Manual testing steps

1. Go localhost:8000
2. Make sure your account is not a smart account
3. Grant a new permission
4. Permission page should show a warning that your account will be upgraded
5. After clicking grant first a transaction for upgrading the account should show

Note

Implements smart account upgrade check/trigger during permission approval and surfaces a UI warning when an account will be upgraded.

• Core:
  • AccountController: Add getAccountUpgradeStatus (calls wallet_getAccountUpgradeStatus and verifies upgradedAddress vs contracts.eip7702StatelessDeleGatorImpl) and upgradeAccount (calls wallet_upgradeAccount, returns transactionHash).
  • PermissionRequestLifecycleOrchestrator: Before resolving, re-check upgrade status and call upgradeAccount if not upgraded.
• UI:
  • PermissionHandler: Fetch upgrade status for selected account and pass isAccountUpgraded to content.
  • PermissionHandlerContent: Display warning text when isAccountUpgraded is false; minor token balance prop handling.
• Chain Metadata:
  • Add contracts.eip7702StatelessDeleGatorImpl address to getChainMetadata.
• Tests:
  • Add/extend tests for account upgrade status, upgrade flow, orchestrator integration, and UI rendering of the upgrade warning.

Looks good! I think it’d be better to update the docs to include this new feature.
