- op-conductor-mon: Monitors multiple op-conductor instances and provides a unified interface for reporting metrics.
- op-signer: Thin gateway that supports `eth_signTransaction` RPC endpoint to sign ethereum tx payloads using private key stored in KMS
- op-ufm: User facing monitoring creates transactions at regular intervals and observe transaction propagation across different RPC providers.

# op-conductor-ops
op-conductor-ops is a CLI tool for managing op-conductor sequencer clusters.
**WARNING!!! This tool can cause a network outage if used improperly. Please consult #pod-devinfra before using.**
## Setup
Requires [poetry](https://github.com/python-poetry/poetry).
Install python dependencies with `poetry install`.
Recommended updates to your .bashrc/zshrc:
1. `export PATH="export PATH="<path-to-infra-repo>/op-conductor-ops:$PATH""`
2. `export CONDUCTOR_CONFIG="<path-to-op-conductor-ops-config.toml>"`
## Usage
After installing dependencies with `poetry`, the tool can be invoked with `./op-conductor-ops`,
which just calls `poetry run python main.py` and passes on any arguments.
### Example Usage
* Example usage with implicit config file with lookup at ./config.toml
```./op-conductor-ops status <network-name>```
* Usage with explicit path to config and certificate
```./op-conductor-ops -c ./<path>/config.toml --cert ./<path>/cacert.pem <command> <network-name>```
## Example Configuration File: example.config.toml
This configuration file is used to set up the networks and sequencers for your application.
### Structure
The configuration file is divided into two main sections:
1. **Networks**: This section defines the networks that your application will use. There is an example network configuration (`op-network-1`) and a blank network configuration (`op-network-N`) for you to fill out.
2. **Sequencers**: This section defines the sequencers for each network. Again, there is an example sequencer configuration for `op-network-1` and a blank sequencer configuration for `op-network-N`.
Is is recommended to update the network name and sequencer names for your specifc configuration in the toml object declaration
### Config Usage
1. Copy this file to `config.toml` in your application's root directory.
2. Modify the example configurations or fill out the blank configurations as needed for your application.
3. Save the `config.toml` file and use it to configure your application's networks and sequencers.
Remember, the example configurations are provided for your convenience, but you should review and update them to match your specific requirements.

# op-txproxy
A supplemental passthrough proxy for some execution engine endpoints. This proxy does not forward all rpc traffic and only exposes a specific set of endpoints.
Operationally, the public ingress proxy should only re-route requests for these endpoints.
```mermaid
stateDiagram-v2
proxyd --> txproxy: intercepted methods
proxyd --> backend: unintercepted methods
txproxy --> backend
```
## Setup
Install go 1.21
```
make build
./bin/op-txproxy --help
```
## Endpoints
### eth_sendRawTransactionConditional
An outcome of how to integrate this [spec](https://notes.ethereum.org/@yoav/SkaX2lS9j) safely for permissionless 4337 bundler participation. This solution in the design doc [proposal](https://github.com/ethereum-optimism/design-docs/blob/main/ecosystem/sendRawTransactionConditional/proposal.md)
requires a validating proxy that can be horizontally scaled and pre-emptively reject invalid conditional transaction. The implemented endpoint covers
these objectives:
1. **Auth**. preemptively put in place to enable a variety of auth policies (allowlist, rate limits, etc).
The caller authenticates themselves with any valid ECDSA-secp256k1 key, like an Ethereum key. The computed signature is over the [EIP-191](https://eips.ethereum.org/EIPS/eip-191) hash of the request body (up to the 5MB request body limit).
With the signature and signing address, the request is authenticated via the `X-Optimism-Signature` header of the request with the value `<public key address>: <signature>`.
2. **Rate Limits**. global rate limits on the endpoint are applied here.
2. **Rejection Switch**. this proxy can be rolled with a flag/env switch to reject conditional transaction without needing to interrupt the execution engine.
3. **Basic Validation**. stateless validation is done in the endpoint to reject invalid conditional transactions and apply additional restricts on the usage (only 4337 entrypoint tx target support).
4. **Metrics**. performance of this endpoint can be observed in order to inform adjustments to rate limits, shutoff, or auth policies to implement.
