An MVP launchpad for AI model tokens built on Base, integrating the Aerodrome liquidity protocol to enable one-click token deployment and initial liquidity seeding.

🌐 Live Demo: aerodrome-ai-launchpad.vercel.app

🎬 Demo Video:

Aerodrome AI Launchpad is a minimal viable product for launching AI model tokens. Users simply fill in a few parameters to complete the full on-chain launch flow on Base Sepolia:

1. Deploy a standard ERC20 token contract
2. Approve the router to spend tokens
3. Create a liquidity pool on Aerodrome and seed initial liquidity
4. Display launch results (token address, pool address, LP token balance, etc.)

• Framework: Next.js 16 + TypeScript
• Styling: Tailwind CSS
• Chain Interaction: viem + wagmi
• Wallet Connection: RainbowKit
• Target Chain: Base Sepolia (testnet)
• DEX Protocol: Aerodrome Finance (Velodrome architecture)

• Fill in token name, symbol, initial supply, initial ETH amount, and description
• One-click ERC20 deployment after form validation
• Automatically detects and creates an Aerodrome pool if one doesn't exist
• Automatically approves and calls addLiquidityETH to seed liquidity
• Real-time step status display (deploying / approving / adding liquidity)
• Shows final results: token address, tx hash, pool address, LP token balance

• Three modes: Buy (ETH → Token), Sell (Token → ETH), Swap (Token → Token)
• Real-time quotes via router getAmountsOut
• Price impact calculation based on AMM reserves
• Slippage tolerance and minimum received amount protection
• Friendly balance-check messages instead of raw contract errors

• Node.js >= 18
• pnpm or npm

pnpm install

Create a .env.local file:

NEXT_PUBLIC_WALLETCONNECT_PROJECT_ID=your_walletconnect_project_id

pnpm dev

Open http://localhost:3000

Deployment config is in deployments/baseSepolia.json:

Validate Form → Deploy ERC20 → Check/Create Pool → Approve Router → addLiquidityETH → Read LP Balance

The pool address is extracted from logs[0].data of the createPool transaction receipt (first 32 bytes decode to the pool address).

Enter Amount → getAmountsOut Quote → Check Balance → Approve → Swap

• Buy mode: calls swapExactETHForTokens
• Sell mode: calls swapExactTokensForETH
• Swap mode: calls swapExactTokensForTokens (two-hop route via WETH)

• This project runs on Base Sepolia testnet only — make sure your wallet is on the correct network
• Adding liquidity requires testnet ETH, available from the Base Sepolia Faucet
• LP token balance has a ~2 second delay after the transaction confirms while waiting for chain state to sync
