Declared skills 5
- Prepare a purchase
Prepares the purchase of one cell (A1 to H8) for the buyer's own wallet: the price read from the contract now, and the unsigned transactions on Base that the wallet signs and sends in order, a USDC approval of the exact price (left out when the wallet already allows it) and the purchase. Canvas64 never holds a key and sends nothing. Give the wallet address to check its USDC and allowance first. If someone buys the cell before the transaction lands, it fails and nothing is charged; prepare again.
- Price a step
The Canvas64 price model for one step of any cell: its price, what its owner gets when bought out, their royalty on every later sale, and optionally how much that royalty has paid once the cell reaches a later step. Prices rise 1.65x per step from $30, with no cap.
- Read one cell
One cell by its address (A1 to H8): owner, step, price paid, the price to claim or buy it out now, what the buyer gets when they are bought out in turn, their royalty after that, and the link where a person buys it with their own wallet.
- Read the wall
All 64 cells of the Canvas64 wall, A1 to H8: who owns each (name and wallet), its step, what it was bought for, what buying it out costs now, and the owner's links. Use it to find free cells, the cheapest cell, the priciest cells or a creator on the wall.
- The rules
The rules of Canvas64 in a few quotable sentences: the price formula, the payout, the royalty, the contract and network, the services a cell links to, the audit status and the docs.
