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.

With full support for ARB and OP, Tatum gives you the power to build fast, data-rich applications on Ethereumβs most adopted L2s β without worrying about the backend complexity.
Weβre expanding our Bitcoin support with the addition of Bitcoin Signet β the latest Bitcoin test network designed for stability and control. Unlike traditional testnets, Signet uses a custom signature-based validation, allowing block production to be centrally coordinated. This ensures more reliable block times, reduced spam, and easier faucet funding, making it ideal for testing wallets, applications, and integrations without mainnet risk.
