Solana Token Launchpad

A minimal React/Vite app that lets you create your own SPL token on Solana Devnet in seconds.

⚠️ Note: This basic launchpad does not include on-chain metadata (name, symbol, logo). If you need metadata support (e.g. upload a JSON image URI to Arweave/IPFS and attach it), you’ll need to integrate a metadata instruction via Metaplex or a backend service.

🚀 Features

• Create a new SPL token with custom initial supply
• Wallet-adapter UI for Phantom, Solflare, Backpack, Glow, Torus
• Pure frontend; no backend required
• Minimal dependencies: @solana/web3.js & @solana/spl-token

---

🛠️ Installation

1. Clone this repo

   git clone https://github.com/your-username/solana-token-launchpad.git
   cd solana-token-launchpad

Install dependencies

bash Copy Edit npm install Start dev server

bash Copy Edit npm run dev Open http://localhost:5173 in your browser

📋 Usage Click Select Wallet in the top-right and connect Phantom (or another adapter).

Fill in Token Name, Symbol (UI only), and Initial Supply.

Click Create a Token.

View the transaction signature in an alert and check Devnet Explorer.

📝 Adding Transaction Fees If you’d like to charge a fee (e.g. 0.01 SOL) before minting, modify the createToken function:

ts Copy Edit import { SystemProgram, LAMPORTS_PER_SOL } from "@solana/web3.js";

// inside createToken(): const feeIx = SystemProgram.transfer({ fromPubkey: wallet.publicKey, toPubkey: new PublicKey("YOUR_FEE_WALLET_ADDRESS"), lamports: 0.01 * LAMPORTS_PER_SOL, });

const tx = new Transaction().add( feeIx, /* ...other mint instructions... */ ); That ensures the user pays your platform wallet before the token is created.

⚙️ Adding Metadata Support To attach name/symbol/logo on-chain, integrate Metaplex’s Token Metadata program:

Install:

bash Copy Edit npm install @metaplex-foundation/mpl-token-metadata Derive the metadata PDA and call createCreateMetadataAccountV3Instruction()

Host a JSON (with name, symbol, image, description) on Arweave/IPFS

Add the metadata instruction into your mint transaction

See Metaplex docs for full details.
