pinion-wallet

pinion-wallet is a skill for Claude Code from chu2bard/pinion-os. It costs 32 tokens per session (320 once invoked), scanned A, original, MIT.

A tool that creates a new Ethereum wallet for the Base network, returning its public address and private key.

In plain words
What is it for?
Use it to bootstrap an agent wallet, create a temporary wallet for a separate task, or get an address that can receive funds.
Why use it?
It removes the need to generate wallet keys yourself when starting an agent or isolating a task. The private key is shown only once, so it must be stored safely.

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.

Security

Grade A, and why

pinion-wallet scanned grade A 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 6d ago.

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.

What it actually says

Wallet Generation

Generates a cryptographically secure Ethereum keypair for the Base network. Returns the address and private key.

Endpoint

GET https://pinionos.com/skill/wallet/generate

Price: $0.01 USDC per call (x402 on Base)

Parameters

None.

Example Request

curl https://pinionos.com/skill/wallet/generate

The first request returns HTTP 402 with payment requirements. Sign a USDC TransferWithAuthorization (EIP-3009) and retry with the X-PAYMENT header.

Example Response

{
  "address": "0x7a21...",
  "privateKey": "0x4b3f...",
  "network": "base",
  "chainId": 8453,
  "note": "Fund this wallet with ETH for gas and USDC for x402 payments. Keep the private key safe.",
  "timestamp": "2026-02-16T12:00:00.000Z"
}

When to Use

  • Bootstrap a new agent wallet on Base.
  • Create disposable wallets for isolated agent tasks.
  • Generate a receiving address for incoming funds.

Security

The private key is returned once. Store it securely. Anyone with the key controls the wallet.

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.
