eth_getLogs​

Returns an array of all logs matching a given filter object.

Parameters​

  • id (integer; required): a request ID (example: 1).

  • jsonrpc (string; required): a JSON RPC spec used (example: 2.0).

  • method (string; required): a method used for the request.

  • params (array; required):

    1. object: the filter options:

      • fromBlock (string; quantity|tag; optional; default: "latest"): either the block number or one of the following block tags:

        • latest: for the last mined block.
        • earliest: for the lowest numbered block available on the client.
        • pending: for not yet mined transactions.

      • toBlock (string; quantity|tag; optional; default: "latest"): either the block number or one of the following block tags:

        • latest: for the last mined block.
        • earliest: for the lowest numbered block available on the client.
        • pending: for not yet mined transactions.

      • address (array of strings; data, 20 bytes; optional): a contract address or a list of addresses from which logs should originate.

      • topics (array of strings; data; optional): an array of 32 bytes data topics. Topics are order-dependent. Each topic can also be an array of data with "or" options.

      • blockhash (string; data, 32 bytes; 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 the filter criteria, then neither fromBlock nor toBlock are allowed.

Returns​

  • removed (string; tag): true when the log was removed, due to a chain reorganization; false if it's a valid log.
  • logIndex (string; quantity): the log index position in the block; null when it's a pending log.
  • transactionIndex (string; quantity): the transactions index position log was created from; null when it's a pending log.
  • transactionHash (string; data, 32 bytes): a hash of the transactions this log was created from; null when it's a pending log.
  • blockHash (string; data, 32 bytes): a hash of the block containing the log; null when it's pending; null when it's a pending log.
  • blockNumber (string; quantity): the number of the block containing the log; null when it's pending; null when it's a pending log.
  • address (string; data, 20 bytes): an address from which this log originated.
  • data (string; data): contains one or more 32 bytes non-indexed arguments of the log.
  • topics (array of strings; data): an 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.)
