LogParams

Properties

Property	Modifier	Type	Description
`address`	`readonly`	`string`	The address of the contract that emitted this log.
`blockHash`	`readonly`	`string`	The block hash of the block this log occurred in. Use the Log.getBlock to get the Block.
`blockNumber`	`readonly`	`number`	The block number of the block this log occurred in. It is preferred to use the Block.hash \| Block.hash when fetching the related Block, since in the case of an orphaned block, the block at that height may have changed.
`data`	`readonly`	`string`	The data included in this log when it was emitted.
`index`	`readonly`	`number`	The index within the block this log occurred at. This is generally not useful to developers, but can be used with the various roots to proof inclusion within a block.
`provider`	`readonly`	`Provider`	The provider connected to the log used to fetch additional details if necessary.
`removed`	`readonly`	`boolean`	If the Log represents a block that was removed due to an orphaned block, this will be true. This can only happen within an orphan event listener.
`topics`	`readonly`	readonly `string`[]	The indexed topics included in this log when it was emitted. All topics are included in the bloom filters, so they can be efficiently filtered using the Provider.getLogs method.
`transactionHash`	`readonly`	`string`	The transaction hash of the transaction this log occurred in. Use the Log.getTransaction to get the **TransactionResponse.
`transactionIndex`	`readonly`	`number`	The index within the transaction of this log.
