At SonarX, our mission is to deliver high-quality, reliable blockchain data that empowers analysts, developers, and institutions to build with confidence. Today, we’re excited to announce the release of our NFT Sales dataset, now fully modeled and available for both Ethereum and Base.

What Are NFT Sales?

NFT sales represent the exchange of a non-fungible token on a marketplace. Accurately capturing these transactions across fragmented marketplaces and protocol versions is critical to understanding market activity, pricing dynamics, liquidity, and participant behavior.

Our new dataset aggregates NFT sales into a single, standardized table per chain, making it easier than ever to query, analyze, and build data-driven products without worrying about marketplace-specific complexities.

Extensive Marketplace Coverage

• Magic Eden
• NFTX
• OpenSea
  • Wyvern V1, Wyvern V2
  • Seaport 1.1, 1.4, 1.5, 1.6
• Rarible (V1, V2)
• Sudoswap (V1, V2)
• X2Y2

Base

On Base, we support the following platforms:

• 0x
• Element
• OpenSea
  • Seaport 1.5, Seaport 1.6

Unified, Analytics-Ready Schema

Each chain’s dataset consolidates NFT sales into a single table with rich transactional and marketplace metadata. We include important data about the transaction in which the NFT sale took place, such as the block number, transaction hash, and log index. We also have information about the sale, such as the token ID, type, and address; the buyer and seller; the transaction from and to; and the pricing/fee information. Furthermore, we include the name of the aggregator contract if one is utilized in the sale.

This structure provides a complete view of each sale — from execution to settlement — allowing users to perform deep analyses on pricing, royalties, platform economics, and trading behavior.

Built for Serious Data Work

By normalizing data across marketplaces and protocol versions, SonarX eliminates the heavy lifting typically required to reconcile NFT activity. Whether you’re:

• Analyzing marketplace competition
• Tracking creator royalties
• Building valuation models
• Researching trader behavior
• Powering dashboards

Our NFT Sales dataset provides a reliable foundation.

Continuing to Expand Coverage

This release represents another step toward SonarX’s goal of delivering best-in-class blockchain datasets. We will continue expanding marketplace coverage, improving attribution, and refining our models to ensure you have the most complete view of on-chain activity possible.

NFT Sales data for Ethereum and Base is available now. If you’re interested in learning more or integrating this dataset into your workflows, reach out to the SonarX team.
