Solana has now launched a mobile-first development toolkit, including wallet adapters, transaction assistants, and templates.

Developers can use React Native to develop applications for both iOS and Android simultaneously.

Wallet connections based on deep linking (such as Phantom and Backpack) do not require building a backend.

Applications can directly query balances, NFTs, and support operations like exchanges or minting through Solana RPC.

Open-source tools like the Solana Mobile App Kit support zero-infrastructure deployment.

In the past, developing decentralized applications (DApps), especially for mobile, was cumbersome: it required setting up backend services, integrating multiple wallets, and adapting to different platforms. By 2025, all of this has been transformed.

With the release of the Solana Mobile App Kit, React Native development suite, and SEND Kit ecosystem, developers can now create Solana-based mobile DApps for iOS and Android in just 15 minutes without any backend development.

This guide will walk you through the steps to build a mobile DApp that can connect to Solana wallets, display assets, support basic DeFi operations (like token exchanges), and run entirely on-chain. Let’s dive into how it works and why this approach is becoming the new standard for Web3 mobile applications.

The number of Solana developers has surged, particularly in the consumer and DeFi application sectors. With the increase in mobile users, developers increasingly need convenient wallet connections, UI rendering, and on-chain interaction solutions without relying on complex backends.

Solana's mobile development tools are natively compatible with mainstream mobile platforms, requiring no self-built infrastructure and are ready to use. Developers can focus on functionality, user experience, and agile deployment. The integration of Solana Mobile App Kit and React Native brings:

• Pre-configured wallet adapters and deep link support.
• Mobile components for NFTs, balances, and tokens.
• A single codebase that supports both iOS and Android.

Whether you want to create an NFT marketplace, a DeFi asset tracker, or a meme token issuance tool, Solana's mobile technology solutions offer both efficiency and flexibility.

The currently recommended tech stack facilitates rapid development and deployment:

• React Native: A cross-platform application development framework.
• Solana Mobile App Kit: A mobile SDK that integrates Solana's native features.
• Wallet Adapter (React Native): Enables plug-and-play wallet connections.
• SEND Kit: Provides application templates for NFTs, tokens, and DeFi scenarios.
• @solana/web3.js: Connects to Solana RPC endpoints to handle on-chain transactions.
• Phantom/Backpack wallets: Wallet applications that support deep linking.

With the above tech stack, developers need not worry about infrastructure, backend databases, or user authentication; all aspects are handled by the wallet.

Did you know: The Solana App Kit, developed by the SEND ecosystem, offers a one-click mobile application scaffold with built-in deep wallet integration, exchanges, NFT minting, AI components, and integration with over 18 protocols, ready to use out of the box.

The specific steps are as follows:

First, initialize a new React Native application. You can quickly generate a fully functional mobile DApp using just one command with the Solana AppKit's CLI tool:

npx start-solana-app

This command will set up a cross-platform iOS and Android application pre-installed with Solana wallet support, RPC tools, and basic UI components.

There is no need to build a login system; simply use the React Native Wallet Adapter to integrate wallets like Phantom and Backpack through deep linking, allowing users to securely connect their wallets and sign transactions without backend involvement.

In addition to deep linking, Solana also provides a native Mobile Wallet Adapter (MWA) protocol and its accompanying React Native library (@solana-mobile/mobile-wallet-adapter-protocol-web3js) for direct communication with wallets.

Once connected, you can use @solana/web3.js to query user account information, including SOL balances, SPL tokens, and NFTs. These operations are all completed directly on the client side through Solana RPC nodes.

The Solana AppKit natively supports mainstream DeFi and NFT protocols like Jupiter, Metaplex, and Pump.fun. Users can complete token exchanges, NFT minting, or memecoin issuance through built-in modules, with all transactions submitted via wallet adapters.

Compile and test the application using the React Native toolchain (npx react-native run-ios or run-android). The Solana ecosystem's native development (SEND) suite also provides various modular application templates to facilitate rapid customization and deployment, such as:

These templates allow developers to focus on design and user experience, while the underlying blockchain logic is automatically handled by the system.

Developing decentralized applications without a backend not only saves time but also represents a fundamental shift in Web3 architecture. Traditional Web3 development relied on centralized services for key functions like authentication, token metadata, and session management, but now, with wallet adapters and Solana RPC, these processes can be fully completed on the frontend without backend support.

Let’s compare this modern architecture with traditional Web3 development methods:

The architectural transformation brings several advantages:

• Faster launch cycles: No need to develop, deploy, and maintain a backend; teams can release prototypes or official applications within days.
• Lower maintenance costs: No servers, eliminating concerns about infrastructure patching, monitoring, or scaling.
• Better user experience: Wallet login replaces complex registration processes, allowing users to connect with one click.
• Higher security: The risk of backend attacks is completely eliminated, with wallets like Phantom and Backpack ensuring that private keys and session data never touch centralized servers.
• True decentralization: Every interaction is completed directly on-chain, whether it's NFT minting, token exchanges, or balance queries, without any intermediaries.

This native mobile, backend-less development model is particularly suitable for DApps that demand high efficiency and low costs.

Did you know: By developing for mobile users, developers have the opportunity to reach over 6 billion mobile users worldwide, covering both iOS and Android, without maintaining multiple codebases or backend infrastructures.

Once your MVP is live, you can further expand functionality in the following ways:

• Integrate Solana Pay for offline or QR code payments.
• Add push notification features for transaction events.
• Support Face ID or other biometric security measures.
• Use open-source analytics tools to track on-chain user engagement.
• Expand support for more crypto wallets through modular configurations of the Wallet Adapter.
• Utilize the React Native library to add dark mode, offline access, or multilingual support.

Whether it's memecoins, NFT minting, or DeFi tools, mobile-first blockchain experiences are gradually becoming mainstream. If you are a developer or a startup founder focused on the Web3 space, now is the best time to drive mobile transformation.
