Blockdaemon vs. BlockSpan

Trusted by 400+ institutions, we support over $110B in digital assets through secure blockchain infrastructure—spanning nodes, APIs, staking services, and MPC wallet technology. Since 2017, our globally distributed systems have delivered enterprise-grade scalability, security, and compliance for the world’s leading financial and crypto platforms.

BlockSpan is an all-encompassing NFT API platform designed specifically for software companies involved in blockchain projects. By aggregating data from a variety of blockchain networks, we provide an API layer that enables NFT developers to retrieve real-time updates on token values, ownership information, and metadata, including cached images. Switching between different blockchains or chains is a seamless experience, removing the need for tedious block log scraping; instead, developers can easily utilize a straightforward REST API integration. Our offerings extend beyond just transaction data, furnishing insights into pricing, up-to-date ownership, and detailed metadata. We currently support networks such as Ethereum, Polygon, Arbitrum, and Optimism, with intentions to broaden our services in the near future. Additionally, we offer comprehensive documentation for each endpoint, supplemented by an interactive API console that enhances user experience. Furthermore, our NFT API not only provides detailed token metadata but also includes cached image URLs, which greatly minimizes the requirement for extra API and IPFS calls to collect that data, thus optimizing the development workflow for our users. This focus on efficiency and user-friendliness is what sets BlockSpan apart in the NFT landscape.
