--- name: nansen-wallet-manager description: Wallet management — create (local or Privy server-side), list, show, export, send, delete. Use when creating wallets, checking balances, or sending tokens. metadata: openclaw: requires: env: - NANSEN_API_KEY bins: - nansen primaryEnv: NANSEN_API_KEY install: - kind: node package: nansen-cli bins: [nansen] allowed-tools: Bash(nansen:*) --- # Wallet ## Auth Setup ```bash # Save API key (non-interactive) nansen login --api-key <key> # Or via env var: NANSEN_API_KEY=<key> nansen login # Verify nansen research profiler labels --address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 --chain ethereum ``` ## 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 Privy wallets are server-side wallets managed by the Privy API. No password is needed — keys never touch the local machine. ### Prerequisites The following environment variables must be set: | Var | Purpose | |-----|---------| | `PRIVY_APP_ID` | Privy application ID | | `PRIVY_APP_SECRET` | Privy application secret | ### Create a Privy wallet ```bash nansen wallet create --provider privy # Or with a custom name: nansen wallet create --name agent-wallet --provider privy ``` ### Critical rules for agents (Privy) - **No password needed** — Privy manages keys server-side - **Cannot export keys** — `wallet export` only works for local wallets - All other operations (`list`, `show`, `send`, `delete`, `default`) work identically for both providers ## Local Wallet Creation (Two-Step Agent Flow) > This section covers **local** wallet creation. For Privy server-side wallets, see the [Privy Wallet Creation](#privy-wallet-creation) section above — no password is needed. Wallet creation requires a password from the **human user**. The agent must NOT generate or store the password itself. > **Step 1 (Agent → Human):** Ask the user to provide a wallet password (minimum 12 characters). > > **Step 2 (Agent executes):** Run the create command with the password the user gave you. ```bash NANSEN_WALLET_PASSWORD="<password_from_user>" nansen wallet create ``` After creation, the CLI automatically saves the password: - **OS keychain** (macOS Keychain, Linux secret-tool, Windows Credential Manager) — secure, preferred - **~/.nansen/wallets/.credentials file** — insecure fallback when no keychain is available (e.g. containers, CI) **All future wallet operations retrieve the password automatically** — no env var or human input needed. If the `.credentials` file fallback is used, the CLI prints a warning on every operation. To migrate to secure storage later, run `nansen wallet secure`. ### Password resolution order (automatic) 1. `NANSEN_WALLET_PASSWORD` env var (if set) 2. OS keychain (saved automatically on wallet create) 3. `~/.nansen/wallets/.credentials` file (insecure fallback, with warning) 4. Structured JSON error with instructions (if none available) ### Critical rules for agents - **NEVER generate a password yourself** — always ask the human user - **NEVER store the password** in files, memory, logs, or conversation history - **NEVER use `--human` flag** — that enables interactive prompts which agents cannot handle - After wallet creation, you do NOT need the password for future operations — the keychain handles it - If you get a `PASSWORD_REQUIRED` error, ask the user to provide their password again ## Create ### Privy (server-side, no password) ```bash nansen wallet create --provider privy # Or with a custom name: nansen wallet create --name trading --provider privy ``` Requires `PRIVY_APP_ID` + `PRIVY_APP_SECRET` env vars. No password needed. ### Local (encrypted on disk, password required) ```bash # Ask the user for a password first, then: NANSEN_WALLET_PASSWORD="<password_from_user>" nansen wallet create # Or with a custom name: NANSEN_WALLET_PASSWORD="<password_from_user>" nansen wallet create --name trading ``` ## List & Show ```bash nansen wallet list nansen wallet show <name> nansen wallet default <name> ``` ## Send ```bash # Send native token (SOL, ETH) — password auto-resolved from keychain nansen wallet send --to <addr> --amount 1.5 --chain solana # Send entire balance nansen wallet send --to <addr> --chain evm --max # Dry run (preview, no broadcast) nansen wallet send --to <addr> --amount 1.0 --chain evm --dry-run ``` ## Export & Delete ```bash # Password auto-resolved from keychain nansen wallet export <name> nansen wallet delete <name> ``` ## Forget Password ```bash # Remove saved password from all stores (keychain + .credentials file) nansen wallet forget-password ``` ## Migrate to Secure Storage ```bash nansen wallet secure ``` For detailed migration steps (from `~/.nansen/.env`, `.credentials`, or env-var-only setups), see the **nansen-wallet-migration** skill. ## Flags | Flag | Purpose | |------|---------| | `--to` | Recipient address | | `--amount` | Amount to send | | `--chain` | `evm` or `solana` | | `--max` | Send entire balance | | `--dry-run` | Preview without broadcasting | | `--provider` | Wallet provider: `local` (default, encrypted on disk) or `privy` (server-side via Privy API) | | `--human` | Enable interactive prompts (human terminal use only — agents must NOT use this) | | `--unsafe-no-password` | Skip encryption (keys stored in plaintext — NOT recommended) | ## Environment Variables | Var | Purpose | |-----|---------| | `NANSEN_WALLET_PASSWORD` | Wallet encryption password — only needed for initial `wallet create`. After that, the OS keychain handles it. | | `NANSEN_API_KEY` | API key (also set via `nansen login --api-key <key>`) | | `PRIVY_APP_ID` | Privy application ID (required for `--provider privy`) | | `PRIVY_APP_SECRET` | Privy application secret (required for `--provider privy`) | | `NANSEN_WALLET_PROVIDER` | Default provider for wallet create — `local` or `privy` | | `NANSEN_EVM_RPC` | Custom EVM RPC endpoint | | `NANSEN_SOLANA_RPC` | Custom Solana RPC endpoint |
