Blueprints are NFTs that allow the holder to craft a corresponding Equipable Item. They are held on-chain in your wallet and can be traded on the Chikn marketplace.

Rarer Blueprints either create rarer Items or result in more items crafted in a single event.

Some Items have a limited global supply. <mark style="color:red;">Once the global supply cap is reached, players won’t be able to craft any more of that Item and must instead purchase them from the secondary market.</mark> The total supply of each Blueprint is 10% of the maximum supply of the Item it can craft (which is counted across both on-chain and off-chain Items). See [Items](/gaming/foraging/items.md) for more information on this cap.

There’s no limit to the number of times you can craft from a Blueprint, as long as the Item supply cap hasn’t been reached.

Blueprints are discovered as you dig through your WormFarm. Once a Blueprint is found, you’ll need to fill your WormFarm with $WORM to the depth of the Blueprint in order to recover it.
