Watchers make managing data in Dapp development as frictionless as possible. They do this by querying, transforming, and caching Ethereum state data cheaper and faster compared to existing solutions. This data also comes with evidence for generating cryptographic proofs to provide verification that the data is authentic. Public watchers are found in the [packages](/packages) directory.
Go [here](https://github.com/cerc-io/stack-orchestrator/tree/main/app/data/stacks/erc20) for a quick start demo of setting up the stack and deploying/using the erc20 watcher via the Laconic Stack Orchestrator.
You'll need the above if you plan on digging into this repo, writing your own watchers, or experimenting with watchers not currently supported by Stack Orchestrator. See [CONTRIBUTING.md](.github/CONTRIBUTING.md) for more information.
These services are dockerized by the Laconic Stack Orchestrator (`laconic-so`). [Use it](https://github.com/cerc-io/stack-orchestrator) unless you plan on digging into those codebases. For more information on setting up these services up by hand, see [here](/docs/README.md)
Orient yourself with the available CLI commands [here](docs/cli.md) and in some cases, watchers have in-depth demos (e.g. [mobymask](/packages/mobymask-watcher))
