Example Deploy Ainft Polygon

This README is written by chatGPT and revised by human being.

This repository contains the necessary code to deploy an ERC721 contract on the Polygon testnet and mint generative AI art as non-fungible tokens (NFTs). It also includes scripts to upload the art to IPFS using IPFS-http-client and pinata, and to change the NFT metadata URI.

Installation

Before running the deployment and minting scripts, you will need to install the following dependencies:

• Node.js v14 or higher
• Hardhat
• IPFS-http-client
• Pinata SDK You can install the dependencies using the following command:

yarn install

Configuration

Before deploying the contract and minting the NFTs, you need to configure the deployment and minting scripts. You can refer the configuration template env.template.

In the configuration file, you need to provide the following information:

POLYGON_RPC_URL=
PRIVATE_KEY=

INFURA_PROJECT_ID=
INFURA_SECRET_KEY=

PINATA_API_KEY=
PINATA_SECRET_KEY=

AIN_PRIVATE_KEY=

You can obtain the necessary information by following the instructions provided by Infura, IPFS, and Pinata. When using Infura, you must initialize IPFS project first.

If you feel hard to make AIN account, use this as private key for testing: 4376186267ffc7c8472fa9992a67a4c98db50888e15ed187d53602763e70bbfb. You only use this key for testing, not for commercial use.

Deployment

To deploy the ERC721 contract on the Polygon testnet, run the following command:

# for mumbai testnet
npx hardhat run scripts/deploy-contract.ts --network polygon
# for local
npx hardhat run scripts/deploy-contract.ts --network hardhat

This will deploy the contract to the Polygon testnet using the specified configuration.

Usages of Scripts

You can try the mint & update scheme of making generative AINFT by following 3 steps:

1. npx hardhat run scripts/deploy-contract.ts --network <NETWORK_NAME>
2. npx hardhat run scripts/first-mint.ts --network <NETWORK_NAME>
3. npx hardhat run scripts/update-nft.ts --network <NETWORK_NAME>

Step 1. Deploy the ERC721 contract on polygon network You can experience AINFT by using sample contract(GenerativeAINFT.sol). Execute on shell:

npx hardhat run scripts/deploy-contract.ts --network <NETWORK_NAME>

Then, you can get a contract address - <CONTRACT_ADDRESS>.

Step 2. Mint the generative AI NFT from generated contract In scripts/first-mint.ts, you should change the values inside params, especially contract address. Then, execute on shell:

npx hardhat run scripts/first-mint.ts --network <NETWORK_NAME>

You can get metadataCIDs.

Step 3. Update the metadata and change the appearance In scripts/updated-asset.ts, you can update the metadata with newly generated images. You also change the values in params inside script same as Step 2.

npx hardhat run scripts/update-nft.ts --network <NETWORK_NAME>

The metadata is updated and the changes are all logged to AIN network!
