# Implementation Paths

There are two ways to integrate Gelato Turbo Relayer into your application. Choose the approach that best fits your development workflow and requirements.

## Gelato Gasless SDK

The `@gelatocloud/gasless` SDK provides the simplest integration path for gasless transactions using Gelato Relay.

* Simple transaction relay without smart account or implementing EIP-7702 Smart Account
* Built-in support for sponsored transactions via Gas Tank
* Automatic gas estimation and transaction polling

```bash theme={null}
npm install @gelatocloud/gasless
```

## Relay API Endpoints

For maximum flexibility or non-JavaScript environments, interact directly with Gelato's Relay API endpoints.

* Language-agnostic integration via standard HTTP requests
* Full control over request/response handling
* Supports sponsored transactions via Gas Tank
* Useful for backend services, mobile apps, or custom implementations
* Requires manual transaction construction

## Code Examples

Throughout this section, code examples are presented in three tabs:

* **Gasless SDK** - Using `@gelatocloud/gasless` for simple relay transactions
* **Gasless SDK with 7702 Smart Account** - Using `@gelatocloud/gasless` with EIP-7702 smart account features
* **API Endpoints** - Direct HTTP requests to Gelato's Relay API
