Substrate Connect Extension Firefox

Substrate Connect Extension

Browser extension that keeps the latest state of well known substrate-based chains' specs and bootnodes (Polkadot, Kusama, Rococo, Westend) synced across tabs - using Substrate Connect and Smoldot light client;

Features & Capabilities

A Browser Extension using Substrate Connect and Smoldot light client node modules. This extension, upon browser initiation updates and synchronizes in the well known substrate chain specs (Polkadot, Kusama, Rococo, Westend), keeping them to the latest state inside the extension, for faster chain sync. When a dApp that supports Substrate Connect (e.g. polkadotJS apps) starts in a browser's tab, then it receives the latest specs from the Extension instead of wrap-synching from the last imported inside the dApp; At the same time, the dApp will appear inside the Extension as "connected" - meaning that it is using the Extension's bootnodes and specs;

Is Substrate Connect Extension Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Substrate Connect Extension requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
