With the rapid development of blockchain technology, the concept of Web3 is gradually coming to the forefront, becoming an important component of the future internet. Web3 is not just a technological update to the existing internet; it also grants users more control, privacy protection, and autonomy. Under the framework of Web3, an increasing number of enterprises are beginning to apply decentralized concepts to practical business operations, with the points mall being a key application scenario.

The core of a Web3 points mall is a decentralized mall platform built on blockchain technology, where users can purchase goods, participate in activities, and earn points rewards. These points can not only be used to redeem goods but can also be stored and transferred on the blockchain, enabling cross-platform and cross-application interoperability.

However, achieving this goal requires more than just the Web3 framework. The smart contract modules necessary for implementing a Web3 points mall are indispensable, as they provide the decentralized, transparent, and tamper-proof trust foundation for the entire system. This article will detail the essential smart contract modules in the development of a Web3 points mall, helping developers better understand how to meet the functional requirements of the mall through smart contracts.

I. The Role of Smart Contracts in Web3 Points Malls

Smart contracts are programs that automatically execute, control, or document legally relevant events and actions. Their emergence has expanded blockchain technology beyond digital currency transactions to a wider range of application scenarios. In Web3 points malls, smart contracts play several important roles, including:

1. Points Management: Smart contracts record and manage each user's points account in a decentralized manner, including operations such as issuing, increasing, decreasing, and redeeming points.

2. Reward Distribution: The mall's points reward system is typically linked to actions like purchasing goods or participating in activities. Smart contracts can help automatically calculate and distribute the points users deserve.

3. Goods Redemption: Users redeem goods using accumulated points. Smart contracts verify the legitimacy of redemption requests and update the corresponding points balance.

4. Cross-Platform Interoperability: Due to the decentralized nature of Web3, points from the points mall can be interoperable across different platforms. Smart contracts provide the necessary cross-platform compatibility and security for these operations.

5. Transparency and Traceability: The execution process of smart contracts is open and transparent. All points issuance and redemption records can be publicly queried, ensuring fairness and trust.

II. Essential Smart Contract Modules for Web3 Points Malls

To realize the various functions of a Web3 points mall, developers need to design and develop multiple smart contract modules. The following are some core smart contract modules that form the basic framework of a Web3 points mall.

1. Points Contract (Token Contract)

The points contract is one of the most fundamental and important modules in a Web3 points mall. It is responsible for the creation, management, and transfer of points. Developers can customize the functions of the points contract as needed, with common features including:

• Points Minting: Administrators or the system can mint points for users according to the mall's rules.

• Points Transfer: Users can transfer points to other users, supporting peer-to-peer points transfers.

• Points Balance Query: Users can query their current points balance in their account.

• Points Burning: When points are no longer needed or errors occur, they can be burned to reduce the total supply.

When implementing a points contract, developers can refer to standard token protocols like ERC20 or ERC721 and extend them based on the mall's requirements. For example, features such as points expiration time or spending limits can be added on top of ERC20.

2. User Account Contract (Account Contract)

The user account contract is responsible for managing user information in the mall. In addition to points balance, users' personal information, points history, and redemption records can also be stored in the account contract. Its main functions include:

• User Registration and Authentication: When a new user registers, the smart contract creates an account for them and records relevant information, such as wallet address and points account.

• Points History Query: Every points issuance, redemption, and transfer action is recorded in the user account contract, allowing users to query their points operation history at any time.

• Redemption Records: When users redeem goods or services, the account contract updates the redemption records for future queries and reconciliation.

Through the user account contract, user behavior can be traced on the blockchain, preventing potential cheating behaviors that might occur in traditional mall platforms.

3. Reward Contract (Reward Contract)

The reward contract is the module used in Web3 points malls for automatically distributing points rewards. In traditional malls, points rewards are often allocated based on purchase amounts, activity levels, or participation in events. In Web3, the reward contract automates these tasks through smart contracts, ensuring fairness and transparency in reward distribution.

The functions of the reward contract typically include:

• Purchase Points Rewards: When users purchase goods, the smart contract distributes points rewards to users according to the mall's set ratio.

• Activity Participation Rewards: When users participate in mall activities (such as lotteries or promotions), the reward contract automatically calculates and distributes the corresponding points.

• Regular Incentives: Some points malls design regular user incentive activities, and the reward contract can automatically distribute rewards based on time.

4. Redemption Contract (Redemption Contract)

The redemption contract is responsible for handling the process of users redeeming goods with points. The core function of this contract is to ensure the legitimacy of redemption operations and manage the inventory of goods. Its basic functions include:

• Redeem Goods: Users use a certain amount of points to redeem goods. The redemption contract verifies whether the user's points balance is sufficient and deducts the corresponding points.

• Goods Inventory Management: For each product, the redemption contract records its inventory quantity, ensuring that the product stock in the mall is valid during each redemption.

• Redemption Rules: Some products may have redemption restrictions (such as redemption within a specific time frame or limited quantities). The redemption contract performs corresponding validations based on these rules.

5. Cross-Chain Contract (Cross-chain Contract)

In the world of Web3, decentralized applications (DApps) often involve cross-chain operations. Points and goods on different blockchain platforms may need to be interoperable, and cross-chain contracts are designed for this purpose. They enable the transfer and redemption of points across different blockchain platforms.

The functions of cross-chain contracts include:

• Cross-Chain Points Transfer: Users can transfer points from one platform to another for cross-chain redemption.

• Cross-Chain Goods Redemption: If the mall's goods can be redeemed across different blockchain platforms, the cross-chain contract handles the synchronization and validation of the redemption.

6. Governance Contract (Governance Contract)

Web3 points malls often require a certain degree of decentralized governance mechanisms, and the governance contract is the core module for achieving this function. The governance contract allows users to participate in the management and decision-making of the mall through voting, ensuring that the mall operates fairly and justly. The functions of the governance contract include:

• Decision Voting: Users can participate in the governance decisions of the mall, such as adjusting points rules or modifying redemption ratios.

• Community Incentives: Incentivize users to participate in governance voting through methods like token rewards.

III. Summary

The smart contract modules of a Web3 points mall are the core components of the entire system, providing a transparent, fair, and trustworthy transaction environment through decentralization. Developers need to design and implement a series of smart contract modules based on the mall's actual requirements, including points contracts, user account contracts, reward contracts, redemption contracts, cross-chain contracts, and governance contracts. These modules not only form the foundation of the mall's operation but also provide users with higher security, privacy protection, and a better experience.

With the continuous development of Web3 and blockchain technology, smart contracts will play an even more important role in Web3 points malls. The future points mall will no longer be an extension of traditional centralized malls but a fully decentralized, autonomous system that truly realizes user control and privacy protection.
