Rivius Wallet [Testnet] от Rivius Network

Manage your Rivius accounts outside of dapps. Injects the accounts and allows signing transactions for a specific account.
Manage your Rivius accounts outside of applications built on Substrate (https://github.com/paritytech/substrate), Rivius (https://rivius.network/). 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. 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://extension.rivius.network.
