I wish this project will be useful. A rather interesting website, arguable job, flawless website!
Thank you!!
No installations and no downloads but somewhere the coins need to be stored. Only in web wallets then?
The website is creating for you automatically an wallet. But you can create others by yourself. The wallets are stored using indexeDB in your browser and you have the option to download them for cold storage.
So this is a testnet, right? The coins don't actually count?
Nope, is the main net.
