Cryptocurrency billionaire Sun Yat-sen has filed a lawsuit against World Liberty Financial, accusing the company of fraud, theft, and unauthorized technical upgrades. The lawsuit, filed on Tuesday, targets Chase Herro, co-founder of World Liberty, labeling him a habitual fraudster and tax evader. Sun claims that World Liberty Financial is on the brink of collapse and potential bankruptcy. The complaint alleges that World Liberty Financial secretly completed two technical upgrades last year without a governance vote, allowing the company to freeze and seize WLFI tokens. Sun describes these actions as destructive, while World Liberty Financial maintains that the freeze function is used to protect user rights. Additionally, the lawsuit accuses the company of operating an unlicensed money transmission business, violating federal and state laws. World Liberty Financial's CEO, Zach Witkoff, dismissed the lawsuit as a diversion from Sun's own misconduct. The company also cited Sun's purchase of $100 million worth of TRUMP meme coins as a factor in their decision to freeze his WLFI tokens, although the complaint suggests this purchase was pre-approved by a Trump family member involved in both projects.
