eth_getLogs (BSC)

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

Parameters

Object - The filter options:

• fromBlock: QUANTITY|TAG - (optional, default: "latest") Value:

• Integer block number

• "latest" for the last mined 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) 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.

• 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.
