Introduction

Overview

In the previous section you disabled the Transaction AllowList and Contract Deployer AllowList precompiles via a network upgrade. Now you’ll do the same process in reverse: append new upgrade entries that re-enable both precompiles.

Because disabling clears precompile storage, re-enabling is effectively a fresh initialization. For these allowlist precompiles, that means you must set initial adminAddresses so you can manage roles after activation.

Key Concepts

The rules from the official guide still apply:

• upgrade.json lives at {chain-config-dir}/{blockchainID}/upgrade.json next to config.json.
• precompileUpgrades must be treated as append-only once upgrades activate.
• blockTimestamp must be in the future and upgrades must be in increasing order.
• You must include your wallet address in adminAddresses for both precompiles.
