About Tatum

Tatum.io is a pioneering company in the blockchain and Web3 development space, offering an open-source software development kit (SDK) that simplifies the process of building Web3 applications. The company serves developers who are looking to create blockchain-based applications but may lack extensive blockchain experience. Operating in the rapidly growing blockchain market, Tatum.io provides infrastructure and a unified framework for 90 different blockchain protocols, eliminating the need for developers to run nodes or learn to code for individual blockchains. This makes it easier and faster for developers to bring their Web3 applications to market.

Tatum.io's business model revolves around offering its SDK and related tools for free, thereby fostering a community of developers who can contribute to and benefit from its open-source platform. The company generates revenue through premium services, such as advanced features and support, as well as special yearly offers designed to help developers manage market fluctuations.

The company also offers Tatum Academy, a free educational platform aimed at equipping developers with the skills needed to build Web3 applications. This initiative underscores Tatum.io's commitment to making blockchain technology accessible to a broader audience.
