The IOUs on WeChat are legally binding if they conform to the law. However, because the evidence form and effect of WeChat may be controversial, it is suggested that some additional measures should be taken to protect the rights and interests of both parties when using WeChat to conduct transactions and sign agreements.

First of all, when using WeChat to conduct a transaction, it is suggested that both parties confirm the content and conditions of the transaction through a clear written agreement. This written agreement may include the identity information of both parties, transaction contents, payment method, liability for breach of contract, etc. After signing a written agreement, you can save the agreement on WeChat by scanning or taking photos, which is convenient for reference at any time.

Secondly, when signing a written agreement, it is suggested that both parties adopt real-name authentication to clarify the rights and obligations of both parties in the agreement. In addition, it is suggested that the dispute settlement method, such as arbitration or litigation, be stipulated in the agreement in order to solve the dispute in time.

Finally, if the IOUs on WeChat involve money disputes, it is suggested that both parties conduct transactions through bank transfer or third-party payment platform, and keep relevant transaction records and vouchers. In case of dispute, these records and vouchers can be used as evidence.

To sum up, the IOUs on WeChat are legally binding, but some extra measures should be taken to ensure the rights and interests of both parties. When using WeChat to conduct transactions and sign agreements, it is recommended to adopt a clear written agreement, real-name authentication, agreed dispute resolution and keep relevant transaction records and vouchers. When using WeChat to conduct transactions and sign agreements, we need to take some extra measures to ensure the rights and interests of both parties. The rights and interests of both parties can be effectively protected through clear written agreement, real-name authentication, agreement on dispute resolution and keeping relevant transaction records and vouchers. At the same time, once a dispute occurs, it can be resolved through legal channels to ensure that the legitimate rights and interests of both parties are protected.

Third, the legal basis

According to the Contract Law of People's Republic of China (PRC), a contract is an agreement between the parties to establish, change and terminate a civil relationship. Contracts established according to law are protected by law. Therefore, the IOUs on WeChat are legally binding if they comply with the law. In addition, People's Republic of China (PRC) Electronic Signature Law also stipulates the legal effect of electronic signatures, which provides legal protection for the IOUs on WeChat.
