Jade Explorer, A Minimal Block Explorer for the Ethereum Stack

3 min readSep 18, 2019

Jade Explorer is a minimal block explorer for the Ethereum Stack. The explorer utilizes Jade Service Runner for managing background services (Multi-Geth), OpenRPC for underlying functionality, and Pristine. It does not use a database and can be configured to point at any remote RPC node for any EVM-based network. The goal of Jade Explorer is to provide a resource for network information and block exploration.

Explorer Features:

Display chain id
Syncing status
Runtime configuration for endpoints
Search by Block, Transaction, Address
Charts for hash, transaction count, gas used, uncles
Preview latest blocks

Need a block explorer for your EVM-based client? Just add it in the url https://explorer.jade.builders/?rpcUrl=https://. Here are some examples:

ETC mainnet https://explorer.jade.builders/?rpcUrl=https://www.ethercluster.com/etc
Kotti (ETC testnet) https://explorer.jade.builders/?rpcUrl=https://www.ethercluster.com/kotti
ETH mainnet https://explorer.jade.builders/?rpcUrl=https://main-rpc.linkpool.io/
Goerli (ETH testnet) https://explorer.jade.builders/?rpcUrl=https://rpc.slock.it/goerli

Maybe you want to see how much the DAO hacker HODLs lol

Install

Dependencies

at least node v10.15.3
at least npm v6.4.1

Clone the repository and install project dependencies.

git clone https://github.com/etclabscore/jade-explorer.git && cd jade-explorer && npm install

Usage

Service Runner

If you don't have a service-runner running you can use the one in the package.json via: (or see the configuration section below to provide your own ethereum rpc URL):

npm run service-runner

Jade Service Runner will run at http://localhost:8002/.

Start the explorer.

npm start

The explorer will run at http://localhost:3000/ which should display multi-geth's status, and make sure multi-geth is running.

Notes on Multi-Geth & Service Runner

By default, multi-geth service will run ETC mainnet. Jade Service runner conveniently contains the service in the /.services/ directory of project.

# ./services/
.
└── multi-geth
    └── 1.9.2
        └── multi-geth
            └── 1.9.2
