Hello world
fee.pump.fun is a subdomain of pump.fun (the popular Solana memecoin launchpad). As of now, the site is a very basic page that simply displays “Hello World!” — it looks like an early placeholder, landing page, or newly launched tool
A recent mention on X (August 21, 2026) linked it alongside a Solana wallet address, suggesting it may be tied to a specific project, fee-claiming tool, or announcement related to pump.fun’s creator fees
