Justin Sun alleges USD1 backdoor in $45M WLFI lawsuit

Tron founder Justin Sun alleged World Liberty Financial's USD1 stablecoin contains an admin backdoor allowing operators to transfer user funds without consent, escalating his $45 million lawsuit. Sun, an early investor who helped push WLFI's token sale past $550 million, said the permission structure lets operators move USD1 from specific accounts to operator-controlled or third-party wallets, bypassing user approval.

"The most critical issue is that cold wallets or multisignature wallets cannot block such transfers," Sun said, pointing to a discrepancy between the code published on World Liberty's official GitHub and the code running on the live USD1 system. He said the backdoor function was added without WLFI token holder approval, reportedly before the WLFI token launch.

USD1 is a dollar-pegged stablecoin issued by World Liberty Financial, designed to maintain a 1:1 value with the US dollar for transactions and savings. Sun's complaint alleges World Liberty built hidden backdoor functions into both the WLFI token and USD1 smart contracts, giving the team power to freeze, restrict, or burn any holder's tokens without notice. He claims the capability was used against his own token holdings and that he faced threats of criminal referrals after asserting his legal rights. USD1 trades at $0.99960, holding its peg, while WLFI trades at $0.063 and TRX at $0.342, according to CoinGecko data.

The allegations carry implications beyond the lawsuit. USD1's reported $4 billion market cap reflects user-deposited collateral, not company funds that could satisfy a judgment, Sun said. A California federal judge ruled Aug. 20 that Sun's individual claims will proceed in open court, rejecting World Liberty's push to move the dispute into private arbitration.

Court Ruling Splits the Case

The ruling in Sun et al v. World Liberty Financial LLC, No. 3:26-cv-03360-JD, before Judge James Donato in the Northern District of California, ordered the parties to determine which company-related claims stay in court and which move to arbitration. Sun called the decision a "major victory" for transparency.

World Liberty co-founder Zach Witkoff disputed Sun's account, saying the judge issued no formal rulings on Aug. 20 and that most company-related claims must go to arbitration per the public docket. Witkoff called Sun's post "riddled with falsehoods." The public docket had not shown a written order as of Aug. 22.

Sun also obtained a court order blocking World Liberty from destroying his tokens, arguing the order was necessary given the alleged threats and the technical capability to act on them. He said other investors have privately described similar concerns but remain hesitant to file suit, attributing that hesitation to fear of retaliation.

Solvency and Governance Questions

Sun has questioned whether World Liberty has enough capital to cover a judgment. Public reports cited in the dispute state World Liberty deposited roughly five billion WLFI tokens as collateral on Dolomite, a lending platform co-founded by World Liberty's own chief technology officer. Analysts have compared the circular borrowing structure to patterns seen before the FTX collapse.

Sun also referenced World Liberty co-founder Chase Herro's earlier project, Dough Finance, which claimed a hack occurred but faced an investor lawsuit alleging Herro personally moved the funds. Public reporting indicates most of those assets remain unaccounted for.

World Liberty Financial has not publicly responded to the backdoor and solvency claims. The dispute highlights the need for transparent audits and community oversight in stablecoin operations, as centralized control mechanisms face increasing scrutiny from regulators and users alike. If Sun's allegations are confirmed through discovery, the case could pressure transparency standards across the stablecoin sector, which has grown into a multi-billion-dollar market with issuers including Tether and Circle competing for dominance.
