# IFunctionContext

For function handlers, the input object may contain:

* ITransaction: The associated transaction details (e.g., sender, recipient, value).
* IBlock: The block information (e.g., block number, timestamp).
* The function parameters passed during the contract call

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

/**
 * @dev Function::approve(address _spender, uint256 _value)
 * @param context trigger object with contains {functionParams: {_spender ,_value }, transaction, block}
 * @param bind init function for database wrapper methods
 */
export const approveHandler = async (
  context: IFunctionContext,
  bind: IBind,
  secrets: ISecrets,
) => {
  // Implement your function handler logic for approve here

  const { functionParams, transaction, block } = context;
  const { _spender, _value } = functionParams;
};
```
