eth_getLogs

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

Parameters:

  1. Object - The filter options:

  • fromBlock: QUANTITY|TAG - (optional, default: "latest") Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.

  • toBlock: QUANTITY|TAG - (optional, default: "latest") Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.

  • address: DATA|Array, 20 Bytes - (optional) Contract address or a list of addresses from which logs should originate.

  • topics: Array of DATA, - (optional) Array of 32 Bytes DATA topics. Topics are order-dependent. Each topic can also be an array of DATA with "or" options.

  • blockhash: 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.

params: [
  {
    topics: [
      "0x000000000000000000000000a94f5374fce5edbc8e2a8697c15331677e6ebf0b",
    ],
  },
]

Returns:

array - An array of one of the following, depending on the filter type, or empty if there were no changes since the last poll:

  • eth_newBlockFilter:

    blockHash - The 32 byte hash of a block that meets your filter requirements

  • eth_newPendingTransactionFilter:

    transactionHash - The 32 byte hash of a transaction that meets your filter requirements

  • eth_newFilter:

    address - An address from which this log originated

    topics - An array of zero to four 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 declare the event with the anonymous specifier

    data - It contains one or more 32 Bytes non-indexed arguments of the log

    blockNumber - The block number where this log was in. null when its a pending log

    transactionHash - The hash of the transactions this log was created from. null when its a pending log

    transactionIndex - The integer of the transaction's index position that the log was created from. null when it's a pending log

    blockHash - The hash of the block where this log was in. null when its a pending log

    logIndex - The integer of the log index position in the block. null when it's a pending log

    removed - It is true when the log was removed due to a chain reorganization, and false if it's a valid log
