> yarn install
Next,rename env.example to .env and populate values
PRIVATE_KEY=<Your Wallet Private Key>
MUMBAI_RPC_URL=https://polygon-mumbai.g.alchemy.com/v2/<API_KEY>
POLYSCAN_API_KEY=<PolyScan API KEY>
> yarn hardhat deploy --network <network_name_defined_in_config>
deployment script should also verify the contract,In case it fails you can manually verify by running
yarn hardhat verify --network <networkName> <deployedContractAddress> "<constructorArgument>[in this case minterAddress]"
Run,
> yarn hardhat run scripts/createSalesOrder.js --network <network_name>
This will create file in /lazymintdapp/src/NFTVouchers.json
> yarn hardhat test
