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 failed 2 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 2 hosts that are neither well-known infrastructure nor declared in the skill's frontmatter: chainlist.org, foundry.paradigm.xyz.

    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.

About this skill

What it does

This skill allows interaction with Ethereum Virtual Machine (EVM)-compatible blockchains. It leverages the Foundry cast tool to perform actions such as retrieving account balances, executing contract functions, submitting transactions, and exploring blockchain data. The skill provides a convenient interface for developers and users needing direct blockchain interaction.

When to use it

  • Checking Account Balances: Quickly determine the ETH or token balance of an address on a supported EVM chain.
  • Contract Interaction: Call functions on deployed smart contracts, such as retrieving data or triggering actions.
  • Transaction Submission: Send transactions to the blockchain, for example, transferring tokens or interacting with DeFi protocols.
  • Blockchain Exploration: Retrieve transaction details and block information from the blockchain.

Key capabilities

  • Balance querying
  • Contract function calls
  • Transaction submission
  • Blockchain exploration using cast tool

Example prompts

  • "What is the ETH balance of address 0xAb5801a7D398d56A8cFC7F44461224CdcBb8B036?"
  • "Call the transfer function on contract 0xTenFifteenEightNineZeroSevenZeroEightSixZeroFourZeroOne with value 10000."
  • "Send 1 ETH from my address to 0xDeadbeefdeadbeefdeadbeefdeadbeefdeadbeef."

Tips & gotchas

  • Ensure you have Foundry installed and configured correctly, as this skill relies on the cast tool.
  • The skill’s functionality is limited by the capabilities of the underlying cast tool and supported EVM chains.
