# Stakable NFTs

In order for NFT to be stakable in Heavenland, it must be first registered for the staking. Only some NFT collections have been selected for staking and this Section shows their overview. Here is the overview of calculations of cNFT for all the stakable NFTs, divided to DAO (staking HTO on these NFT classes grants DAO votes) and non-DAO.
Heavenland will introduce new stakable NFT classes in the future.

## DAO

As a rule of thumb, these NFTs represent some property in Heavenland. The bigger the property, the bigger the
$c_{NFT}$
.

### Parcels

Each Parcel has a
$c_{NFT} = (height_{max}+ depth_{max}) \cdot c_p,$
where
$height_{max} + depth_{max}$
is the sum of max height and depth to which it can be built on the Parcel, and
$c_p$
is the Parcel multiplicator. In the case that the Parcel allows drilling through the Tubus,
$c_p = 1.5$
; otherwise,
$c_p = 1.0$
.

### Parcel Buckets

Parcel merging increases
$height_{max}$
and
$depth_{max}$
, so
$c_{NFT} = (height_{max} + depth_{max}) \cdot (n_p + 0.5 \cdot n_{dt}),$
where
$height_{max} + depth_{max}$
is the sum of max height and depth to which it can be built on the Parcel Bucket,
$n_p$
is the number of Parcels in the Parcel Bucket, and
$n_{dt}$
is the number of Parcels in the Parcel Bucket allowing drilling through the Tubus.

### Solamids

Solamids are another stakable asset with
$c_{NFT}$
calculated from weight w, determined by the Room Size [S: 1, M: 1.2, L: 1.5, XL: 2], and from
$\Sigma_{floor}w$
which is a sum of all weights for all the Solamids on a given floor, as
$c_{NFT} = 4000 \cdot \frac{w}{\Sigma_{floor}w}$

### MetaCity

MetaCity has shown its determination to build in Heavenland and is another stakable asset with
$c_{NFT}$
derived from their Tiers attribute value as
$c_{NFT}= \begin{cases} 30, & \text{if Tiers}=3 \\ 45, & \text{if Tiers}=2 \\ 60, & \text{if Tiers}=1 \end{cases}$

## non-DAO

### Solanauts

Solanauts are another stakable asset with
$c_{NFT}$
calculated from weight w, determined by the Rank Patch [Scout: 1, Explorer: 1.2, SOLdier: 1.4, Captain: 1.6, Commander: 1.8, Solana: 2] and Special Patch (if it has value of Solana, w is increased by 2), and from
$\Sigma w$
which is the sum of all weights for all the Solanauts, as
$c_{NFT} = 10000 \cdot \frac{w}{\Sigma w}$
