## Functions

### Borrowing Assets

To borrow assets using the SDK, use the `borrow` function from the `action` module:

<pre class="language-typescript"><code class="lang-typescript"><strong>export const borrow = async (
</strong><strong>        amount: BigInt, 
</strong><strong>        assets: Array&#x3C;Nft>, 
</strong><strong>        signature: Signature, 
</strong><strong>        options?: ClientOptions
</strong><strong>    )
</strong></code></pre>

```typescript
const result = await borrow(amount, assets[], signature, options?);
```

### Repaying Loans

To repay a borrowed loan, use the `repay` function from the `action` module:

```typescript
export const repay = async (
        amount: BigInt, 
        signature: Signature, 
        options?: ClientOptions
    )
```

```typescript
const result = await repay(amount, signature, options?);
```

***

Refer to the Action Module documentation for more details on the `borrow` and `repay` functions.
