Transaction Stream Service
The Indexer API, Transaction Stream Service, and Custom Processors are currently in beta. Please report any problems you encounter by creating an issue in the [aptos-indexer-processors](https://github.com/aptos-labs/aptos-indexer-processors/issues/new/choose) repo.
The Transaction Stream Service is a service that listens to the Aptos blockchain and emits transactions as they are processed. These docs explain how this system works, how to use the Labs-Hosted instance of the service, and how to deploy it yourself.
