Best for
  • AI agents that need unified operations across multiple EVM networks
  • Smart contract interactions with automatic ABI fetching
  • Applications prioritizing user-friendliness (ENS support, simplified address input)
  • Developers needing quick, API-key-free web search capabilities
  • Privacy-conscious users who prefer local search execution
  • AI application development with Claude Desktop or Claude Code
Not for
  • Applications requiring high-security transaction signing with key custody or hardware wallets
  • Production environments needing centralized business logic or dedicated API gateways
  • Enterprise applications requiring high-scale, reliable search APIs
  • Users needing advanced search features like custom ranking or filters
  • Accessing sites blocked by TLS fingerprinting without installing the optional browser backend
Required permissions
  • Read blockchain data (balances, transactions, blocks)
  • Sign transactions and transfer tokens using configured private key or mnemonic
  • Access external block explorer APIs (requires Etherscan API key)
  • Outbound network access to DuckDuckGo and other websites
  • Reads environment variables for SafeSearch, region, and CA certificates
  • Optionally reads a CA certificate file (for TLS-intercepting proxies)
Risks and side effects
  • Private key leakage can lead to loss of funds; must be kept confidential
  • Transactions are irreversible once on-chain; exercise caution with write operations
  • Automatic ABI fetching depends on third-party services; may fail
  • Search endpoints may occasionally return empty results or errors, especially when blocked
  • Content fetching may be subject to SSRF protection, blocking private or loopback addresses by default
  • Misuse could lead to rate limiting or IP blocking
