Parameters

• hash — the hash of the block
• quantity — the integer identifying the transaction index position within the block, encoded as hexadecimal

Response

• object — a transaction response object, or null if no transaction is found:
  • blockHash — the block hash. Identifies the block in which the transaction was included. This field is null for transactions that have not yet been included in a block.
  • blockNumber — the number of the block in which the transaction was included. This field is null for transactions that have not yet been included in a block.
  • from — the address of the sender who initiated the transaction.
  • gas — the units of gas included in the transaction by the sender.
  • gasPrice — the price of gas in Wei included in the transaction by the sender.
  • maxFeePerGas — the maximum amount the transaction's sender is willing to pay per unit of gas for the transaction to be executed.
  • maxPriorityFeePerGas — the maximum priority fee the transaction sender is willing to pay per unit of gas.
  • hash — the hash that uniquely identifies the transaction.
  • input — the optional input data sent with the transaction, usually used to interact with smart contracts.
  • nonce — a counter identifying the transaction's number sent by the sender's wallet. It essentially identifies how many transactions an account has made. Used to ensure each transaction is executed only once.
  • to — the recipient's address of the transaction if it was a transaction to an address. For contract creation transactions, this field is null.
  • transactionIndex — the index of the transaction within the block. It is null for transactions that have not yet been included in a block.
  • value — the value of the native token transferred along with the transaction, in Wei.
  • type — the type of the transaction. 0 indicates a regular transfer; 2 indicates a contract creation or smart contract function call.
  • accessList — a list of authorized addresses and storage keys with which the transaction plans to interact.
  • v — the recovery parameter in the Ethereum Signature Algorithm (ECDSA).
  • r — the first component of the signature in the Ethereum Signature Algorithm (ECDSA).
  • s — the second component of the signature in the Ethereum Signature Algorithm (ECDSA).
