onchain
CLI for crypto portfolio tracking, market data, and CEX history. Use when the user asks about crypto prices, wallet balances, portfolio values, Coinbase/Binance holdings, or Polymarket predictions.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/arein/onchain-testWhat This Skill Does
The onchain skill provides a powerful command-line interface for the OpenClaw agent to interact with decentralized finance, centralized exchanges, and prediction markets. It acts as a bridge between the agent and various blockchain networks, allowing for real-time retrieval of token prices, detailed wallet audits, and portfolio tracking across both EVM-compatible chains and the Solana ecosystem. By abstracting the complexity of API interactions with services like DeBank and Helius, this skill enables the agent to act as a financial assistant, providing concise, actionable data directly to the user.
Installation
To integrate this skill into your OpenClaw environment, ensure you have your API keys ready. Use the following command in your terminal:
clawhub install openclaw/skills/skills/arein/onchain-test
After installation, you must run onchain setup to configure your API keys. The skill relies on keys for DeBank (EVM), Helius (Solana), and your preferred CEX (Coinbase or Binance). Ensure these are securely stored in your environment or configuration file.
Use Cases
This skill is designed for scenarios where the agent needs to provide financial intelligence. Common use cases include: monitoring the current market price of volatile assets, verifying the holdings of specific crypto addresses, tracking DeFi positions across multiple chains, viewing historical trade data from centralized exchanges, and exploring ongoing prediction markets on Polymarket. It is particularly effective for users who manage cross-chain portfolios and require a unified view of their financial health.
Example Prompts
- "OpenClaw, check the current price of Ethereum and show me my total balance on my main wallet."
- "What are the trending prediction markets on Polymarket right now?"
- "Summarize my recent trade history from my connected Binance account."
Tips & Limitations
To get the most accurate data, always use the --json flag when passing output to other agent tools or scripts to ensure data integrity. Note that this skill is strictly a read-heavy tool; while it can pull comprehensive portfolio data, ensure you are aware of your API rate limits, especially with free tiers on providers like CoinGecko. Always store your sensitive keys in the designated ~/.config/onchain/config.json5 file and never share this file. If you encounter missing data for a specific chain, ensure that your DeBank or Helius keys are correctly configured and have the necessary permissions enabled.
