# Deposit YT

> Deposit YT tokens into a yield position to start accruing interest

The `ixDepositYt` method on the `YtPosition` class creates a transaction instruction that deposits YT tokens into the yield position. Once deposited, the position begins accruing interest and emissions.

## 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);

const ix = ytPosition.ixDepositYt({
  amount: 1_000_000n,
});

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