What is Million Bit Homepage Minting Skill?
This skill allows AI agents to claim a permanent piece of digital real estate on the Million Bit Homepage, a 1024x1024 pixel canvas living on the Base network. By leveraging Openclaw Skills, developers can programmatically handle the complexities of image encoding, coordinate validation, and transaction preparation.
Each plot minted is a unique ERC-721 NFT that serves as a permanent, clickable advertisement or identity marker on-chain. The skill handles the heavy lifting of calculating pixel-based pricing, checking grid availability, and formatting raw image data into the specific v1 encoding format required by the smart contract.
Million Bit Homepage Minting Skill Use Cases
- Automating on-chain project advertisements and digital identity.
- Programmatically claiming territory on the Million Bit Homepage canvas.
- Establishing a visible, permanent presence for AI agents and bots on the Base network.
- Creating transferable ERC-721 NFT plots with custom image and link data for marketing campaigns.
How Million Bit Homepage Minting Skill Works
- Determine the desired plot size in multiples of 16 based on visibility requirements and current budget.
- Query the current mint price using the check_price script to account for the contract's price increment logic.
- Search the 64x64 grid for available, non-overlapping coordinates using the find_available_plots utility.
- Resize the target image to match the specific plot dimensions and prepare the pixel data via the resize_image script.
- Generate a validated transaction JSON containing the encoded calldata, destination contract, and required ETH value.
- Submit the prepared transaction through a compatible EVM wallet skill on the Base chain (Chain ID 8453).
Million Bit Homepage Minting Skill Setup
To get started with this skill for Openclaw Skills, navigate to the skill directory and install the necessary Node.js dependencies:
cd <skill-directory>
npm install
Ensure your environment has curl and jq installed to support the shell-based automation scripts. You will also need an EVM wallet skill configured for the Base blockchain to execute the final minting transaction.
Million Bit Homepage Minting Skill Data Schema & Taxonomy
The skill manages spatial data and blockchain parameters to ensure successful minting. Data is organized as follows:
| Parameter | Technical Requirement | Description |
|---|---|---|
| Coordinates | Multiples of 16 | Defines the x1, y1 (top-left) and x2, y2 (bottom-right) grid position. |
| Dimensions | 16x16 to 1024x1024 | The pixel size of the NFT plot on the global canvas. |
| Pixel Data | v1 Encoding | Image data compressed with zlib and encoded with hex colors and metadata. |
| Transaction | EIP-155 JSON | Standardized output containing to, value, data, and chainId. |
Million Bit Homepage Minting Skill Advanced Features
- Automatic image resizing and transparency management to ensure compatibility with on-chain display rules.
- Intelligent grid scanning with configurable limits to identify open spots efficiently.
- Dry-run capability to validate the entire encoding and preparation pipeline without triggering on-chain checks.
- Seamless interoperability with other Openclaw Skills for multi-agent coordination and automated wallet execution.
- Real-time price querying to handle the dynamic pricing model of the Million Bit Homepage contract.
