clawcast

What This Skill Does

The clawcast skill empowers your OpenClaw agent to act as a sophisticated EVM (Ethereum Virtual Machine) transaction assistant. Built on top of the powerful cast CLI from the Foundry toolkit, this skill provides a structured interface for managing cryptocurrency wallets, interacting with various blockchain networks, and executing transactions safely. Rather than forcing users to memorize complex command-line arguments, clawcast provides an interactive, step-by-step onboarding flow. It intelligently handles keystore creation, secure password management, and network configuration by referencing localized asset files (evm-networks.json and evm-network-tokens.json). By automating the setup of RPC endpoints and validation of wallet states, this skill ensures the agent can reliably fetch balances, verify network connectivity, and provide accurate explorer links for any supported EVM-compatible chain.

Installation

To integrate this capability into your agent workspace, execute the following command in your terminal: clawhub install openclaw/skills/skills/tezatezaz/clawcast Once installed, immediately initialize your TOOLS.md documentation to include a summary of this skill, ensuring your agent workspace remains organized and the skill remains discoverable for future automation tasks.

Use Cases

• Guided Onboarding: Use the step-by-step script series (01_install_cast.sh through 06_finish.sh) to securely set up an agent-controlled wallet from scratch, including encryption and key storage.
• Transaction Monitoring: Use scripts/check_wallet.sh and scripts/show_network.sh to provide real-time status updates on wallet health and active network connectivity.
• Network Switching: Seamlessly pivot between Ethereum, Layer 2s, or testnets by updating the local environment state based on the predefined authoritative network assets.
• Secure Cleanup: Perform safe wallet disposal using scripts/remove_wallet.sh when a session or project concludes, ensuring sensitive keys and local environment variables are purged correctly.

Example Prompts

• "I'd like to start using clawcast to set up a new wallet for interacting with the Optimism network. Can you guide me through the onboarding process?"
• "Can you check the current health of my connected wallet and tell me which network the agent is currently pointing to?"
• "I'm done with this testing phase. Please guide me through the process of securely removing my wallet and clearing the local configuration files."

Tips & Limitations

The clawcast skill is designed for interactive, conversational use. Avoid attempting to run the underlying onboarding scripts in parallel; the agent works best when following the provided single-step confirmation loop. Always prioritize the security of your private keys and mnemonics, ensuring they are only entered when prompted by the script interface. Note that the skill relies on Foundry/cast being available on your system path; if installation fails, verify your environment dependencies first. Because this tool handles sensitive cryptographic data, always review the audit status provided in the skill metadata to ensure you are operating with the latest secure version.
