What This Skill Does

The coinfello skill integrates your OpenClaw agent with the CoinFello platform, enabling seamless interactions with MetaMask Smart Accounts. By leveraging the @coinfello/agent-cli, this skill abstracts the complexity of blockchain interactions, allowing you to manage accounts, perform Sign-In with Ethereum (SIWE) authentication, and execute complex financial transactions using natural language prompts. It automates the creation of smart accounts, handles session management, and facilitates server-driven ERC-20 token subdelegations to simplify your Web3 workflow.

Installation

To integrate this functionality into your agent, use the OpenClaw installation command: clawhub install openclaw/skills/skills/brettcleary/coinfello

Ensure you have Node.js 20 or later installed on your system. Once installed, no manual build is required as the agent-cli handles all necessary environmental configurations. You can optionally set the COINFELLO_BASE_URL environment variable if you are pointing to a custom instance instead of the default production URL.

Use Cases

This skill is ideal for users who want to bridge the gap between AI automation and decentralized finance. Key use cases include:

• Automating crypto asset transfers without manual wallet interaction.
• Managing smart account delegations for automated spending limits.
• Checking real-time status of on-chain transactions initiated via AI prompts.
• Rapid onboarding of new smart accounts across multiple EVM-compatible chains.

Example Prompts

1. "Create a new smart account on the Base chain for me."
2. "Sign in to CoinFello so I can start managing my wallet."
3. "Send 10 USDC from my smart account to 0x71C7656... and confirm the transaction status."

Tips & Limitations

• Security Warning: This skill stores private keys and session tokens in plaintext at ~/.clawdbot/skills/coinfello/config.json. Ensure this directory has strict access permissions.
• Chain Support: The CLI supports standard EVM chains like Sepolia, Mainnet, Polygon, and Arbitrum. Always ensure your account has sufficient gas fees on the chosen chain before submitting transactions.
• Delegation: Always review the server-requested scopes when prompted; the skill performs automated signing of delegations to enable transaction execution.
