Stack

• packages/nextjs — Next.js 14 (App Router), TypeScript, Tailwind, wagmi 2 + viem 2 + RainbowKit 2, Apollo Client. SVG art is rendered by deploying the actual ERC721 contract bytecode in-browser via @ethereumjs/evm — no mainnet RPC needed for display.
• packages/hardhat — Hardhat workspace housing the deployed Solidity contracts (immutable, untouched). Used today only for local-fork deploys and the legacy test suite.
• Subgraph lives in simondlr/neolastics-subgraph. The frontend reads it via The Graph's hosted gateway.

Quick start

yarn install

# Frontend env
cp packages/nextjs/.env.example packages/nextjs/.env.local
# Then fill in:
#   NEXT_PUBLIC_GRAPH_API_KEY            (https://thegraph.com/studio)
#   NEXT_PUBLIC_WALLET_CONNECT_PROJECT_ID (https://cloud.walletconnect.com)

yarn dev          # next dev on http://localhost:3000
yarn build        # production build
yarn lint         # next lint

Hardhat (contracts)

Contracts are deployed and immutable. You only need this if you want to run the existing test suite or deploy a fresh copy locally.

yarn compile                  # hardhat compile
yarn test_contracts           # uses --network hardhat in-memory (no node needed)
yarn node                     # start a local hardhat node on :8545
yarn deploy_contracts_local   # deploy to localhost
yarn deploy_contracts_mainnet # deploy to mainnet (mnemonic required)

Deploy

Netlify (netlify.toml at repo root): Node 20, yarn build, @netlify/plugin-nextjs. Set NEXT_PUBLIC_GRAPH_API_KEY and NEXT_PUBLIC_WALLET_CONNECT_PROJECT_ID in the Netlify environment.
