# System Architecture

The architecture will consist of the **frontend**, **middleware**, and **blockchain backend**, providing a robust infrastructure that can scale and support future funding rounds.

#### 3.1 Frontend (ICO Page and In-App Management)

* **User Interface:** The ICO page will be inspired by successful ICOs (e.g., Solana, Polkadot) with a responsive design that works across desktop and mobile platforms.
* **Cross-Platform:** Optimize for both desktop and mobile devices.
* **Future Rounds:** The frontend is designed to be flexible and capable of handling future investment rounds with ease.

#### 3.2 Middleware

* **Functionality:** Middleware will manage the interaction between the frontend, blockchain backend, and Web3auth.
* **Wallet Management:** Handle wallet authentication and conversion of **In-App KCs** to **Crypto KCs**.
* **Real-Time Gas Fees:** Integrate a gas price oracle for real-time fee estimation.
* **Scalability for Future Rounds:** The middleware is built to scale, supporting future rounds with minimal changes.

#### 3.3 Blockchain Backend

* **ERC-20 Token on Ethereum:** **Crypto KCs** will be issued as ERC-20 tokens on Ethereum.
  * **Minting and Vesting Contracts:** A total of 1 trillion tokens will be minted, with 75% time-locked for release over 5 years.
  * **Platform Fees:** Apply the **3% platform fee** to all transactions involving **Crypto KCs**.
* **Reusable for Future Rounds:** The smart contracts will be designed to accommodate future token distributions and vesting for new investors.
