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

Instructions

Step 1: Attempt a normal transaction (should fail)

In your Core Wallet browser extension:

1. Stay on your L1 network
2. Try to send a small amount of the native token to any address you control
3. Confirm the transaction

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

Step 2: Attempt a contract deployment (should fail)

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.

Expected Output

You should see:

• A failed value transfer transaction (blocked by Transaction AllowList)
• A failed contract deployment (blocked by Contract Deployer AllowList)

Next Steps

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