Justin Sun has accused Hong Kong trust company FDT of unauthorized collaboration with Dubai's Aria DMCC to misappropriate $500 million in TUSD reserves. Sun claims that FDT, entrusted by Techteryx to manage the funds, engaged in fraudulent activities including document forgery and creating false accounts to divert the funds to unlicensed private entities instead of the agreed Cayman-licensed fund. Utilizing Dubai DIFC's new mechanisms, Sun's team secured a global freezing order after five months, freezing the first-tier bank accounts involved and continuing to trace the funds through subsequent layers. FDT denies the allegations, accusing Sun of defamation.
