eth_getFilterLogs

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

REQUEST PARAMS

• FILTER OBJECT

  • fromBlock[optional, default: "latest"] hexadecimal block number, or "latest" for the last mined block. The "pending" option is not currently supported.

  • toBlock[optional, default: "latest"] hexadecimal block number, or "latest" for the last mined block.

  • 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] With the addition of EIP-234, blockHash 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 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.

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

• transactionIndex: hexadecimal 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.)
