Overview
ERC20 and native ETH wallet balance on Base or Ethereum mainnet, for a 0x address or an ENS name. decimals() and symbol() are read from the contract at request time rather than assumed, because assuming 18 reports a USDC balance a trillion times too large. ENS is resolved through two independent resolvers and the answer is used only when they agree, so a wrong address can never produce a confident balance for the wrong wallet. An unsupported chain is refused rather than silently answered from the wrong one.
