# Initialize Yield Position

> Create a yield position account before depositing YT

The `ixInitializeYieldPosition` method on the `Vault` class creates a transaction instruction that initializes a `YieldTokenPosition` PDA for a user. This must be called once per vault before the user can deposit YT.

## Usage

```typescript theme={null}
import { Vault, LOCAL_ENV } from "@exponent-labs/exponent-sdk";
import { Connection, PublicKey, 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 ix = vault.ixInitializeYieldPosition({
  owner: wallet.publicKey,
});

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

## Required Parameters

| Parameter | Type        | Description                   |
| --------- | ----------- | ----------------------------- |
| `owner`   | `PublicKey` | The owner's wallet public key |

## Returns

Returns a `TransactionInstruction` that creates the yield position PDA. The account is derived from the owner's public key and the vault address.

<Tip>
  This is a one-time operation per vault. After initialization, use [`YtPosition.loadByOwner`](/yield-stripping/typescript/read-functions/get-yield-position) to load the position and start depositing YT.
