🆕 A Base transaction by hash, unedited: from, to, value in wei and ETH, nonce, gas, fee caps, type, and the 4-byte method selector with the calldata size. Flags a contract creation (null to) and a still-pending transaction (null block) rather than leaving you to infer either. Unknown hashes answer found:false, not an error.
