 <p>One point worth being exact about: that on-chain paymaster does not read KUMPLY. It is a <code>VerifyingSingletonPaymaster</code> (source verified on Routescan), and its bytecode contains neither our AttestationStore address nor the selectors for <code>verify()</code> or <code>attestations()</code>. The KUMPLY check happens in the service. The chain only confirms the service's approval.</p>
