1. Core evidence: The flow of funds is directed to official accounts; you cannot deny the validity of the transaction based solely on a platform’s statement;

2. Contract amendment rules: Any new clause must be mutually negotiated and confirmed in writing by both parties; unilateral additions have no legal effect;

3. Legal logic: If the counterpart conducts business in the platform’s name and the funds are deposited into the platform’s accounts, we have sufficient reason to believe the other party is authorized to act on behalf of the platform. Internal management loopholes within the platform cannot be used to stand against an external cooperation partner.
