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 stanah/dotagents at 4f1efc7e2c.

    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 Solidity smart contracts to interact with and transfer data across different blockchain networks. It facilitates cross-chain communication, allowing for actions like bridging assets or triggering events on a remote chain based on conditions met on the originating chain. This capability is crucial for building decentralized applications (dApps) that operate seamlessly across multiple blockchains.

When to use it

  • Asset Bridging: Transferring tokens or NFTs between different blockchain networks, such as moving ERC-20 tokens from Ethereum to Polygon.
  • Cross-Chain Oracles: Fetching data from one chain and using it to trigger actions on another (e.g., settling a futures contract).
  • Decentralized Exchanges (DEXs): Enabling trading of assets across multiple chains, expanding liquidity pools.
  • Interoperable dApps: Building applications that leverage functionalities or data available only on specific blockchains.

Key capabilities

  • Cross-chain message passing
  • Smart contract interaction across networks
  • Asset bridging functionality
  • Event triggering on remote chains

Example prompts

  • "Bridge 10 ETH from Ethereum to Binance Smart Chain."
  • "Execute this function on the Polygon chain when a specific event occurs on the Ethereum chain."
  • "Check the balance of my token on Avalanche based on its representation on Ethereum."

Tips & gotchas

  • Requires familiarity with Solidity and blockchain concepts.
  • Cross-chain operations can be complex and may involve transaction fees on multiple networks.
