Deployer

op-deployer simplifies the process of deploying the OP Stack. It works similarly to Terraform (opens in a new tab). Like Terraform, you define a declarative config file called an "intent," then run a command to apply the intent to your chain. op-deployer will compare the state of your chain against the intent, and make whatever changes are necessary for them to match. In its current state, it is intended to deploy new standard chains that utilize the Superchain wide contracts.

Installation

There are a couple of ways to install op-deployer:

Option 1: Build from source (Recommended)

To install from source, you will need Go (opens in a new tab), just, and git. After installing all of that, run following:

 
git clone https://github.com/ethereum-optimism/optimism.git # you can skip this if you already have the repo
cd optimism/op-deployer
just build
cp ./bin/op-deployer /usr/local/bin/op-deployer # or any other directory in your $PATH
 
# Verify installation, run this command to verify that you have it installed.
op-deployer --version

Option 2: Download pre-built binary

The recommended way to install op-deployer is to download the latest release from the monorepo's release page (opens in a new tab).

1. Go to https://github.com/ethereum-optimism/optimism/releases (opens in a new tab)
2. Find the latest release that includes op-deployer
3. Under assets, download the binary that matches your operating system:

• op-deployer-linux-amd64 for Linux
• op-deployer-darwin-amd64 or op-deployer-darwin-arm64 for macOS
• op-deployer-windows-amd64.exe for Windows

4. Extract the binary to a location on your system PATH
5. Verify installation, run this command to verify that you have it installed.

op-deployer --version

Deployment usage

The base use case for op-deployer is deploying new OP Chains. This process is broken down into three steps:

init: configure your chain

To get started with op-deployer, create an intent file that defines your desired chain configuration. Use the built-in op-deployer utility to generate this file:

op-deployer init \
  --l1-chain-id <chain ID of your L1> \
  --l2-chain-ids <comma-separated list of chain IDs for your L2s> \
  --workdir .deployer \
  --intent-type <standard|custom|standard-overrides>
 

• Replace <l2-chain-id> with the exact value.
• The --workdir flag specifies the output directory for the generated intent file and related configs. You can name this directory anything you like , .deployer is just an example.

This command will create a directory called .deployer in your current working directory containing the intent file and an empty state.json file. state.json is populated with the results of your deployment, and never needs to be edited directly.

Your intent file will need to be modified to your parameters, but it will initially look something like this:

deploymentStrategy = "live"
configType = "standard-overrides"
l1ChainID = 11155111# The chain ID of Sepolia (L1) you'll be deploying to.
fundDevAccounts = true# Whether or not to fund dev accounts using the test... junk mnemonic on L2.
l1ContractsLocator = "tag://op-contracts/v1.8.0-rc.4"# L1 smart contracts versions
l2ContractsLocator = "tag://op-contracts/v1.7.0-beta.1+l2-contracts"# L2 smart contracts versions# Delete this table if you are using the shared Superchain contracts on the L1# If you are deploying your own SuperchainConfig and ProtocolVersions contracts, fill in these details

Understanding the intent.toml fields

Working with artifacts

The artifacts-locator parameter specifies where the contract deployment artifacts are located. There are several ways to provide artifacts:

Using local files

To use local artifacts (recommended for production or if you're experiencing issues with remote artifacts):

1. Clone the contracts repository:

   git clone https://github.com/ethereum-optimism/optimism.git
       cd optimism
       git checkout v1.8.0-rc.4  # Use the desired version
    

2. Build the contract artifacts:

       cd packages/contracts-bedrock
       just build

3. Use the local path in your command, referencing the artifacts from: <monorepo-root>/packages/contracts-bedrock/forge-artifacts

Using tagged artifacts

For development or testing, you can try using tagged artifacts:

--artifacts-locator tag://op-contracts/v1.8.0-rc.4

If you encounter the error Application failed: failed to parse artifacts URL: unsupported tag, you'll need to use the local files method described above, else If you use an invalid tag, the command will display all valid options.

Contract locator schemes

op-deployer uses contract locators to find contract artifacts to deploy. Locators are just URLs under the hood. The l1ContractsLocator and l2ContractsLocator fields support several schemes for specifying where to find the contract implementations:

• tag:// - References a specific tagged release of the contracts (e.g., tag://op-contracts/v1.8.0-rc.4). In this case, the contracts bytecode will be downloaded from a fixed bytecode bundle on GCS.
• file:// - Points to a directory on local disk containing the artifacts. This is useful for local development, since you can point it at your local monorepo e.g. file://<path-to-repo-root>/packages/contracts-bedrock/forge-artifacts
• http:// or https:// - Points to a target directory containing contract artifacts. The URL should directly reference the directory containing the forge-artifacts directory, in this case, the bytecode will be downloaded from the URL specified.

For example:

# When using tag:// scheme
configType = "standard-overrides"
l1ContractsLocator = "tag://op-contracts/v1.8.0-rc.4"
l2ContractsLocator = "tag://op-contracts/v1.7.0-beta.1+l2-contracts"
 
# When using other schemes (file://, http://, https://)
configType = "custom"  # or "standard-overrides"
l1ContractsLocator = "file:///path/to/local/op-contracts/v1.8.0-rc.4/forge-artifacts"
l2ContractsLocator = "<https://example.com/op-contracts/v1.7.0-beta.1+l2-contracts.tar.gz>"

By default, op-deployer will fill in all other configuration variables with those that match the standard configuration (opens in a new tab). You can override these default settings by adding them to your intent file using the table below:

[globalDeployOverrides]
  l2BlockTime = 1# 1s L2blockTime is also standard, op-deployer defaults to 2s
 

You can also do chain by chain configurations in the chains table.

apply: deploy your chain

Now that you've created your intent file, you can apply it to your chain to deploy the L1 smart contracts:

op-deployer apply --workdir .deployer --l1-rpc-url <rpc-url> --private-key <private key hex>
 

• Replace <rpc-url> with your L1_RPC_URL and <private key> with your private key

This command will deploy the OP Stack to L1. It will deploy all L1 contracts for each L2 specified in the intent file.

Superchain configuration will be set to the Superchain-wide defaults - i.e., your chain will be opted into the Superchain pause (opens in a new tab) and will use the same protocol versions (opens in a new tab) address as other chains on the Superchain. You will need to specify additional arguments depending on what you're trying to do. See below for a reference of each supported CLI arg:

• Deployment targets:

  The --deployment-target flag specifies where to deploy:

  • live: Deploys directly to a live L1 network. Requires -l1-rpc-url and -private-key.
  • genesis: Generates an L1 genesis file for local testing or development.
  • calldata: Produces calldata for multisig wallets, enabling offline deployment.
  • noop: Performs a dry-run without actual deployment, useful for testing configurations.

  Choose the deployment target that best fits your use case.

verify: verify contract source code on block explorers

After deploying your contracts, you can verify them on block explorers like Etherscan:

op-deployer verify \
  --l1-rpc-url <l1 rpc url> \
  --input-file <filepath to input .json file> \
  --etherscan-api-key <your free etherscan api key> \
  --artifacts-locator <file:///path/to/artifacts>
 

Common options:

• -l1-rpc-url: RPC URL for the L1 chain
• -etherscan-api-key: API key for the block explorer (e.g., from Etherscan)
• -artifacts-locator: Path or plugin to locate contract artifacts
• -input-file: Path to a JSON file containing deployment data:
  • Create an input.json file in the same directory.
  • Navigate to your state.json file and locate the implementationsDeployment object.
  • opy everything inside the implementationsDeployment object (without the object name itself) and paste it into your new input.json file.

Example:

op-deployer verify \
  --l1-rpc-url <https://sepolia.infura.io/v3/YOUR_INFURA_KEY> \
  --etherscan-api-key <YOUR_ETHERSCAN_API_KEY> \
  --input-file <file_path_to_input.json | e.g .deployer/input.json> \
  --artifacts-locator <tag://op-contracts/v3.0.0-rc.2>

inspect: generate genesis files and chain information

Inspect the state.json file by navigating to your working directory. With the contracts deployed, generate the genesis and rollup configuration files by running the following commands:

op-deployer inspect genesis --workdir .deployer <l2-chain-id> > .deployer/genesis.json
op-deployer inspect rollup --workdir .deployer <l2-chain-id> > .deployer/rollup.json
 

Now that you have your genesis.json and rollup.json you can spin up a node on your network. You can also use the following inspect subcommands to get additional chain artifacts:

op-deployer inspect l1 --workdir .deployer <l2-chain-id># outputs all L1 contract addresses for an L2 chain
op-deployer inspect deploy-config --workdir .deployer <l2-chain-id># outputs the deploy config for an L2 chain
op-deployer inspect l2-semvers --workdir .deployer <l2-chain-id># outputs the semvers for all L2 chains
 

Bootstrap usage

op-deployer provides a set of bootstrap commands specifically designed for initializing a new superchain target on an L1 network. These commands are essential when you're setting up a completely new superchain target environment rather than deploying a new chain on an existing superchain.

Bootstrap process overview

When bootstrapping a new superchain target, you typically need to follow this process:

1. Deploy proxy admin (bootstrap proxy): Sets up the ERC-1967 proxy for the superchain management contracts.
2. Deploy Superchain configuration (bootstrap superchain): Creates the foundational superchain configuration contracts.
3. Deploy implementations (bootstrap implementations): Deploys the implementation contracts needed for the dispute game.
4. Deploy validator (bootstrap validator): Deploys the StandardValidator for the superchain.

Bootstrap proxy

The bootstrap proxy command deploys a new ERC-1967 proxy admin, which is required for upgradeability of the superchain contracts.

Command usage

op-deployer bootstrap proxy \
  --l1-rpc-url <L1_RPC_ENDPOINT> \
  --private-key <YOUR_PRIVATE_KEY> \
  --artifacts-locator <file:///path/to/artifacts> \
  --proxy-owner <PROXY_ADMIN_OWNER_ADDRESS> \
  --outfile proxy-output.json
 

Parameters

Example:

op-deployer bootstrap proxy \
  --l1-rpc-url <L1_RPC_ENDPOINT> \
  --private-key <YOUR_PRIVATE_KEY> \
  --artifacts-locator <file:///path/to/artifacts> \
  --proxy-owner <PROXY_ADMIN_OWNER_ADDRESS> \
  --outfile proxy-output.json
 

Output

The command outputs a JSON file containing the deployed proxy contract address:

{
  "Proxy": "0x123...abc"
}
 

Bootstrap superchain

The bootstrap superchain command initializes the core SuperchainConfig and ProtocolVersions contracts. These contracts maintain global configuration parameters (including pause functionality) and protocol version requirements across all chains in the superchain. This step is typically performed once when establishing a new superchain on an L1 network, with the deployed addresses needed for subsequent bootstrap commands.

Command usage

op-deployer bootstrap superchain \
  --l1-rpc-url <L1_RPC_ENDPOINT> \
  --private-key <PRIVATE_KEY> \
  --artifacts-locator <ARTIFACTS_LOCATOR> \
  --superchain-proxy-admin-owner <ADMIN_OWNER_ADDRESS> \
  --protocol-versions-owner <VERSIONS_OWNER_ADDRESS> \
  --guardian <GUARDIAN_ADDRESS> \
  --paused <false> \
  --outfile superchain-output.json
 

Parameters

Example:

op-deployer bootstrap superchain \
  --l1-rpc-url <L1_RPC_ENDPOINT> \
  --private-key <YOUR_PRIVATE_KEY> \
  --artifacts-locator <file:///path/to/artifacts> \
  --superchain-proxy-admin-owner <ADMIN_OWNER_ADDRESS> \
  --protocol-versions-owner <VERSIONS_OWNER_ADDRESS> \
  --guardian <GUARDIAN_ADDRESS> \
  --paused false \
  --outfile superchain-output.json
 

Output

The command outputs a JSON file containing the deployed superchain contract addresses:

{
  "SuperchainConfig": "0x123...abc",
  "ProtocolVersions": "0x456...def"
}
 

Bootstrap implementations

The bootstrap implementations command deploys essential OP Stack infrastructure contracts. Chain operators use this command when spinning up a brand new superchain target, not when adding a chain to an existing superchain.

Command usage

op-deployer bootstrap implementations \
  --l1-rpc-url <L1_RPC_ENDPOINT> \
  --private-key <PRIVATE_KEY> \
  --artifacts-locator <ARTIFACTS_LOCATOR> \
  --outfile ./.deployer/bootstrap_implementations.json \
  --mips-version <1 or 2, for MIPS32 or MIPS64> \
  --protocol-versions-proxy <address output from bootstrap superchain> \
  --superchain-config-proxy <address output from bootstrap superchain> \
  --upgrade-controller <superchain-proxy-admin-owner used in bootstrap superchain>

Parameters

Understanding MIPS version

The mips-version parameter determines which version of the Cannon MIPS VM to use for fault proofs:

• MIPS Version 1 (MIPS32): The original implementation based on the 32-bit MIPS architecture. Suitable for most legacy or existing deployments.
• MIPS Version 2 (MIPS64): An enhanced implementation based on the 64-bit MIPS architecture, offering improved performance and efficiency. Generally preferred for new deployments.

For most new deployments, MIPS Version 2 (MIPS64) is recommended unless you have specific compatibility requirements.

Example:

op-deployer bootstrap implementations \
  --artifacts-locator file:///path/to/artifacts \
  --l1-rpc-url L1_RPC_ENDPOINT \
  --outfile ./.deployer/bootstrap_implementations.json \
  --mips-version 1 \
  --private-key YOUR_PRIVATE_KEY \
  --protocol-versions-proxy <address output from bootstrap superchain> \
  --superchain-config-proxy <address output from bootstrap superchain> \
  --upgrade-controller <superchain-proxy-admin-owner used in bootstrap superchain>
 

Output

The command outputs a JSON file containing the deployed implementation contract addresses:
