Unaxi Technical Documentation

1. Introduction

UnaxiGold (symbol: UXG) is a blockchain-based digital asset designed for the Unaxi fintech ecosystem. The primary network is Polygon, with plans to support BSC (Binance Smart Chain), TRX (TRON), and other popular networks in future phases. The platform provides a centralized exchange (CEX) for buying, redeeming, and managing tokens, supporting multiple cryptocurrencies for purchases (via Oxapay and NOWPayments) and stablecoins (USDT, USDC, DAI) for redemptions. Tokens are dynamically minted during purchases and burned during redemptions. A 3-month pre-sale period offers a guaranteed 5% monthly profit (15% total), with tokens locked until the period ends and profits distributed as UnaxiGold tokens. Public and private dashboards provide transparent insights into transactions, profits, and funds. All platform interfaces, including the website, panels, and dashboards, are exclusively in English. This document outlines the technical specifications of the token, exchange architecture, software components, and security measures.

2. Technical Architecture

2.1. Smart Contract

• Programming Language: Solidity (version ≥0.8.0).

• Standard: ERC-20 with OpenZeppelin extensions (AccessControl, Pausable, ERC20Burnable).

• Networks:

  • Primary: Polygon Mainnet (tested on Polygon Mumbai).

  • Future Phases: BSC, TRX, and other popular networks.

• Features:

  • Dynamic Minting: Tokens minted during purchases by the CEX (MINTER_ROLE), calculated based on input cryptocurrency value (USD equivalent via Oxapay/NOWPayments).

  • Burning: Tokens burned during redemption by BURNER_ROLE or users (with unlocked balance check), reducing circulating supply.

  • Token Locking (Vesting): Pre-sale tokens locked for 3 months (~5,184,000 blocks on Polygon, assuming 2 seconds/block). Locking via dedicated single/batch functions, released post-period.

  • Pre-Sale Profit: 5% monthly profit (15% total for 3 months) minted as tokens at period end by SALE_MANAGER_ROLE.

  • Fee: 2% fee for buy/redemption applied off-chain in the CEX.

  • Access Control: Roles include MINTER_ROLE (minting), BURNER_ROLE (burning), SALE_MANAGER_ROLE (pre-sale management), and DEFAULT_ADMIN_ROLE (overall control and pausing).

  • Pause Functionality: Pause/resume transactions for security (DEFAULT_ADMIN_ROLE).

• Supply Management:

  • Circulating supply tracked via a dedicated variable.

  • No fixed initial supply (dynamic minting based on demand).

• Pre-Sale Profit:

  • Calculation: Locked tokens × 15% (5% × 3 months).

  • Example: 1,000 locked tokens = 1,150 tokens at period end (1,000 + 150 profit).

  • Profits minted by CEX and credited to user wallets.

• Security:

  • OpenZeppelin libraries to mitigate vulnerabilities (e.g., reentrancy).

  • Initial testing with Mythril/Slither.

• Deployment:

  • Test: Polygon Mumbai (gas ≈ 0.01 USD/tx).

  • Live: Polygon Mainnet (gas ≈ 0.05-0.1 USD).

  • Future: BSC (gas ≈ 0.01-0.05 USD), TRX, and others.

• Tools:

  • Hardhat/Truffle for development, testing, and deployment.

  • OpenZeppelin for secure contracts.

2.2. Centralized Exchange (CEX)

    • NOWPayments (https://nowpayments.io/): Supports similar cryptocurrencies.

  • Redemption: Supports stablecoins (USDT, USDC, DAI) with USD-equivalent calculations.
