REQUEST PARAMS

  • FILTER OBJECT

    • address [optional] - a string representing the address (20 bytes) to check for balance

    • fromBlock [optional, default is "latest"] - an integer block number, or the string "latest", "earliest" or "pending"

    • toBlock [optional, default is "latest"] - an integer block number, or the string "latest", "earliest" or "pending"

    • topics[optional] - Array of 32 Bytes DATA topics. Topics are order-dependent.

    • blockhash:[optional, **_future**]_ With the addition of EIP-234, blockHash will be a new filter option which restricts the logs returned to the single block with the 32-byte hash blockHash. Using blockHash is equivalent to fromBlock = toBlock = the block number with hash blockHash. If blockHash is present in in the filter criteria, then neither fromBlock nor toBlock are allowed.

RESULT FIELDS

  • LOG OBJECTS - An array of log objects, or an empty array if nothing has changed since last poll.

    • For filters created with eth_newBlockFilter the return are block hashes of 32 Bytes), e.g. ["0x3454645634534..."]

    • For filters created with eth_newPendingTransactionFilter the return are transaction hashes of 32 Bytes), e.g. ["0x6345343454645..."].

    • For filters created with eth_newFilter logs are objects with following params:

      • removed: true when the log was removed, due to a chain reorganization. false if its a valid log.

      • logIndex: integer of the log index position in the block. null when its pending log.

      • transactionIndex: integer of the transactions index position log was created from. null when its pending log.

      • transactionHash: 32 Bytes - hash of the transactions this log was created from. null when its pending log.

      • blockHash: 32 Bytes - hash of the block where this log was in. null when its pending. null when its pending log.

      • blockNumber: the block number where this log was in. null when its pending. null when its pending log.

      • address: 20 Bytes - address from which this log originated.

      • data: contains one or more 32 Bytes non-indexed arguments of the log.

      • topics: Array of 0 to 4 32 Bytes of indexed log arguments. (In solidity: The first topic is the hash of the signature of the event (e.g. Deposit(address,bytes32,uint256)), except you declared the event with the anonymous specifier.)
