# Collect Interest

> Collect staged interest from a yield position

The `ixCollectInterest` method on the `YtPosition` class creates a transaction instruction that collects staged interest (paid in SY) from the yield position.

## 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 staged interest
const ix = ytPosition.ixCollectInterest({
  signer: wallet.publicKey,
});

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

To collect a specific amount:

```typescript theme={null}
const ix = ytPosition.ixCollectInterest({
  signer: wallet.publicKey,
  amount: 500_000n,
});
```

## Required Parameters

| Parameter | Type        | Description                 |
| --------- | ----------- | --------------------------- |
| `signer`  | `PublicKey` | The position owner (signer) |

## Optional Parameters

| Parameter | Type        | Description                                            |
| --------- | ----------- | ------------------------------------------------------ |
| `syDst`   | `PublicKey` | Destination SY token account. Defaults to signer's ATA |
| `amount`  | `bigint`    | Specific amount to collect. Defaults to all available  |

## Returns

Returns a `TransactionInstruction` that transfers staged SY interest to the owner.

<Note>
  You must [stage yield](/yield-stripping/typescript/yt-instructions/ix-stage-yield) before collecting. Staging and collecting can be combined in the same transaction.
