Federal Court Fully Dismisses Fraud Case Against Uniswap
A federal court in New York has completely dismissed the class action lawsuit against DEX Uniswap and founder Hayden Adams, ruling that open-source developers are not liable for third-party fraud.
Judge Throws Out All Remaining Claims Against Uniswap
The U.S. District Court for the Southern District of New York has issued a final ruling in the class action lawsuit against decentralized exchange Uniswap and its founder Hayden Adams. Judge Katherine Polk Failla dismissed the case entirely, rejecting plaintiffs' demands for compensation over losses incurred trading fraudulent tokens on the platform.
A group of users had lost funds through scam projects listed on Uniswap, including classic Pump & Dump schemes and exit scams. The plaintiffs argued that Uniswap effectively aided bad actors by providing them a venue to find buyers for their fraudulent tokens.
Judge Failla rejected this reasoning outright. She ruled that holding the creators of smart contract code responsible for third-party abuse is absurd. Simply providing a functioning platform does not make developers complicit in fraud, the court determined.
Why This Matters
This ruling sets a significant legal precedent for the entire decentralized finance industry. The question of whether DeFi protocol creators bear responsibility for user actions remains one of the most contentious issues in crypto regulation. The court has now affirmed — twice — that open-source tool developers are not obligated to answer for those who misuse their technology.
The case had been ongoing since 2022. Back in 2023, the same court dismissed federal securities law claims against Uniswap. This latest ruling closes the matter completely: plaintiffs failed to prove either deception or unjust enrichment on the part of the protocol's creators.
Uniswap Labs Responds
Uniswap Labs Chief Legal Officer Brian Nistler called the decision precedent-setting for the DeFi sector. He emphasized that the court has now protected open-source code authors from liability for others' actions for the second time.
"Another day, another precedent-setting ruling for DeFi. Today, Judge Failla dismissed with prejudice the Risley class action against @Uniswap Labs and @haydenzadams. The Federal charges had previously been dismissed, and today the various state claims are dismissed. Again, the…" — Brian (@N0th1n3), original post
Protocol founder Hayden Adams also commented on the outcome, stating that when scammers exploit open-source smart contracts, the scammers themselves are responsible — not the developers. — Hayden Adams, original post

The Uniswap ruling fits into a broader trend of U.S. courts siding with crypto companies in platform liability disputes. In January 2026, the Securities and Exchange Commission withdrew its lawsuit against Bitcoin exchange Gemini. American courts are increasingly recognizing that technology providers should not bear the burden of policing every user interaction on their platforms.
