Multi-network explorer for Polkadot, Kusama, and Substrate chains
Last updated: July 2026
Subscan is the leading block explorer for the Polkadot ecosystem, covering the Polkadot and Kusama relay chains along with the many parachains and standalone Substrate-based networks built on the same framework. Like the ecosystem it serves, Subscan is multi-network, offering a consistent explorer experience across dozens of Substrate chains from one interface. It models Polkadot-specific concepts that generic explorers can't: staking and nominations, on-chain governance (OpenGov referenda and proposals), parachain crowdloans and auctions, cross-consensus messaging (XCM) between chains, and the account/identity system. For DOT and KSM holders staking, nominating validators, or voting in governance, and for developers building on Substrate, Subscan is the essential reference tool, complete with account portfolio views, extrinsic and event decoding, and an API. Browsing is free, with API plans for developers needing programmatic access. The considerations track the ecosystem's complexity: Substrate's extrinsic/event model and Polkadot's governance and staking mechanics have a steep learning curve, the multi-network breadth can be disorienting, and depth varies across smaller parachains. But as the canonical explorer for Polkadot, Kusama, and the wider Substrate world — the tool that ecosystem wallets and dashboards integrate with — Subscan is effectively irreplaceable for anyone active in that ecosystem.
