# useDelegationStatus

Query hook that checks whether a decryption delegation is active between a delegator and delegate for a specific contract. Returns both the active status and the raw expiry timestamp.

## Import

```ts
import { useDelegationStatus } from "@zama-fhe/react-sdk";
```

## Usage

{% tabs %}
{% tab title="component.tsx" %}

```tsx
import { useDelegationStatus } from "@zama-fhe/react-sdk";

function DelegationBadge({
  contractAddress,
  delegatorAddress,
  delegateAddress,
}: {
  contractAddress: `0x${string}`;
  delegatorAddress: `0x${string}`;
  delegateAddress: `0x${string}`;
}) {
  const { data, isLoading } = useDelegationStatus({
    contractAddress,
    delegatorAddress,
    delegateAddress,
  });

  if (isLoading) return <span>Checking...</span>;
  if (!data?.isActive) return <span>Not delegated</span>;

  const expiry = data.expiryTimestamp;
  const label =
    expiry === BigInt("18446744073709551615")
      ? "Permanent"
      : `Expires ${new Date(Number(expiry) * 1000).toLocaleDateString()}`;

  return <span>Delegated ({label})</span>;
}
```

{% endtab %}
{% endtabs %}

## Parameters

```ts
import { type UseDelegationStatusConfig } from "@zama-fhe/react-sdk";
```

### contractAddress

`Address`

Address of the confidential contract.

### delegatorAddress

`Address | undefined`

The address that granted the delegation. The query is disabled until this is provided.

### delegateAddress

`Address | undefined`

The address that received delegation rights. The query is disabled until this is provided.

```ts
const { data } = useDelegationStatus({
  contractAddress: "0xToken",
  delegatorAddress: "0xDelegator",
  delegateAddress: "0xDelegate",
});
```

## Return Type

```ts
import { type DelegationStatusData } from "@zama-fhe/sdk/query";
```

`data` resolves to:

| Property          | Type      | Description                                                               |
| ----------------- | --------- | ------------------------------------------------------------------------- |
| `isActive`        | `boolean` | `true` if delegation exists and hasn't expired.                           |
| `expiryTimestamp` | `bigint`  | `0n` = no delegation, `2^64 - 1` = permanent, otherwise UTC Unix seconds. |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.zama.org/protocol/sdk/api-references/react/usedelegationstatus.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.
