This guide explores how to build frictionless on-chain experiences for Solana using Privy and Helius. We'll cover embedded wallets, gasless transactions, fiat on-ramps, and native liquidity bridging to create apps with exceptional UX like Pump.fun, Jupiter, and Moonwalk.
The Technical Stack Bringing Millions to Solana
Developer Guide: Implement embedded wallets, gasless transactions, and smooth onboarding with Privy and Helius.
Most crypto applications rely on external wallets, forcing users to manage seed phrases, navigate redirects, and manually approve transactions. For mainstream users, this creates unnecessary friction that leads to drop-off.
The solution? Embedded wallets and sponsored transactions.
Key Benefits:
- Self-custody embedded wallets via email/social/SMS logins
- Gasless transactions through sponsored fee wallets
- Integrated fiat on-ramps (MoonPay, Coinbase Pay)
- Native liquidity bridging to Solana
- Mobile-first UX that feels like Web2
Crypto Onboarding in Action: DeFi and Consumer Apps
Seamless onboarding boosts retention. Apps using embedded wallets see 40%+ monthly user retention, especially among crypto newcomers.
Pump.fun – Token Launchpad
Combines embedded wallets with gasless transactions for one-click trading. Users launch tokens and trade millions without leaving the mobile app.
Jupiter – DEX Aggregator
Quick Account experience enables instant transactions via embedded wallet infrastructure. Users can later export keys to external wallets.
Moonwalk – Walk-to-Earn App
Web2-style onboarding with automatic embedded wallet creation. Users earn tokens without knowing they're on-chain.
Building Native Account Funding
Embedded On-Ramps
Direct fiat-to-crypto purchases within the app interface via MoonPay/Coinbase Pay integration.
Native Bridging
Bridge liquidity from EVM chains (Ethereum, Base, Polygon) when Solana wallets are underfunded.
Implementing Gasless Transactions
Step 1: Create a Managed Wallet
const { id, address } = await privy.walletApi.create({
chainType: 'solana'
});Step 2: Sponsor Transactions
Client-side:
const transaction = new VersionedTransaction(message);
const { signature } = await provider.signMessage();Server-side:
const { hash } = await privy.walletApi.solana.signAndSendTransaction({
walletId: serverWalletId,
transaction: serializedTx
});Flexible Tech Stack
Privy's modular SDK combined with Helius's high-performance RPC nodes provides the foundation for world-class Solana apps.
