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 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: SizePixelsVisibilityRelative Cost16x16256Tiny icon1x (cheapest)32x321,024Small logo~4x64x644,096Clearly visible~16x128x12816,384Prominent~64x Always run check_price.sh to get the exact current price before minting. ### 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 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 --limit 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 Returns {"available": true, ...} or {"available": false, ...}. ### 5. Prepare your image If your image doesn't match the plot dimensions, resize it: scripts/resize_image.sh [output_path] The script force-resizes to exact dimensions and replaces transparency with white. ### 6. Prepare the mint transaction This is the main script. It validates everything, checks availability, queries the price, encodes the pixel data, and outputs a ready-to-submit transaction: scripts/prepare_mint.sh Example: scripts/prepare_mint.sh my_logo.png 992 128 1024 160 https://myproject.com Returns transaction JSON: { "to": "0x25b9afe64bb3593ec7e9dc7ef386a9b04c53f96e", "value": "0x2dc8b1d1680000", "data": "0xdd2e6e7d...", "chainId": 8453, "description": "Mint 32x32 plot at (992,128) on Million Bit Homepage linking to https://myproject.com", "meta": { "price_eth": "0.012887040000000000", "price_wei": "12887040000000000", "size": "32x32", "url": "https://myproject.com" } } Use --dry-run to skip on-chain checks and just test the encoding pipeline. ### 7. Submit the transaction Pass the output JSON to your EVM wallet skill to execute the transaction on Base chain (chainId 8453). The key fields are: to -- the contract address value -- ETH to send (the mint price, in hex wei) data -- the ABI-encoded calldata chainId -- 8453 (Base) ### Script Reference All scripts live in scripts/ (relative to this file) and output JSON to stdout. Status messages go to stderr. ScriptPurposeInputscripts/check_price.shGet current mint price or scripts/check_availability.shCheck if coordinates are free scripts/find_available_plots.shScan grid for open spots [--limit N]scripts/resize_image.shResize image to plot size [output]scripts/prepare_mint.shFull pipeline: outputs tx JSON [--dry-run] ### Common Issues "Coordinates overlap" -- that spot is taken. Use find_available_plots.sh to find open spots. "must be a multiple of 16" -- all coordinates and dimensions must be divisible by 16. Image wrong size -- prepare_mint.sh auto-resizes if the image doesn't match the plot dimensions. Price changed -- price increases with each new mint. Re-run check_price.sh for current pricing. Transaction reverts -- ensure your wallet has enough ETH on Base to cover the price plus gas. ### Technical Details Contract: 0x25b9afe64bb3593ec7e9dc7ef386a9b04c53f96e on Base (chain ID 8453) Standard: ERC-721 (Million Bit Homepage / MBH) Pixel data: Images are encoded in v1 format (16x16 segments with hex colors + URL), compressed with pako/zlib, and stored on-chain in the mint transaction calldata ## Trust - Source: tencent - Verification: Indexed source record - Publisher: millionbithomepage - Version: 1.0.0 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-04-30T04:46:21.606Z - Expires at: 2026-05-07T04:46:21.606Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/millionbit-mint) - [Send to Agent page](https://openagent3.xyz/skills/millionbit-mint/agent) - [JSON manifest](https://openagent3.xyz/skills/millionbit-mint/agent.json) - [Markdown brief](https://openagent3.xyz/skills/millionbit-mint/agent.md) - [Download page](https://openagent3.xyz/downloads/millionbit-mint)
