The rules of the wall
Canvas64 is a wall of 64 cells. A cell shows its owner’s photo and links to everyone who comes to the wall. These rules are written into a contract on Base: no owner, no upgrade, no key that can move anyone’s money.
A cell
- A free cell costs $30. You pay once, in USDC on Base, from your own wallet. The wallet is your account: there is nothing to sign up for.
- Nobody can take a cell. Anyone can buy it out at the next step, and nobody can refuse a buyout.
- Every buyout raises the price 1.65×, with no cap.
- When your cell is bought out you get the new price less the royalties and the fee: $49 for a cell you claimed for $30.
- After that you earn a royalty on every later sale of that cell, forever, paid in the same transaction as the sale.
Where every buyout goes
- The seller, the cell’s current owner, gets the rest of the price.
- Every earlier owner gets a royalty: the first owner 5%, the second 3.75%, each one a quarter less than the one before. All royalties together never reach 20% of a sale.
- The platform takes a fee of 2%. Every claim’s $30 goes to the platform too.
- A payment that fails, for example to an address that cannot receive USDC, is held by the contract until its owner withdraws it.
The price ladder
The first 20 steps of every cell. The owner’s royalty is what that owner earns of every sale after they are bought out.

What the team can do
- Stop new sales for an emergency, seven days at a time. Each stop lapses by itself unless the team renews it, and every stop is public on the chain; payments owed, withdrawals and profiles keep working throughout.
- Move the platform’s own share to a new address.
- Nothing else: it cannot change a price, a rate or an owner, take a cell, or touch anyone’s money.
Photos and names
- An owner sets a nickname, an avatar or a photo and links to their Twitch, YouTube, Kick, TikTok, Instagram or Linktree by signing a message in their wallet. It costs nothing and is not a transaction.
- Every photo is screened before it shows, and nothing explicit goes up. Three reports from different visitors hide a cell’s photo and name until its owner changes them. The cell itself, and what it earns, stay theirs.
