Advertise with USDC on Base

A Canvas64 cell is an ad spot you pay for once in USDC on Base: $30 for a free cell, from your own wallet, with no account, no subscription and no middleman. It shows your photo or logo, your name and links to Twitch, YouTube, Kick, TikTok, Instagram, X or Linktree to everyone who visits the wall, and it stays yours until someone pays more for it. When they do, the money goes to you.

What you get for $30

• A cell on a public wall of 64, shown large enough to read without zooming, with its own page such as https://canvas64.com/D4 to link from anywhere.
• Your photo, name and links, set and changed by you at any time after you sign in with the same wallet. A photo is screened before it shows.
• A place on the boards. The three priciest cells are shown again on large boards above the wall, ranked No. 1 to No. 3.
• No running cost. You pay once. There is no renewal and nothing to cancel.

When someone buys your spot

Anyone can buy a cell out at the next step, 1.65× the last price, and the owner cannot refuse. That is what pays you:

• For a cell you claimed for $30, the next buyer pays $50 and you get $49 in the same transaction.
• After that you keep a royalty of 5% on every later sale of that cell, forever, paid by the contract to your wallet.
• Prices climb $30, $50, $82, $135, $222 and on: the full table is on Prices.

If you want the spot back, you buy it at the next step like anyone else.

Who uses it

• Streamers and creators: a cell links straight to your channel on Twitch, YouTube or Kick.
• Crypto projects and brands on Base: you already hold USDC there, so a claim is two signatures from your wallet.
• AI agents and their builders: an agent can find a free cell and prepare the purchase for your wallet over a public MCP server.

How to claim a cell

1. Get USDC on Base in a wallet such as Coinbase Wallet, MetaMask or Rainbow, plus a little ETH there for the network fee: wallets and paying.
2. Open the wall, pick a free cell and press Claim.
3. Approve exactly $30 of USDC and confirm the purchase. The cell shows your wallet's name at once; add your photo and links when you like.

Read Before you buy first: a purchase is final, and what a cell earns depends on later buyers.
