# getWrapperExpiry

Gets wrapper expiry for wrapped names, expiries, and fuses.

## Import

```ts
import { getWrapperExpiry } from "@ensforge/core";
```

## Usage

:::code-group
```ts [index.ts]
import { getWrapperExpiry } from "@ensforge/core";
import { config } from "./config";

const result = await getWrapperExpiry(config, {
  name: "example.eth",
});
```

```ts [config.ts]
// [!include ~/snippets/core/config.ts]
```
:::

## Parameters

```ts
import type { WrapperReadParameters } from "@ensforge/core";
```

### name

`string`

ENS name to operate on. ensforge normalizes it before hashing or contract interaction.

### blockNumber

`bigint | undefined`

Block number to read from. Cannot be combined with `blockTag`.

### blockTag

`"latest" | "earliest" | "pending" | "safe" | "finalized" | undefined`

Named block state to read from. Cannot be combined with `blockNumber`.

## Return Type

```ts
import type { GetWrapperExpiryResult } from "@ensforge/core";
```

| Property    | Type                                          | Description                                            |
| ----------- | --------------------------------------------- | ------------------------------------------------------ |
| `protocol`  | `"v1" \| "v2"`                                | ENS protocol route used for the result.                |
| `supported` | `true \| false`                               | Whether the selected protocol supports this operation. |
| `wrapped`   | `boolean \| undefined`                        | Whether the name is held by the ENS Name Wrapper.      |
| `expiry`    | `bigint \| null \| undefined`                 | The expiry value returned by the operation.            |
| `reason`    | `"WRAPPER_EXPIRY_NOT_SUPPORTED" \| undefined` | The reason value returned by the operation.            |

## Effect

Use `.effect` when composing the action in an Effect program. The success and error channels remain
fully typed.

```ts
import { Effect } from "effect";

const program = getWrapperExpiry.effect(config, parameters);

type Success = Effect.Effect.Success<typeof program>;
type Failure = Effect.Effect.Error<typeof program>;

const result = await Effect.runPromise(program);
```

## Request

Use `.request` to describe the read without executing it, then include it in a typed
[read batch](/core/guides/batching).

```ts
const request = getWrapperExpiry.request(parameters);
```

## Error

```ts
import type { GetWrapperExpiryError } from "@ensforge/core";
```

The Promise API rejects with the same typed failures exposed by the Effect error channel. Errors
have a stable `_tag`, `code`, and `message`; boundary errors retain their original `cause`.

See [Error Handling](/core/guides/error-handling).
