Highwind is a tool that allows you to deploy NFT smart contracts through a Graphic User Interface (GUI). With Highwind you can easily create and mint items that can be sold on OpenSea.

Leveraging Streamlit, Docker and web3 this tool is run on your local machine and works straight out of the box without any advanced configruation.

• docker (https://docs.docker.com/get-docker/)

In order to streamline deployments, Highwind leverages these 3rd party APIs. You must register and get an API key from these services to use Highwind

Infura is a blockchain development suite that provides easy access to Ethereum networks.

Pinata provides an API to easily interact with IPFS

MetaMask is a software cryptocurrency wallet used to interact with the Ethereum blockchain.

Here is how you can easily get started using Highwind

git clone https://github.com/banjtheman/highwind.git
cd highwind
./build_docker.sh
./run_docker.sh
# view website on localhost:8501

With Highwind you can deploy Smart Contracts easily just by entering in your wallet info and infura key. You will need to have some ETH/MATIC in your wallet depending on the network. The faucet links are displayed in the UI.

With Highwind, you can easily create item metadata that is uploaded to IPFS powered by Pinata. Simply enter in the infromation and press the Pin button

Once you have created an item, you can now mint it on the blockchain. Enter the address you would like to send the NFT to, and press the mint button.

Once items have been minted, you can view your collection and items on OpenSea.

You can also run a standalone scripts to interact with NFTs

This script allows you to mint and NFT with a token metadata URL from a contract and send the NFT to an address.

You need to set some environment variables, and pass in arguments to get the script to work. Here is an end-to-end example

./build_docker.sh
./run_docker.sh
docker exec -it DOCKER_HASH
cd scripts/
export PUBLIC_KEY=PUBLIC_KEY
export PRIVATE_KEY=PRIVATE_KEY
export INFURA_KEY=INFURA_KEY
export NETWORK="mumbai"
python mint_nft.py --contract_address CONTRACT_ADDRESS --abi_path ABI_PATH --to_address TO_ADDRESS --token_metadata_url

Example running the script

python mint_nft.py --contract_address "0x6DF98FB9cDfDa02F7d0A53c544520A3a2f9E6eC8" --abi_path "../build/contracts_WitcherCoin/WitcherCoin.json" --to_address "0xd714c8126D36b286d88c4F5Dc7f7f361b92acF11" --token_metadata_url "ipfs://QmSjxUGeqbUSFL5KWwV1x9aGw7QfygmjDiqM2MLhJdr9kP"

Example output

If you want to mint a bunch of NFTs can easily add in looping logic but be weary of gas fees.
