The Go-To Blockchain Development Platform - Tatum | WarmIndex

Tatum is the go-to blockchain development platform that simplifies building Web3 apps with unified APIs and infrastructure across over 130 blockchains.

🚀 Overview

Tatum is a comprehensive platform designed to make blockchain development fast and accessible by abstracting the complexities of multiple blockchains into a single unified API framework. It provides reliable RPC nodes, data APIs, price feeds, notifications, and more, allowing developers to build, test, and deploy Web3 applications without managing individual chain infrastructure.

The project solves the problem of blockchain fragmentation, where developers face steep learning curves, inconsistent APIs, and scalability issues across different networks. It's built for developers, startups, and teams creating dApps, wallets, DeFi protocols, NFTs, and payments. Tatum was created to accelerate Web3 innovation by enabling quick prototyping and production scaling, as founded by Jiri Kobelka and Samuel Šramko to empower builders with reliable tools.
