wallet-integration

Purpose

This skill integrates blockchain wallets to enable secure cryptocurrency transactions, asset management, and key handling for networks like Ethereum and Bitcoin. It abstracts wallet interactions, ensuring secure key management and transaction signing.

When to Use

Use this skill when building applications that require wallet connectivity, such as dApps for token transfers, NFT management, or querying blockchain balances. Apply it in scenarios involving user authentication with wallets (e.g., MetaMask integration) or automated scripts for asset tracking.

Key Capabilities

• Connect to blockchain networks (e.g., Ethereum via RPC, Bitcoin via electrum) using private keys or mnemonic phrases.
• Perform transactions: Send ETH or BTC, including gas fee estimation for Ethereum.
• Manage assets: Query balances, list tokens, and handle multi-chain wallets.
• Secure key storage: Encrypt keys in memory and support hardware wallets like Ledger.
• Event listening: Subscribe to wallet events like incoming transactions via WebSocket.

Usage Patterns

Always initialize the wallet with a network and authentication method. Use environment variables for keys to avoid hardcoding. For CLI, prefix commands with claw wallet. In code, import the OpenClaw library and create a wallet instance. Handle asynchronous operations with async/await for network calls. Test integrations in a sandbox environment before production.
