Contract Deployer Allowlist

Enable and understand the Contract Deployer AllowList precompile (who can deploy contracts).

Overview

The Contract Deployer AllowList precompile controls who can deploy smart contracts on your Avalanche L1. If an address is not allowed, contract deployment transactions will revert.

This is commonly used to:

  • Prevent malicious or unreviewed contract deployments
  • Enforce “only approved deployers” policies (CI/CD wallets, audited teams)
  • Run curated ecosystems with stronger guarantees

Quick reference

From the docs:

  • Precompile address: 0x0200000000000000000000000000000000000000
  • Genesis config key: contractDeployerAllowListConfig
  • Permission model: uses the AllowList interface

Docs: /docs/avalanche-l1s/precompiles/deployer-allowlist

Genesis activation

To enable it from genesis, include a config block like:

{
  "config": {
    "contractDeployerAllowListConfig": {
      "blockTimestamp": 0,
      "adminAddresses": ["0x...yourAdminAddress"]
    }
  }
}

The adminAddresses become AllowList Admins for this precompile.

Summary

Key points:

  • Contract Deployer AllowList gates contract deployment at the network level.
  • It’s configured at genesis via contractDeployerAllowListConfig.
  • It reuses the AllowList permission model (Admin/Manager/Enabled).
