most commonly used by Solidity’s emit for announcing events.

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. |
