# nansen-wallet-keychain-migration Migrates nansen-cli wallet passwords from plain text files and env vars into your OS keychain. Eliminates security warnings and verifies wallet decryption. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 352 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-keychain-migration/SKILL.md - Updated: 2026-10-22 - HTML: https://affpapa.org/en/nevibecode/skills/nansen-wallet-keychain-migration ## What it does The skill inspects current credential storage with `nansen auth status --pretty` and `nansen doctor --offline`. It checks whether the secret sits in `NANSEN_WALLET_PASSWORD`, a legacy `~/.nansen/.env` file, or a fallback `.credentials` file. When the password is already in the OS keychain, no changes are needed. The migration transfers the password to protected storage by running `nansen wallet secure`. The agent unsets the environment variable and validates decryption through a silent export test that checks the process exit code. Once confirmed, it deletes the insecure `~/.nansen/.env` file. On headless Linux systems without D-Bus or `secret-tool`, OS keychain operations fail immediately. If the password was completely lost, recovery is impossible because private keys are encrypted with AES-256-GCM. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add nansen-ai/nansen-cli --skill nansen-wallet-keychain-migration -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/nansen-wallet-keychain-migration/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/nansen-wallet-keychain-migration/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add nansen-ai/nansen-cli --skill nansen-wallet-keychain-migration -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/nansen-wallet-keychain-migration/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add nansen-ai/nansen-cli --skill nansen-wallet-keychain-migration -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/nansen-wallet-keychain-migration/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-keychain-migration ``` 2. **Manually: put the files in place** - File: `.github/skills/nansen-wallet-keychain-migration/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add nansen-ai/nansen-cli --skill nansen-wallet-keychain-migration -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/nansen-ai/nansen-cli --path skills/nansen-wallet-keychain-migration ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/nansen-wallet-keychain-migration/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add nansen-ai/nansen-cli --skill nansen-wallet-keychain-migration -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-keychain-migration/SKILL.md ## When to use it - move plain-text wallet passwords into the operating system keychain - diagnose insecure password storage using `nansen doctor` - verify AES-256-GCM wallet decryption via exit codes - purge obsolete credentials and environment files ## Example prompts - Help me migrate my nansen wallet password from .credentials into the OS keychain - I see a warning about an insecure password file, please secure my wallet in keychain - Check the current wallet password storage status and run nansen wallet secure ## Source text · SKILL.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE 905bb7ca61acd112 ````text --- name: nansen-wallet-keychain-migration description: Migrate an existing nansen-cli wallet from insecure password storage (env files, .credentials) to the new secure keychain-backed flow. metadata: openclaw: requires: bins: - nansen primaryEnv: NANSEN_API_KEY install: - kind: node package: nansen-cli bins: [nansen] allowed-tools: Bash(nansen:*) --- ## Authentication Nansen account API calls accept a selected `nansen:api` browser session or conventional API key with the same permissions. `NANSEN_API_KEY` takes precedence; optional `primaryEnv` preserves configured-key injection. 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 Migration — Old Flow to Secure Keychain Use this skill when a user already has a nansen-cli wallet set up with the **old** password storage method and wants to migrate to the new secure flow. ## When to use - User mentions they stored their password in `~/.nansen/.env`, a `.env` file, or `memory.md` - User gets the stderr warning: `⚠ Password loaded from insecure .credentials file` - User asks to "secure my wallet" or "migrate to keychain" - User created a wallet before the keychain update was released ## Detect current state `wallet show` only displays addresses and does NOT load or check the password. To detect the actual password situation, check the stored password source directly: ```bash # 1. Where is the password stored? Offline, decrypts nothing, prints no secrets nansen auth status --pretty # → x402.password.source: "env" | "keychain" | "file" | null # 2. Full setup check — flags the insecure .credentials file with a fix nansen doctor --offline # 3. Legacy pattern doctor does not cover: password written to ~/.nansen/.env ls -la ~/.nansen/.env 2>/dev/null && echo "FOUND: ~/.nansen/.env (insecure)" ``` Interpret `x402.password.source`: - `"file"` → password in `.credentials` file, needs migration (Path B) - `"keychain"` → already secure, no migration needed ```` END THIRD-PARTY FILE 905bb7ca61acd112 The third-party file has ended.
