# SpaceFi Intro

<figure><img src="/files/UH2eaOUWelbOt07VjahK" alt=""><figcaption></figcaption></figure>

On November 1st, 2008, Satoshi Nakamoto introduced the concept of Bitcoin. Since then, crypto world has been flourished. We are a group of crypto enthusiasts from different cultures and backgrounds around the world, who want to launch a widely participatory crypto experiment. Diving into crypto, just as exploring space. So, we name it SpaceFi.

SpaceFi is the DeFi hub on zk-Rollups with DEX+NFT+Spacebase+Launchpad, exploring the Layer2 ecosystem.

SpaceFi is deployed on zkSync Era now, and also runs separately on Evmos as an exploration in Cosmos ecosystem.

**zkSync** is a Layer 2 scaling solution on Ethereum that offers low gas and fast transactions, without compromising on security. It’s a scaling and privacy engine for Ethereum, based on zero-knowledge proof technology.

**Evmos** is the EVM hub on Cosmos. It will not only bring EVM developers into Cosmos eco, but also works with Celestia to bring modular and interoperable cross-chain solutions to EVM ecosystem.

## **Products**

Space has created a fully integrated system that strives to create sustainable chemistry between the products. In the Space universe, you can earn DeFi rewards through liquidity mining, trading mining or minting SPACE tokens into NFTs for higher revenue, transaction fee dividends, premium trading, and governance rights, etc. At the same time, you can also create a Spacebase, invite fans and friends to join, both sides get additional rewards. Space will also be on the Starter platform to incubate and support outstanding ecological projects, and jointly build Space.

### 1. Decentralized trading platform: SpaceSwap

* **Low fees and efficient**&#x20;

Space runs on zk-Rollups, with low transaction costs and faster transaction speed.

* **Cross-chain ecosystem**

Space is multichain deployed and will be a bridge among layer1 ecosystems.

* **Multiple Value Capture**

SpaceSwap transaction fee will be used for LP rewards, buyback-and-burn, NFTs dividends, etc. Traders can also receive transaction fee mining rewards.

### 2. Mining Rewards

* **Farm**

By staking single coin and LPs in the Farm, you can get mining rewards. Staking NFTs will give you even higher mining rewards.

* **Transaction Fee Mining**

By using SpaceSwap, you can also get additional transaction fee mining rewards, even much higher than the fees themselves.

### 3. NFT System

* **NFT Minting**

Space NFT is not just a collection, but a set of NFT systems with strict token mechanism design. With SPACE tokens, you can mint primary NFTs, and combine multiple NFTs to mint higher level NFTs.

* **Bonus, Staking and Marketplace**

As an NFT holder, you can earn Space multiple transaction fee dividends. Staking NFTs for mining will also give you higher rewards. You can sell NFTs on the market and earn high premiums.

### 4. Starter

Starter is Space's incubation and fundraising platform. You can use SPACE tokens to participate in the early-stage investment of quality projects.

### 5. Spacebase

Spacebase is Space's on-chain community, create or join Space Base to earn more mining rewards. Groups can participate in base PK to get special honors and rewards.

## **Project Feature**

### **A more scientific and comprehensive token system**

Compared to other trading platform or NFT projects, Space has a more scientific token system that greatly enhances sustainability.

* Liquidity mining for market makers, transaction fee mining for traders, a comprehensive combination of the two, which facilitates the development of user habits and Space's early start-up.
* Space's token system has an NFT system in addition to the core token SPACE. From fungible tokens to non-fungible tokens, the process of producing fungible tokens makes the entire token system more dynamic.
* The Starter platform allows SPACE holders to get investment opportunities in quality projects, while quality projects can attract new users and diversify values into the Space ecology.

### **A practical and valuable NFT system**

In the Space universe, NFT is no longer a gimmick or a speculative tool, but a system of value with a rigorous token mechanism. NFT has a rich variety of categories and different functions, as well as the ability to combine and upgrade, and other scenarios yet to be unveiled. Whether you are a newcomer to NFT or a veteran of trading and collecting NFTs, there is ample room for experimentation.

### **On-chain community with fission propagation**

SpaceBase quickly maps off-chain communities to on-chain through fission propagation, which not only promotes communication among users, but also can stimulates more vitality and value through activities like base PK.

### **A colorful and evolving ecology**

Space is not just a trading platform or a place to trade and use NFT, it is a vast world, a metaverse in the early stages of construction, with more features to be developed. The tokens or NFTs you hold may have a new value in the next board that opens up.


# Community Governance

![](/files/B8l0NZ54TXMumcb4XgkB)

Space belongs to all members of the community. The participation, support and enthusiasm of the community determines the ultimate look and size of the Space world. Of course, Space will reward the community with growth. Because of this:

### **Dedicated DAO treasury**

A certain percentage of the token emission goes into a locked DAO treasury as a reserve for future project development and strategic cooperation, to be used and allocated by community governance.

### **Community Resolution**

After the smooth operation of Space, community governance will be carried out gradually. The initial phase will be promoted by the team, and the subsequent proposals will be initiated and voted on by way of Snapshot, and then Space will be governed by a more standardized DAO.

Troubleshooting errors and General FAQ

### &#x31;**.Issues on swap: insuffcient fee**

<div align="left"><figure><img src="/files/xFr3juk0KDYXijgAu4Sf" alt=""><figcaption></figcaption></figure></div>

#### <mark style="color:blue;">Solution</mark>

About Max Gas Issue: Some spacers may have Max Gas Issue in Metamask which may cause it exceed the balance and failures. The main reason is the gas fee setting issue in 'Advanced gas controls'. You can try the following methods to fix it: Method

A: You can close the 'Advanced gas controls' (Metamask > Setting > Advanced). Method

B: Keep the 'Advanced gas controls' open and edit the gas parameters. And uncheck the box 'Save these new values as my default for Advanced'. Max base fee: 0.25

Max priority fee: 0.25

Gas limit: 3295043 (or higher if needed)

# Trading

![](/files/mf4r2UHHNgQhDaEWR9YS)

## **Trading**

SpaceSwap is an exchange with an Automated Market Maker (AMM) that offers low rates and efficient decentralized trading where you can trade or provide liquidity for profit.

&#x20;

## **Decentralized trading**

Everything you do on SpaceSwap is routed directly through your own wallet, no need to trust someone else with your coins.

&#x20;

## Liquidity Pools

By adding liquidity to SpaceSwap, you will receive LP tokens as reward. When users swap, you earn the LP tokens for the trading fee rewards.

&#x20;

## **Allocation of trading fees**

When you trade with SpaceSwap, you pay 0.3% of trading fee, which is allocated as follows.

0.15% - directly allocated to the liquidity provider

0.05% - buyback and burn SPACE

0.05% - buyback SPACE and allocate to NFT and DAO treasury (70% to NFT for dividends, 30% to DAO lock-up)

0.05% - development and operating funds

&#x20;

## **Liquidity Mining**

Liquidity Mining, also known as Yield Farming, stake your LP tokens to Farm, participate in liquidity mining, and earn SPACE rewards.

&#x20;

## **Trading Mining**

By trading, you can participate in trading mining and earn SPACE rewards based on transaction volume. A percentage of the block rewards is allocated to the trading mining reward pool, allocation is based on your trading volume and the reward weighting of each trading pair.&#x20;

&#x20;

*\* At the early age of SpaceFi's whole launching, trading mining won't be enabled. The trading mining reward allocated by the blocks will be locked in the trading mining reward pool. When trading mining is live, the reward will be partly airdropped to users who have previously traded and partly burned, according the actual trading data.*


# How to trade

1\. Visit the [trading page](https://swap.spacefi.io).&#x20;

![](/files/WD8IZl1VyFW3aRE33een)

2\. Enter the Token name or contract address you want to trade and enter the quantity.

&#x20;![](/files/CoCqHbPhRGMnXKOF5ehD)

3\. Check transaction details and click "Swap".

&#x20;![](/files/D1KoSg651pDDYZ12tYWs)

4\. Confirm the transaction history in your wallet.

&#x20;![](/files/NnNgBe9HHv1PKHdEaPnQ)


# Liquidity Pool

When you add tokens to the liquidity pool, you will earn liquidity pool (LP) tokens and share fee revenue.

&#x20;

### **LP Token**

For example, if you deposit EVMOS and USDC into the liquidity pool, you will receive EVMOS-USDC LP tokens.

The number of LP tokens you receive represents your share of the EVMOS-USDC liquidity pool. You can also redeem funds at any time by removing liquidity funds.

![](/files/gaMi4gW61qPo7vupmogm)

&#x20;

Liquidity providers earn transaction fees

When someone trades with your liquidity pool, you will earn a corresponding fee as a reward. The trader will pay a fee of 0.3%, of which 0.15% will be added to the liquidity pool of the pair they are trading.

For instance:

● 10 LP tokens represent 10 STAR and 10 USDT tokens

● 1 LP token = 1 STAR + 1 USDT

● Someone trades 10 STAR for 10 USDT

● Other people trade 10 STAR for 10 USDT

● STAR/USDT liquidity pool now has 10.015 STAR and 10.015 USDT

● Each LP token is now worth 1.00015 STAR + 1.00015 USDT

&#x20;

To get even more value out of being a liquidity provider, you can also put LP tokens into the Farm to earn more revenue while still receiving the 0.15% transaction fee bonus.

&#x20;

### **Impermanent Loss**

Providing liquidity is not without risk, as you may be exposed to impermanent losses.

&#x20;


# How to add/remove liquidity

# Farm

![](/files/JE67x02tZ1xo4g224Lu0)

With Space farms, you can earn SPACE rewards by staking single coin, LP tokens (liquidity pool), NFTs and etc. Each farm pool has its own APR depending on the value of the staked tokens, the reward weight and the price of SPACE.&#x20;

## **Single Pool**

Stake SPACE, Evmos and other single coins to participate in farming and get SPACE rewards.

## **LP Pool**

Stake LP tokens such as SPACE-EVMOS, SPACE-USDC, etc. to participate in farming and get SPACE rewards.

## **NFT Pool**

Mint and stake different levels of NFT to get higher rewards than regular farming.

*\*\* Some pools may have special rules, for instance, if the staking is withdrawn within 30 days, then 50% of the farming reward is taken as the handling fee. 70% of the handling fee goes into the planet NFT bonus pool, and 30% goes into the DAO treasury lock-up, which is reserved for ecological development.*

# NFT System

![](/files/MS224t35aE8qqrFVpFcF)

## **What is NFT?**

NFT stands for non-fungible token, meaning "heterogeneous token", which is the concept of crypto assets as opposed to FT (homogeneous representative). Common project tokens such as BTC, ETH, and stable coins USDC, USDT, etc. are all FTs. FTs refer to undifferentiated assets, such as currencies, securities, voting rights and etc.

NFTs, on the other hand, refer to assets that are unique and perhaps need to be referred to differently, such as collectibles, props with obvious numbered attributes, differentiated financial interests, etc.

With the development of the crypto world, those assets and interests that cannot be referred to by a uniform label. They need a brand new asset standard to define, and that is the meaning of NFT.

&#x20;

## **Planet NFT**

Planet NFT is a pass in the SpaceFi ecosystem, which carries a large number of assets and interests with differentiated functions and values, and also has more application scenarios in the future Space DAO and Game. The current benefits of NFTs are mainly:

* You can mint Common Planet NFTs, or use Common Planet NFTs to mint Unique Planet and Exclusive STAR Sign NFTs, gaining a 105%-150% multiplier with each minting.
* You can stake Planet NFTs to farm SPACE token, gaining higher rewards than regular farming.
* You can get various bonuses for NFTs holders, including minting fee, trading fee, spacebase fee and validator commision.
* You can sell Planet NFTs to get a premium for scarcity.
* You can use Planet NFTs to post proposals and vote, when SpaceFi governance is launched.

Space World has a variety of different functions and values of NFTs, initially issued as a set of planetary NFTs, as follows:

&#x20;

### **Common Planet NFT：Primary**

#### STAR >>> Common Planet NFT

* There are 10 types of common planet NFTs, unlimited and randomly generated.
* In the initial minting of common planet NFTs, each NFT requires a certain consumption of SPACE (the number can be adjusted by the project), the minting of 90% SPACE burned, the other 10% SPACE as a handling fee, of which the handling fee of 70% as NFT holders of dividends, 30% into the DAO treasury lockup for ecological development reserves.
* When minting NFTs, different NFTs possess different multiplication factors. Factors for the common planets are as follows:

Galaxy (1.5x)

Nebula (1.45x)

Black hole (1.4x)

Stellar (1.35x)

Planet (1.3x)

Satellite (1.25x)

Asteroid (1.2x)

Comet (1.15x)

Meteor (1.1x)

Meteorite (1.05x)

&#x20;

*\*\* NFTs are equivalent to special multiplier assets. For example, if a galaxy NFT (1.5x) is minted using 2500 SPACE, the equity asset of that galaxy NFT is equal to 2500 \* 1.5, which is, 3750 SPACE. Staking that galaxy NFT to participate in mining will also result in a reward equal to 3750 SPACE mined.*

*\*\* The amount of SPACE required to mint a Common Planet NFT maybe adjusted according to real-time conditions.*

&#x20;

### **Unique Planet NFT：Intermediate**

#### Common Planet NFT >>> Unique Planet NFT

* There are 10 types of Unique Planet NFT, limited to 500 of each, 5000 in total, randomly generated.
* Collecting 9 different types of Common Planet NFTs, you can randomly mint 1 Unique Planet NFT to get different multiplication factors again. Factors for the Unique Planets are as follows:

Sun (1.5x)

Mercury (1.45x)

Venus (1.4x)

Earth (1.35x)

Mars (1.3x)

Jupiter (1.25x)

Saturn (1.2x)

Uranus (1.15x)

Neptune (1.1x)

Moon (1.05x)

&#x20;

*\*\* The equity assets of a Unique Planet NFT are equal to the sum of the equity assets of the first 8 Common Planet NFTs minted multiplied. For example, if a random Venus (1.4x) is minted, using a Galaxy (1.5x, minted with 2500 SPACE), Black hole (1.4x, minted with 2500 SPACE), Stellar (1.35x, minted with 3000 SPACE), Planet (1.3x, minted with 3000 SPACE), Meteor (1.1x, minted with 4000 SPACE), Comet (1.15x, minted with 4000 SPACE), Nebula (1.45x, minted with 4500 SPACE) and Asteriod (1.2x, minted with 5000 SPACE),  the equity asset of that Venus NFT = (1.5\*2500+1.4\*2500+1.35\*3000+1.3\*3000+1.1\*4000+1.15\*4000+1.45\*4500+1.2\*5000)\*1.4=51415 SPACE. Staking that Venus NFT participates in mining and will also be rewarded with the equivalent of 51415 SPACE mining.*

&#x20;

### **Exclusive Star Sign NFT：Advanced**

#### Unique Planet NFT >>> Exclusive Star Sign NFT

* There are 12 types of Exclusive Star Sign NFTs, randomly generated.
* By collecting 5-10 different types of Unique Planet NFTs, you can randomly mint 1 Exclusive Star Sign NFT and again get different multiplication factors. Factors for Exclusive Star Signs are as follows:

Aquarius, Pisces, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius,  Capricorn

&#x20;

Random generation order according to the Exclusive Star Sign NFT:

1st-2nd Star Sign: 2x multiplier, requires 5 different unique planets NFT minting

3rd-4th Star Sign: 3x multiplier, requires 6 different unique planets NFT minting

5th-6th Star Sign: 4x multiplier, requires 7 different unique planets NFT minting

7th-8th Star Sign: 5x multiplier, requires 8 different unique planets NFT minting

9th-10th Star Sign: 6x multiplier, requires 9 different unique planets NFT minting

11th-12th Star Sign: 7x multiplier, requires 10 different unique planets NFT minting

*\*\* For example, if you use three 8-made Unique NFT and two 9-made Unique NFT to mint a 2nd Exclusive SPACE Sign NFT, the assets=(2500x8x3+2500x9x2)x2=210000 SPACE.*

*\*\* This is an initial plan that can be adjusted based on community’s feedback and minting process.*

### **NFT Staking**

Stake NFTs in Farm and you can participate in SPACE mining according to the multiplied equity assets

&#x20;

### **NFT Dividend**

There are various fees in Space, such as minting primary NFTs, Swap transactions, NFT transactions, creating Space Bases, etc. NFT holders can receive Space fee dividends according to the proportion of equity assets.

&#x20;

### **NFT Trading**

You can trade NFTs in Space's NFT market, 5% of the sales will be used as a commission, 70% of which will be used as dividends for NFT holders and 30% will go into the DAO treasury to lock for ecological development reserves.

&#x20;

*\*\* If no NFT has been minted yet, the NFT dividends accumulated during the period will be temporarily locked in the dividend pool. After the first NFT is generated, all previously accumulated dividends will be distributed to the holders of the first NFT. Thereafter, NFT dividends will be distributed immediately in proportion to the respective equity assets.*

### **Other NFT**

There are other types of NFTs in the Space world, with different functions and usage scenarios, so stay tuned.

# Spacebase

![](/files/hKbUosCiorMhecKui9ag)

Spacebase is Space's on-chain community. By creating or joining Spacebase, you can additionally get more mining rewards. Better yet, you can form a group to participate in base PK to get special honors and rewards.

&#x20;

## **Create Spacebase**

To create a Spacebase, you need a certain amount of SPACE (the number will be adjusted). The default is 10 memberships. If you need more places, you can purchase additional places with SPACE. Of the SPACE you pay, 90% will be burned directly and 10% will be used as a handling fee. Of which, 70% of the fee will go into the dividend pool for NFT holders, and 30% will go into the DAO treasury to be locked up for ecological development reserve.

&#x20;

## **Spacebase Bonus**

You can invite fans or friends to join your Spacebase and both of you will receive an additional 5% mining bonus. For example, if A creates a spacebase and invites B, after that B stakes 10,000 USDT assets to mine for 10000 SPACE bonus. Then both A and B will receive an additional 500 SPACE bonus.

&#x20;

## **Spacebase PK**

You can also form a group to participate in Spacebase PK and get special honors and SPACE awards such as TOP Base and Popularity Award according to Spacebase TVL, number of members, etc.

&#x20;

## **Future**

In the future, Spacebases will be upgraded to special NFTs to play. More use scenarios in DAO governance and Space games, so stay tuned.

# SPACE Bridge

<figure><img src="/files/T1fR34RNAonq1lhxpl4y" alt=""><figcaption></figcaption></figure>

SPACE Bridge is specially designed for transferring SPACE/xSPACE/Planet NFT between different chains, currently Evmos and zkSync Era.

[*`According to community discussions, the development of the bridge between zkSyncEra and Evmos is stopped and closed.`*](https://twitter.com/spacefi_io/status/1669365395390623745)

## Transfer Rate

When transferring SPACE/xSPACE, there'll be a bridge fee (5%, adjustable), marked as Transfer Rate, to maintain the balance of different chains. Planet NFT won't.

The token in the original chain will be burned and a corresponding amount of token will be issued in the target chain as native token.

An amount of SPACE will be charged as the gas fee for bridging.

## Burn and Bonus

90% of bridge fee will be burned and 10% will be allocated to NFT Bonus (70%) & DAO (30%) in the original chain.


# Validator (Evmos)

![](/files/B9yC4zZhktyggUEVyXid)

SpaceFi community co-built a validator on Evmos named spacefi.io. We encourage the community to participate in Evmos and zkSync ecosystem building and governance. There’ll be delegator points for stakers, based on staked amount, time and number of voting. [<mark style="color:purple;">**( Space Validator Incentive )**</mark>](https://twitter.com/spacefi_io/status/1536302354495987712)

## [<mark style="color:purple;">**Delegator Center**</mark>](https://validator.spacefi.io/evmos/delegatorcenter)

**What is Delegator Point:**&#x20;

Delegator Points is an evaluation of contribution, based on your staked amount, time and governance participation.

Delegator Points = staked amount A \* A days / 10 + staked amountB \* B days + … + number of voting \* 100

eg. You staked 1000 $EVMOS for 30days, and staked another 500 $EVMOS for 25days. Also, you voted twice on governance.

Your Delegator Points = 1000\*30/10+500\*25/10+2\*100=4450

**Use of Validator Points:**

It can be used in validator incentive such as airdrop, WL and NFT. What's more, some interesting ideas such as delegator NFT, soulbound are in cooking. Let's co-build it.

![](/files/EiuRIBfiFjAQvfMNdKNT)


# For delegators

![](/files/oFRAkWmcQ3UfyrtRVzkr)

**For stakers:** there will be airdrop, WL and medal NFT as incentive.


# For community

![](/files/aKqppELGpYGMrRgX9ETA)

**For SpaceFi community:** 50% of validator commision will be redistributed to planet NFT holders, community contributors, buyback and burning $STAR.


# SPACE TOKEN

![](/files/pk9LQX4T247fOUO6CqIe)

SpaceFi is the DeFi hub on zkSync Era with DEX+NFT+Spacebase+Launchpad, exploring the Layer2 ecosystem. This paper is our initial vision of SpaceFi tokenomics, including thoughts on distribution, incentives and governance, to allocate SPACE tokens to stakeholders most aligned with the strategic direction of SpaceFi.

## **📆 Token Release Schedule** <a href="#id-6050" id="id-6050"></a>

SPACE is the utility and governance token of SpaceFi. The Max Supply of SPACE token is 50M on zkSync Era mainnet, with an initial supply of 10M SPACE at genesis for incentive, IDO and strategic reserves. This will balance early contributor incentives and future development needs to pursue long-term benefits with the community.

The daily emission can be adjusted to match the growth of SpaceFi (current daily emission: about 28,512 xSPACE on 2023.11.30). This will allow SPACE to reach the Max Supply of 50M. When reaching, the community can also decide to increase the emission if needed.

> *\*As an initial distribution plan, the token emission, decay rate and schedule can be adjusted through governance.*

### &#x20;<a href="#id-1dd0" id="id-1dd0"></a>

### **The allocation of new token released** <a href="#id-1dd0" id="id-1dd0"></a>

### **80%, to the community** <a href="#id-1ed5" id="id-1ed5"></a>

* 70%, allocated to mining rewards, for liquidity rewards, staking, trading mining, etc.
* 10%, allocated to DAO treasury, through governance, for ecological construction, strategic cooperation, etc.

> *\*The above ratio can be adjusted to coordinate short-term and long-term interests.*

### **20%, to the dev team** <a href="#id-8e2d" id="id-8e2d"></a>

If certain individuals on the initial development team are no longer part of the network, the community may choose to reclaim any unpublished tokens and redirect them to the new program.

*`The previous adjustments of SpaceFi tokenomics:`*

*`2023.06.15:`* [*`According to community discussions, the development of the bridge between zkSyncEra and Evmos is stopped and closed. The product and token will keep run separately on zkSyncEra and Evmos.`*](https://twitter.com/spacefi_io/status/1669365395390623745)

*`2023.05.06:`* [*`According to community discussions, the Max Supply of $SPACE was cut from 600M to 100M (on zkSyncEra and Evmos).`*](https://twitter.com/spacefi_io/status/1653718494033354753)


# xSPACE TOKEN

xSPACE is a non-transferable escrowed governance token, which is converted by SPACE 1:1 locking with a 30 days unbonding period. If choosing to unbond xSPACE instantly, 50% SPACE will be converted back and the other 50% SPACE will be burned.

It can be earned from farming, or converting SPACE directly. xSPACE can be staked in farm to earn more xSPACE and be used in SpaceFi governance in the future.


# PLANET NFT

[Planet NFT](https://docs.spacefi.io/products/nft-system) is a pass in the SpaceFi ecosystem, containing lots of SPACE assets and different usages. It can be minted by SPACE token (90% burned, and 10% is used as platform fee allocated to NFT bonus and DAO locked). There’re different levels of Planet NFT, including Common Planet minted by SPACE token, Unique Planet minted by different Common Planets and Exclusive STAR Sign minted by different Unique Planets. [(SpaceFi NFT System)](https://docs.spacefi.io/products/nft-system)

Planet NFT holders can post the on-chain proposals. Both Planet NFT holders and xSPACE holders can vote in the governance.


# Emission and Deflation

<figure><img src="/files/XpgWa1rz2KksFnwesMeE" alt=""><figcaption></figcaption></figure>

### **Token emission and deflation** <a href="#id-9502" id="id-9502"></a>

### **Emission:** <a href="#id-23be" id="id-23be"></a>

Distributed by the block, new SPACE will be issued when the farm rewards is harvested. The harvested SPACE will be converted automatically to xSPACE as the reward.

### **Deflation:** <a href="#id-0c3a" id="id-0c3a"></a>

* 10% of the emission of block belongs to DAO, locked and used by community governance.
* 50% of SPACE will be burned if the xSPACE is unbonded instantly.
* 90% of Space Bridge fee (transfer rate) will be burned and 10% will be allocated to NFT Bonus (70%) & DAO (30%) in the original chain.
* 1/3 of the swap fee is used to buy back SPACE, 50% is directly burned and 50% is used as platform fee (70% for NFT bonus and 30% for DAO locked).
* 90% of SPACE paid for minting NFT is directly burned and 10% is used as platform fee (70% for NFT bonus and 30% for DAO locked).
* 5% of the NFT marketplace trading volume is used as platform fee (70% for NFT bonus and 30% for DAO locked).
* 90% of the SPACE paid for creating spacebases or increasing the quota of members will be directly burned and 10% will be used as platform fee (70% for NFT bonus and 30% for DAO locked).
* For some single farm pools, if the rewards is harvested within 30 days, 50% of the rewards will be used as the platform fee (70% for NFT bonus and 30% for DAO locked).
* Using LP tokens to raise funds for the project in Starter, the raised SPACE tokens will be burned.<br>
