CoinWorld.com reports that the cooperation between World Free Finance and Sun Yucheng has evolved into a legal dispute, involving the freezing of tokens and mutual accusations. On May 4, 2026, World Free Finance filed a defamation lawsuit against Sun, accusing him of launching a public attack after the company restricted his access to its WLFI tokens. On April 21, Sun also filed a lawsuit against World Free Finance, accusing it of illegally freezing the tokens he holds and preventing him from voting. Sun previously invested $30 million in November 2024, later increasing to $75 million. With the launch of WLFI token trading, relations between the two parties deteriorated, and Sun’s token transfers were accused of market manipulation. World Free Finance claims it has the right to freeze tokens, while Sun says this is an illegal asset seizure. The two lawsuits may take months or even years to resolve, and the court will review items such as investor agreements, smart contract disclosures, and token transfer records.
