Returns

  • Array - 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 (DATA, 32 Bytes), e.g. ["0x3454645634534..."].
    • For filters created with eth_newPendingTransactionFilter the return are transaction hashes (DATA, 32 Bytes), e.g. ["0x6345343454645..."].
    • For filters created with eth_newFilter logs are objects with following params:
      • removed: TAG - true when the log was removed, due to a chain reorganization. false if its a valid log.
      • logIndex: QUANTITY - integer of the log index position in the block. null when its pending log.
      • transactionIndex: QUANTITY - integer of the transactions index position log was created from. null when its pending log.
      • transactionHash: DATA, 32 Bytes - hash of the transactions this log was created from. null when its pending log.

      • address: DATA, 20 Bytes - address from which this log originated.
      • data: DATA - contains one or more 32 Bytes non-indexed arguments of the log.
      • topics: Array of DATA - Array of 0 to 4 32 Bytes DATA 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.)
