Contracts

NFT ERC721 smart contract in contracts/. Inherits from OpenZeppelins ERC721 contract.

To Re-Compile

npx hardhat compile --force

Deploying

Currently the deploy function is in src/scripts/ and it places the binary/abi generated from hardhat compilation in artifacts/. Artifacts are used for contract deployment in the createOrg lambda function. Use npx ts-node scripts/deploy-nft-contract to deploy a contract manually and visit the file itself to change the props.

Middleware
