Testing precompile activation

Objectives

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

• Verify the allowlist precompiles are active again (the tools no longer show “not available”).
• Confirm your wallet is an admin for both allowlists (per your upgrade.json config).
• Test basic functionality: sending a transaction and deploying a contract.

Prerequisites

Before starting this exercise, ensure you have:

• Restarted your Docker validator after appending the re-activation entries to upgrade.json.
• Waited long enough for the activation timestamps to pass (a block after each timestamp must be accepted).
• Core Wallet connected to your custom L1.

Instructions

Step 1: Confirm the precompiles are active (UI should be available)

Open both tools while connected to your custom L1:

Expected Result: you should see the full allowlist UI (not the “not available / not activated” state).

Step 2: Confirm your wallet is an Admin

In each tool:

1. Select readAllowList
2. Paste your wallet address
3. Execute/read

Expected Result: your role should reflect Admin (because you added your address to adminAddresses in upgrade.json for both precompiles).

Step 3: Test you can transact and deploy again

Transaction test (Core Wallet):

• In Core Wallet (connected to your custom L1), attempt to send a small amount of native token to another address.
• The transaction should succeed once the Transaction Allowlist is active and your address is authorized.

Deployment test (Builder Console):

Click “Deploy ICMDemo” and confirm the transaction in Core Wallet.

If sending or deploying still fails, use the allowlist tools to explicitly setEnabled for your wallet address (or confirm your admin role is correctly set and the activation timestamp has passed).

Expected Output

• The allowlist tools render normally (no “not available” state).
• Your wallet reads as Admin in both tools.
• Sending a transaction and deploying a contract succeed.

Verification

To verify you've completed this exercise successfully:

1. TransactionAllowlist and DeployerAllowlist load normally on your L1.
2. readAllowList reports your wallet as Admin for both.
3. You can send a transaction and deploy a contract again.

Next Steps

Now that you can toggle these precompiles off and on via upgrades, you can apply the same upgrade pattern to other Subnet-EVM precompiles (fee manager, native minter, etc.) using the same upgrade.json mechanism.
