eth_getFilterLogs

Returns an array of all logs matching filter with given id.

REQUEST PARAMS

  • FILTER OBJECT
  • fromBlock[optional, default: "latest"] Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.
  • toBlock[optional, default: "latest"] Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.
  • address: [optional] (20 Bytes) Contract address or a list of addresses from which logs should originate.
  • topics: [optional] Array of 32 Bytes DATA topics. Topics are order-dependent. Each topic can also be an array of DATA with "or" options.
  • 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.

RESPONSE

RESULT FIELDS

  • LOG OBJECT 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 (32 Bytes), e.g. ["0x3454645634534..."].
  • For filters created with eth_newPendingTransactionFilter the return are transaction hashes (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: DATA - contains the 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.)
