# Deadalus

A fractional asset protocol on Starknet.

<!-- ## Questions (Philip)
- What is what we want to build exactly? (an exchange for trading real estate, a voting/maintenance platfrom, the tokenstandard/protocol, sale platform, all of it?) Maybe focus on one? The rest into roadmap?
- For this hackerhouse, I propose we focus on the core logic for fractionalization of the tokenized real world asset and probably voting and maintenance if time permits ( I am already working on a highlevel systems diagram for this ). My goal is to complete the revamped frontend prototype before we get to Denver so we can primarily focus on the core contracts.

- What would be our customers (real estate companies which want to market/sell their projects?, individuals who come together and want to buy one flat?, etc?)
- We find a sweet spot between real estate companies and individuals.

- How to make a sure a share of a flat is legally binding? How does it work with the notary? (legal wrapping)
- Deadalus will be a parent company with legal rights to the company and KYC members have a contract agreement with Deadalus = Deadalus handles the legal wrapping.

- What kind of KYC do you want to use?
- We will need a 3rd party KYC provider to stay in compliance with AML policies, then we can whitelist individuals who pass KYC for the protocol.

- Why ERC721 and not ERC1155? Latest tech? Maybe there is a newer one? https://www.leewayhertz.com/erc-20-vs-erc-721-vs-erc-1155/#:~:text=ERC%2D1155%20can%20perform%20the,%2C%20ICOs%2C%20and%20so%20on
- Yes, ERC1155 is what I am describing, although this hasn't been implimented in Cairo OpenZeppelin yet, but we can potential create out custom version. -->

## Idea Description
We want to create a new platform which transforms how on-chain assets (NFTs) are owned and used. This platform will allow NFT holders to fractionalize their assets and assign unique functionalities to each fraction. For instance, an in-game asset, like a skin, could be divided into seven NFTs, with each NFT granting the owner access to the asset on a specific day of the week. This approach is ideal for users who engage with the game on particular days, such as someone who plays only on Mondays.

A central aspect of the platform is its interoperability with the StarkNet ecosystem. It allows for fractional NFTs to be actively traded on NFT marketplaces and to be utilized as collateral.

In the future this platform could be rolled out even the real world assets.

### Use Cases:
- Time-share, e.g. on-chain game asset (see example above)
- Account sharing, e.g. NFT is access token
- Profit sharing, e.g. NFT is supplied to lending/borrowing platform

### Business Model:
- Customers: players who are willing to share their in-game assets with other players
- Partnerships: partnerships with game studios with which we can define the functionalities the fractions should have
- Revenue streams: plan is to take a creator fee of 5% of the value when the fractions are created and another 5% of the value when the NFTs are traded (half these rewards should flow back to the original creators of the on-chain assets) - exact numbers can be defined later

### Technical Implementation
#### Front-end functionality
1. Vault which holds the NFT
2. Functionality which fractionalize the NFT with inscribed features
3. Overview of all the different fractions/shares with attributes
4. Redeem function (tbd. define a logic how to release NFTs out of the vault, maybe voting mechanism)
5. Integration with DEX, Lending/Borrowing platform

#### Smart contracts
- Tokenstandard (like ERC 1155)
- Integration with game studio contracts
- ... tbd

<!-- ## Idea Description

The goal of this project is to design a protocol that enables real world real estate assets to be represented and traded in fractional portions on Starknet, a permissionless decentralized rollup optimized for scalability and provable computation.

The protocol will allow asset originators to tokenize full ownership of a property by creating an ERC-721 non-fungible token bound to the asset through a legal wrapping. This parent NFT can then be split into fractional ERC-20 tokens through a standard we will develop called Real Estate Asset Fractional Tokens (REATs).

The REAT standard will have properties like address of the original asset, percentage ownership of the property the tokens represent, and binding legal documentation references. REATs can be freely traded on a primary decentralized exchange by KYCed individuals.

There will be a portal for accredited investors to purchase REATs after undergoing KYC. The protocol will have a REAT governance contract to distribute rental yield, handle maintenance votes, and allow REAT holders to trade their tokens. There will also be liquidity rewards for providing two-sided markets for REAT tokens.

The protocol will handle property appraisals, disputes, and maintenance in a decentralized governance system encoded into smart contracts. Oracle services can enable real world data like rental yields to be used in the on-chain governance and incentive systems.

This brings more liquidity for real estate as an asset class, lower barrier to entry for investors, automated management and rental distribution, and transparency using Starknet security and scalability. -->

## Milestones covered during the Hacker House duration
- Design token standards ERC 1155 for Cairo
- Code core smart contracts (NFT Vault, Fractionalization logic, ...) audited by Starknet HackerHouse experts
- Integration with a Starknet game (tbd.)
- Working UI
- Challenged business model for further development and go-to-market
- Documenation of the code base

<!-- - Parent ERC-721 NFT
- Child ERC-20 Fractional Tokens
- ERC-721 NFT minting
- ERC-20 Fractional Token minting -->

<!-- ## Business model -->

<!-- A hybrid model likely makes sense - combining recurring SaaS platform and data fees along with transaction fees and liquidity incentives. -->

<!-- 2. Asset Originator Fees
Charge real estate asset originators a listing fee to add their properties to the protocol and investor portal. Can charge recurring access fees. -->
<!-- 3. Investment Platform Fees
Build a fractional real estate investment platform and charge investors subscription and transaction fees to purchase fractionalized property tokens.
4. Licensing Model
Develop proprietary legal, compliance, token standards and charge other startups/platforms a fee to license the protocol stack. Can charge ongoing branding/affiliation fees.
5. Data Monetization
Aggregate data on property appreciation, rental yields etc. Can sell access to this data to investment firms, researchers and banks.
6. Decentralized Finance
Generate yield through provision of decentralized lending, market making or staking functions -->
