What is Nansen Wallet?
Nansen Wallet is a specialized utility designed for developers and automated agents to manage cryptocurrency assets with high security and precision. It provides a comprehensive interface for creating, listing, and exporting wallets while ensuring all private data is protected via AES-256-GCM encryption. This tool is a critical component for those building financial automations using Openclaw Skills, allowing for seamless interaction with both EVM-compatible chains and Solana.
The skill emphasizes a security-first approach, particularly regarding password management. It is designed to work in headless environments where credentials must be persisted securely in local environment files rather than being held in volatile session memory. This ensures that funds remain accessible and secure across session restarts, making it an ideal choice for persistent AI-driven financial agents.
Nansen Wallet Use Cases
- Programmatic creation and management of multiple blockchain wallets.
- Automating token transfers and balance checks on Ethereum, BSC, and Solana.
- Performing dry-run transaction previews to validate logic before broadcasting to the blockchain.
- Integrating secure wallet operations into broader Openclaw Skills workflows for DeFi and asset tracking.
How Nansen Wallet Works
- The user authenticates the CLI using a Nansen API key to enable blockchain communication.
- A persistent encryption password is generated and stored in a secure local environment file (~/.nansen/.env).
- New wallets are created and encrypted using the AES-256-GCM standard, ensuring the private keys are never stored in plain text.
- For any transaction or wallet operation, the skill sources the secure environment file to unlock the required credentials.
- The skill executes the requested command—such as sending tokens or exporting a key—across the specified blockchain network (EVM or Solana).
Nansen Wallet Setup
To get started with this skill, ensure you have the Nansen CLI installed and your API credentials ready. Follow these steps to initialize the environment for Openclaw Skills:
# Install the necessary package
npm install -g nansen-cli
# Authenticate with your API key
nansen login
# Configure the secure password environment
mkdir -p ~/.nansen
if ! grep -q 'NANSEN_WALLET_PASSWORD' ~/.nansen/.env 2>/dev/null; then
NANSEN_WALLET_PASSWORD=$(openssl rand -base64 24)
echo "export NANSEN_WALLET_PASSWORD=\"$NANSEN_WALLET_PASSWORD\"" >> ~/.nansen/.env
chmod 600 ~/.nansen/.env
fi
Nansen Wallet Data Schema & Taxonomy
The skill organizes its configuration and security metadata as follows:
| Item | Storage Type | Description |
|---|---|---|
NANSEN_API_KEY |
Environment Var | Used for authenticating API requests to Nansen services. |
NANSEN_WALLET_PASSWORD |
Local File (.env) |
AES-256-GCM encryption key for local wallet storage. |
| Wallet Metadata | Encrypted Local Store | Stores the encrypted private keys and public addresses. |
| RPC Endpoints | Configurable Var | Optional custom endpoints for EVM (NANSEN_EVM_RPC) and Solana (NANSEN_SOLANA_RPC). |
Nansen Wallet Advanced Features
- Multi-chain support covering both Solana and the entire EVM ecosystem.
- Dry-run mode for transaction simulation, preventing accidental fund transfers during development.
- Max-send functionality to easily sweep entire wallet balances to a destination.
- Strict password policy implementation designed specifically for AI agents to prevent credential leakage in conversation logs.
