Install

To run the node.js examples, first install dependencies via:

npm ci

Obtain tokens from the faucet

To send write transactions to the LAOS network, the sender needs to own a minimal amount of funds. Please use this faucet if needed.

Set up the .env file

Rename the example.env file to .env, and fill in the three fields:

• The private key field must start with 0x..., and the corresponding account must have acquired tokens from the faucet. This field is required.
• The examples use Pinata to upload and store data in IPFS. To use the ipfs-uploader.js example, either use your Pinata API key or create a free Pinata account to get one. Paste the key and secret in the fields in the .env file. If you are minting using IPFS addresses from different source, you need not fill in these fields.

Run the scripts

Each script contains comments in its code that should make it understandable. Modify the required values to adapt to your needs (e.g. contract addresses, recipient of mints, etc.).

Run the scripts via:

node script_name.js

Minting an asset on Ethereum or Polygon

The fastest way to bridgelessly mint an asset on Ethereum or Polygon (without paying any ETH or MATIC) is to use existing collections that have Public Minting enabled.

The steps are as follows:

1. Place an image that you would like to be associated with the asset in the ./imgs folder.
2. Edit the main() function of the ipfs-uploader.js script to use the path to the image, as well as the title, description, and associated metadata of the asset. Run the script.
3. Paste the resulting ipfs://... output from ipfs-uploader.js into the tokenURI variable of the single-mint.js script.
4. Ensure that the klaosCollectionAddr and toAddress variables are set to your requirements, as explained in the script comments. Run the script.
5. The output of the script is a tokenID.

If you used the suggested public collections in the example, the minted assets can be viewed at:

• For assets minted in the Ethereum public contract: https://apps.klaos.io/asset/1/0x56d77B72C8A7322D2F63bBd17EacB5AeB8671925/<tokenID>

• For assets minted in the Polygon public contract, the asset can be viewed at: https://apps.klaos.io/asset/137/0x30ebd8d3e9b5b303d2b0a81c5cc0ce90ff185e9c/<tokenID>
