Returns a single, verifiable snapshot of any EVM wallet: native balance, ERC-20 token balances, current block number, and recent activity count across the most popular chains (Ethereum, Base, Arbitrum, Polygon). Built for x402 agents that need on-chain facts without managing RPC keys or node infrastructure. Each call returns a deterministic JSON payload with a chain-specific block number at snapshot time so results can be independently verified against a public RPC or block explorer.
