Substrate Connect Extension

Browser extension to manage substrate-based blockchain light clients

Install Compare

The Substrate Connect Extension is a powerful browser extension designed to streamline interaction with substrate-based blockchain networks. Utilizing Substrate Connect and Smoldot light client node modules, it keeps popular substrate chains like Polkadot, Kusama, Rococo, and Westend up-to-date for rapid synchronization.

By updating chain specifications upon browser launch, the extension enables decentralized applications (dApps) supporting Substrate Connect — such as PolkadotJS apps — to fetch the latest specs directly from it. This eliminates redundant syncing within each dApp, providing smoother and faster blockchain connectivity. Additionally, the extension tracks connected dApps using its bootnodes and chain specs, enhancing user experience and network efficiency.
