What Is the OKX NFT Marketplace?

OKX NFT Marketplace is a decentralized, multi-chain NFT exchange that aggregates listings from top platforms including OpenSea, Magic Eden, LooksRare, IMX, and X2Y2. This unified approach ensures users access the deepest order books and most competitive pricing across networks.

Designed as a one-stop solution for creators and collectors, OKX supports NFT minting, primary issuance, secondary trading, and real-time market data—making it ideal for both casual users and advanced developers leveraging the Marketplace API.

NFT Aggregation: Unified Access Across Chains

One of the standout features of the OKX NFT platform is its NFT aggregator, which consolidates order book depth from multiple leading marketplaces. This means developers can query real-time buy and sell orders across platforms without needing separate integrations.

By combining liquidity from OKX NFT, OpenSea, Magic Eden, LooksRare, IMX, and X2Y2, the aggregator ensures maximum exposure for listed assets and optimal pricing for buyers.

Key Benefits of Aggregation:

Supported blockchains include Ethereum, OKTC, BSC, Polygon, IMX, AVAX-C, Solana, Arbitrum One, zkSync Era, Aptos, Optimism, Klaytn, Arbitrum Nova, Base, and Linea—with plans to expand to additional chains in the future.

This wide chain compatibility makes OKX one of the most versatile NFT ecosystems available.

Primary vs. Secondary Marketplaces

OKX distinguishes between two core types of NFT markets: Issuance (Primary) Marketplace and Secondary Marketplace, each serving distinct user needs.

Issuance Marketplace

The Issuance Marketplace is OKX’s exclusive platform for primary NFT offerings. It features handpicked, high-quality projects that launch directly on OKX. Users gain early access to new collections at launch prices—often lower than post-mint market values.

This decentralized offering model empowers creators to distribute their work fairly while giving collectors first-mover advantages.

Secondary Marketplace

The Secondary Marketplace facilitates peer-to-peer trading of existing NFTs. Built for efficiency and low cost, it supports instant trades with high liquidity. Sellers can list across multiple platforms simultaneously—including OKX NFT, OpenSea, LooksRare, and Magic Eden—with minimal effort.

Buyers benefit from competitive pricing powered by aggregated order books and transparent transaction histories.

Contract Architecture: Secure & Scalable Design

Underpinning the marketplace is a robust smart contract infrastructure designed for security, scalability, and interoperability across EVM and non-EVM chains.

EVM-Compatible Features

For Ethereum Virtual Machine (EVM)-based networks, OKX supports advanced functionalities such as:

These features streamline user experience while ensuring fair compensation for artists through automated royalties.

Solana Contract Capabilities

On Solana, the contract system supports:

Despite architectural differences, OKX maintains feature parity where possible to ensure consistent user experiences across ecosystems.

How Contracts Work Together

  1. Users authorize the OKX secondary market via union approve contracts (except for native tokens).
  2. They then interact with the OKX Aggregator contract to place bids or list NFTs.
  3. For cross-marketplace aggregation, Adapter contracts are developed per marketplace (e.g., OpenSea Adapter).
  4. These adapters register with the Market Registry and connect to the main Aggregator contract.

This modular design allows flexible integration with external platforms while maintaining control and transparency within the OKX ecosystem.
