In addition, according to Article 54 of the Contract Law, one party has the right to request the people's court or arbitration institution to modify or terminate the following contracts:

Although account transaction is a new thing, there are few such contracts. However, considering whether the contract is valid, we must consider whether the subject matter of the contract is legal. The transfer of property rights of game accounts should be based on the object of property rights in the Property Law. The object of property right is specific and independent, not limited to tangible things. The property right of your transaction belongs to the object of property right and can be protected by law.
After the transaction, all the information has been modified, and it is estimated that the other party will not get it back.
