gas-tracker

What This Skill Does

The gas-tracker skill is a robust tool designed for Ethereum ecosystem participants to monitor real-time gas prices, estimate transaction costs, and analyze historical fee trends. By leveraging multiple data sources—including direct RPC calls, the Etherscan Gas Oracle, and Blocknative—this skill provides high-precision data to help users optimize their on-chain interactions. Whether you are performing a simple ETH transfer or deploying a complex smart contract, understanding the current state of the network is critical to avoiding overpayment or stuck transactions.

Installation

To install this skill, use the following command in your OpenClaw terminal:

clawhub install openclaw/skills/skills/sakaen736jih/gas-tracker

Use Cases

• Cost Estimation: Calculate the exact USD and ETH cost of pending transactions based on current network congestion.
• Transaction Optimization: Determine the ideal base fee and priority fee (EIP-1559) to ensure your transactions confirm during periods of high volatility.
• Market Analysis: Track gas price trends over time to identify off-peak hours for minting NFTs or interacting with decentralized finance protocols.
• Automation: Integrate gas monitoring into larger automated workflows to only execute high-cost transactions when the network is sufficiently quiet.

Example Prompts

1. "Check the current Ethereum gas price and tell me how much it will cost to execute a Uniswap swap right now."
2. "What is the recommended priority fee for a fast transaction given the recent EIP-1559 fee history?"
3. "Monitor gas prices for the next hour and alert me when the cost to mint an NFT drops below 20 Gwei."

Tips & Limitations

• Accuracy: While RPC nodes provide the most direct data, always cross-reference with multiple sources like Etherscan and Blocknative for the best estimations.
• Volatility: Gas prices can spike in seconds due to NFT drops or flash liquidations; adjust your priority fees accordingly if your transaction must be included in the next block.
• Permissions: This skill requires network access to query external blockchain endpoints. Ensure your firewall or environment allows outbound connections to Ethereum RPC providers. Be aware that gas estimations are just that—estimates; network conditions change rapidly.
