Welcome to @vitalik.eth, co-founder of Ethereum!  

He’s kindly agreed to do an AMA. Reply with your questions. :)

In a future full of embedded wallets, do people have:

1) Primarily a new address for every new app, 
2) Primarily one address across many apps, or
3) A fairly even spectrum?

Today we're at (2). I hope that we move closer to (1), as that would be better for privacy. Sometimes it makes sense for different apps to share wallets, but that should not be the default. We also need to keep improving ZK sends so that the privacy gains from splitting activity become actually real.

Follow up on this - do you see these distinct wallets in each app, or “virtual accounts” that are still managed in a single branded wallet like Metamask?

I.e you log in with Metamask and it generates an address per site, or log in with email/social and generate a wallet per site?

I definitely hope that it's one wallet and it generates an address per site.

Each app having a custom wallet would be a disaster imo.
