Overview

nft-s3 is a platform that allows clients to create a ERC-721 (NFT) tokens on an EVM based chain that stores the token's metadata in a centralized repo (S3). The project is live and can be found at The Quick NFT

Requirements and Workflow

The requirements of the project were as follows:

• Create a front end (React) that will create a smart contract (ERC-721) and also create associated metadata (json and image) using the application's backend
• The backend provides a minimal value required in order to store the metadata in the central repo (AWS)
• The smart contract will include additional properties: Value provided, Account that was given the value. These will be used during validation when processing the associated NFT metadata

Architecture

Centralized Components (AWS)

The centralized components of the application use AWS services. The services in use are as follows:

• S3 for metadata (json) and image storage
• Lambda for providing configuration information to client: Broker address and Cost for example
• API gateway to host the API (JSON RPC)
• CloudFront to serve the React frontend

Decentralized Components

The decentralized components of the application include a smart contract that implements the ERC-721 interface (OpenZeppelin). The ideal blockchain to run this application on is . The use of a Web3 enabled wallet that supports the Polygon RPS is required as well (Metamask, Coinbase, etc.)
