Mina Explorer

Block explorer for Mina Protocol built with Next.js 15, TypeScript, and Tailwind CSS. Supports testnet, devnet, and mainnet networks.

Setup

npm install

Copy the example env file and fill in your server URLs:

cp .env.local.example .env.local

Edit .env.local with your Mina node endpoints:

# Base path for reverse proxy (leave empty if serving from root)
NEXT_PUBLIC_BASE_PATH=/lightnet/explorer

# Testnet
TESTNET_GRAPHQL_URL=http://YOUR_SERVER:9080/graphql

# Devnet
DEVNET_GRAPHQL_URL=http://YOUR_SERVER:6085/graphql
DEVNET_ROSETTA_URL=http://YOUR_SERVER:3087

# Mainnet
MAINNET_GRAPHQL_URL=http://YOUR_SERVER:7085/graphql
MAINNET_ROSETTA_URL=http://YOUR_SERVER:4087

Note: Endpoint URLs intentionally have no NEXT_PUBLIC_ prefix so they stay server-side only. Client requests go through /api/graphql and /api/rosetta proxy routes.

Development

npm run dev

To expose on all interfaces (e.g. on a remote server):

npm run dev -- -H 0.0.0.0 -p 3000

Production

npm run build
npm run start

Base Path

The app is configured with basePath: "/lightnet/explorer" in next.config.ts for deployment behind a reverse proxy. Change or remove this if serving from root.
