🦍Account Abstraction Protocol Lead

Pass the invariant fuzz suite to unlock a Soulbound NFT mint in Prüfstand.

Architecture Blueprint

Bundler submits UserOperation array to EntryPoint. EntryPoint executes two-phase lifecycle: validateUserOp (signature, paymaster stake) then executeUserOp.

1. Caller ➔ [Entry Call] ➔ ZehnAccount.sol

2. Execute protocol-defined state transition

3. Verify invariants hold post-transition
