After nearly four years in court, Uniswap Labs and its founder Hayden Adams have secured a final dismissal in a class action lawsuit filed in 2022.
On March 2, Judge Katherine Polk Failla of the Southern District of New York dismissed the remaining claims against Uniswap Labs with prejudice. This means the plaintiffs cannot refile the same claims in federal court. The decision effectively closes one of the most closely followed legal cases involving a decentralized exchange.
The lawsuit had sought to hold Uniswap responsible for investor losses tied to scam tokens traded on its protocol.

What the Lawsuit Was About
The plaintiffs argued that Uniswap Labs should share liability for losses caused by “rug pulls” and pump-and-dump schemes conducted by third-party token issuers. Their position was that by operating the protocol and collecting fees, Uniswap facilitated fraudulent activity.
Judge Failla rejected that argument. In her ruling, she stated that it would defy logic to hold a developer of computer code liable for a third party’s misuse of that software. The court emphasized that providing a neutral, open-source platform does not amount to substantial assistance in fraud.
The decision compared Uniswap’s role to that of traditional service providers. Simply offering infrastructure that can be used for lawful or unlawful purposes does not automatically create liability for misconduct carried out by users.
Federal claims were dismissed with prejudice, while certain state-law claims were dismissed without prejudice. The ruling follows earlier developments in appellate court that also favored Uniswap’s position.

Broader Implications for DeFi
The outcome is widely seen as a significant legal development for decentralized finance. By reaffirming that open-source smart contract developers are not automatically responsible for third-party misconduct, the ruling provides greater clarity around liability in decentralized systems.
The decision may serve as a reference point in future cases involving decentralized protocols and developer responsibility. However, it does not eliminate regulatory scrutiny of the sector, and questions remain around how other aspects of decentralized platforms may be treated under U.S. law.

Market Reaction
Following the ruling, Uniswap’s native token UNI rose more than 6%, briefly trading above $3.92. The initial rally reflected reduced legal uncertainty surrounding the protocol.
However, the gains proved short-lived. UNI has since fallen back below $3.80, returning closer to pre-ruling levels. The broader crypto market environment, geopolitical uncertainty and macroeconomic factors continue to influence price action.
