Install on your platform

Showing Claude Code. One command installs this skill into any of the agents below.

Installs under a different name. Its SKILL.md names it agentic-wallet, not the name it is listed under, so the command below uses that name.
  1. 1

    Run this in your project

    terminal
    $ npx skills add coinbase/agentic-wallet-skills --skill agentic-wallet -a claude-code

  2. Uses the open-source skills CLI and needs Node.js. Add -g to install it for your user instead of this project.

Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned coinbase/agentic-wallet-skills at 70cb79c85f.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

The x402 skill enables AI agents to interact with blockchain-based wallets, allowing them to perform actions such as checking balances, sending transactions, and managing cryptographic keys securely. It is designed for use within the Coinbase ecosystem, providing a bridge between AI agents and decentralized finance (DeFi) applications.

When to use it

  • When an AI agent needs to send cryptocurrency from a user's wallet to another address.
  • To fetch real-time balance information of a blockchain account for reporting or decision-making purposes.
  • For managing private keys securely within an AI-driven financial application.

Key capabilities

  • Securely interact with blockchain wallets
  • Send and receive cryptocurrency transactions
  • Retrieve account balances in real time

Example prompts

  • "Send 0.5 ETH from wallet address 0x1234... to 0x5678..."
  • "Check the current balance of the Ethereum account 0x9ABC..."
  • "Generate a new cryptographic key pair for secure wallet access"

Tips & gotchas

  • Ensure that private keys and sensitive information are handled with strict security protocols.
  • This skill is specifically optimized for use within the Coinbase ecosystem, so compatibility may vary with other blockchain platforms.
