# nansen-wallet-manager A skill for managing crypto wallets through the nansen CLI: create, list, show, send tokens, export. Useful when an agent needs to handle a wallet from the terminal. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 366 installs · ★ 139 - Author: nansen-ai - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/nansen-ai/nansen-cli/tree/HEAD/skills/nansen-wallet-manager/SKILL.md - Updated: 2026-10-22 - HTML: https://affpapa.org/en/nevibecode/skills/nansen-wallet-manager ## What it does The skill tells an agent how to work with wallets through the `nansen` CLI. Two providers are supported: local (the default) keeps keys encrypted on disk and needs a password of at least 12 characters, while Privy stores keys server-side and needs no password. Every other operation — `list`, `show`, `send`, `delete`, `default` — behaves the same for both. For a local wallet the password has to come from a human. The agent must not invent it or keep it in files or conversation history. After creation the CLI saves the password to the OS keychain, and when no keychain exists it falls back to `~/.nansen/wallets/.credentials` and warns on every operation. You can move to secure storage later with `nansen wallet secure`. Export shows addresses only by default. Keys come out with `--reveal` or get written to a file with 0600 permissions via `--file`. The README suggests `--file`: plaintext on stdout ends up in terminal scrollback and agent transcripts. Privy wallets cannot be exported at all — the provider holds the keys. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add nansen-ai/nansen-cli --skill nansen-wallet-manager -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/nansen-wallet-manager/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/nansen-wallet-manager/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add nansen-ai/nansen-cli --skill nansen-wallet-manager -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/nansen-wallet-manager/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add nansen-ai/nansen-cli --skill nansen-wallet-manager -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/nansen-wallet-manager/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install nansen-ai/nansen-cli nansen-wallet-manager ``` 2. **Manually: put the files in place** - File: `.github/skills/nansen-wallet-manager/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add nansen-ai/nansen-cli --skill nansen-wallet-manager -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/nansen-ai/nansen-cli --path skills/nansen-wallet-manager ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/nansen-wallet-manager/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add nansen-ai/nansen-cli --skill nansen-wallet-manager -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/nansen-ai/nansen-cli/tree/HEAD/skills/nansen-wallet-manager/SKILL.md ## When to use it - create a local wallet with a password from the user - create a server-side Privy wallet without a password - list wallets and check balances - send a native token to an address on Solana or EVM - dry-run a transfer without broadcasting it ## Example prompts - create a local wallet named trading - show the balance of the trading wallet - send 1.5 SOL to from the trading wallet ## Source text · SKILL.md · MIT Below is the content of a third-party file.

Run `nansen auth status` for offline selection. Cached access expiry alone permits automatic renewal during an authorized task. Stop on anonymous selection, invalid state, blocked/uncertain renewal or actual auth failure; never drop a credential or fall back to anonymous x402 payment. Browser login does not grant wallet signing, privileged service identity or a persistent MCP integration key. Preserve all confirmation, signing, sanctions and geographic checks below. Browser login is available in CLI 2.0.0 within the [macOS arm64 preview scope](https://github.com/nansen-ai/nansen-cli/blob/main/docs/browser-login.md#preview-platform-scope). # Wallet ## Auth Setup Use a selected nansen:api browser session or conventional API key for Nansen account API calls. Agents should inject `NANSEN_API_KEY` through their environment or secret manager and use commands directly; no login is needed to persist it. Human terminal users can use explicit `nansen login --human` for legacy key setup. With an already injected environment key, that explicit mode saves it without prompting and requires the native auth lock binding. ```bash # Free live check of the effective API credential nansen account ``` Plain `nansen login` instead requests fresh browser approval. It does not save an environment key or grant wallet signing/RPC authority. Wallet custody and provider credentials below remain separate. ## Wallet Providers The CLI supports two wallet providers: | | **Local** (default) | **Privy** (server-side) | |---|---|---| | Key storage | Encrypted on disk | Server-side via Privy API | | Password required | Yes (min 12 chars) | No | | Export private keys | Yes (`wallet export`) | No — keys are managed by Privy | | Best for | Human users, manual trading | Agents, automated workflows | | Flag | `--provider local` (default) | `--provider privy` | | Required env vars | `NANSEN_WALLET_PASSWORD` | `PRIVY_APP_ID` + `PRIVY_APP_SECRET` | ## Privy Wallet Creation ```` END THIRD-PARTY FILE 62113d74fa1faba9 The third-party file has ended.
