class human_protocol_sdk.transaction.transaction_utils.TransactionUtils

Bases: object

A utility class that provides additional transaction-related functionalities.

static get_transaction(chain_id, hash)

Returns the transaction for a given hash.

• Parameters:

  • chain_id (ChainId) – Network in which the transaction was executed
  • hash (str) – Hash of the transaction

• Return type: Optional[TransactionData]
• Returns: Transaction data

• Example:

  from human_protocol_sdk.constants import ChainId
  from human_protocol_sdk.transaction import TransactionUtils
  
  print(
      TransactionUtils.get_transaction(
          ChainId.POLYGON_AMOY,
          "0x1234567890123456789012345678901234567891"
      )
  )

static get_transactions(filter)

Get an array of transactions based on the specified filter parameters.

• Parameters: filter (TransactionFilter) – Object containing all the necessary parameters to filter
• Return type: List[TransactionData]
• Returns: List of transactions

• Example:

  from human_protocol_sdk.constants import ChainId
  from human_protocol_sdk.transaction import TransactionUtils, TransactionFilter
  
  print(
      TransactionUtils.get_transactions(
          TransactionFilter(
              chain_id=ChainId.POLYGON_AMOY,
              from_address="0x1234567890123456789012345678901234567890",

              start_date=datetime.datetime(2023, 5, 8),
              end_date=datetime.datetime(2023, 6, 8),
          )
      )
  )

exception human_protocol_sdk.transaction.transaction_utils.TransactionUtilsError

Bases: Exception

Raises when some error happens when getting data from subgraph.
