed third-party token issuers.

The plaintiffs claimed to have suffered losses due to “rug pulls” and “pump-and-dump” schemes, arguing that Uniswap facilitated fraud by providing a platform for matching buyers and sellers. However, the court explicitly stated that merely providing a decentralized trading platform does not constitute “material assistance” in committing fraud. Judge Failla reaffirmed her previous stance that holding developers of smart contract code responsible for third-party misuse on decentralized platforms is “logically untenable.”

The case was initially filed in 2022, originally including federal securities law claims. Those securities claims were dismissed in 2023, and the Second Circuit Court of Appeals upheld that decision, remanding the remaining state law claims to the district court. This ruling marks the official end of the case and further clarifies the limits of state law liability for DeFi platform developers.
