Returns an array of all logs matching a given filter object. This method will use 80 Compute Units.

Parameters

  1. Object - The filter options:
  • fromBlock: QUANTITY|TAG - (optional, default: "latest") Integer block number, or "latest" for the last mined block, "safe" or "finalized" for the latest safe or finalized block, "pending" for the pending block, or "earliest" for the genesis block.
  • toBlock: QUANTITY|TAG - (optional, default: "latest") Integer block number, or "latest" for the last mined block, "safe" or "finalized" for the latest safe or finalized block, "pending" for the pending block, or "earliest" for the genesis block.
  • 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) Restricts the logs returned to the single block with the 32-byte hash blockHash (EIP-234). 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

See eth_getFilterChanges: Array - Array of log objects matching the filter, or an empty array if none match. Each log object has the following fields:
  • removed: Boolean - 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 declared the event with the anonymous specifier.)
