Electronic contract is a form of contract, which refers to an electronic agreement that clarifies the rights and obligations of both parties in the form of data messages for the purpose of safeguarding rights and fulfilling contracts under network conditions.

In the electronic contract, the signature and seal you see are only the appearance of the electronic signature, and it is the digital signature (digital certificate) that can really judge the legal effect of the electronic contract. By checking whether the digital certificate is complete, we can quickly identify whether the electronic contract has been tampered with, so as to judge whether it is valid.
