eth_getBlockByHash

Returns information about a block by hash.

Parameters

Name
Type
Description

BlockHash

HexString<Hash>

Hash of the selected block.

ShowTransactionDetails

Boolean

If true returns the full transaction objects, otherwise the hashes of the transactions.

Return Type

Block | null - The block data or null if not found.

Block

type Block = {
  number: HexString<Number> | null; // Block number or null if block is pending.
  hash: HexString<Hash> | null; // Block hash or null if block is pending.
  parentHash: HexString<Hash>; // Hash of the parent block.
  nonce: HexString<Hash> | null; // Hash of the proof-of-work or null if block is pending.

  sha3Uncles: HexString<Hash>; // SHA3 hash of the uncles data in the block.
  logsBloom: HexString<FilterBloom> | null; // Bloom filter of the logs in the block or null if block is pending.
  transactionsRoot: HexString<Hash>; // Root hash of the transaction trie of the block.
  stateRoot: HexString<Hash>; // Root hash of the final state trie of the block.
  receiptsRoot: HexString<Hash>; // Root hash of the receipts trie of the block.

  miner: Address; // Miner's address for rewards.
  difficulty: HexString<Number>; // Difficulty for this block.
  totalDifficulty: HexString<Number>; // Total difficulty for the chain until this block.

  extraData: HexString; // 32-byte long space to preserve for the ethernity :]
  gasLimit: HexString<Number>; // Maximum gas allowed for this block.
  gasUsed: HexString<Number>; // Total gas used for all transactions in this block.

  size: HexString<Number>; // Size of this block in bytes.
  timestamp: HexString<Number>; // The unix timestamp for when the block was collated.

  transactions: Transaction[] | HexString<Hash>[]; // Array of transaction objects or transaction hashes.

  uncles: HexString<Hash>[]; // Array of uncle hashes.
};

Transaction

type Transaction = {
  hash: HexString<Hash>; // Hash of the transaction.
  from: Address; // Address of the sender.
  to: Address | null; // Address of the receiver or null for contract creations.
  value: HexString<Number>; // Value sent in WEI.

  blockHash: HexString<Hash> | null; // Block hash of transaction or null if transaction is pending.
  blockNumber: HexString<Number> | null; // Block number of transaction or null if transaction is pending.
  nonce: HexString<Number>; // Number of transactions made by the sender before.

  gas: HexString<Number>; // Gas units provider by the sender.
  gasPrice: HexString<Number>; // Gas price provider by the sender in WEI.
  maxFeePerGas?: HexString<Number>; // Maximum fee in WEI per gas unit. EIP-1559.
  maxPriorityFeePerGas?: HexString<Number>; // Maximum fee in WEI per gas unit above the base fee. EIP-1559.

  input: HexString; // Data sent with the transaction.

  r: HexString; // ECDSA signature r.
  s: HexString; // ECDSA signature s.
  v: HexString; // ECDSA recovery ID.

  transactionIndex: HexString<Number> | null; // Transaction index in block or null if transaction is pending.
  type: HexString<Number>; // Transaction type
