-[![codecov](https://codecov.io/gh/ethereum-optimism/optimism/branch/master/graph/badge.svg?token=0VTG7PG7YR&flag=batch-submitter)](https://codecov.io/gh/ethereum-optimism/optimism)
-# Batch Submitter
-
-Contains an executable batch submitter service which watches L1 and a local L2 node and submits batches to the
-`CanonicalTransactionChain` & `StateCommitmentChain` based on its local information.
-
-## Configuration
-All configuration is done via environment variables. See all variables at [.env.example](.env.example); copy into a `.env` file before running.
-
-## Building & Running
-1. Make sure dependencies are installed just run `yarn` in the base directory
-2. Build `yarn build`
-3. Run `yarn start`
-
-## Controlling log output verbosity
-Before running, set the `DEBUG` environment variable to specify the verbosity level. It must be made up of comma-separated values of patterns to match in debug logs. Here's a few common options:
-* `debug*` - Will match all debug statements -- very verbose
-* `info*` - Will match all info statements -- less verbose, useful in most cases
-* `warn*` - Will match all warnings -- recommended at a minimum
-* `error*` - Will match all errors -- would not omit this
-
-Examples:
-* Everything but debug: `export DEBUG=info*,error*,warn*`
-* Most verbose: `export DEBUG=info*,error*,warn*,debug*`
-
-## Testing & linting
-
-### Local
-
-- Run unit tests with `yarn test`
-- See lint errors with `yarn lint`; auto-fix with `yarn lint --fix`
-
-### Submission
-
-You may test a submission locally against a local Hardhat fork.
-
-1. Follow the instructions [here](https://github.com/ethereum-optimism/hardhat) to run a Hardhat node.
-2. Change the Batch Submitter `.env` field `L1_NODE_WEB3_URL` to the local Hardhat url. Depending on which network you are using, update `ADDRESS_MANAGER_ADDRESS` according to the [Regenesis repo](https://github.com/ethereum-optimism/regenesis).
-3. Also check `L2_NODE_WEB3_URL` is correctly set and has transactions to submit.
-3. Run `yarn build` to build your changes.
-4. Start Batch Submitter with `yarn start`. It will automatically start submitting pending transactions from L2.
-
-## Observability in production
-
-When deploying Batch Submitter to production / a live ETH network, populate the environment variables `NODE_ENV` (`development`, `production`, or `test`) and `ETH_NETWORK_NAME` (`mainnet`, `kovan`, `goerli`). This enables Batch Submitter to capture more context in logs and metrics, and initializes [Sentry](https://docs.sentry.io/platforms/node/) to track errors.
