# $MWXT Smart Contract

🔆 Overview

**MWXT** is a secure, transparent, and upgradeable digital asset built to facilitate payments, governance, and deflationary incentives across our AI marketplace.

***

### 🎯 Purpose & Scope

**Purpose:**\
Define and implement a best-in-class ERC-20 token that is gas-efficient, upgradeable, and governed securely.

**Scope:**\
Covers the token’s on-chain behavior, administrative controls, and integration points with our wider platform.

***

### 🥅 Goals

* **Security:** Leverage battle-tested libraries, rigorous audits, and time-locked controls.
* **Efficiency:** Optimize gas for transfers, approvals, and permit operations.
* **Flexibility:** Support on-chain upgrades and off-chain permit signatures.
* **Deflationary Design:** Shrink supply via transaction burns, quarterly buy-back, and holder burns.

***

### ⚙️ Core Features

#### 1. ERC-20 Compliance

* Standard methods: `totalSupply()`, `balanceOf()`, `transfer()`, `approve()`, `transferFrom()`, `allowance()`
* 18 decimals, symbol **MWXT**, name **MWX Token**

#### 2. Upgradability

* **UUPS proxy** (via OpenZeppelin ERC1967Proxy)
* Admin role protected by a **48-72h Timelock**

#### 3. Permit Functionality (EIP-2612)

* Off-chain approvals through `permit()`
* Standardized EIP-712 domain separator

#### 4. Access Control

* **Ownable** for critical actions (pause, burn, upgrade)
* Smooth ownership transfer

#### 5. Timelock Mechanism

* All admin actions queue for review
* Ability to cancel or execute after delay

#### 6. Minting & Burning

* **One-time mint** at deployment (fixed 1 billion supply)
* `burn(amount)` lets holders destroy tokens

#### 7. Emergency Pause

* **Pausable** to halt transfers if needed
* Unpause also governed by Timelock

### 🔥 Deflationary Mechanics

1. **Transaction Burn:** 20 % of each marketplace commission is burned immediately.
2. **Quarterly Buy-Back:** 15 % of net profits are converted to MWXT and burned.
3. **Holder Burns:** Any holder can call `burn()` to reduce supply further.

***

### 🛡️ Security & Testing

* **Audits:** Independent third-party reviews (OpenZeppelin, Trail of Bits)
* **Bug Bounty:** Immunefi program with private→public phases
* **Test Suite:** Unit, integration, and fork testing; ≥ 90 % coverage
* **Static Analysis:** Slither, MythX scans
