In the rapidly evolving world of Web3 and non-fungible tokens (NFTs), collection models play a foundational role in organizing digital assets, verifying ownership, and providing essential metadata for creators and collectors alike. Whether you're building on decentralized marketplaces or integrating NFT data into your application, understanding how collections are structured is crucial.
A collection represents a group of digital assets—typically NFTs—originating from one or more smart contracts. These collections allow users to categorize items from the same creator or project, making it easier to discover, trade, and manage assets across blockchain ecosystems. Each collection can have multiple owners and is enriched with metadata such as creator royalties, descriptions, and social links.
For example, the OKX Football Cup is a real-world representation of an NFT collection displayed on OKX, showcasing how digital collectibles can be grouped, verified, and explored through structured data models.

What Is a Collection Model?
The Collection Model serves as the backbone for representing NFT projects within a Web3 environment. It encapsulates all relevant information about a specific collection, enabling platforms to display, analyze, and interact with NFTs efficiently.
Below are the core components of the Collection Model:
Core Properties of a Collection
name(String)
The official name of the collection, used for identification and display purposes.des(String)
A detailed description that provides context about the collection’s theme, purpose, or artistic vision.image(String)
A URL pointing to the logo or primary visual asset representing the collection.backgroundImage(String)
The background image associated with the collection, often used in gallery or profile views.slug(String)
A unique identifier derived from the collection name, commonly used in URLs for easy referencing (e.g.,okx-football-cup).certificateFlag(Boolean)
Indicates whether the collection has been officially verified or certified by the platform, adding trust and authenticity.officialWebsite(String)
The official website link for the project behind the collection.Social Media Links
Includes:instagramUrldiscordUrlmediumUrltwitterUrl
These help users connect with the community and stay updated on project developments.
categoryList(Array)
Tags or categories that classify the collection (e.g., Art, Sports, Gaming), improving discoverability.assetContracts(Array)
An array of Asset Contract Models linked to this collection. This field reveals which blockchain contracts contribute assets to the collection.stats(Object)
A nested object containing key performance metrics of the collection, based on the Collection Stats Model.
Understanding these parameters enables developers and analysts to build dynamic interfaces that reflect real-time NFT activity and user engagement.
Understanding the Asset Contract Model
Each NFT within a collection originates from a smart contract deployed on a blockchain. The Asset Contract Model defines the technical and operational details of these contracts.
Key Fields in the Asset Contract Model
chain(String)
Specifies the blockchain network where the contract resides (e.g., Ethereum, OKC).contractAddress(String)
The unique address of the smart contract on the blockchain. This is essential for querying token data and verifying authenticity.tokenStandard(String)
The protocol standard used by the contract—commonlyERC-721for unique tokens orERC-1155for semi-fungible tokens.ownerAddress(String)
The wallet address that currently owns or manages the contract.erc2981(Boolean)
Indicates whether the contract supports the ERC-2981 royalty standard, ensuring creators receive royalties on secondary sales.
This model ensures transparency and interoperability across platforms by standardizing how contract-level data is accessed and interpreted.
Exploring the Collection Stats Model
To evaluate a collection's market performance and popularity, platforms rely on quantifiable metrics provided by the Collection Stats Model. These statistics empower users to make informed decisions when buying, selling, or analyzing NFTs.
Key Metrics in Collection Statistics
latestPrice(String)
The most recent sale price recorded for any item in the collection, denominated in ETH or other native tokens.totalVolume(String)
The cumulative trading volume of the collection across all transactions—a key indicator of market activity.totalCount(String)
The total number of NFTs minted within the collection.ownerCount(String)
The number of unique wallets holding at least one NFT from the collection.floorPrice(String)
The lowest current asking price among all listed items in the collection—often used as a benchmark for valuation.
These stats are vital for traders, analysts, and collectors who monitor trends and assess investment potential in the NFT space.

Frequently Asked Questions (FAQ)
Q: What is the purpose of a collection slug?
A: A slug is a URL-friendly version of the collection name, used to create clean, shareable links. For example, "OKX Football Cup" becomes "okx-football-cup" in URLs.
Q: How does certification affect a collection’s credibility?
A: A certificateFlag set to true indicates that the platform has verified the legitimacy of the collection, reducing risks of scams or impersonation.
Q: Why is ERC-2981 support important for NFT collections?
A: ERC-2981 allows creators to automatically receive royalties on secondary market sales. Collections supporting this standard promote fair compensation for artists and developers.
Q: Can one collection include contracts from multiple blockchains?
A: Yes. The assetContracts array can include contracts from different chains, allowing cross-chain collections that aggregate NFTs from various ecosystems.
Q: How often are collection stats updated?
A: Stats like floor price and trading volume are typically updated in real time or near-real time to reflect live market conditions.
Q: What makes a collection discoverable on NFT marketplaces?
A: Factors include accurate categorization (categoryList), rich metadata (des, image, social links), verification status (certificateFlag), and active trading volume.
Why These Models Matter for Developers and Creators
For developers integrating NFT functionality into apps, games, or marketplaces, standardized models like Collection, Asset Contract, and Stats ensure consistency and reliability. They enable seamless fetching of metadata, verification of ownership, and display of real-time analytics.
For creators launching new NFT projects, properly structured collections enhance visibility, trustworthiness, and long-term value. Including complete descriptions, verified links, and royalty configurations supports both community growth and sustainable monetization.
