# Monetize SDK

> Learn how to configure fees and monetize your LI.FI SDK integration.

<Note>
  For more details about how fees work, fee collection on different chains, and
  setting up fee wallets, see the [Monetizing the
  integration](/introduction/integrating-lifi/monetizing-integration) guide.
</Note>

When using the LI.FI SDK, you can monetize your integration by collecting fees from the transactions processed through your application. The SDK supports fee configuration in two ways: globally when creating the SDK client, or per-request through route options.

## Global fee configuration

The recommended approach is to configure fees globally when creating your SDK client using `createClient`. This ensures all requests use the same fee configuration automatically:

```typescript theme={"system"}
import { createClient } from '@lifi/sdk';

const client = createClient({
  integrator: 'Your dApp/company name',
  routeOptions: {
    fee: 0.01, // 1% fee applied to all requests
  },
  // other options...
});
```

With this configuration, all route requests, quotes, and contract calls will automatically include the specified fee without needing to add it to each individual request.

## Per-request fee configuration

Alternatively, you can configure fees on a per-request basis. This is useful when you need different fee rates for different types of transactions or users. The `fee` parameter can be added to the `options` object when requesting routes or quotes.

### Basic route request with fees

```typescript theme={"system"}
import { getRoutes } from '@lifi/sdk';

const routesRequest = {
  fromChainId: 42161, // Arbitrum
  toChainId: 10, // Optimism
  fromTokenAddress: '0xaf88d065e77c8cC2239327C5EDb3A432268e5831', // USDC on Arbitrum
  toTokenAddress: '0xDA10009cBd5D07dd0CeCc66161FC93D7c9000da1', // DAI on Optimism
  fromAmount: '10000000', // 10 USDC
  options: {
    integrator: 'Your dApp/company name',
    fee: 0.01, // 1% fee
  },
};

const result = await getRoutes(client, routesRequest);
const routes = result.routes;
```

### Quote request with fees

```typescript theme={"system"}
import { getQuote } from '@lifi/sdk';

const quoteRequest = {
  fromChain: 42161, // Arbitrum
  toChain: 10, // Optimism
  fromToken: '0xaf88d065e77c8cC2239327C5EDb3A432268e5831', // USDC on Arbitrum
  toToken: '0xDA10009cBd5D07dd0CeCc66161FC93D7c9000da1', // DAI on Optimism
  fromAmount: '10000000', // 10 USDC
  fromAddress: '0x552008c0f6870c2f77e5cC1d2eb9bdff03e30Ea0',
  integrator: 'Your dApp/company name',
  fee: 0.01, // 1% fee
};

const quote = await getQuote(client, quoteRequest);
```
