# Key Participants and Their Roles

**Investor**<br>

* Invests USDT in crowdinvesting; if they do not already have it, they can acquire it through a third-party exchange service connected to the platform (CEX/DEX).
* Upon successful funding, receives an NFT that confirms their share (or right to a portion of the revenue) in the future game.
* Can request a partial refund if the developer fails to fulfill their obligations (project halt or failure).

**Crowdinvesting Smart Contract**<br>

* Accepts USDT from investors and locks it during the game development phase.
* Releases funds (in full or part) as milestones are achieved.
* Mints NFT tokens and sends them to investors’ wallet addresses.
* Distributes funds to developers in tranches upon milestone completion (up to 95% of the total raised amount).
* In case of failure, refunds the funds (or remaining balance) to investors and/or activates the insurance fund.

**Game Developer**<br>

* Receives USDT tokens in tranches as they meet milestones (95% of the collected investor funds). These can be sold (if needed) or staked.
* Pays investors a predetermined share of the revenue (e.g., 20–30% of game sales), or provides investors with NFTs.
* If they fail to meet obligations, fund transfers stop, and investors may be compensated through the insurance fund.

**Payment Service**<br>

* Accepts fiat currencies (USD, EUR, etc.) from players or popular cryptocurrencies (BTC, ETH) and converts them into USDT if needed.
* Transfers funds to the platform's balance (centralized accounting system), where they are tracked and can be used by developers/players.
* Processes purchases within the ecosystem, ensuring users can buy Nudix tokens or other in-game assets.

**Credit Module**<br>

* Developers can take USDT loans on the platform by providing Nudix tokens or Intellectual Property as collateral.
* This is not a key feature at launch but can be expanded later as liquidity and demand grow.

**Platform (Centralized Accounting System)**<br>

* The core of the project, managing transactions, balances, withdrawal requests, and more.
* Collects a 5% fee from crowdinvesting to fill the insurance fund.
* Withdrawal requests are processed within 2–3 days.
* Integrates with external payment services to convert fiat or crypto into desired assets.

**SBT Game Minting Smart Contract**<br>

* Issues SBT (Soulbound Token) on request (or automatically) for users:
  * Acts as a "key" to the game.
  * Confirms KYC completion or adult age verification.
* Can also issue NFTs instead of SBT for limited editions with resale rights.

**Player/User**<br>

* May interact indirectly with Nudix tokens since games are purchased through payment services (fiat, BTC, etc.).
* Receives SBT/NFT as proof of ownership or access to adult content.
* Can request withdrawals for in-game earnings or referral income within 2–3 days.
* May purchase Nudix tokens externally to become an investor or participate in additional activities (staking, lending).

**Progressive Staking System**<br>

* The platform features a staking system for Nudix token holders, offering progressive tier levels.
* The longer and larger the staking commitment, the higher the user's status and rewards.
* A portion of the tokens is removed from circulation due to staking, helping stabilize the token's price through constant demand.
* Staking rewards are paid from special platform funds and may be adjusted based on market conditions.
