Native balance, next nonce, and whether an address holds contract code. Pass token to read an ERC-20 balance in the same call.
Live gas price on Ethereum, Base, Arbitrum, Optimism or Polygon, in gwei plus the cost of a plain transfer. Compare several chains in one call.
ERC-20 name, symbol, decimals and total supply read from the contract itself, and confirmation the address has code on that chain.
Whether a transaction succeeded, failed or is pending, with block, sender, recipient, value, gas used and the fee actually paid.
