💊 NadFun Monad Smart Contract

The Nad.fun Monad Smart Contract brings the power of viral, one-click token creation to the EVM-Compatible blockchain, mirroring the simplicity and virality of the original Nad.fun on Solana. This version is built natively for Monad's EVM-compatible testnet, with full support for Uniswap liquidity migration, enabling instant tradability in the broader Ethereum ecosystem.

✨ Key Features

• Token Creation: Instantly create customizable tokens (name, symbol, total supply) on Monad.

• Bonding Curve Pricing: Implements a linear bonding curve for fair price discovery, rewarding early buyers.

• Auto Liquidity Management: Seamlessly manage buys/sells using an embedded bonding curve—no AMM setup required.

• Uniswap Migration: Once the liquidity threshold is hit, migrate liquidity to Uniswap V2/V3 for open DeFi trading.

• Full Onchain Execution: All logic is executed onchain—including minting, pricing, and migration—for maximum transparency and decentralization.

• EVM-Compatible: Written in Solidity, deployed on Monad, and fully interoperable with Ethereum tooling like Hardhat, Foundry, and MetaMask.

• 🚀 Uniswap Liquidity Migration 🚀: After sufficient buy-in volume is reached, token liquidity is automatically migrated to a Uniswap pool—allowing users to continue trading in the open market with real-time pricing and increased exposure.

• 🚀 Token Authority Options 🚀: Smart contract logic supports optional authority revocation or time-bound admin permissions, ensuring flexibility in launch strategy (community-led or project-driven).

🔄 Contract Flow Overview

1. Token Launch

   • A creator calls launchToken with the desired name and symbol.
   • The factory deploys a dedicated NadToken, mints an initial supply to the creator, and seeds the bonding curve with predefined virtual reserves.
   • Any ETH sent alongside the launch call executes the first buy: the factory takes the protocol fee, updates the bonding-curve reserves, and mints the appropriate token amount back to the creator.

2. Secondary Buys (External Integrations)

   • Frontends or scripts can continue calling launchToken with additional ETH (same token address) to simulate buys until liquidity migration occurs.
   • Each buy applies the bonding-curve formula _calculateReserveAfterBuy, deducts the fee, and sends newly minted tokens to the buyer.

3. Selling Back to the Curve

   • Holders call sellToken(tokenAddress, amount) before liquidity migration.
   • The factory computes the ETH out based on the updated reserves, with a fee routed to accumulatedFees.
   • Tokens are pulled via transferFrom, reserves are updated, and the seller receives ETH directly from the contract balance.

4. Admin Controls

   • updateReserves, updateFeeRate, and updateLiquidityMigrationFee let the owner tweak global defaults for future launches.
   • claimFee withdraws all accumulated protocol fees to a specified address.

5. Liquidity Migration (Future Expansion)

   • Parameters such as liquidityMigrationFee, the stored Uniswap router address, and the WETH handle are prepared for the migration feature.
   • A future release can integrate the LiquiditySwapped event to track the actual migration into Uniswap V2 once thresholds are met.
