nansen-wallet_skill

Overview

This skill provides command-line wallet management for creating, listing, inspecting, exporting, sending, and deleting encrypted wallets. It automates secure password generation and persistence, and supports EVM and Solana chains with dry-run and max-send options. Use it to manage multiple wallets, check balances, and perform token transfers from a consistent, scripted interface.

How this skill works

The skill wraps nansen wallet commands and enforces a password persistence workflow: generate or reuse NANSEN_WALLET_PASSWORD stored in ~/.nansen/.env and source it before any operation. It exposes commands to create wallets, list and show details, set a default wallet, export or delete keys, and send native tokens with flags for chain, amount, max, and dry-run. Network endpoints and API key are configurable through environment variables for EVM and Solana RPCs.

When to use it

• Creating a new encrypted wallet and setting a persisted password
• Listing available wallets or viewing a wallet’s details and default status
• Sending native tokens on EVM or Solana networks with optional dry-run
• Exporting or deleting a wallet from local storage
• Scripting wallet operations in CI or automation where env-based secrets are required

Best practices

• Always persist NANSEN_WALLET_PASSWORD to ~/.nansen/.env before any wallet command — never rely on ephemeral memory
• Do not display or log the wallet password; source the env file in-shell instead
• If ~/.nansen/.env exists, reuse the existing password; never overwrite it
• Use --dry-run to preview transactions before broadcasting, and --max carefully when sending entire balance
• Restrict permissions on ~/.nansen/.env (chmod 600) and back it up securely if needed

Example use cases

• Initialize automated workflows that create and fund wallets for testing across Ethereum and Solana
• Quickly list and inspect wallet addresses and balances during audits or operational checks
• Send a precise amount or the entire native balance to another address, with a dry-run to validate gas and fees
• Export a wallet to move keys to a hardware wallet or secure backup
• Delete ephemeral wallets created for short-lived tasks
