OP Mainnet is a Layer 2 platform for Ethereum.

OP Mainnet is, in a nutshell, an application inside of Ethereum that executes transactions more efficiently than Ethereum itself. It's based on the concept of the Optimistic Rollup, a construction that allows us to "optimistically" publish transaction results without actually executing those transactions on Ethereum (most of the time). OP Mainnet makes transactions cheaper, faster, and smarter.

yarn dev

Then navigate to http://localhost:8080. If that link doesn't work, double check the output of yarn dev. You might already be serving something on port 8080 and the site may be on port 8081.

yarn build

You probably don't need to run this command, but now you know.
