Core Viewpoint - The article emphasizes the importance of using a legally valid electronic contract for personal transactions to mitigate risks associated with buying and selling second-hand items, such as disputes over product quality and payment issues [1]. Group 1: Risks in Personal Transactions - Three main risks in personal transactions are identified: 1. Legality of contract templates: Many online agreements lack completeness and legal validity [1]. 2. Complicated filling process: Manual entry of product information and transaction rules is time-consuming [1]. 3. Lack of evidence for disputes: Private transactions often lack documentation, making it difficult to hold parties accountable [1]. Group 2: Core Protections Offered by the Contract - The contract provides three core protections: 1. Professional contract templates that are legally valid, covering essential terms such as product details, transaction amount, delivery time, inspection rules, and breach of contract responsibilities [1]. 2. Quick contract generation with a simplified process, allowing users to fill in necessary information easily and preview the contract before signing [1]. 3. A complete evidence chain for rights protection, including real-name verification and comprehensive documentation of the signing process [1]. Group 3: Application Scenarios - Suggested application scenarios for the contract include: 1. Second-hand electronics: Contracts can specify inspection timelines and return policies [1]. 2. Furniture transfers: Agreements can outline pickup responsibilities and damage liabilities [1]. 3. Concert ticket sales: Contracts can detail seat numbers and non-refundable terms [1]. Group 4: Operational Steps - The process to complete a secure transaction involves three steps: 1. Accessing the "Law Dada Electronic Contract" mini-program and selecting the "Goods Sale" contract template [1]. 2. Filling in the contract details based on actual needs [1]. 3. Previewing the contract and initiating the signing process [1]. Group 5: Advantages of Using Law Dada - The advantages of using Law Dada include: 1.
