The contract stores every pixel and its painter. The board updates for everyone.
Simple rules, fair fights.
Nobody owns a pixel for good. The canvas belongs to whoever shows up.
0.00001 ETH a pixel, about three US cents. The price can only move between 0.000001 and 0.001 ETH.
Painting a pixel someone painted in the last 10 minutes costs twice as much, so wars cool down.
There is no erase or reset function. The owner can only adjust the price within the bounds and move fees to the treasury.

Questions.
What do I need?
A wallet on Robinhood Chain with a little ETH. 100 pixels cost 0.001 ETH plus gas, which is a fraction of a cent.
Can someone paint over my art?
Yes, that's the game. Recently painted pixels cost double to overwrite, which gives defenders an edge.
Where is the canvas stored?
In the contract itself: 5 bits per pixel, packed into 322 storage slots. Anyone can read it with one call.
Where do the fees go?
To the Plazza treasury. The contract never holds anything else, and there is nothing to withdraw for players.
