Who is behind it
Randy Wasinger founded CryptoSlam in 2018 and is its chief executive. He also founded Ethoswarm, an infrastructure project for persistent AI agents and on-chain interactions. CryptoSlam is headquartered in Overland Park, Kansas. On January 5, 2022, it raised a $9 million seed round backed by Animoca Brands, Mark Cuban, KCRise Fund, Sound Ventures, and angel investors. In February 2026, Ethoswarm partnered with Animoca Brands to launch Animoca Minds.
How the data works
CryptoSlam aggregates NFT activity from multiple networks and presents it through collection rankings, sales data, price history, and rarity metrics. Covered networks include Ethereum, Solana, Flow, WAX, Polygon, and Ronin, within a wider set of more than 15 blockchains. Its developer API provides real-time NFT metrics, sales volumes, and pricing history. The platform also offers dashboards for monitoring market and collection activity.
Fees and availability
Platform access uses a freemium model. The API is available to developers. CryptoSlam is available globally through its web platform and API.
Track record and limitations
The project began in 2018 as a tool for monitoring an Ethereum NFT game. Its stated processing volume is more than 50 million NFT transfers daily, and its coverage has expanded to more than 15 blockchains. Delays, collection attribution errors, wash trading, and changing marketplace activity can affect rankings and sales metrics.
