# IEventContext

For event handlers, the context typically includes details such as:

* ILog: The transaction log containing the event data.
* ITransaction: The associated transaction details (e.g., sender, recipient, value).
* IBlock: The block information (e.g., block number, timestamp).
* The raw event parameters emitted by the smart contract.

```typescript
import {
  IEventContext,
  IBind,
  Instance,
  ISecrets,
} from "@blockflow-labs/utils";

/**
 * @dev Event::Transfer(address from, address to, uint256 value)
 * @param context trigger object with contains {event: {from ,to ,value }, transaction, block, log}
 * @param bind init function for database wrapper methods
 */
export const TransferHandler = async (
  context: IEventContext,
  bind: IBind,
  secrets: ISecrets,
) => {
  // Implement your event handler logic for Transfer here

  const { event, transaction, block, log } = context;
  const { from, to, value } = event;
};
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.blockflow.network/cli/glossary/ieventcontext.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
