From the perspective of the page, the "small agreement" is very simple to use, fill in the agreement name and the contents of the agreement text, and then pay the service fee to generate the agreement. The minimum fee for an ordinary agreement is 3 yuan. The more the agreement word number, the higher the fee. If you choose to double the cost of the cryptographic service, the cost is mainly used to write the blockchain and you need to pay the miner's fees.
The official stated that the small agreement is a true decentralization technology. After the parties confirm the agreement, the small agreement will construct a signature and write the agreement into the Ethernet network. And the small protocol is authenticated by WeChat ID. Each WeChat user has a unique and fixed ID in the small protocol. This ID is associated with the specific WeChat user's contact number, ID number, and bank card.
