POLKASCAN is an open-source multi-chain block explorer and Python tooling project for Substrate-based networks, founded by Emiel Sebastiaan and Arjan Zijderveld. POLKASCAN's Twitter Score is 13 out of 1000 as of October 2026, ranking #74,391 among 493,668 tracked accounts.
POLKASCAN was described by Parity Technologies as the first multi-chain block explorer built for Substrate blockchains. Web3 Foundation previously awarded POLKASCAN a grant to complete a fully functional multi-chain explorer. POLKASCAN also maintained the Python Substrate Interface and SCALE codec library, both widely used across the Polkadot ecosystem.
POLKASCAN has since wound down its primary operations. The Polkascan Foundation legal entity was unwound at the end of 2024, and the block explorer has been marked as inactive in Polkadot's open-source-stack guide. In March 2025, JAMdot Technologies took over stewardship of the Python libraries that POLKASCAN had maintained.
