Overview

Four.Meme is a comprehensive smart contract suite for decentralized token creation, fair launches, and liquidity management. Built with security and transparency as core principles, this repository provides production-ready contracts for launching community-driven tokens without pre-sales or venture capital involvement.

The protocol enables developers and communities to:

• Deploy tokens with configurable parameters through an automated factory
• Conduct fair launches with transparent distribution mechanisms
• Establish decentralized liquidity pools for token trading
• Implement vesting schedules for long-term token holder incentives
• Manage token sales with built-in safety features

Features

Core Capabilities

• Fair Launch Protocol: Community-driven token launches without preferential allocation. No pre-sales, no venture capital rounds—just transparent, equitable distribution.

• Decentralized Liquidity Pools: Automated market maker (AMM) integration enabling seamless token swaps and liquidity provision with minimal slippage.

• Token Factory: Streamlined token deployment system with standardized interfaces and configurable tokenomics parameters.

• Vesting Mechanisms: Time-locked token distribution contracts supporting multiple vesting schedules for team allocations, advisor compensation, and community rewards.

• Sale Management: Robust sale handling contracts with configurable caps, whitelisting, and automated distribution.

Technical Specifications

• Solidity Version: ^0.8.0
• Security Framework: OpenZeppelin-based implementations
• Testing Coverage: Comprehensive unit and integration tests
• Gas Optimization: Efficient contract design minimizing transaction costs
• Upgradeability: Modular architecture supporting future enhancements

Component Interactions

1. Token Creation: TokenFactory deploys ERC-20 compliant tokens with custom parameters
2. Fair Launch: FairLaunch contract manages initial distribution and price discovery
3. Liquidity Management: LiquidityPool provides automated trading infrastructure
4. Token Vesting: TestVesting handles time-locked token releases
5. Sale Coordination: SaleHandler orchestrates token sales with configurable parameters

Installation

Prerequisites

• Node.js >= 16.0.0
• Yarn or npm package manager
• Foundry or Hardhat development environment
• Solidity compiler ^0.8.0

Setup

# Clone the repository
git clone https://github.com/frogansol/four.meme-forking-smart-contract
cd four.meme-forking-smart-contract

# Install dependencies
yarn install

# Compile contracts
yarn compile

# Run test suite
yarn test

Usage

Deploying a Token

// Example: Deploy a new token using TokenFactory
ITokenFactory factory = ITokenFactory(FACTORY_ADDRESS);
address newToken = factory.createToken(
    "MyToken",
    "MTK",
    1000000 * 10**18,
    msg.sender
);

Launching a Fair Launch

// Configure and start a fair launch
IFairLaunch fairLaunch = IFairLaunch(FAIRLAUNCH_ADDRESS);
fairLaunch.initializeLaunch(
    tokenAddress,
    startTime,
    endTime,
    softCap,
    hardCap
);

Deployment Scripts

Pre-configured deployment scripts are available in the script/ directory:

# Deploy all core contracts

# Run specific test file
yarn test test/fourtoken.test.sol

# Generate coverage report
yarn coverage

Security

Security is paramount in the Four.Meme ecosystem. Our contracts follow industry best practices:

• OpenZeppelin library integration for battle-tested implementations
• Comprehensive unit and integration testing
• Access control mechanisms on privileged functions
• Reentrancy guards on state-changing operations
• Input validation and bounds checking

Security Audit Status: Pending external audit. Use at your own risk in production environments.
