Primitive
Wallet infrastructure is hard to sell as infrastructure. It becomes easier to understand when the account abstraction is part of a game loop you can just tap.

USDC action without a wallet popup — account abstraction hidden inside a game loop

Playable demo rather than a slide about Sub Accounts
Proof, up close
What the screenshots actually prove.
What went right
- The game metaphor makes wallet primitives less intimidating.
- Zero-popup USDC is a real UX proof, not a mockup.
- The artifact is more memorable than a Sub Accounts explainer.
What went wrong
- Playful infra can be dismissed as a toy if the real primitive is not explicit.
- Games need retention loops; demos only need clarity.
- The onchain action needs to stay visible enough to read as proof.
