How it works 如何使用

Try it

Step 1

Pick your blocks

选格子

Drag a rectangle over open blocks. Anything from a single block up to 10 by 10.

Step 2

Pin your ad

钉上广告

A picture, a title and a link. The picture is packed to 24 KB and kept inside the contract itself.

Step 3

Pay for days

按天付费

1 to 90 days at a time, in ETH, from your own wallet. Add more days while your ad runs.

Step 4

Time runs out, the wall moves on

到期即开放

When your days end, your blocks open again. Anyone can take all of them or just a few for the next ad. Nobody can take them while your ad runs.

No media kit. No invoices.

不用媒体资料包，不用发票，一笔交易就上墙。

// pick blocks, pin an ad, pay for days
const cost = await wall.quote(4, 3, 30);

await wall.rent(
  12, 8,        // top left block
  4, 3,         // 4 wide, 3 tall

  image,        // up to 24 KB, stored on chain
  "Your brand here",
  "https://your.site",
  { value: cost }
);

On the wall the moment the block lands. Off the wall the second your days end.

Questions 常见问题

What happens when my days run out?

Your ad comes off the wall and its blocks open again. Anyone can rent all of them or just some of them for a new ad. You can rent them again too, if nobody got there first.

Can someone take my blocks while my ad runs?

No. The contract refuses any rental that touches a block with a running ad on it. Your blocks are yours until your last second.

Where is my picture kept?

Inside Robinhood Chain. The site packs your picture to at most 24 KB and the contract stores the bytes as their own small contract, so the ad shows for as long as the chain runs, with no file host to go down.

Can I change my ad or add days?

Yes. While your ad runs you can swap the picture, the title and the link, and add 1 to 90 days at a time, up to a year ahead. You can also hand the ad to another wallet.

Who can hide an ad?

The wall has a moderator who can hide the picture, title and link of an ad that breaks the rules: nothing illegal, no scams, no adult content, no malware links. A hidden ad keeps its blocks until its days end, and its owner can swap in a new picture.

Are there refunds?

No. Every payment goes straight to the treasury in the same transaction, and the wall itself never holds funds. Pick your days with care: you can always add more later.

Which wallet do I need?

Any browser wallet that can switch to Robinhood Chain (chain 4663), with a little ETH for the rent and gas. The site asks your wallet to add the chain if it does not have it yet.
