Hyperledger Indy Transaction Explorer

  • IndyScan is transaction explorer for Hyperledger Indy blockchain.
  • IndyScan for Sovrin public blockchain is deployed @

How it works?

  • The indyscan-daemon checks ledger for new transactions.
  • Transactions are stored in Elasticsearch (storage format info)
  • indyscan-webapp is web UI to browse and explore transaction data.
  • indyscan-api provides HTTP API to query transaction data.

Start locally in localhost

The easiest way to get started with indy. Follow this to startup locally Indypool with Indyscan attached out of the box.

Start in AWS

Second option is running in AWS. Follow this to startup Indypool with Indyscan attached out of the box in AWS.

Custom deployments or running on host


  • you want to run Indyscan on your host machine
  • you want to run Indyscan against some particular Indy network
  • you want to deploy Indyscan on intranet you will find useful more info about the individual services you need and how to configure them. Before you dig in, try to dig into docker configuration provided here for running on localhost you might just figure small modification you need to do for your use case.
