A San Francisco federal judge has blocked World Liberty Financial's attempt to move Justin Sun's lawsuit into private arbitration, keeping the dispute public and opening the door to scrutiny of the company's USD1 stablecoin and its controversial freeze functions. The ruling on August 21 means Sun's individual claims will proceed in federal court rather than under confidential arbitration rules, potentially exposing details about how the Trump family crypto venture manages its stablecoin and token operations.

The case centers on a blacklist function World Liberty added to its WLFI token contract in August 2025, which the company used days later to freeze 600 million tokens that Sun had been cleared to trade. Sun, the founder of the TRON blockchain, paid $45 million for 3 billion WLFI tokens in two tranches. When World Liberty unlocked 20 percent of early purchasers' holdings on September 1, 2025, releasing Sun's tokens for trading, the company blacklisted the wallet holding them within days, and they remain frozen.

Why Does This Matter for Stablecoin Regulation?

The public court proceedings could expose how World Liberty built freeze capabilities into USD1, its stablecoin, raising questions about centralized control that regulators and stablecoin users increasingly scrutinize. Sun's lawyers argued that World Liberty waived its right to arbitration by suing him for defamation in Florida state court, claiming he made false statements about the company's authority to freeze tokens. The judge agreed to keep Sun's personal claims public, though World Liberty's motion to arbitrate claims by Sun's two British Virgin Islands entities remains under review.

USD1 has grown to approximately $4 billion in supply across multiple blockchains, with $1.51 billion on Ethereum, $1.40 billion on BNB Chain, and $1.06 billion on Solana, according to data cited in the source material. The stablecoin's issuance is shifting: the U.S. Office of the Comptroller of the Currency granted preliminary conditional approval on August 14 to World Liberty Trust Company, National Association, to take over USD1 issuance and custody from BitGo Bank & Trust.

What Are the Key Issues in Sun's Complaint?

Sun's lawsuit alleges that World Liberty amended the WLFI contract without governance votes or disclosure to enable blacklisting. The complaint lists seven counts under Delaware law and federal jurisdiction, including breach of contract, fraud in the inducement, conversion, unjust enrichment, and breach of the implied covenant of good faith and fair dealing. Sun also raised a defamation claim after World Liberty stated that 272 wallets had been blacklisted, with 79 percent tied to phishing attacks and one suspected of misappropriation.

A May 25 stipulation bars World Liberty from burning, destroying, or reallocating Sun's tokens, and this protection lapses if the company wins on any dispositive motion or motion to compel arbitration. Sun's lawyers at Cahill Gordon & Reindel and Keker, Van Nest & Peters argued that the November 2024 token purchase agreement carries an exclusive forum clause requiring any proceeding "arising out of or based upon" it to proceed in federal or California state court, not arbitration.

"Rather than acting in good faith, Justin Sun chose to defame World Liberty, repeatedly, publicly, and to millions of followers," said Tom Clare, counsel to World Liberty Financial.

How Do Stablecoin Freeze Functions Compare Across Issuers?

• Tether's USDT: Carries freeze functions that the issuer uses to act on law enforcement requests, giving Tether centralized control over token movement.
• Circle's USDC: Also includes freeze capabilities that Circle deploys in response to regulatory or law enforcement directives, similar to Tether's approach.
• World Liberty's USD1: Built the same freeze capability into its stablecoin, though the company has not publicly detailed the governance or oversight mechanisms for deploying this function.

The freeze function debate highlights a broader tension in stablecoin design: centralized control enables rapid response to fraud and regulatory compliance but also concentrates power in the issuer's hands. Sun's public court case will likely expose how World Liberty justifies and manages this capability, setting potential precedent for how regulators view stablecoin freeze functions going forward.

Sun's solvency concerns about World Liberty rest partly on the company's collateral arrangements. In April, World Liberty deposited roughly 5 billion WLFI tokens as collateral on the Dolomite lending market and borrowed $75.7 million in stablecoins, with $65.4 million in its own USD1. Dolomite currently shows $310.7 million borrowed across chains, with $296.6 million on Ethereum, according to data from DefiLlama.

The WLFI token itself has experienced significant volatility. It traded at $0.0616 late on August 21, up 2.9 percent over 24 hours, but sits 81 percent below the $0.3313 it reached on September 1, 2025, its first day of trading. The token is 21 percent above its record low of $0.0508 set on August 9.

What Happens Next in the Litigation?

Briefing on World Liberty's separate motion to dismiss the complaint has been stayed since June 5, and the court vacated the case management conference scheduled for July 23, meaning no discovery schedule is currently set. The judge set argument on the arbitration motion for Thursday, August 21, in Courtroom 11 of the Northern District of California, though no written order had been entered as of the docket's last update. Sun's public post on X describing the ruling remains the only public account of what the judge said, as of the source material's publication date.

The outcome could reshape how stablecoin issuers manage freeze functions and token holder disputes. By keeping Sun's claims in public court, the judge has ensured that details about World Liberty's governance, collateral practices, and stablecoin operations will become part of the public record, potentially influencing how regulators and other stablecoin projects approach similar issues.
