What is Substrate Connect?
A fast, secure, and decentralized way to interact with Polkadot, Kusama, and their parachains right in the browser, Substrate Connect helps you build better end-user experiences for Web3 apps.
Light Client Based
Light clients allow you to interact with a blockchain in a less resource-intensive way than running a full node. Because they can quickly sync with a blockchain and run locally in browsers and on mobile and IoT devices, light clients are set to power the future of decentralized applications.
Running a full node requires a lot of knowledge, effort, and resources, and connecting to remote third-party nodes can be insecure and unreliable. Substrate Connect is the most convenient way to securely and trustlessly connect your app to any Substrate-based chain.

The Browser Extension
Substrate Connect can run in the browser with each tab running a single light client, but running it as a browser extension will provide a smoother, faster experience. When run as a browser extension, multiple light clients can run simultaneously and can continuously sync as long as the browser stays open. It works on all major browsers and does not require a TLS certificate for connecting to nodes.
Scalable sharded chain and the first protocol that provides a secure environment for cross-chain composability.
A network built as a risk-taking, fast-moving ‘canary in the coal mine’ for its cousin Polkadot.
Testing environment for Polkadot and Kusama deployments and processes.
Testnet designed for parachains and related technologies: Cumulus and HRMP.
