The platform's own funds exceed $1.4 billion, which includes approximately $464 million in the user protection fund. The platform will continue to uphold the security commitments made when the protection fund was established in 2022, planning to replenish the fund to the baseline of $300 million within a week."The protection fund is not just a slogan, but an important mechanism that provides tangible security for users in the event of extreme security incidents," Gracy stated.
