Test for Error

Objectives

By the end of this exercise, you will be able to:

Verify you can no longer submit transactions after removing your transactor permissions
Verify you can no longer deploy contracts after removing your deployer permissions
Recognize the failure modes users will see in wallets and dApps

Before starting this exercise, ensure you have:

Completed the previous lesson and removed your wallet from Admin on both allowlist precompiles
Still connected to your L1 in Core Wallet

In your Core Wallet browser extension:

You should see a failure/revert because the Transaction AllowList blocks your address from submitting transactions.

Use the ICM demo deploy tool (any deployment attempt works — we’re just testing deploy restrictions):

Builder Console

Checking requirements...

When you try to deploy, the transaction should fail because the Contract Deployer AllowList blocks your address from deploying contracts.

Note the exact error messages you see in:

These are the same user-facing symptoms you must plan for when operating a restricted-access L1.

You should see:

To verify you've completed this exercise successfully:

You likely still have Enabled access on the Transaction AllowList (or you didn’t enable it at genesis).
Verify the precompile is enabled and your role is None.

Next we’ll cover how to safely recover from mistakes like this using network upgrades (enable/disable + role recovery).
