  • Create dashboards for monitoring blockchain accounts and smart contracts.
  • Operate a self-hosted blockchain data stack.
Before you choose

Requirements & limits

The repository describes the API as access-controlled. It documents a Docker Compose setup for self-hosting.

  • The API serves data for blockchains crawled by Moonstream.
  • The API is access-controlled.
  • The documented self-hosting setup uses Docker Compose and requires environment configuration, including a PostgreSQL URI.
  • The repository identifies Apache-2.0 as its license.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Prepare Moonstream for a Docker Compose setup

Generate the documented environment files and start the local Docker Compose setup.

Before you start

  • The Moonstream repository
  • Docker Compose
  • A PostgreSQL connection URI configured through the database environment-generation step

Steps

  1. Run ./backend/configs/docker_generate_env.bash to prepare the API environment file.

  2. Run ./db/configs/docker_generate_env.bash to prepare the database configuration, including its PostgreSQL URI.

  3. Run docker-compose up --build for the documented local setup.

Expected outcome

The documented Docker Compose setup is started locally, with the API and database environment configuration prepared.

Guide limitations

  • The repository says environment variables and the database connection must be configured; it does not specify values for a particular deployment.
