What problem does it solve?

This skill provides a reliable way to check native EVM balances and ERC20 token balances across multiple chains, helping you verify funds before transactions and monitor holdings.

Core Features & Use Cases

  • Cross-chain balance checks: Retrieve native ETH balances on Ethereum, Base, Polygon, and Arbitrum, including Sepolia testnets.
  • ERC20 token balances: Query common tokens (e.g., USDC) on supported chains.
  • Multi-chain aggregation & reliability: Uses built-in RPC endpoints to avoid flaky public nodes and can batch queries for efficiency.
  • Use Case: Before submitting a cross-chain transfer, check the sender’s ETH and token balances across involved chains to ensure sufficient funds.
