onchain

What This Skill Does

The Onchain CLI is a powerful utility designed for OpenClaw users to interact with blockchain data, decentralized finance (DeFi) protocols, and centralized exchanges (CEX) directly from the command line. It acts as an abstraction layer over major blockchain explorers and market data providers, allowing you to fetch real-time token prices, analyze complex transaction histories, monitor wallet balances, and track your holdings across multiple chains, including Ethereum, Solana, Polygon, Arbitrum, and more. Whether you are a casual user tracking your crypto portfolio or a developer auditing transaction hashes, this tool provides a unified interface to access fragmented on-chain and off-chain data.

Installation

To integrate this skill into your environment, use the OpenClaw command: clawhub install openclaw/skills/skills/arein/onchain

Once installed, you must perform the mandatory setup. Run onchain setup to initialize your API keys for services like Coinbase, Binance, DeBank, and Helius. Once configured, verify your installation by running onchain test. If you skip the setup, you will be limited to public market data only.

Use Cases

• Portfolio Management: View your net worth and current asset allocation across cold storage wallets and centralized exchanges.
• Transaction Auditing: Quickly inspect the details of failed or successful transactions using hashes or block explorer links.
• Market Analysis: Stay updated on live token prices and network congestion using real-time gas fee tracking.
• DeFi Tracking: View staked positions, liquidity pools, and yield farming balances without navigating to multiple DApps.

Example Prompts

1. "What is the current price of Ethereum and what are the gas fees on Polygon right now?"
2. "Show me the balance of my wallet 0x123... and list my last five transactions."
3. "Check my recent trade history on Coinbase and compare it to my current portfolio value."

Tips & Limitations

Always run onchain test if you encounter "API key required" errors. Remember that the skill's ability to view your assets is strictly limited by the API keys provided during setup. If an asset is not supported by your DeBank or Helius provider, it may not appear in the portfolio command. Always double-check transaction hashes before executing actions based on their status.
