The documentation here uses instructions from IOHK repositories as a foundation, with additional info which we can contribute to where appropriate. Note that not everyone needs to build each component. You can refer to architecture to understand and qualify which of the components built by IO you want to run.


For most Pool Operators, simply building cardano-node should be enough. Use the below to decide whether you need other components:

  A([Interact with HD Wallets<br/>locally])
  B([Explore blockchain<br/>locally])
  C([Easy pool-ops and<br/>fund management])
  D([Create Custom Assets])
  E([Monitor node <br/>using Terminal UI])
  F([Sign/verify any data<br/>using crypto keys])
  T(Tx Submit API)

We strongly prefer use of gRest over GraphQL components due to performance, security, simplicity, control and most importantly - consistency benefits. Please refer to official documentations if you're interested in GraphQL or Cardano-Rest components instead.


The instructions are intentionally limited to stack/cabal** to avoid wait times/availability of nix/docker files on a rapidly developing codebase - this also helps us prevent managing multiple versions of instructions.

Description for components built by community⚓︎


A swiss army knife for pool operators, primarily built by Ola, to simplify typical operations regarding their wallet keys and pool management. You can read more about it here


A local node monitoring tool, primarily built by Ola, to use in addition to remote monitoring tools like Prometheus/Grafana, Zabbix or IOG's RTView. This is especially useful when moving to a systemd deployment - if you haven't done so already - as it offers an intuitive UI to monitor the node status. You can read more about it here

Topology Updater⚓︎

A temporary node-to-node discovery solution, run by Markus, that was started initially to bridge the gap created while awaiting completion of P2P on cardano network, but has since become an important lifeline to the network health - to allow everyone to activate their relay nodes without having to postpone and wait for manual topology completion requests. You can read more about it here


A full-featured local query layer node to explore blockchain data (via dbsync) using standardised pre-built queries served via API as per standard from Koios - for which user can opt to participate in elastic query layer. You can read more about build steps here and reference API endpoints here


A lightweight bridge interface for cardano-node. It offers a WebSockets API that enables local clients to speak Ouroboros' mini-protocols via JSON/RPC. You can read more about it here


A CLI tool written in Rust by Andrew Westberg for low-level communication with cardano-node. It is commonly used by SPOs to check their leader logs (integrates with CNTools as well as gLiveView) or to send their pool's health information to You can read more about it here

Cardano Signer⚓︎

A tool written by Martin to sign/verify data (hex, text or binary) using cryptographic keys to generate data as per CIP-8 or CIP-36 standards. You can read more about it here
