This is a Next.js project bootstrapped with create-next-app.

Installation

First, run the development server:

npm install
npm run dev

Environment Variables

All three are read at build time (next build inlines them) and the build fails if one is missing or malformed.

# Starknet JSON-RPC URL used for mainnet (RPC spec 0.10, must send CORS headers: the browser calls it directly).
# Production uses the Carbonable RPC gateway, which only answers requests coming from https://app.carbonable.io,
# so local development needs a public RPC instead, for example https://starknet-rpc.publicnode.com
NEXT_PUBLIC_MAINNET_RPC_URL=https://starknet-rpc.publicnode.com
# Starknet JSON-RPC URL used for Sepolia (same requirements)
NEXT_PUBLIC_SEPOLIA_RPC_URL=https://starknet-sepolia-rpc.publicnode.com
# Network selected when no wallet is connected
NEXT_PUBLIC_DEFAULT_CHAIN=mainnet|sepolia

Configuration

Edit the file config/projects.ts

Start the server

npm run dev

Open http://localhost:3000 with your browser to see the result.

Deploy

Production is built by Dokploy from the Dockerfile, which takes the three variables above as build args (NEXT_PUBLIC_MAINNET_RPC_URL, NEXT_PUBLIC_SEPOLIA_RPC_URL, NEXT_PUBLIC_DEFAULT_CHAIN). The mainnet URL carries the RPC gateway key: never print it in a build log or a shell history.
