Build & Launch SPL Tokens Instantly on Solana – My Dev Journey with Token-2022

Hey Devs 👋

I just built a small tool called Solana Token Launchpad — a lightweight frontend + backend app to help you create your own SPL Token using the new Token-2022 extensions.

You can:

Enter token name, symbol, image URL, and supply
Upload metadata
Deploy your token mint with on-chain metadata
Mint tokens directly to your wallet

🛠 Tech Stack:

React + TailwindCSS
Solana Wallet Adapter
Express.js + MongoDB for dynamic metadata URI

💡 The tricky part:

I struggled a bit with dynamic metadata URIs — since Solana expects a metadata URL, and each token needs a unique one.

To solve it, I:

Created a simple MongoDB backend to store name/symbol/image

Used the generated Mongo _id to construct dynamic metadata URLs like:

https://myapi.com/metadata/<tokenID>

This endpoint returns the full metadata JSON Solana needs to initialize the token.

🎬 Demo:

Input your token details and launch instantly on devnet.

If you're building on Solana, would love feedback, suggestions, or ideas to improve this 🙌
Feel free to fork or remix it for your own dapps.

Thanks for reading & happy hacking! 🧙‍♂️
