Ethereum analysis services 🦇🔊🔍

The backend services to ultrasound.money which analyze Ethereum.

These services are written with ultrasound.money in mind. That is to say, this is not code we expect anyone to build on top of. At the same time, we do encourage peeking under the hood, making suggestions, raising issues, and re-using whatever is useful to you.

To give a rough overview of the code: there are many binaries, all invoking top-level functions from lib.rs. Some are intended to run as cronjobs, others continually listen and react to Ethereum node events, and yet others serve API requests.

Dependencies

  • Postgres
  • Execution client (tested with Geth)
  • Consensus client (tested with Lighthouse)
  • Etherscan API key (required for issuance breakdown)
  • Glassnode API key (required for supply projections)
  • OpsGenie API key (required for phoenix, alert service)

Environment Variables

BEACON_URL=http://****:5052
DATABASE_URL=postgresql://****
ETHERSCAN_API_KEY=****
GETH_URL=ws://****:8546/
GLASSNODE_API_KEY=****
OPSGENIE_API_KEY=****
SQLX_OFFLINE=true

Usage

For runnable binaries see the bin folder in this repo. After making any required env vars available one executes with cargo, e.g.

RUST_LOG=info,sqlx=warn cargo run --bin sync-beacon-states

Logs

Pass the env var RUST_LOG e.g. RUST_LOG=debug,sqlx=warn,hyper=info cargo run --bin serve. For more examples see the env_logger docs.
