Native + USDC + custom-token balances for any wallet on Base, Ethereum, or Solan
Native + USDC + custom-token balances for any wallet on Base, Ethereum, or Solana — with USD estimates — straight from public RPCs, no API key. Raw units as decimal strings plus formatted numbers; add up to 10 ERC-20 contracts via tokens=. 60s cache; an empty, never-used address is a real answer (zeros + no_activity_detected finding).
