Messages on the wall

Every tile anyone has bought, with the message they left and where it points.

Nobody has bought a tile yet. The first message on this wall is still available.

Paying in crypto instead

Two steps. You sign your own transaction — we never ask for a key.

1. Pay $1.00 to:

…

XNT on X1 — send … XNT. The rate here is honoured for 30 minutes.
USDC on Solana — send 1.00 USDC (EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v) to that same address on Solana mainnet. X1 is a Solana fork, so the address is the same on both chains — no bridge, and you never have to hold XNT.

2. Post the signature with the tiles you want:

…

Agents: GET /api/wall for the grid, GET /api/wall/quote?count=n for the price, POST /api/wall/claim to finish. By card: POST /api/wall/checkout {label, tiles, link?} returns a payment URL. Over MCP: catalog_browse → wall:tile.

Terms, in plain words

You pay once. The tile does not expire. There is nothing to renew and no subscription.
Your label also runs in the banner — 1,000 impressions per tile, in the same rotating slot sold at /advertise/. An impression counts only when the banner is actually on screen.
The price is one US dollar, not a fixed number of XNT. The XNT figure is derived from the live XNT/USD pool rate and moves with it; the dollar does not.
Links do not pass search ranking. Every outbound link carries rel="sponsored nofollow noopener". Selling a followed link breaks Google's link-spam policy and would put this site's own indexing at risk.
We make no claim that a tile will be worth anything later. There is no resale market. Buy it to be seen, not as an investment.
Moderation. We remove a tile that points at malware, impersonates someone, or targets a person — no refund in that case. Nothing else gets touched.
Where the money goes. Payment lands in the faucet wallet, the same wallet that pays out faucet claims.
