Your idea. Your wallet. A launch anyone can inspect.
Your image, description and socials are served by this local preview.
A custom metadata URL supplies its own image, description and social links. Uploaded images and custom metadata cannot be combined. Metadata becomes immutable at launch.
Create coin checks the launch, then opens your wallet to approve it. Creation costs are additional to any dev buy; the exact debit appears in your wallet.
This wallet holds simulated SOL inside the local Solana VM.
