Run in release mode with a custom configuration using environment variables:

Linux / Mac
Windows

GENESIS_VERIFICATION_KEY=$(wget -q -O - **YOUR_GENESIS_VERIFICATION_KEY**) AGGREGATOR_ENDPOINT=**YOUR_AGGREGATOR_ENDPOINT** ./mithril-client

$env:GENESIS_VERIFICATION_KEY = curl.exe --silent - **YOUR_GENESIS_VERIFICATION_KEY**; $env:AGGREGATOR_ENDPOINT=**YOUR_AGGREGATOR_ENDPOINT**; .\mithril-client

tip

To display results in JSON format for the list and show commands, simply use the --json (or -j) option:

Linux / Mac
Windows

./mithril-client cardano-db snapshot list --json

.\mithril-client cardano-db snapshot list --json

tip

If you wish to delve deeper and access several levels of logs from the Mithril client, use the following:

Add -v for some logs (WARN)
Add -vv for more logs (INFO)
Add -vvv for even more logs (DEBUG)
Add -vvvv for all logs (TRACE).

Download the pre-built binary

Linux / Mac
Windows

You can install a the latest released binary of the mithril-client by running this one line command (replace YOUR_PATH with your installation path):

curl --proto '=https' --tlsv1.2 -sSf
https://raw.githubusercontent.com/input-output-hk/mithril/refs/heads/main/mithril-install.sh
| sh -s -- -c mithril-client -d latest -p YOUR_PATH

tip

You can also install the mithril-client binary for other distributions:

use -d unstable for the unstable version
use -d **DISTRIBUTION_VERSION** for a specific distribution (e.g. -d 2445.0)

info

The Linux binaries target glibc, and have a minimum requirement of glibc 2.35 (compatible with Ubuntu 22.04 or Debian 12 - Bookworm).

Run a Docker container

Registry image

A list of available images on the registry can be found here.

To prepare the environment variables, retrieve the values from the Mithril networks section.

Linux / Mac
Windows

export MITHRIL_IMAGE_ID=**YOUR_MITHRIL_IMAGE_ID**
export AGGREGATOR_ENDPOINT=**YOUR_AGGREGATOR_ENDPOINT**
export GENESIS_VERIFICATION_KEY=$(wget -q -O - **YOUR_GENESIS_VERIFICATION_KEY**)
export SNAPSHOT_DIGEST=latest

$env:MITHRIL_IMAGE_ID="**YOUR_MITHRIL_IMAGE_ID**"
$env:AGGREGATOR_ENDPOINT="**YOUR_AGGREGATOR_ENDPOINT**"
$env:GENESIS_VERIFICATION_KEY = curl.exe --silent - **YOUR_GENESIS_VERIFICATION_KEY**
$env:SNAPSHOT_DIGEST="latest"

Here is an example configuration for the release-preprod network and the latest stable Docker image:

Linux / Mac
Windows

export MITHRIL_IMAGE_ID=latest
export AGGREGATOR_ENDPOINT=https://aggregator.release-preprod.api.mithril.network/aggregator
export GENESIS_VERIFICATION_KEY=$(wget -q -O - https://raw.githubusercontent.com/input-output-hk/mithril/main/mithril-infra/configuration/release-preprod/genesis.vkey)
export SNAPSHOT_DIGEST=latest

$env:MITHRIL_IMAGE_ID="latest"
$env:AGGREGATOR_ENDPOINT="https://aggregator.release-preprod.api.mithril.network/aggregator"
$env:GENESIS_VERIFICATION_KEY = curl.exe --silent - https://raw.githubusercontent.com/input-output-hk/mithril/main/mithril-infra/configuration/release-preprod/genesis.vkey
$env:SNAPSHOT_DIGEST="latest"

Proceed by creating a shell function for the Mithril client:

Linux / Mac
Windows

mithril_client () {
  docker run --rm -e GENESIS_VERIFICATION_KEY=$GENESIS_VERIFICATION_KEY -e AGGREGATOR_ENDPOINT=$AGGREGATOR_ENDPOINT --name='mithril-client' -v $(pwd):/app/data -w /app/data -u $(id -u) ghcr.io/input-output-hk/mithril-client:$MITHRIL_IMAGE_ID $@
}

function mithril_client {
  docker run --rm -e GENESIS_VERIFICATION_KEY=$env:GENESIS_VERIFICATION_KEY -e AGGREGATOR_ENDPOINT=$env:AGGREGATOR_ENDPOINT --name='mithril-client' -v ${PWD}:/app/data -w /app/data ghcr.io/input-output-hk/mithril-client:$env:MITHRIL_IMAGE_ID $args
}

Now you can use the mithril_client functions:

mithril_client help

# 2- List Cardano db snapshots
mithril_client cardano-db snapshot list

# 3- Show detailed information about a Cardano db snapshot
mithril_client cardano-db snapshot show $CARDANO_DB_DIGEST

mithril_client cardano-db download --include-ancillary --ancillary-verification-key $ANCILLARY_VERIFICATION_KEY $CARDANO_DB_DIGEST

# 5- List Mithril stake distributions
mithril_client mithril-stake-distribution list

# 6- Download and verify the given Mithril stake distribution
mithril_client mithril-stake-distribution download $MITHRIL_STAKE_DISTRIBUTION_ARTIFACT_HASH

# 7- List Cardano transaction snapshots
mithril_client cardano-transaction snapshot list

# 8- Show detailed information about a Cardano transaction snapshot
mithril_client cardano-transaction snapshot show $CARDANO_TRANSACTION_SNAPSHOT_HASH

# 9- Certify that the given list of transactions hashes are included in the Cardano transactions set
mithril_client cardano-transaction certify $TRANSACTION_HASH_1,$TRANSACTION_HASH_2

# 10- List Cardano stake distributions
