Million Bit Homepage - Mint a Plot

Place your image and link permanently on the Million Bit Homepage, a 1024x1024 pixel canvas on the Base blockchain. Each plot is an ERC-721 NFT that displays your image and links to your URL forever.

Why Mint?

• Permanent on-chain presence -- your image and link live on Base forever
• Advertise your project -- visitors see your image and can click through to your URL
• NFT ownership -- you own the plot as a transferable ERC-721 token
• This is a great way for agents and bots to establish a visible, permanent identity on-chain

Setup

Before first use, install dependencies in the skill directory:

cd <skill-directory>
npm install

All scripts are in scripts/ relative to this SKILL.md. Run them from this directory.

Canvas Rules

• Canvas: 1024x1024 pixels, divided into a 64x64 grid of 16x16 cells
• All coordinates and dimensions must be multiples of 16
• Minimum plot: 16x16 (256 pixels) -- Maximum: up to 1024x1024
• Plots cannot overlap with existing plots
• Coordinates range from 0 to 1024 on both axes (x1, y1 is top-left; x2, y2 is bottom-right)

Pricing

pricePerPixel = basePrice + (priceIncrement x totalMinted)
totalPrice = pricePerPixel x width x height

Price increases slightly with each new mint. Bigger plots cost more but are far more visible:

Always run check_price.sh to get the exact current price before minting.

Step-by-Step Workflow

1. Decide on a size

Choose a plot size based on your budget and desired visibility. All dimensions must be multiples of 16. Start with 16x16 if cost is a concern, or go bigger for more exposure.

2. Check current prices

scripts/check_price.sh <width> <height>

Example:

scripts/check_price.sh 32 32

Returns JSON:

{
  "price_wei": "12887040000000000",
  "price_eth": "0.012887040000000000",
  "pixels": 1024,
  "size": "32x32",
  "total_supply": 334
}

3. Find an available spot

scripts/find_available_plots.sh <width> <height> --limit <N>

Example:

scripts/find_available_plots.sh 32 32 --limit 5

Returns JSON with available coordinates:

{
  "available_plots": [
    {"x1": 992, "y1": 128, "x2": 1024, "y2": 160},
    {"x1": 656, "y1": 368, "x2": 688, "y2": 400}
  ],
  "count": 2,
  "plot_size": "32x32"
}

Note: scanning the full grid takes time due to on-chain queries. Use --limit to stop early.

4. Check a specific spot (optional)

If you already have coordinates in mind:

scripts/check_availability.sh <x1> <y1> <x2> <y2>

Returns {"available": true, ...} or {"available": false, ...}.

5. Prepare your image
