Question to account abstraction OGs -

when I open a smart wallet with some vendor (let's say Coinbase), the wallet doesn't hold my pk

And I control the onchain smart wallet

So can I just switch vendors on the front end? the FE initates the tx and the wallet just signs with passkey and send it to an RPC

Theoretically yes. In the case of Coinbase you’ll need a new passkey signer considering the passkey is tied to the keys.coinbase.com domain

Yes it’s a passkey technical feature/limitation introduced by Apple and Google. I.e it’s a part of the overall architecture

tnx

is there any technical reason for the passkey to be associated with the domain? (except of business reasons)
