cow-swap

What This Skill Does

The cow-swap skill integrates the CoW Protocol directly into the OpenClaw agent environment, providing users with a robust, MEV-protected decentralized exchange (DEX) aggregator. By utilizing batch auctions, the skill ensures that trades are shielded from front-running and sandwich attacks, which are common issues in standard decentralized trading. A standout feature of this skill is its ability to facilitate 'Coincidence of Wants' (CoWs), where trades are matched peer-to-peer, often resulting in superior execution prices. Furthermore, the skill supports surplus sharing, meaning that if the execution price is better than the quoted price, the user receives the difference. It includes a built-in, transparent 0.5% partner fee mechanism for development support, making it an excellent choice for users looking for high-quality, professional-grade trading execution within their AI workflows.

Installation

To integrate the CoW Swap skill into your OpenClaw agent, execute the following command in your terminal within your OpenClaw workspace:

clawhub install openclaw/skills/skills/0xterrybit/cow-swap

Ensure that you have your EVM wallet credentials and environment variables correctly configured to allow the agent to authorize transactions on your behalf. Once installed, the skill will be automatically indexed by your agent, allowing you to trigger swaps through natural language prompts.

Use Cases

• Automated Portfolio Rebalancing: Trigger automated token swaps to maintain target portfolio allocations across Ethereum, Gnosis, Arbitrum, or Base networks.
• MEV-Resistant Large Trades: Execute significant volume orders without worrying about slippage caused by malicious MEV bots.
• Yield Management: Swap rewards from liquidity mining or staking directly into stablecoins or other assets in a single, gas-efficient batch transaction.
• Decentralized Dollar-Cost Averaging (DCA): Schedule regular, automated trades that take advantage of the protocol's batch auction mechanics.

Example Prompts

• "CoW Swap 1 ETH to USDC on mainnet using the best available price and ensure MEV protection is active."
• "Using the cow-swap skill, create an order to trade 5000 USDC for WETH on the Arbitrum chain."
• "What is the current quoted price for swapping 0.5 WBTC to DAI on the Gnosis chain via CoW Swap?"

Tips & Limitations

• Transparency: The skill explicitly includes a 0.5% partner fee to support ongoing development; this is factored into your quote calculations.
• Gasless Orders: One of the main advantages is the ability to submit orders without needing the native gas token for the transaction itself, as the fee is deducted from the swap output.
• Chain Support: Ensure you specify the correct chain context (mainnet, gnosis, arbitrum, or base) to avoid routing errors.
• Time Sensitivity: Quotes are time-bound. Always ensure that the validTo parameter in your order creation is set to a reasonable duration to prevent order expiration before the batch auction is processed.
