Tron founder Justin Sun filed a federal lawsuit in California on April 21, 2026, against World Liberty Financial (WLFI), the DeFi project co-founded by Donald Trump and his sons Eric Trump and Donald Trump Jr., alleging the company secretly modified its smart contract to freeze approximately 2.9 billion of his tokens without notice or a governance vote.

Sun invested roughly $45 million in WLFI tokens between November 2024 and January 2025, making him the project's largest publicly known investor at the time. He also received 1 billion tokens in his capacity as a named project advisor. Those combined holdings are now frozen and worth approximately $75 million at WLFI's current price of around $0.026 per token. At the token's all-time high of $0.46, reached on September 1, 2025, the same position was valued at more than $1 billion. WLFI has since lost roughly 83% of its peak value and was trading near its all-time low as of April 19, 2026.

The lawsuit's central technical claim concerns a "blacklisting" function that WLFI quietly inserted into its smart contract in August 2025. A smart contract blacklist allows project administrators to lock specific wallet addresses, preventing those holders from moving or selling their tokens. Sun's legal filing states the company "buried it in the code without alerting token holders to its existence." His wallet was frozen in September 2025 with no public announcement and no governance vote by WLFI's roughly 145,000 token holders.

Sun alleges five categories of wrongdoing: fraudulent inducement (he claims Trump's association was used as a material selling point to attract investment), unlawful asset seizure, removal of his voting rights under the project's governance structure, coercion, and market manipulation. On the coercion allegation, the filing claims that WLFI co-founder Chase Herro threatened to burn Sun's tokens and report him to U.S. authorities over fabricated KYC (Know Your Customer) violations if Sun refused to continue investing or mint $200 million worth of WLFI's USD1 stablecoin, a dollar-pegged token central to the project's commercial strategy. Sun also argues that freezing his wallet artificially propped up WLFI's price by preventing a major holder from selling into the market. A WLFI spokesperson reportedly characterized the claims as "meritless."

In court filings and public statements, Sun has been deliberate about separating Trump personally from the project's management. "I do not believe President Trump would condone these actions if he knew about them," he wrote. He told Decrypt: "All I want is to be treated the same as every other early investor who received tokens, no better, no worse." He also told CoinDesk: "I tried in good faith to resolve this situation." Sun has publicly opposed a WLFI governance proposal published on April 15 that would unlock 62.28 billion currently locked tokens but require early investors to burn 10% of their allocations as a precondition for participating.

The lawsuit lands amid a string of governance failures at WLFI. On April 9, CoinDesk reported that WLFI's CTO, Corey Caplan, used 5 billion WLFI tokens from project reserves to borrow $75 million in stablecoins from Dolomite, a DeFi lending platform he co-founded, trapping other depositors and sending WLFI's price down roughly 15%. Bloomberg reported on April 12 that a broader "investor revolt" was forming over the project's opacity. A Trump business entity owns 60% of WLFI equity and collects 75% of all token sale revenue. The Trump family had reportedly taken in $1 billion from token sales by December 2025, while still holding an estimated $3 billion in unsold supply. The UAE Royal Family separately acquired a 49% stake in the project in a deal signed before Trump's second inauguration, adding further complexity to WLFI's ownership structure and its international entanglements.

For users outside the United States, particularly in South Asia, the lawsuit carries concrete policy implications. In January 2026, Pakistan signed a formal agreement with WLFI to integrate USD1 into its domestic payments framework, with an initial target of $1 billion in stablecoin-facilitated cross-border transactions. The deal was negotiated by Zach Witkoff on WLFI's side and Finance Minister Muhammad Aurangzeb on Pakistan's side. Pakistan receives more than $30 billion annually in remittances, and the USD1 pilot was framed as infrastructure for those payment corridors. Pakistan also lifted an eight-year banking ban on crypto in April 2026, a move the government publicly connected to its WLFI partnership as well as a concurrent Binance partnership. The Sun lawsuit's technical disclosures raise a live regulatory question: whether a stablecoin whose underlying contract can be silently modified and whose major holders can have their wallets frozen without a governance vote can serve reliably as a neutral payments layer. The case record, covering hidden admin functions, upgrade proxies, and blacklist capabilities, is already drawing scrutiny from developers in Nigeria, India, and other markets weighing WLFI or USD1 integrations.

The lawsuit was filed in California federal court, where it awaits scheduling. Sun settled a separate SEC fraud case in March 2026, with his company, Rainberry Inc., paying a $10 million fine and no admission of wrongdoing. That case had originally been paused in February 2025 before the settlement was reached the following year. Senators Elizabeth Warren and Richard Blumenthal have publicly questioned whether Sun's heavy investment in Trump-linked crypto ventures influenced both the pace and the outcome of that settlement, with critics calling the arrangement a "pay-to-play" dynamic. Amanda Fischer of Better Markets went further, describing the terms as amounting to a "gag order" on a major defendant.
