Rust NFT API is a simple RESTful API developed in Rust that offers functionalities for creating, retrieving, and listing Non-Fungible Tokens (NFTs) on the Ethereum blockchain, along with managing their off-chain metadata.

Before setting up the Rust NFT API, ensure you have the following components ready:

1. Ethereum Node: An Ethereum test node, such as Ganache, for local blockchain simulation.
2. IPFS: IPFS Desktop or similar for off-chain data storage, to test locally.
3. Smart Contract Deployment Tool: Remix IDE or another tool for deploying the Smart Contract to the Ethereum blockchain.

Follow these steps to set up and run the Rust NFT API:

Launch Ganache to initiate a local Ethereum blockchain node.

Using Remix IDE or your preferred tool, deploy the MyNFT.sol smart contract located in the contract folder of this project.

Run your IPFS node to handle off-chain metadata storage. If using IPFS Desktop, simply open the application.

Edit the .env file in the project's root directory to set the necessary environment variables:

`ETH_NODE_URL=http://localhost:8545 CONTRACT_ABI_PATH=./MyNFT.json MOCK_PRIVATE_KEY=69440d76b64f2418574043fbd79f3d4f56c293290c3056fc18b62b12013db7e7 # This is a placeholder for testing

TEST_OWNER_ADDRESS= TEST_TOKEN_ID=1 # Default to 1 TEST_CONTRACT_ADDRESS=`

Compile the project using Cargo:

bashCopy code

cargo build

Execute the project's test suite to verify the setup:

bashCopy code

cargo test

If any tests fail, revisit the previous setup steps to troubleshoot.

Start the Rust NFT API server by providing the deployed smart contract's address as a command-line argument (matching the TEST_CONTRACT_ADDRESS in .env):

bashCopy code

cargo run -- <Deployed_Smart_Contract_Address>

Access the Swagger UI at http://localhost:3010/swagger-ui to interact with the API through a graphical interface or use your preferred tool to call the API endpoints directly.

• Ensure Ganache and the IPFS node are running before starting the Rust NFT API server.
• The MOCK_PRIVATE_KEY provided in the .env example is for demonstration purposes only. Never use real private keys in your development environment or commit them to version control.
• For any issues or contributions, feel free to open an issue or a pull request in the repository.
