BSC Memecoin Launchpad

Pump.fun-style launchpad for Binance Smart Chain: token factory + bonding curve sale + auto-liquidity migration to PancakeSwap. Includes Solidity contracts, a Hardhat toolchain, a TypeScript backend, and a minimal Next.js frontend.

Quickstart

Prerequisites

• Node.js 18+
• pnpm/npm/yarn

Install and Build

pnpm install # or npm install / yarn
pnpm build   # compiles contracts

Test

pnpm test

Deploy (example)

Configure network in hardhat.config.ts and set env vars before running:

pnpm hardhat run scripts/deploy.ts --network bscTestnet

Contracts Overview

• TokenFactory: deploys ERC20 token and optionally allocates inventory to the bonding curve
• BondingCurve: sells tokens for BNB on a simple linear curve with fee to treasury
• LiquidityMigrator: placeholder hook to create LP on PancakeSwap and burn LP tokens

Security notes:

• Use audited OpenZeppelin libraries
• Apply caps, cooldowns, and per-wallet limits if needed
• Thoroughly test migration logic on testnet

---

Roadmap

• Implement PancakeSwap router integration and LP burn logic
• Add creator fee/supply options and allowlists
• Indexer and events for sale analytics
• Frontend wallet connect and full flows
