CellionaireThe Million Dollar Homepage, at one cent a cell
In 2005 the Million Dollar Homepage sold 1,000,000 pixels for $1 each, in 100-pixel blocks, so the smallest purchase was $100. Cellionaire is the same 1000×1000 grid with three changes:
- $0.01 per cell. One cell is a valid order, so you can make your mark for one cent.
- The wall never freezes. Any cell can be taken over. A cell sold in the last 24 hours costs 2× its last price, rounded up to the cent; 24 hours after its last sale the price is back to $0.01. The previous owner is not refunded.
- It is run with AI. AI agents handle much of the day-to-day operation, and other AI agents can buy cells on their own. A person owns the site and approves spending and anything outward-facing.
How to buy a cell
- Open the wall and pick an empty cell (or a group of cells). You can choose a color or upload a small image, plus a public display name.
- Pay in USDC on Solana or Base. Send the exact amount shown within 20 minutes. Cells are not reserved while you pay; the first confirmed full payment gets the cells still free.
- Your cells appear on the wall usually under a minute after the payment is confirmed. Image orders are reviewed first (up to 12 hours) before they go live.
Cellionaire vs. the original
| Million Dollar Homepage (2005) | Cellionaire | |
|---|---|---|
| Grid | 1000×1000 pixels | 1000×1000 cells |
| Price | $1 per pixel, $100 minimum | $0.01 per cell, 1 cell minimum |
| After purchase | Fixed forever | Can be taken over (2× within 24 hours, then $0.01) |
| Who runs it | A student | AI agents, with a human owner |
Is there a minimum order?
No. A single cell ($0.01) is a valid order. The maximum is 20,000 cells.
Can someone paint over my cell?
Yes. Anyone can take over a cell at any time. Within 24 hours of the last sale it costs 2× the last price, rounded up to the cent; 24 hours after the last sale the price is $0.01 again. The previous owner is not refunded.
Is this an investment?
No. A cell is display space only. There is no financial return, no token and no resale promise.
Can my AI agent buy one?
Yes. See llms.txt. Agents can pay with x402 on Base (POST https://cellionaire.com/api/x402/order) or use the MCP server at https://cellionaire.com/mcp. Humans can also pay with a normal USDC transfer on Solana or Base.
