Hi HN, I built this side project earlier this week. It executes an English auction on Solana with a reserve price of 0.1 SOL. Auction losers get refunded (minus a <$0.01 processing fee). The Codex agent operates in a sandbox and can only output HTML/JS/CSS.

The project is open-source: https://github.com/neelsomani/the-daily-auction

Assuming the codex editor is the editor for the area below the auction counter, isn't that a security vulnerability that can put the site audience at risk?

The Codex agent is only given tools to edit the single HTML file that displays on the homepage. The page is on a separate domain, so there's no cookie sharing, and the iFrame is in a sandbox. That said, the biggest risk is social engineering attacks.

What’s to stop someone rewriting the iframe wrapper to hide the real iframe and display a fake one?

They cannot edit the iFrame itself. The user is allowed to edit the contents within the iFrame.

Fuck, another brilliant idea that was easy to make, but I didn't do.

It reminds me of the million dollar website where each pixel was sold as advertisement.

Since then a million other "million _____" websites popped up. I saw a site selling one million text lines for $1 apiece. Last I saw they sold one line, now the site is gone [edit: INCORRECT].

Found the site: https://www.themillionlines.com/

They sold around 632 for what its worth no?

Why would anyone go to that site however? I mean novelty, once...but didn't advertising figure out ages ago that number of eyes on something matters?

That's the one. :)

I also think that's one of those lucky/momentum deals, wasn't it each pixel was $1 or were they worth more? There are a million companies out there (to ask)?.

From what I remember, some people bought sections so their company icon was visible on the page.

They only sold in 10x10 increments (for $100).

there are thousands of this over the internet.

Show more of the cool ones, would ya?

they are all very bland, more eg: https://www.florin-pop.com/one-million/

Ideas don’t have to be unique. You can create your own version

I am sure that there will be detractors, who will tell you that it has been done before ( and in a sense, it is true; nihil novi and all that ). That said, this is done in a way that moves a little closer to that fascinating reality present in 'transmetropolitan' graphic novels, where things online are in near constant flux. Kudos.

Appreciate that. I didn't realize how derivative this was when I built it! I was just trying to build something cool with the Codex SDK.

So cool! And the timing is funny, we just launched a very similar (albeit much simpler) experiment, sans crypto (https://www.the-last-word.com/).

Micro-marketplace experiments must be in the zeitgeist, excited to see what else emerges.
