Key Takeaways
- Judge Katherine Polk Failla dismissed the remaining claims in the Risley class action with prejudice, ending the case in its current form.
- The court rejected attempts to hold Uniswap liable for misconduct by unidentified third-party token issuers based on “facilitation” theories.
- The outcome aligns with the Second Circuit’s earlier view that it “defies logic” to hold smart contract drafters liable for third-party misuse.
One of the most important U.S. courtroom tests of DeFi liability just hit a hard stop.
On March 2, 2026, Judge Katherine Polk Failla dismissed with prejudice the remaining claims in Risley v. Universal Navigation Inc., a class action that sought to hold Uniswap Labs and founder Hayden Adams liable for losses tied to alleged scam tokens traded via its ecosystem.
Uniswap’s head of policy Brian Nistler said the court again rejected liability theories “predicated on” Uniswap having “facilitated” scam trades by providing a marketplace that brings buyers and sellers together.
Hayden Adams called the outcome “good” and said scammers are responsible for scams, not open-source developers whose code gets misused.
The decision is a blow to a recurring theory in crypto litigation: that a protocol “facilitated” fraud simply by providing the venue and tools for trading.
Why the Ruling Matters Beyond Uniswap
“Facilitation” is the lawsuit equivalent of a blunt instrument.
If plaintiffs can turn “your software made it possible” into liability, then any neutral crypto plumbing becomes sue-first infrastructure:
- Wallets that route swaps.
- Remote Procedure Call (RPC) endpoints that broadcast transactions.
- Bridges that move assets across chains;
- even open-source libraries that power front ends.
The ruling matters because it’s been a repeated attempt to make that facilitation move stick.
And it keeps failing in this fact pattern—where the alleged wrongdoers are third parties and the protocol’s code executes user-authorized transactions.
The Second Circuit already set the tone in February 2025 when it affirmed dismissal of the federal securities claims and endorsed language that’s now basically a DeFi legal mantra:l it “defies logic” that the drafter of a smart contract could be held liable for a third party user’s misuse of the platform.
This March 2026 dismissal pushes the same idea into the “okay, and we’re done here” posture: with prejudice.
Why “With Prejudice” Changes The Temperature
A dismissal “with prejudice” is the court saying the claim, as brought, is not something you can fix by changing adjectives and filing again.
For DeFi builders, that matters because the Risley theory is a template plaintiffs could reuse: when fraud happens around a token, sue the platform that made trading possible.
If courts accepted facilitation as enough, protocol development becomes permanent litigation risk, especially for popular, composable systems that scammers inevitably touch.
When courts refuse that shortcut, the burden shifts back where it belongs: onto the alleged bad actors, and onto proof of something stronger than “you provided the code.”
What The Ruling Does—And Does Not—Mean For Mixers
This Uniswap win strengthens what you might call a software shield in civil cases.
Publishing general-purpose code that executes user-approved transactions is not, by itself, a magic hook for liability when unknown third parties commit fraud.
But crypto mixers tend to get litigated on a different theory: operation + intent + control, often in criminal law, not civil “facilitation.”
You can see the distinction in the U.S. Department of Justice (DOJ) own language in the Tornado Cash case.
In an August 2025 press release announcing Roman Storm’s conviction on an unlicensed money transmitting business conspiracy count, DOJ didn’t frame the case as “he wrote code.”
DOJ emphasized allegations of running the service: paying for infrastructure, promoting it, profiting, and continuing to provide the service with knowledge it was transmitting large volumes of criminal proceeds.
Likewise, DOJ’s 2023 announcement charging Tornado Cash founders framed the issue around money laundering and sanctions violations—again, not mere authorship in the abstract.
So the clean line is:
- DeFi DEX cases like Risley often hinge on whether “toolmaking” can equal liability for third-party wrongdoing. Courts are increasingly skeptical.
- Mixer cases often hinge on whether developers crossed from publishing software into operating a financial service that triggers licensing/sanctions/AML frameworks, plus what they knew and controlled.
Where the Pressure Moves Next
If facilitation keeps failing, plaintiffs and regulators don’t stop targeting crypto—they just get smarter about where to target.
Expect attention to concentrate on the human-controlled edges:
- Front ends (what’s shown, filtered, promoted).
- Token discovery and “curation” behaviors.
- Fee capture and governance levers.
- Marketing or solicitation language.
- aany operational chokepoint that looks like running a business.
DeFi’s best defense is the “infrastructure” framing. The minute a project looks like it is running a service, rather than shipping code, the legal analysis changes fast.
