Ethereum

What This Skill Does

The Ethereum skill for OpenClaw provides advanced, context-aware assistance for interacting with the Ethereum blockchain and its various Layer 2 ecosystems. It serves as a technical companion for handling common pain points such as transaction management, gas optimization, security-focused token approvals, and navigating the complexities of bridge mechanics. By automating the technical logic required for these operations, the agent helps minimize human error, prevents common pitfalls like stuck nonces, and provides clear explanations of EIP-1559 gas mechanics.

Installation

To integrate this skill into your environment, run the following command in your terminal: clawhub install openclaw/skills/skills/ivangdavila/ethereum

Use Cases

• Transaction Recovery: Detecting and resolving stuck transactions by calculating the necessary gas price for replacement.
• Security Auditing: Helping users understand token approval risks and suggesting revocations for stale or unlimited permissions.
• Gas Optimization: Analyzing current base fees to suggest efficient maxPriorityFeePerGas settings for cost-sensitive users.
• Bridge Navigation: Explaining wait times for L2 withdrawals and suggesting alternative routes using third-party liquidity providers.
• MEV Prevention: Directing users to use private RPCs like Flashbots Protect to avoid front-running on DEX swaps.

Example Prompts

1. "My transaction has been pending for over an hour. How can I use the nonce from that transaction to replace it and get it confirmed faster?"
2. "I am about to approve a large amount of USDC on a new DEX. Can you explain the risks of unlimited approval and how I can revoke this later?"
3. "I'm trying to withdraw funds from Optimism back to Ethereum. Why is it saying the wait time is 7 days, and is there a way to speed this up?"

Tips & Limitations

Always treat transaction simulation as a prerequisite for sending assets. Remember that while the agent can provide technical guidance on gas and nonces, it cannot undo a transaction once it is mined. Be particularly cautious with token approvals; always prefer limited approvals over unlimited ones. When using L2 bridges, ensure you understand the difference between native bridge finality and third-party liquidity exit times, as liquidity provider risks are real. Use MEV-protecting RPCs whenever interacting with public DEX pools to prevent sandwich attacks.
