Cardano Local Testnet

Cardonnay

Cardonnay is a command-line tool for setting up and managing local Cardano testnets.
It supports multiple preconfigured testnet types and makes it easy to inspect and control their lifecycle.

---

🚀 Getting Started

1. Create a conway_fast testnet

$ cardonnay create -t conway_fast
Starting the testnet cluster with `/var/tmp/cardonnay-of-user/cluster0_conway_fast/start-cluster`:
[...]
Cluster started 🚀

ℹ️ Pro Tip: Add -b to create the testnet in the background, or -c "comment" to add a comment.

2. List running testnet instances

$ cardonnay control ls

[
  {
    "instance": 0,
    "type": "conway_fast",
    "state": "started",
    "comment": null
  }
]

3. Inspect the testnet faucet

$ cardonnay inspect faucet -i 0

{
  "address": "addr_test1vpgm9cj9u3k63642vju9jqgeqy393upttt0qtwptlesy08gx620qd",
  "vkey_file": "/var/tmp/cardonnay-of-user/state-cluster0/shelley/genesis-utxo.vkey",
  "skey_file": "/var/tmp/cardonnay-of-user/state-cluster0/shelley/genesis-utxo.skey"
}

4. Work with the testnet

source <(cardonnay control print-env -i 0)
cardano-cli query tip --testnet-magic 42

5. Stop all running testnet instances

$ cardonnay control stop-all
Stopping the testnet cluster with `/var/tmp/cardonnay-of-user/state-cluster0/stop-cluster`:
[...]
Cluster terminated!

🛠️ Installation

Option 1: Using Nix

If you use Nix, you can spin up a development shell with all dependencies:

nix develop

This will provide a fully set-up environment, including Python, Cardano binaries, and jq.

ℹ️ NOTE: To use the latest master branch of cardano-node, run

nix flake update --accept-flake-config --override-input cardano-node github:IntersectMBO/cardano-node/master
nix develop --accept-flake-config

---

Option 2: Using pip

Ensure the following dependencies are installed and available in your PATH:

• python3
• jq
• cardano-node
• cardano-cli
• optional: cardano-submit-api

Then install Cardonnay in a virtual environment:

# Create and activate a virtual environment
python3 -m venv .venv
source .venv/bin/activate

# Install Cardonnay
pip install -U --require-virtualenv cardonnay

# (Optional) Enable shell completions for Bash
source completions/cardonnay.bash-completion
