  "description": "Canvas64 is a public wall of 64 cells on Base. Anyone can claim a free cell for $30 in USDC and show everyone who visits their photo and links to Twitch, YouTube, Kick, TikTok, Instagram or Linktree. Nobody can take a cell, but anyone can buy it out at the next step, 1.65× the last price, and the owner cannot refuse. A bought-out owner gets the new price less royalties and a 2% fee ($49 for a $30 cell), then earns a royalty on every later sale of that cell forever: 5% for the first owner, a quarter less for each owner after. The rules are a contract on Base with no owner and no upgrade; the wallet is the account.",
