Installing, Starting & Stopping The Indexer

Installation

The transaction indexer comes as a docker cluster which runs locally.

Prerequisites

​Docker should be installed and running.
Clone the Mailchain repository to your .mailchain/mailchain folder:
1
git clone https://github.com/mailchain/mailchain.git ~/.mailchain/mailchain
2
cd ~/.mailchain/mailchain
Copied!

Starting the Indexer

The indexer is preconfigured for 3 networks:
Network
Command
Edgeware Mainnet
make edgeware-mainnet
Edgeware Testnet (beresheet)
make edgeware-beresheet
Edgeware Local (development)
make edgeware-local
Select the network and run the appropriate make command (e.g. make edgeware-mainnet). This will download or update the required docker containers.
NOTE: If working in local mode, you can access the preconfigured development accounts here if you need to transfer a balance to accounts you configured in Setting Up > Add Account.
If successful, the output will be similar to the following:
1
Creating network "mailchain_default" with the default driver
2
