Getting Started with Okto SDK

The world of Web3 is revolutionizing how we interact with the internet, bringing decentralized applications (dApps) that empower users like never before. However, despite its potential, developing on Web3 can be challenging because of the complexities of blockchain technology and unfamiliar protocols. But what if you could build Web3 applications as easily as traditional web apps?

Enter the Okto SDK — your gateway to easy Web3 development. Designed to abstract blockchain complexities, the Okto SDK enables you to create powerful and user-friendly applications without getting bogged down by technical challenges. In this blog, we’ll guide you through everything you need to know to get started with the Okto SDK and confidently begin your Web3 journey.

What is Okto SDK?

Before diving into the setup, let’s discuss what makes the Okto SDK a game-changer for developers.

The Okto SDK is a comprehensive toolkit that simplifies the development of Web3 applications. It provides a chain abstraction layer that allows you to build consumer apps in a way that feels familiar. By managing the complex blockchain interactions behind the scenes, the SDK lets you focus on delivering the seamless user experiences expected from modern web applications.

The Okto SDK makes blockchain development much easier by providing features like single function calls for any blockchain action, a unified portfolio across different ecosystems, and abstraction of chain, account, and gas details. This means you can focus on creating easy-to-use interfaces and fun features without needing to worry about the technical blockchain details. The SDK’s plug-and-play nature also makes it highly customizable, allowing you to adapt it to your specific project needs.

Ways to Build on Okto

Recognizing that developers have different preferences and project requirements, Okto offers several ways to integrate its powerful features into your applications.

1. Okto React SDK: Ideal for building web applications using React.
2. Okto React Native SDK: Perfect for creating mobile apps with React Native.
3. Okto Flutter SDK: Designed for mobile developers working with Flutter/Dart.
4. Unity SDK: Ideal for game developers using Unity for web/mobile/desktop/playstation games.
5. Direct API Integration: For those who prefer to interact directly via APIs or working on any other platform not supported by the SDKs.

No matter your platform of choice, Okto ensures a smooth development experience across various technologies.

Prerequisites

Before you start building your app using Okto, there are a couple of things you need to set up.

1. Get Your Okto App Secret

The first step is to sign up on the Okto Dashboard to obtain your Okto App Secret. This key is crucial for authenticating your API requests. Make sure to keep it secure and never expose it publicly or include it in client-side code.

1. Navigate to the Dashboard Login Page: Go to Okto Dashboard.
2. Enter Your Email Address: Input your preferred email to log in.
3. Verify Your Email: Enter the OTP you received in your inbox.
4. Access Your Dashboard: Once verified, you’ll be logged into your new dashboard account.
5. Get Your App Secret: Navigate to the “API Keys” section and click on “Get App Secret.”

2. Authentication Methods

User authentication is a vital component of any application. The Okto SDK supports multiple authentication methods to onboard users seamlessly.

Currently, Okto offers the following authentication options:

1. Google OAuth: To authenticate users via Google, you’ll need to set up a Google Console Project.

• Follow our Google OAuth2 Setup Guide to create a project in Google Cloud Console.
• Once configured, you’ll receive a Google Client ID that will be used in your application for secure authentication.

2. Email OTP: Okto allows users to log in using their email addresses with a secure One-Time Password (OTP). The SDK manages the process of generating, sending, and verifying OTPs, ensuring a smooth user experience.

3. Phone OTP: With phone OTP authentication, users can log in using their phone numbers with a secure One-Time Password (OTP). The SDK securely handles OTP generation, sending, and verification.

Okto also plans to support other methods like Apple ID, Telegram, and Farcaster in the future.

3. Enable Chains and Tokens

It is compulsory to enable chains and tokens on the Okto Dashboard. This step is necessary to ensure your application can interact with supported blockchain networks.

4. Optional: Enable Sponsorship

You may also choose to enable sponsorship, which is a feature that allows you to cover transaction fees (gas fees) for your users. This creates a smoother user experience by removing the need for users to hold native tokens for transaction fees.

Sponsorship integrates with Okto’s wallet infrastructure to automatically cover gas fees for transactions on supported chains. When a user initiates a transaction, the sponsorship system pays the required gas fee, allowing the transaction to proceed even if the user doesn’t have the native token for gas.

Available SDKs

Now that you’ve completed the prerequisites, let’s take a closer look at the SDKs Okto offers. Each SDK is designed to integrate seamlessly with your preferred development platform.
