Tatum supports the entire Polkadot Ecosystem (Polkadot, Polkadot Asset Hub, Kusama, and Kusama Asset Hub), enabling developers to build scalable, interoperable, and production-ready Web3 applications.

The Polkadot ecosystem is a scalable, interoperable blockchain network designed to connect multiple specialized blockchains called parachains under one unified protocol. Built with Substrate and secured by a shared relay chain, Polkadot enables seamless cross-chain communication, flexible governance, and high throughput for decentralized applications. Its ecosystem includes the main Polkadot network for production-grade deployments, Kusama as a fast-moving experimental network, and Asset Hubs for efficient issuance and management of fungible and non-fungible tokens across chains, empowering developers to build next-generation Web3 applications with security, speed, and interoperability at scale.
