What it does

Nansen Wallet Manager is an agent skill from nansen-ai/nansen-cli. Wallet management — create (local or Privy server-side), list, show, export, send, delete. Use when creating wallets, checking balances, or sending tokens.

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Backend development. The licence is MIT.

When your agent uses it

Creating wallets
Checking balances

Example prompts

“/nansen-wallet-manager”

Requirements

A credential in NANSEN_API_KEY
A credential in PRIVY_APP_SECRET
Pre-approved tools (allowed-tools): Bash(nansen:*)

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

NANSEN_WALLET_PASSWORD env var (if set)
OS keychain (saved automatically on wallet create)
~/.nansen/wallets/.credentials file (insecure fallback, with warning)
Structured JSON error with instructions (if none available)

What it can do on your machine

Read from SKILL.md and the folder at commit d097942. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Bash(nansen:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- NANSEN_WALLET_PASSWORD
- PRIVY_APP_SECRET
- NANSEN_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Nansen Wallet Manager loads about 2.1k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 807 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~44
When it runs · the whole SKILL.md, loaded when a task matches: ~2.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.

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

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 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)

NANSEN_WALLET_PASSWORD env var (if set)
OS keychain (saved automatically on wallet create)
~/.nansen/wallets/.credentials file (insecure fallback, with warning)
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

# Default is REDACTED — shows addresses only, never private keys
nansen wallet export <name>

# Write private keys to a file only the owner can read (0600, refuses to overwrite)
nansen wallet export <name> --file <path>

# Print private keys in plaintext to stdout (explicit acknowledgement required;
# warns on stderr when stdout is an interactive terminal)
nansen wallet export <name> --reveal

# Password auto-resolved from keychain (needed for --reveal / --file)
nansen wallet delete <name>

Prefer --file over --reveal: plaintext on stdout ends up in terminal scrollback, shell logs, and agent transcripts.

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)
`--reveal`	Export only: print private keys in plaintext to stdout (required acknowledgement)
`--file`	Export only: write private keys to this path (created 0600, refuses to overwrite)
`--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 (can also be saved via `nansen login --human`)
`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
