Hey my name is joohhnnn. Here is my update on EPF4 Week 8.

Week 8 Project Progress Report

Work Completed This Week

1. Addressing the Lingering Issue - Issue 6450

   This week, I continued to tackle the lingering issue, specifically the Issue 6450 in the Ethereum Optimism project. After a deep dive, I pinpointed the issues to the following aspects:

   • Environment Setup: I managed to run the bundler smoothly in my fresh Ubuntu 22.04 setup. Ensure you initiate the devnet correctly. I recommend installing geth by executing make install-geth in the optimism mono.

   • Successful Launch: Following the steps mentioned, I successfully launched the bundler on port 3000 and ensured it was bound to port 9545.

   • Removing ChainID Validation: To tailor to a specific network setting, I removed the ChainID validation found in ./bundler/packages/bundler/deploy/2-deploy-entrypoint.ts.

   • Port Adjustment: I altered the port number to 9545 in both ./bundler/packages/bundler/hardhat.config.ts and ./bundler/packages/bundler/localconfig/bundler.config.json.

   • Shell Script Update: I revised the ./optimism/ops-bedrock/entrypoint-l2.sh script to accommodate the new configurations and environmental variables.

   • Funds Deployment: Utilizing port 9545, I transferred 1 ETH to the address 0x3fab184622dc19b6109349b94811493bf2a45362.

2. Developing an Auto-Configuration Middleware

   Stemming from the issue mentioned above, I crafted an auto-configuration middleware to streamline the configuration process and mitigate potential issues in the future.

3. Exploring the Underlying Code of Optimism

   I initiated a journey into the underlying code of Optimism, getting a preliminary understanding of the directory structure and some non-core parts of the code, such as op-bindings and op-bootnode.

Plans for Next Week

• Delve deeper into the core sections of the Optimism underlying code.
• Prepare to share my experiences and solutions from addressing Issue 6450 with the community.
