Artifact & Artifact Collection

Artifacts are collections of NFTs which are currently deployed to Polygon. They can be thought of badges which are awarded to recipients for completion of tasks.

An artifact can be one of the following...

1. Transferrable ERC1155
2. Non-transferrable ERC1155
3. Transferrable ERC721
4. Non-transferrable ERC721

Here's a link that highlights ERC721 vs ERC1155.

In general, ERC721 token IDs are unique and can only have 1 owner at a time while ERC1155 can have multiple owners for the same token ID.
