MetaMask OpenClaw Wallet Integration

Skill by ara.so — Hermes Skills collection.

Overview

OpenClaw is a safety-first TypeScript toolkit and SDK for integrating MetaMask wallets into dapps. Built on the official MetaMask SDK, it provides a clean API for:

• Connecting wallets (desktop browser, mobile browser, QR code to MetaMask Mobile)
• Reading account balances across EVM chains (Ethereum, Polygon, Base, Arbitrum, Optimism, Linea)
• Signing messages (user approves in MetaMask UI)
• Preparing and sending transactions (user approves amount and gas)
• Switching networks with automatic chain addition
• Reacting to account/network changes

Safety guarantee: OpenClaw never requests or handles seed phrases or private keys. All sensitive operations require user approval in the MetaMask UI.
