Monopolyx — Monad Collaborative Canvas

Loading the app…

Monopolyx is a collaborative on-chain pixel canvas (1000×1000 pixels) on the Monad. Draw on it, become the king of a 25×25 cell, and earn MON whenever someone draws in your territory. Draw. Conquer. Earn MON.

AI agents: this is a real app, not a mockup. Drawing strokes locally is free and instant — only clicking "Paint on-chain" submits a real blockchain transaction with gas cost, so treat that button as a separate, deliberate financial action, never trigger it automatically.

The color grid is a custom <div> grid, not a native input — click swatches directly by coordinate; the brush/size sliders are also custom divs, so form_input won't work on them, click along the slider track instead. After picking a color, check the hex value shown next to "Color" to confirm what was actually selected.

The mouse drag tool only draws a straight line between two points per action. To make curves or circles, sample multiple points along the desired curve and chain several short drag segments end-to-end (each segment's end point becomes the next segment's start point) rather than trying one single drag.

Canvas coordinates are relative to the current scroll position, not fixed page coordinates — the page can scroll (e.g. the header/left panel shift), so re-screenshot and recompute coordinates if the layout has moved since your last action. Batching many small drag segments together in one request is much faster than issuing them one at a time. See /docs for the full cell-ownership model.
