NFTpay

Make your own blockchain-hosted invoices - hosted for free on IPFS and fulfilled by cryptocurrency.

Built for the NFThack2022 hackathon.

• Free hosting for invoice checkout pages.
• No need to open a partnership with an external vendor for managing invoices, or paying vendor-specific fees such as those from Stripe.
• Receipts auto-hosted as NFT's. No chance of losing an attachment or document showing the time and receipt of purchase. Receipt and time of purchase forever retained on ethereum's network.
• Payments facillated and settled on crypto. Use either credit card or your ERC20 token of choice to settle the payment.
• On successful payment callback, receipts represented as NFTs are delivered by the app to both the buyer and seller wallets after the transaction.

• IPFS/Filecoin: Hosting of the invoice metadata on IPFS with it's own NFT contract. Invoice metadata saved in a static IPFS-served json file.

• Unlock Protocol: Creates an ethereum based paywall where a user chooses an Ethereum wallet as the checkout method of choice.
• Circle: Enables settling transactions in USDC using credit card directly from the invoice checkout screen.
• Superfluid: Continuous stream invoice support (usable for subscriptions/licensing). Option to set up a superfluid flow on the invoice checkout page.

• Covalent: Transaction history / lookup. After transactions are completed, Covalent can be used for destination address lookup to view the history on a particular network in a user-friendly table format in-app.
• NFTPort: Creation of the NFT payment receipts for arbitrary addresses and blockchains (Filecoin could have potentially been used as well).

This project is a hackathon prototype and would require additional work to be production ready (i.e. around some of the final checkout flows).

To run/demo the project locally, NFTpay requires the following environment variables.

    REACT_APP_NFT_KEY={YOUR_NFT_STORAGE_KEY} # NFT storage key for IPFS.
    REACT_APP_COVALENT_KEY={YOUR_COVALENT_API_KEY} # Covalent key for the history page.
    REACT_APP_NFT_PORT_KEY={YOUR_NFT_PORT_API_KEY} # NFT port api key for receipt creation.

After declaring the above environment variables, use the below command to start the project:

yarn && yarn start
