Practical overview

When it fits

Use it when you can run a server-side service and need account-specific monitoring, Slack notifications or historical balance views for Solana accounts.

Who it is for

  • Teams monitoring mission-critical Solana token or native SOL accounts.
  • Operators tracking program accounts for deployments.
  • Teams that want Slack notifications and a Grafana view of historical balances.

Documented uses

  • Monitor selected Solana accounts at a configured polling interval.
  • Set an allowed balance-change threshold and time period for vault accounts.
  • Receive Slack notifications about balance changes and program deployments.
  • Review historical account balances in Grafana.
Before you choose

Requirements & limits

The repository is public and identifies the project as MIT-licensed. The documented deployment uses Docker Compose on a server; the README also describes a binary option with a custom PostgreSQL instance.

  • Configuration requires a Solana RPC endpoint and account public keys in base58 format.
  • Balance thresholds and time windows are optional and apply to vault accounts.
  • Slack notifications use a Slack hook URL configured through the environment file.
  • PostgreSQL stores polls, while Grafana is documented for viewing historical balances.

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

Set up Vault Watcher with Docker Compose

Prepare the repository configuration and start the documented Docker containers.

Before you start

  • A server for the containerized service
  • A Solana RPC endpoint
  • Docker Compose
  • Account public keys to monitor

Steps

  1. Clone the repository and change into its directory.

  2. Copy _accounts.json to accounts.json, _config.json to config.json, and _.env to .env.

  3. Edit accounts.json and config.json with the accounts and Solana RPC settings; optionally edit .env for environment variables such as the Slack hook URL.

  4. Run sudo docker-compose build, then sudo docker-compose up.

Expected outcome

The containers are started; the README says a Grafana dashboard is available at http://localhost:3000 by default, with PostgreSQL available for balance history.

Guide limitations

  • The guide documents starting the containers, not verification of alerts or monitoring results.
  • The README describes a custom PostgreSQL instance as an alternative when running the service directly as a binary.
