🔎 OP Scan

OP Scan is a transaction explorer tailored specifically for the OP Stack and the Superchain vision. It's purpose built to be lightweight, so that anyone can run it locally next to their OP Stack nodes, when working on a new rollup.

🦄 How OP Scan Differs from Other Explorers

  1. Lightweight: The code and dependencies are designed to be minimalistic. This ensures minimal resource consumption, allowing anyone to run it locally alongside an OP Stack node when working on a rollup.
  2. OP Stack Native: This explorer is purpose-built for the OP Stack. It ensures 100% compatibility with rollups in Optimism’s Superchain.
  3. Scalable: Despite its lightweight design, the explorer is built to handle any scale.
  4. Open Source: All code is open source from day one. This alignment with the community allows anyone to contribute or fork the repository to meet their specific needs.

⚙️ Installation

The app requires the following dependencies:

NodeJS >= 20
pnpm >= 9

Run the Explorer Locally

Clone this repository:

git clone git@github.com:walnuthq/op-scan

Install the dependencies:

pnpm install

You will need to create a .env.local file in the root of your repository and populate it with NEXT_PUBLIC_L1_RPC_URL and NEXT_PUBLIC_L2_RPC_URL.

NEXT_PUBLIC_L1_RPC_URL="https://eth-mainnet.g.alchemy.com/v2/..."
NEXT_PUBLIC_L2_RPC_URL="https://opt-mainnet.g.alchemy.com/v2/..."

You can get free node rpcs url by signing up to services such as Alchemy or Infura.

If you're running the indexer, you will also need to setup a websocket connection to the L2 chain:

Start up the app and see it running at http://localhost:3000

pnpm dev

Run the Indexer

To run the indexer, you first need to setup your DATABASE_URL in .env.local as well as websocket connections to your L1/L2 chains (once again you can get them from a 3rd-party provider):

DATABASE_URL="file:dev.db"
L1_RPC_WSS="wss://eth-mainnet.g.alchemy.com/v2/..."
L2_RPC_WSS="wss://opt-mainnet.g.alchemy.com/v2/..."

Then you can sync your local database with the Prisma schema:

pnpm prisma:db:push

We use Bun to run the indexer as a long-running script so make sure it is installed globally on your system. Now you will be able to start indexing the blockchain by running the op-indexer command:

pnpm op-indexer

You should start seeing blocks getting indexed in your terminal and you can explore the state of your local database using Prisma studio:

pnpm prisma:studio

If you need to change the Prisma schema at some point, make sure to regenerate the Prisma client and push to your local database:

pnpm prisma:generate
pnpm prisma:db:push
