The blockchain landscape is evolving rapidly, and user experience (UX) has become a critical differentiator for Web3 applications. While Solana offers high-speed transactions and low fees, the traditional onboarding process—requiring external wallets, seed phrase management, and gas payments—remains a significant barrier for mainstream adoption.
To unlock mass user growth, developers must deliver frictionless, secure, and intuitive experiences that feel native to Web2 standards. By leveraging modern tools like Privy and Helius, it’s now possible to build seamless Solana applications with embedded wallets, gasless transactions, fiat onramps, and cross-chain liquidity bridging—all without compromising security or decentralization.
This guide explores how to create a next-generation user experience on Solana, drawing inspiration from successful platforms like Pump.fun, Jupiter, and Moonwalk.
Building Frictionless Onboarding for Solana Applications
Modern crypto users expect instant access, minimal steps, and zero technical overhead. Unfortunately, most Web3 apps still rely on external wallets like Phantom or Backpack, forcing users through complex setup flows involving seed phrases, browser extensions, and repeated transaction confirmations.
These barriers lead to high drop-off rates—especially among non-technical users. The solution lies in embedded wallet infrastructure that abstracts away blockchain complexity while maintaining self-custody.
With Privy’s SDK, developers can enable login via email, social accounts (Google, X), or SMS—automatically provisioning a self-custodial embedded wallet under the hood. This approach allows users to interact with Solana-based apps instantly, without ever seeing a wallet popup or managing private keys manually.
Meanwhile, Helius provides high-performance RPC infrastructure with sub-20ms latency, ensuring fast transaction finality and reliable connectivity across mobile and desktop environments.
Together, these technologies form a powerful stack for building consumer-grade Web3 experiences.
Why Seamless Onboarding Matters
Frictionless onboarding isn’t just about convenience—it directly impacts retention and growth. Applications using embedded wallets report over 40% monthly active user retention, particularly when targeting crypto newcomers.
Key pain points addressed by this model include:
- Eliminating seed phrase management
- Removing repeated transaction signing
- Hiding gas fees through sponsorship
- Supporting familiar login methods
The goal is simple: let users trade, stake, or earn rewards without needing to understand how blockchain works.
Real-World Examples of Seamless UX on Solana
Pump.fun – Instant Token Trading Experience
Pump.fun revolutionized meme token trading by combining one-click swaps with gasless transactions powered by embedded wallets. Originally designed for power traders, its advanced interface proved so effective that it was rolled out to all users.
Now, anyone can launch a token and begin trading within seconds—entirely from a mobile device. Behind the scenes, Privy manages wallet creation and authentication via email or social logins, while gas fees are sponsored server-side. Users trade millions in volume without ever leaving the app or interacting with traditional wallet interfaces.
Jupiter – Unified DEX Aggregation
Jupiter leverages Privy’s infrastructure to power its Quick Account feature. Whether users log in via Phantom, Solflare, or simply with an email or X account, they all interact through Privy’s embedded wallet layer.
This enables instant swaps without signature prompts, delivering a smooth, uninterrupted trading experience. When users are ready to take full control, they can export their keys to an external wallet—ensuring no vendor lock-in.
Moonwalk – Web2-Like Fitness App UX
Moonwalk, a walk-to-earn mobile app, onboards users just like any mainstream fitness app—using email, social login, or phone number. Privy automatically creates a functional Solana wallet in the background.
Users earn tokens as they walk, completely unaware they’re interacting with blockchain technology. There’s no need to copy addresses, manage wallets, or pay gas—everything happens seamlessly behind the scenes.

Enhancing User Experience with Embedded Funding & Bridging
Creating a wallet is only the first step. To prevent user drop-off at funding stages, developers must also solve account top-ups and cross-chain liquidity access.
Embedded Fiat Onramps
Instead of redirecting users to third-party services, apps can embed fiat-to-crypto onramps directly into their UI. Privy supports integration with providers like MoonPay and Coinbase Pay, enabling users to buy SOL or USDC natively within the application.
This eliminates context switching and keeps users engaged in the core experience.
Native Cross-Chain Bridging
Many users hold assets on Ethereum, Base, or Polygon—but want to use them on Solana. With Privy’s native bridging capabilities, developers can allow users to bridge funds directly from EVM chains into their Solana wallets—without leaving the app.
No address copying. No manual bridging. Just seamless value transfer across chains.

Implementing Gasless Transactions Using Privy & Helius
Gas fees remain one of the biggest psychological barriers for new users. Fortunately, developers can sponsor these costs using a managed fee-payer wallet, creating a truly gasless experience.
Step 1: Set Up a Managed Wallet
Privy allows you to programmatically create a managed wallet that acts as a transaction sponsor. This wallet pays gas fees on behalf of users while preserving their control over assets.
Using the Privy Node.js SDK:
import { PrivyClient } from '@privy-io/server-sdk';
const privy = new PrivyClient({
apiKey: process.env.PRIVY_API_KEY
});
async function createFeePayerWallet() {
const { id, address } = await privy.walletApi.create({
chainType: 'solana',
idempotencyKey: 'unique_request_id'
});
console.log(`Fee payer wallet created: ${address}`);
return { id, address };
}Ensure this wallet is funded with SOL to cover transaction costs.
Step 2: Sponsor User Transactions
When a user signs a transaction via their embedded wallet, it's sent to your backend where the managed wallet adds its signature and broadcasts it to the network.
Client-Side (React + Privy SDK)
async function sendGaslessTransaction(instructions) {
const { wallets } = useSolanaWallets();
const embeddedWallet = wallets.find(w => w.walletClientType === 'privy');
const connection = new Connection('https://mainnet.helius-rpc.com/?api-key=YOUR_KEY');
const { blockhash } = await connection.getLatestBlockhash();
const feePayerAddress = 'YOUR_SERVER_WALLET_ADDRESS';
const message = new TransactionMessage({
payerKey: new PublicKey(feePayerAddress),
recentBlockhash: blockhash,
instructions
}).compileToV0Message();
const transaction = new VersionedTransaction(message);
const provider = await embeddedWallet.getProvider();
const serializedMsg = Buffer.from(transaction.message.serialize()).toString('base64');
const { signature } = await provider.request({
method: 'signMessage',
params: { message: serializedMsg }
});
transaction.addSignature(new PublicKey(embeddedWallet.address), Buffer.from(signature, 'base64'));
const serializedTx = Buffer.from(transaction.serialize()).toString('base64');
const res = await fetch('/api/sponsor-transaction', {
method: 'POST',
body: JSON.stringify({ transaction: serializedTx })
});
const { transactionHash } = await res.json();
return transactionHash;
}Server-Side (Next.js API Route)
export async function POST(request) {
const { transaction: serializedTx } = await request.json();
const txBuffer = Buffer.from(serializedTx, 'base64');
const transaction = VersionedTransaction.deserialize(txBuffer);
const serverWalletId = process.env.PRIVY_SERVER_WALLET_ID;
const { hash } = await privy.walletApi.solana.signAndSendTransaction({
walletId: serverWalletId,
caip2: 'solana:EtWTRABZaYq6iMfeYKouRu166VU2xqa1',
transaction: serializedTx,
rpcUrl: 'https://mainnet.helius-rpc.com/?api-key=YOUR_KEY'
});
return Response.json({ transactionHash: hash }, { status: 200 });
}By combining Privy’s secure key management with Helius’ optimized RPC layer, developers achieve reliable, low-latency gasless transactions.
