What This Skill Does

The Nansen Wallet skill provides a comprehensive suite of tools for managing cryptocurrency wallets directly within the OpenClaw environment. It is designed to handle the full lifecycle of wallet operations, including secure creation, balance tracking, token transfers, and configuration management. By integrating Nansen's research and wallet capabilities, the skill allows agents to programmatically interact with EVM and Solana chains, ensuring that financial operations can be automated with security as a primary consideration.

Installation

You can install the skill by running the following command in your terminal: clawhub install openclaw/skills/skills/hurcannansen/nansen-wallet

Ensure you have completed the initial authentication by running nansen login. Before performing any wallet actions, verify that your environment is prepared by creating the ~/.nansen directory and initializing the NANSEN_WALLET_PASSWORD environment variable within ~/.nansen/.env as outlined in the documentation.

Use Cases

• Automated Portfolio Management: Regularly check balances across different chains to trigger automated reports or rebalancing strategies.
• Asset Transfers: Programmatically send native tokens to specific addresses for dApp interactions or cross-chain liquidity management.
• Secure Key Handling: Utilize the automated password persistence system to ensure wallet encryption is handled safely without storing sensitive credentials in volatile agent memory.
• Pre-flight Validation: Use the --dry-run flag to simulate transactions before execution to avoid costly errors or failed gas submissions.

Example Prompts

• "List all available wallets and show me the balance for my default ethereum wallet."
• "Send 0.5 ETH to 0x123...abc to cover the gas for the next batch of transactions."
• "Create a new Solana wallet, show the address, and save it as my primary wallet for solana interactions."

Tips & Limitations

• Security First: Never store passwords in conversation history. The skill strictly enforces an AES-256-GCM encryption standard, requiring passwords to be persisted in ~/.nansen/.env. Always verify file permissions using chmod 600 to prevent unauthorized access.
• Environment Sourcing: Always prepend source ~/.nansen/.env to your commands. This ensures that the agent correctly recognizes your wallet password and RPC configurations.
• RPC Configuration: If you encounter connection issues, you can override default behavior by setting the NANSEN_EVM_RPC or NANSEN_SOLANA_RPC environment variables to use your preferred node provider.
