2METAMASK_PRIVATE_KEY=0x...
3(none needed — Sourcify + BOB Explorer verify automatically)=...
4PRIVY_APP_ID=...
5PINATA_JWT=eyJhbGciOi...
6ROOTSTOCK_TESTNET_RPC_URL=https://...   # optional, a public RPC is used otherwise
7
8# 2. Fund the MetaMask account on BOB Mainnet:
9open https://faucet.bob.io
10
11# 3. Copy a mega-prompt from this repo into Lovable. One paste:
12#    - scaffolds the React app
13#    - writes the Solidity contract (with hackathon credit in NatSpec)
14#    - deploys to BOB Mainnet and verifies on BOB Explorer
15#    - wires Privy social login + sponsored tx
16#    - pins generated assets to IPFS via Pinata
17#    - exposes the contract address + BOB Explorer link in the UI
18
19# 4. Open the live BOB Explorer link. Your demo is provably onchain.
