A command-line wallet manager for AI agents on Monad, a blockchain network. It creates wallets, signs Sign-In with Ethereum messages, and manages MON token balances for the Nad ecosystem.

Use it to create or manage a Monad wallet, sign authentication messages, check MON balances, or connect to services such as NadMail, NadName, and nad.fun.

It lets an agent use a Monad identity without a browser extension or manual wallet steps. It also documents safer handling of private keys through environment variables and restricted wallet files.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add dAAAb/agent-skills --skill nad-wallet

Clone the repo

git clone --depth 1 https://github.com/dAAAb/agent-skills

Made for: Claude Code, Codex.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00045	$0.02541
Opus 5.5	$0.00018	$0.01016
Sonnet 5.5	$0.00009	$0.00508
Haiku 4.5	$0.00005	$0.00254

Security

Grade B, and why

nad-wallet scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/check-balance.js, scripts/create-wallet.js, scripts/nadmail-register.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

🔐 Nad Wallet - Monad Chain Identity for AI Agents

Every autonomous agent needs a wallet on Monad. Create one without human help.

TL;DR: Programmatic wallet creation on Monad blockchain. SIWE auth for NadMail, MON balance checks, ecosystem integration.

Why Nad Wallet?

Monad Native — Built specifically for Monad blockchain (Chain ID 143)
True Autonomy — Your agent creates and controls its own wallet
No Browser Needed — Pure CLI, no extensions or popups
Nad Ecosystem Ready — NadMail, NadName, nad.fun integration
SIWE Ready — Sign-In with Ethereum for Web3 services
Secure by Default — Environment variables, no plaintext keys

Create and manage Monad chain wallets programmatically for the Nad ecosystem.

⚠️ Security First

✅ DO	❌ DON'T
Use NAD_PRIVATE_KEY environment variable	Store private keys in plain text files
Set wallet files to chmod 600	Commit wallet files to git
Use `--env` mode (recommended)	Use `console.log(privateKey)`
Back up mnemonics offline	Share private keys or mnemonics
Store files in `~/.nad-wallet/` only	Auto-detect wallets outside ~/.nad-wallet/

🔒 Security Standards: Identical to Base Wallet security practices but adapted for Monad/Nad ecosystem.

Network Information

Property	Value
Blockchain	Monad
Chain ID	143
RPC URL	https://rpc.monad.xyz

Native Token	MON
Ecosystem	nad.fun, NadMail, NadName

Quick Start

Create a New Wallet (Recommended)

# Output as environment variable format (safest)
node scripts/create-wallet.js --env

# Output example:
# export NAD_WALLET_ADDRESS="0x..."
# export NAD_PRIVATE_KEY="0x..."

Then copy to your shell or .env file.

Create with File Storage (Opt-in)

# Only if you need file-based storage
node scripts/create-wallet.js --managed my-agent

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

nad-wallet is a skill published in the GitHub repository dAAAb/agent-skills (3 stars, last pushed 1mo ago), licensed MIT. It adds 45 tokens to every session and 2,541 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
