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?

- solidity engineer 
- decentralisation and privacy maxi
- kitesurfer

In this context:
- wallets are the software
- addresses are the account model

It’s too confusing if the two are conflated, even if consumers don’t see the difference.

Do you on purpose mix wallets and addresses here?
Because having an embedded wallet for every dapp or having a single wallet that produces different addresses per app is a diffrent approach (aka actually how worldcoin wants to provide pseudonymity)

In world (1), is the idea that each app operates across chains?

If not, what's your preferred fix for unambious addressing? (Solving the issue that eg friendtech recently ran into, where people sent assets to their friendtech address on mainnet.)

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.
