Building NFTs represent each backer’s membership and contribution level within the Co-op. They are the source of Daily Backing Points (BP), enabling ongoing participation in project support and minting activities.

#### Building Types:

* <mark style="background-color:blue;">**Mini Building (Base)**</mark>: Generates a small amount of daily BP, ideal for casual participants or newcomers.
* <mark style="background-color:green;">**Main Building (Mainnet)**</mark>: Offers higher BP output, suited for committed backers looking to scale their support power.

#### Differences between Main and Mini Building NFTs:

#### Core Mechanics:

* Minting a Mini Building locks HUNT into its bonding curve pool (or directly into the Townhall contract for the Main Building).
* The more Buildings you own, the more Daily BP you receive.
* Buildings can be burned to unlock HUNT, though doing so reduces your future BP generation.

Buildings transform backers into long-term stakeholders by tying their influence and rewards directly to the growth of the Co-op economy.
