# Kondux 3D Marketplace

#### A Dynamic Asset Exchange Framework  <a href="#id-0-toc-title" id="id-0-toc-title"></a>

**Overview**\
The Kondux Marketplace provides infrastructure for transaction, leasing, and utility-layer interaction of dynamic NFTs (kNFTs). It supports extended NFT functionality including DNA-based attributes, role-based access control, and modular monetization features, all secured through smart contracts and interoperable with external systems via the DAB protocol.

***

#### Core Capabilities <a href="#id-1-toc-title" id="id-1-toc-title"></a>

**1. Expanded Transaction Models**

* **Standard Exchange Support**: Users can buy and sell kNFTs through direct listings or auction mechanics.
* **Leasing Framework**: Time-bound leasing of kNFTs with enforced expiration via smart contracts. Applicable to in-game items, subscription assets, or access tokens.
* **Trait-Aware Pricing**: kNFT valuation can be based on live attributes derived from the asset’s DNA, enabling dynamic pricing models.
* **Subscription Mechanics**: Optional recurring access to kNFT-gated features or media via renewable token states.

**2. Monetization & Royalties**

* **Automated On-Chain Royalties**: Enforced through ERC-2981-compatible contracts; royalties triggered at resale with distribution to defined stakeholders.
* **Multi-Beneficiary Splits**: Custom royalty trees allow for multi-party distribution logic for collaborative or licensed works.
* **Usage-Based Revenue**: Revenue mechanisms can tie into asset use metrics, access patterns, or feature unlocks.

**3. Multi-Platform and Interoperable Access**

* **Engine-Agnostic Integration**: Assets can be used across supported 3D environments (Unity, Unreal, Omniverse).
* **DAB Integration**: Enables off-chain validation and token-gated access in Web2 environments.
* **Cross-Chain Roadmap**: Future support planned for cross-chain listing and settlement across EVM-compatible networks.

**4. Security and Access Controls**

* **Smart Contract Enforcement**: All transactions executed trustlessly with validation via on-chain rulesets.
* **Wallet-Based Authentication**: Secure session validation using DAB architecture; ensures verified ownership prior to asset transfer.
* **Immutable History**: All asset activity (purchase, transfer, lease) is stored permanently on-chain.
* **Access Control Lists**: Listings and features can be restricted based on token ownership (e.g., governance tokens, Founder’s Pass, kNFT traits).

#### Example Use Cases <a href="#id-2-toc-title" id="id-2-toc-title"></a>

| User Type               | Functions Enabled                                                                 |
| ----------------------- | --------------------------------------------------------------------------------- |
| **Creators**            | List and sell dynamic art; define royalties; lease time-locked experiences        |
| **Game Studios**        | Issue interactive or upgradable in-game items; rent assets; integrate asset logic |
| **Brands / Businesses** | Token-gated membership or content; authenticated collectibles; licensing          |
| **Collectors**          | Acquire and manage evolving NFT assets with utility and long-term ownership data  |

***

#### Infrastructure & Technical Stack <a href="#id-3-toc-title" id="id-3-toc-title"></a>

* **Contracts**: ERC-721 (kNFT), ERC-2981 (royalty), and proprietary leasing logic.
* **Security**: Role-based access controls, time-locked leases, immutable metadata via on-chain DNA reference.
* **Interfacing**: REST and WebSocket APIs under development for external application use.
* **Frontend**: Web3-enabled interface with direct wallet integration, metadata viewer, and streaming preview via Kondux Viewport.

***

#### Future Enhancements <a href="#id-4-toc-title" id="id-4-toc-title"></a>

* **Cross-Chain Interoperability**: Asset registration and listing across multiple EVM chains.
* **SDKs**: Marketplace SDKs for engine integration (Unity, Unreal) and Web2 bridge modules.
* **Off-Chain Licensing Extensions**: Smart contract wrappers for external asset usage under signed terms.<br>
