# Testnet or mainnet
NETWORK=testnet
# Absolute path where keys/policy files etc. are generated and stored
WORKING_DIR_EXTERNAL=/home/peter/nft-dropper-composed/work
# Your price for one token
TOKEN_PRICE=10
# Maximum tokens to buy per transaction
TOKEN_MAX_AMOUNT=5
# Address where you want to receive the winnings
SELLER_ADDRESS=addr_test1qq487jh48qysllv3d0peafg76gqhp3ys3ycpy94rwza3tk4578p0hapx37mcflefvvwyhwtwn4kt83nkf7wqwx9tvsdshrgzfj
# A docker volume where node.socket is present to connect to the cardano-node. You can leave it as it is, as long the docker-compose.yml is in a dir named nft-dropper-composed (default if you extract the zip)
IPC_VOLUME_NAME=nft-dropper-composed_node-ipc

Prepare the nft-source folder

• Adapt the metadata.json to your metadata (the keys of the main object are the filenames)
• Put the image files in the folder
• The image filenames define the assetname: StringUtils.left(FilenameUtils.getBaseName(filename).replaceAll("[^a-zA-Z0-9]", ""), 32)
• While minting the images are uploaded to ipfs and the image attribute in the metadata gets added/updated with the ipfs url

Edit the template

• Just edit the tymeleaf template at templates\index.html to your needings.
• Edit the css at static\styles\styles.css to your needings.
• Add new static recources like images to the static folder and insert like <img th:src="@{/image.jpg}">
• Changes on the template need a sudo docker-compose restart nft-dropper to take effect.

Start

Start it with

sudo docker-compose up -d

Show logs with

sudo docker-compose logs -f

The first start on testnet will take several hours until db-sync is synchonized, mainnet can take up to 48 hours.

API

There is also a small API if you wanto to integrate it into another page:

http://cardano-tools.io:8081/api/tokensLeft

http://cardano-tools.io:8081/api/address

Pricing

Every mint transaction (independent from the amount of tokens) sends 1₳ to the [EURO]-Pool pledge. So a minimum price of 5₳ per token is recommended to avoid errors.
