This extension injects the accounts and allows signing of messages and transactions for a specific account, without making the account secrets available to the calling app.
This allows you to manage your accounts, without storing it is the browser site-specific localStorage, for use on applications such as https://polkadot.js.org/apps/. It does not allow for full wallet capability, but rather is laser focussed on only managing your accounts and providing signing capabilities to applications requesting access. As such, its prime purpose is managing the accounts and injecting them as per the standard extension interfaces, as described in https://github.com/polkadot-js/extension#api-interface.
It allows you to -
- Add accounts, storing the account secrets in your extension storage
- Allow application access to the signing capabilities of these accounts (you can accept/reject requests)
- Allows you to sign transactions for Substrate, Polkadot and Kusama networks
- In all of this no secretes leave the extension, only the signature is ever provided
