# Collect Emission

> Collect emission rewards from a yield position

The `ixCollectEmission` method on the `YtPosition` class creates a transaction instruction that collects a specific emission reward from the yield position. Emissions are auxiliary reward tokens (e.g., governance tokens) distributed to YT depositors.

## Usage

```typescript theme={null}
import { Vault, YtPosition, LOCAL_ENV } from "@exponent-labs/exponent-sdk";
import { Connection, Transaction, sendAndConfirmTransaction } from "@solana/web3.js";

const connection = new Connection("https://api.mainnet-beta.solana.com");
const vault = await Vault.load(LOCAL_ENV, connection, vaultAddress);
const ytPosition = await YtPosition.loadByOwner(LOCAL_ENV, connection, wallet.publicKey, vault);

// Collect all of emission at index 0
const ix = ytPosition.ixCollectEmission({
  owner: wallet.publicKey,
  emissionIndex: 0,
});

const tx = new Transaction().add(ix);
const signature = await sendAndConfirmTransaction(connection, tx, [wallet]);
```

To collect a specific amount:

```typescript theme={null}
const ix = ytPosition.ixCollectEmission({
  owner: wallet.publicKey,
  emissionIndex: 0,
  amount: 1_000_000n,
});
```

## Required Parameters

| Parameter       | Type        | Description                                |
| --------------- | ----------- | ------------------------------------------ |
| `owner`         | `PublicKey` | The position owner's wallet public key     |
| `emissionIndex` | `number`    | Index of the emission to collect (0-based) |

## Optional Parameters

| Parameter     | Type        | Description                                                 |
| ------------- | ----------- | ----------------------------------------------------------- |
| `emissionDst` | `PublicKey` | Destination emission token account. Defaults to owner's ATA |
| `amount`      | `bigint`    | Specific amount to collect. Defaults to all available       |

## Returns

Returns a `TransactionInstruction` that transfers accrued emission rewards to the owner.

<Tip>
  Use `ytPosition.getClaimableEmissions()` to check available emissions and their amounts before collecting.
