1. 📄 Deploy the Smart Contract
Deploy ValidatorNFT.sol on 0g EVM testnet via Remix or Hardhat. Use this metadata URI as constructor parameter:
https://validatornft-0g.coinsspor.com/metadata/metadata.jsonThen copy the deployed contract address and update:
// frontend/src/config.ts
export default {
CONTRACT_ADDRESS: "0xYourDeployedContractAddress",
VALIDATORS_JSON: "/validators.json"
};2. 📰 Run Python Scripts for Whitelist
Requirements:
pip install web3 requests bech32Step 1: Fetch the top 200 active bonded validator EVM addresses
python3 whitelist-scripts/fetch_validators.pyStep 2: Push whitelist to contract in batch:
python3 whitelist-scripts/batch_whitelist_checker.py3. 🌐 Serve the Frontend
cd frontend
npm install
npm run buildHost the dist or build folder using Nginx, Vercel, Netlify, etc.
💼 Contract Functions
function setValidator(address _addr, bool _status) public onlyOwner;
function batchSetValidators(address[] calldata addrs, bool status) public onlyOwner;
function mint() public;
function hasMinted(address) view returns (bool);
function isValidator(address) view returns (bool);🚨 Security Notes
No private key is exposed in frontend
Contract prevents duplicate minting (hasMinted check)
Only contract owner can manage whitelist
Metadata/image is hosted off-chain, but safely referenced
