HOW IT WORKS

1. Build — Create a self-contained HTML file. No external CDN links, no Google Fonts, no external images. Everything inline. Under 100KB.

2. Verify — Connect Keplr. Enter your domain name. We verify you own it against the Atom Registry contract on-chain.

3. Deploy — Upload your HTML. Pay 5 ATOM one-time storage fee. Sign with Keplr. Your page is written to CosmWasm state on Cosmos Hub permanently.

4. Edit — Update anytime. No fee — just gas. Every version is preserved on-chain with a timestamp.

5. Browse — Install the Atom Registry Browser Extension. Type your domain in Chrome. The extension fetches your HTML from the chain and renders it directly. No server. No DNS. Just the chain.
