The MobyMask watcher is a Laconic Network component that provides efficient access to MobyMask contract data from Ethereum, along with evidence allowing users to verify the correctness of that data. The watcher source code is available in [this repository](https://github.com/cerc-io/watcher-ts/tree/main/packages/mobymask-watcher) and a developer-oriented Docker Compose setup for the watcher can be found [here](https://github.com/cerc-io/mobymask-watcher). The watcher can be deployed automatically using the Laconic Stack Orchestrator tool as detailed below:
The instructions below show how to deploy a MobyMask watcher using laconic-stack-orchestrator (the installation of which is covered [here](https://github.com/cerc-io/stack-orchestrator#install)).
This deployment expects that ipld-eth-server's endpoints are available on the local machine at http://ipld-eth-server.example.com:8083/graphql and http://ipld-eth-server.example.com:8082. More advanced configurations are supported by modifying the watcher's [config file](../../config/watcher-mobymask/mobymask-watcher.toml).
Correct operation should be verified by following the instructions [here](https://github.com/cerc-io/mobymask-watcher/tree/main/mainnet-watcher-only#run), checking GraphQL queries return valid results in the watcher's [playground](http://127.0.0.1:3001/graphql).
