🖋️Signature and Sigpage

Functions and Usages

A Signature Page is a component smart contract, by inheriting which Investment Agreement and Shareholders Agreement can obtain their members, attributes and methods. The signature page consists of a number of signature blank, each of which is used to sign by a specific party, and each signature represents the express consent of parties, while the signature blank and the block number where the signature is located are the time identifiers, aiming to confirm and query the time information that users have expressively agreed or exercising rights. The signatures of all parties represent the formation of the contract, which is the premise for submission to the general meeting of shareholders. The signature page of an investment agreement also serves the purpose of locking in underlying shares related to the parties. Specifically, when the seller signs the contract, the system will automatically lock the clean paid-in contribution of the underlying share with the same amount in the share register, thus avoiding the situation where one share is traded repeatedly.

For special shareholders' rights that may increase the number of parties to the investment agreement, such as drag-along option and tag-along option, the system will automatically add the signatures blanks to the additional signature page, and add the relevant signatures according to the time when the parties exercise their rights or make promises. Therefore, both the investment agreement and the shareholders' agreement include two signature pages, the initial signature page and the additional signature page.

Members and Attributes

The main members of the signature page are the signature object, the signature blank object, the signature blank mapping with the structure "user number -> signature blank object", and the list of user numbers of the buyer and the seller.
