Looking for wallet-as-a-service (embedded wallet) providers. So far got Sequence, Coinbase, Magic, Circle. Which big players am I missing?

Also ideally looking for a solution that uses or will use account abstraction.

gm ser

are you still looking for this? We have built a wallet-as-a-service solution for Account Abstraction/Smart contract wallets.

Thanks for the ping. Could you share a link to what you built then I'll have a look!

Sure this doc has more details and a clickable figma prototype
