# NFT Card Auto-Mining

#### A total of 5 NFT Cards with rare attributes are eligible for SDAO mining, no pledge is required and the address will automatically be mining for SDAO Token as it holds a rare NFT Cards

#### [<mark style="color:blue;">By destroy SDAO, the mining computing power can be increased by an additional 1 times</mark>](/sdao/sdao-labs-v2/sdao-empowerment.md)

## 5 NFT Cards with rare attributes :

#### <mark style="color:purple;">**S Rank NFT**</mark> <mark style="color:purple;"></mark><mark style="color:purple;">Card</mark> **=** Opened via NFT blind box

Opened via NFT blind box,with an S mining computing power of 1.

#### <mark style="color:purple;">**N Rank NFT**</mark> <mark style="color:purple;"></mark><mark style="color:purple;">Card</mark> **=** Opened via NFT blind box

Opened via NFT blind box,with an N mining computing power of 2.

#### <mark style="color:purple;">**R Rank NFT**</mark> <mark style="color:purple;"></mark><mark style="color:purple;">Card</mark> **= Destruction of 2 S-rank NFT Card + Destruction of 1 N-rank NFT Card**&#x20;

When a Level 1 address holds ≥ 6 N-rank NFT Card, destroy 2 S-rank NFT Card + destroy 1 N-rank NFT Card to automatically synthesize a new R-rank rare NFT Card with an R mining computing power of 6.**（Limited to 3,000）**

#### <mark style="color:purple;">**SR Rank NFT**</mark> <mark style="color:purple;"></mark><mark style="color:purple;">Card</mark> **= Destruction of 2 S-rank NFT Card + Destruction of 1 R-rank NFT Card**

When a Level 1 address holds ≥ 6 R-rank NFT Card, destroy 2 S-rank NFT Card + destroy 1 R-rank NFT Card to automatically synthesize a new SR-rank rare NFT Card with an SR mining computing power of 24.**（Limited to 1,000）**

#### <mark style="color:purple;">**SSR Rank NFT**</mark> <mark style="color:purple;"></mark><mark style="color:purple;">Card</mark> **= Destruction of 2 S-rank NFT Card + Destruction of 1 SR-rank NFT Card**

When a Level 1 address holds ≥ 6 SR-rank NFT Card, destroy 2 S-rank NFT Card + destroy 1 SR-rank NFT Card to automatically synthesize a new SSR-rank rare NFT Card with an SSR mining computing power of 120.**（Limited to 300）**

## <mark style="color:purple;">Each NFT holding of arithmetic power will be subject to a 50% yield reduction for every interval of ≥ 168 hours that is triggered</mark>

### <mark style="color:purple;">Trigger conditions for production cuts +Automatic SDAO collection:</mark>

* <mark style="color:purple;">Make NFT transfers</mark>
* <mark style="color:purple;">Receive mined SDAO tokens</mark>

{% hint style="info" %}

#### A single address can hold a maximum of 50 NFT Cards with different rare attributes, with different NFTs having different computing power, stacked with the total computing power to calculate mining.
