Waves Keeper is a browser extension that allows securely interact with Waves-enabled web services. It is currently available in four browsers: Google Chrome (also works with Brave and Yandex.Browser), Firefox, Opera and Microsoft Edge.
We use it because it allows you to hold your keys securely while interacting safely with third-party web resources. You do not need to share your passwords, keys or seed phrases with third parties. What it means is that your assets are always available in your wallet, which you own, control and store privately.
