# Summary
I, LevX, proposed the idea of our [NFT exchange](https://forum.sushi.com/t/natto-sushi-nft-exchange/3475) and thanks to our passionate community members, especially @FutureFund, it evolved into a concrete project that would meet the actual needs of NFT artists & collectors.

Now that [contracts are complete](https://github.com/sushiswap/shoyu/), it's time to develop frontend, caching layer(subgraph) and infrastructure for artworks storage. Around mid August, v0 will be released and we have gradual release plans for v1 and v2 for the next few months.

As the product manager & lead developer of Shoyu, I'll guarantee the release of v0, further(v1 & v2) updates and maintenance in the next 1 year.

# Motivation

# Features

## 1 Gallery
### 1.1 Immersive Display
To provide Sushi and Shoyu users with a diversified platform, we are incorporating multiple immersive gallery and auction modes to satisfy both our future NFT minters and collectors. These will be customizable and shy away from the average chronological grid format of all of the current NFT sales platforms available today.

### 1.2 3D Metaverse
Despite the best efforts of even the most talented of developers, the Metaverse still seems a long way away from the smooth and seamless experience that we demand from most of our technology this day and age. This will no longer be the case, as our 3D gallery, auction and Metaverse SushiBar are in development to provide the digital serenity you so seek.

## 2 Social Token

`SocialToken` s are built around an “ownership economy” principle with the premise that a community will be more valuable tomorrow than today. Creators can monetize their work as a non-fungible token (NFT) or social token, and supporters can give something back to show their loyalty.

### 2.1 Minting

Owner of the social token can mint a certain amount of tokens for an account, proportional to the contribution he's committed. The amount of the contribution will be observed off-chain by the owner.

### 2.2 Burning

Any holder of the social token can burn his/her own balance with a memo( `bytes32` ). This can be used for a variety of scenarios such as **a. burn-and-enter** , **b. burn-and-receive** or **c. burn-and-draw** .

* **burn-and-enter** : Users burn their tokens and get the entrance permission to a gallery, exhibition or a concert.
* **burn-and-receive** : Users burn their tokens and leave their address. Then the artist delivers the merch or the product to their front door.
* **burn-and-draw** : Users burn their tokens and get a lottery ticket. It can be designed such that the more he burns, the higher the chance to win the lottery.

### 2.3 Revenue Sharing

As an artist or a seller, the owner of the social token can make revenue and set the recipient to the holders of the social token. The revenue will then be distributed to the holders in proportion to the shares. 

## 3 NFT-as-Exchange
Shoyu's `ERC-721` and `ERC-1155` contracts are equipped with NFT exchange functionality in themselves(`NFT721` and `NFT1155` respectively). This is the cheapest way to optimize gas and give the owner the full power to change configs needed for trades.

### 3.1 On-chain & Off-chain OrderBook
To optimize gas cost when submitting sell order, orders are kept off-chain basically. When an account wants to buy the nft, he can pick the order with the maker's signature(`ERC-712`) and execute it with a proper bid params such as the price.

It also supports on-chain order book, so you could submit ask orders. This feature was designed for contracts not EOAs. *e.g.) If you're running a dao for NFTs, then contracts should be able to submit orders.*

We'll use off-chain order book for Ethereum and on-chain one for Polygon, initially.

### 3.2 Variant Bidding Strategies
Strategies are separate from exchange contracts, so a variety of strategies can be plugged in to meet the seller's demand. Supported strategies are: a. `FixedPriceSale`, b. `EnglishAuction` and c. `DutchAuction`.

* **Fixed Price Sale**: The first buyer who pays for the fixed price gets the NFT.
  
* **English Auction**: An English auction is a process in which an asset is sold through a suggested opening bid reserve or a starting price that is set by the seller. Increasingly higher bids are accepted from the gamut of buyers. Ultimately, the price is adjusted in a direction that's unfavorable to the bidders.
  
* **Dutch Auction**: A Dutch auction is a market structure in which the price of something offered is determined after taking in all bids to arrive at the highest price at which the total offering can be sold. In this type of auction, investors place a bid for the amount they are willing to buy in terms of quantity and price.

### 3.3 Royalties Distribution
NFT royalties give the owner a percentage of the sale price each time their NFT creation is sold on Shoyu. They can choose their royalty percentage(0-25%).

### 3.4 NFT Tagging
NFTs can be categorised and tagged to allow better searching capabilities.

## 4 Fractional NFT Ownership & Governance
Fractional ownership allows users who have been previously priced out of certain NFTs or artists (such as Beeple) to be able to buy a piece of their work.

### 4.1 Liquidation
If you're holding a `NFT721` token, you can call `liquidate()` function to turn your nft to a `NFT721GovernanceToken` (`ERC-20`) that's representing the value of your nft.

### 4.2 Governance
Token holders can vote for a sell proposal to run the NFT governance. If more than `minimumQuorum` balance power is for the proposal that were submitted, then it starts selling process; It could be an auction for a fixed price sale.

### 4.3 Profit Sharing
After the sale gets completed, the profit is shared by the owners in proportional to their balances.

## 5 Fee & etc.
### 5.1 Fee Structure
* **Protocol Fee**: 2.5% of every trade goes to xSUSHI holders
* **Operational Fee**: 0.5-2.0%(TBD) of every trade goes to operational funds
  - cover ethereum tx fees
  - cover infrastructure pricing(image/video hosting) 
  - help support art projects that will create a significant impact to artistry
* **Royalties**: x% of every trade(25% max, set by the minter) goes to the original minter
* **Charity**: artists can choose to set recipient of the revenue as 'charity fund' managed by Sushi Shoyu op-multisig

### 5.2 Mutichain Support
Artists can mint and sell their NFTs on **Ethereum** or **Polygon**. NFTs can be transferred between two chains with no hussle.

## 6 Security
All contracts are scheduled to be audited by Peckshield, Mixbytes and Zokyo.

# Compensation

I'll take full responsibilty as the product manager/main dev of Shoyu and I guarantee further updates and maintenance for the next 1 year.

Since [my transition from a core dev to a contributor](https://twitter.com/LevxApp/status/1399770031039332353?s=20) last month, I've been working on Shoyu contracts without getting payed.

I'd like to request the dev & maintenance fee of 35k SUSHI in sablier for 1 year, which is 12.5% of my old 1-year wage when I was a core dev. Core team can cut off my stream whenever they think I'm not delivering my promise.
