'Kainos' is a next-generation platform that integrates multiple trading functions in decentralized finance (DeFi). Implementing an original on-chain order book on the Solana blockchain, it provides various financial and entertainment functions, including perpetual futures trading, from a single interface.

1. Background of Development Support for this Platform

In our 'Long-term Vision and Medium-term Management Plan' announced in February 2025, we set forth the construction of a unique ecosystem centered on 'Meme x RWAfi'.

To realize this vision, we believe a mechanism that integrates token trading, liquidity provision, and community engagement into a single platform, consolidating the entire ecosystem's liquidity into one point, is essential. Thus, we have supported the development of Kainos.

2. Introduction of Main Features

Kainos is designed to aggregate liquidity from a wide range of users through its proprietary on-chain infrastructure.

Perpetual Trading (Perpetual Futures)

Provides leverage trading denominated in USDC. It builds a proprietary on-chain Central Limit Order Book (CLOB) and supports limit and market orders. Proprietary Order Book Support (Up to 2x Leverage): GYAN BLUE ($NYAN), Wowbit (WWB) External Liquidity Integration Support (Up to 50x Leverage): SOL, BTC, ETH, BONK, WIF, JUP, ORCA, RAY, JTO, PYTH (10 tokens total)

Liquidity Provision (Earn) Function

A system where users provide assets to the platform's liquidity pool and earn a portion of the trading fees as revenue.

Gamification Functions

Integrates engagement functions beyond trading, such as a price prediction mini-game (Tap Trading) and 1v1 user prediction battles (1v1 Battle).

3. Business Structure and Our Position

The business entity of this product is a corporation located in the United Arab Emirates (Dubai) (hereinafter 'Dubai Corporation'). The Company is involved in this product based on an anonymous partnership agreement concluded with the Dubai Corporation.

The Company stands in a position to provide support such as technical development, business development, and marketing to the Dubai Corporation, and is not the operating entity of this product.
