OP Stack Deployer is a tool that simplifies setting up and deploying an OP Stack chain on the Ethereum Sepolia testnet. This guide will walk you through the steps required to spin up your OP Stack chain and perform tests or customize it for your specific needs.

This project is based on the OP Stack Getting Started doc.

Before getting started, ensure that you have the following software installed: Git, Go, Node, Pnpm, Foundry, Make, jq, and direnv.

First of all clone the op-stack-deployer repository

git clone https://github.com/Aymen-Tirchi/op-stack-deployer.git && cd op-stack-deployer

And then follow these steps:

1. Build the Optimism Monorepo

go run cmd/1_build_optimism/main.go

This script will automatically clone the Optimism Monorepo, install the required modules, build the necessary packages, and generate the Optimism Monorepo and packages successfully.

2. Build op-geth

go run cmd/2_build_op-geth/main.go

This script will automatically clone the op-geth repo, build the necessary packages, and generate the op-geth repo and packages successfully.

3. Generate some keys

go run cmd/3_generate_keys/main.go

This script will generate the keys of each role and store them in a text file named keys.txt in the root directory of the project. The keys.txt file will contain the addresses and private keys for the Admin, Proposer, Batcher, and Sequencer accounts.

4. Configure your network

• Before you run the script go to this path optimism/packages/contracts-bedrock you will find .envrc., set the ETH_RPC_URL that you are using, and replace the PRIVATE_KEY with the actual private key of the Admin which is in the keys.txt, and the DEPLOYMENT_CONTEXT stays the same which is getting-started.

go run cmd/4_configure_network/main.go

• This script will automatically configure your network based on the generated keys and the provided L1 node RPC URL. It will configure getting-started.json in the optimism/packages/contracts-bedrock/deploy-config directory, which contains all the required parameters for your network setup.

5. Deploy the L1 contracts

• Before running the deploy_L1_contracts.go script, ensure that you have funded your Admin address with some Sepolia test ETH (at least 0.5 ETH). Having sufficient test ETH will cover the gas costs and ensure the successful deployment of the L1 contracts.

• Now you can run the script :

go run cmd/5_deploy_L1_contracts/main.go

The script will start deploying all the L1 smart contracts. During the deployment process, you may see various transaction logs and updates. Once the deployment is successful, you will receive a confirmation message.

6. Generate the L2 config files

sudo go run cmd/6_L2_config/main.go

This script will automatically create the necessary L2 configuration files genesis.json, rollup.json, and jwt.txt. These files are crucial for the configuration and secure communication between the op-node and op-geth.

7. Initialize op-geth

go run cmd/7_Initialize_op-geth/main.go

This script will create a data directory and initialize the op-geth with the genesis.json we generated in the previous script.

8. Run the node software

before running anything make sure you fund your batcher and proposer addresses with at least 0.5 Sepolia test ETH, to ensure that it can continue operating without running out of ETH for gas.

• Run op-geth

go run cmd/8_run_op-geth/main.go

This script will run the op-geth node.

• Run op-node

go run cmd/9_run_op-node/main.go 

This script will set up system variables and run op-node.

• Run op-batcher

go run cmd/10_run_op-batcher/main.go 

This script will set up system variables and run op-batcher.

might have warning messages similar to:

WARN [03-21|14:13:55.248] Error calculating L2 block range         err="failed to get sync status: Post \"http://localhost:8547\": context deadline exceeded"

This means that op-node is not yet synchronized up to the present time. Just wait until it is.

• Run op-proposer

go run cmd/11_run_op-proposer/main.go 

This script will set up system variables and run the op-proposer.

9. Get some ETH on your Rollup

To get the address of your Rollup run the following command

go run cmd/12_get_rollup_address/main.go 

and now you can fund your rollup address with some ETH. It may take up to 5 minutes for that ETH to appear in your wallet on L2.

Congratulations, You have a complete OP Stack-based EVM Rollup.

10. Use your Rollup

To see your rollup in action, you can use the optimism-tutorial.
