eth_getLogs - Linea

Returns an array of all logs matching a given filter object. For more information about eth_getLogs check out our Deep Dive into eth_getLogs page.

Parameters

Object - The filter options:

  • fromBlock: QUANTITY|TAG - (optional, default: "latest") Value:
    • Integer block number
    • "latest" for the last mined block
    • "pending", "earliest" for not yet mined transactions.
  • toBlock: QUANTITY|TAG - (optional, default: "latest") Value:
    • Integer block number
    • "latest" for the last mined block
    • "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.
    • Check out more details on how to format topics in eth_newFilter.
  • blockHash: DATA, 32 Bytes - (optional) With the addition of EIP-234 (Geth >= v1.8.13 or Parity >= v2.1.0), blockHash is 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

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.
    • blockHash: DATA, 32 Bytes - Hash of the block where this log was in. Null when its pending. Null when its pending log.
    • blockNumber: QUANTITY - The block number where this log was in. Null when its pending. 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 declare the event with the anonymous specifier.
