Very cool.

But would be an L2 address like on ETH. People could ( with an update) import there ETH to keychain and post.

Sure they can post on hive directly but they could use a dapp and the dapp could post for them.

Not perfect but we would have from 1 day to another in theory all eth users on hive ( if they want).

I dont know how much work that would be, but only wallets with public keys without transactions could be maybe doable.

Or import on demand.

I mean i like the solution, but fees on wallets are always something of bad taste and make the hive token itself less valuable.
