Query Onchain Data

Official
coinbase·vlatest·other·MIT

Helps with querying, data as part of agent workflows workflows.

Repository

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

This skill enables AI agents to retrieve and analyze on-chain data from blockchain networks. It provides access to real-time information such as transaction details, wallet balances, smart contract events, and network statistics.

When to use it

  • To verify the status of a cryptocurrency transaction.
  • For auditing or monitoring blockchain activity related to a specific address.
  • When building decentralized applications that require on-chain data integration.
  • To generate reports based on historical blockchain data for analysis purposes.

Key capabilities

  • Querying blockchain transactions and addresses
  • Accessing real-time network statistics
  • Retrieving smart contract event logs
  • Supporting multiple blockchain networks

Example prompts

  • "Check the balance of wallet address 0x123456789abcdef..."
  • "Show me all transactions made by this account in the last 24 hours."
  • "Get the latest Ethereum network statistics and block count."

Tips & gotchas

  • Ensure that the AI agent has access to a reliable blockchain explorer or API for accurate data retrieval.
  • Some on-chain queries may be limited by blockchain network constraints, such as rate limits or data availability.
