NFT Certificates for the Ethereum Bootcamp

Add working metadata

1. Add certificate images to metadata/images
2. Make sure metadata/cohort1.json and metatadata/storeScriptOp.json has the complete details of cohort members

Upload certificates to IPFS

npx ts-node scripts/store.ts --cohortId 1 --sourceDataPath metadata/cohort1.json --outputPath metadata/storeScriptOp.json --imagesPath metadata/images

• cohortId - Cohort ID
• sourceDataPath - Path to source data json file
• outputPath - Path to output json file containing IPFS hashes to certificate metadata
• imagesPath - Path to images directory to pick image for certificate

Deploy the Certificate contract

npx hardhat node
npx hardhat run scripts/deploy.ts --network <network_name>

network_name can be localhost or rinkeby or mainnet, depending on where you intend to deploy

The address of the deployed contract is saved in metadata/deployedAddress.json

Award the respective certificate images as NFTs

npx hardhat run scripts/awardNFT.ts --network <network_name>

NOTE: it is important that the hardhat network be the same when deploying contract and awarding certificates. Also, npx hardhat command always creates and tears down the local network, so use npx hardhat node beforehand to avoid errors.
