Building blockchain applications has historically required either deep specialist expertise or working through complex direct integrations with multiple blockchain networks — a barrier that has limited the rate at which conventional software developers could adopt blockchain technology for legitimate use cases. Tatum was founded in Prague in 2017 to abstract that complexity into a simpler developer experience. Its platform provides unified APIs for building applications across multiple blockchain networks, supporting Ethereum, Bitcoin, Solana, and dozens of other chains through a consistent interface that handles wallet management, transaction signing, smart contract interaction, and the operational infrastructure that production blockchain applications require. The Czech engineering base reflects Central Europe's broader strength in technical infrastructure software, and Tatum has built a developer base across enterprises and crypto-native projects that need blockchain capability without the complexity of direct integration with each network. In the broader blockchain infrastructure landscape, the developer platform model competes with infrastructure providers like Alchemy and Infura on different competitive axes — Tatum's multi-chain unified approach addresses developers who need network breadth rather than depth in a single chain ecosystem. The category remains competitive as enterprise blockchain adoption continues evolving and as the relative importance of different blockchain networks shifts with broader market conditions.
