III. Core Functional Modules of NFT DApps

When developing an NFT marketplace, the following core functional modules are typically required:

1. NFT Minting

NFT minting is one of the key functions in an NFT DApp. Users can create their own NFTs through the DApp and store them on the blockchain. This process usually requires calling smart contracts.

The minting process typically includes the following steps:

• Upload digital assets (such as images, videos, audio, etc.).

• Fill in the NFT's metadata (such as name, description, tags, etc.).

• Set the NFT's unique identifier and attributes.

• Complete the NFT minting and put it on the blockchain.

2. Marketplace Trading

The NFT marketplace is the most important component of an NFT DApp. Marketplace functions typically include:

• Browsing NFTs: Users can browse NFTs by category and view detailed information.

• Buying and Selling: Users can list their NFTs for sale or purchase NFTs from other users.

• Auction Functionality: Some platforms also offer auction features, allowing users to trade through bidding.

• Transaction History: Users can view the transaction history of each NFT, including sale prices, buyers, sellers, and other information.

3. Wallet Integration

Wallet integration is an essential function for any blockchain application. NFT DApps typically need to integrate with digital wallets, allowing users to store and manage their NFT assets. Common blockchain wallets include MetaMask, Trust Wallet, Coinbase Wallet, etc.

4. Smart Contracts

Smart contracts are the core of NFT DApps, ensuring the automatic execution and security of operations such as NFT creation, trading, and transfer. Smart contracts typically include:

• Minting Contracts: Used to create NFTs and store them on the blockchain.

• Trading Contracts: Used to execute the buying and selling of NFTs.

• Royalty Contracts: Used to ensure NFT creators receive a certain percentage of royalties from each transaction.

5. Search and Filtering Functions

To enhance the user experience, NFT marketplaces typically need to provide powerful search and filtering functions to help users quickly find NFTs of interest. These functions include:

• Filtering by category, price, collector, creator, etc.

• Sorting by time, popularity, trading volume, etc.

IV. Development Steps for NFT DApps

Developing a complete NFT DApp involves multiple steps, including frontend, backend, blockchain, and smart contract development. The following is a general development process:
