At Privy, we build alongside our customers. Every feature and every optimization is driven by a direct developer need, built in tandem with the best products revolutionizing their space. This means much of what you see from us is shaped directly with the developers we serve.
As the landscape evolves, we want to reintroduce what Privy can do today, and how teams across categories are already using it in production.
1. Privy is a low-level customizable API
Privy gives developers full API access and whitelabeled SDKs. Whether you use our components – or go fully custom – is entirely up to you.
You can use our SDKs or call our APIs directly to deliver a fully white-labeled product experience. Many of our customers mix and match – using out-of-the-box components, optimized through real-world usage across millions of users, while customizing frontends to maintain seamless, branded experiences.
Low-level control also means you can support multiple wallets per user, enable team wallets, or build entirely custom wallet flows on top of your own authentication system.
Our infrastructure adapts to your needs, not the other way around.
How teams are using Privy headlessly with our APIs:
OpenSea – the world's leading NFT marketplace
Uses Privy’s headless authentication and MFA functionality to onboard their users, and provision wallet behind the scenes, powering a seamless, secure onboarding flow for millions of users.
Echo.xyz – A community funding platform for startup founders
Similarly leverages Privy’s authentication feature set headlessly to fully customize onboarding and wallet creation, with no reliance on Privy’s UI. From onboarding to registering passkeys for MFA and multiple auth methods across EVM and Solana wallets, Echo has built all flows and UIs in-house, leveraging Privy under the hood.
Bankr – An AI-powered bot that deploys tokens and enables onchain actions via interactions on the social feed
Built entirely on Privy APIs to programmatically provision wallets and facilitate transactions from directly within the X feed. No front-end app needed.
2. Privy supports every chain out of the box
We support Solana, Sui, Hyperliquid, Stellar, and virtually any chain.
Privy supports every chain out of the box, with deep capabilities for EVM and SVM ecosystems, including Ethereum, Solana, Base, Arbitrum, Hyperliquid’s HyperEVM, and Eclipse.
Wallets are automatically configured with transaction signing and submission, smart wallet integration, event webhooks, and policy enforcement. For these chains, Privy also supports advanced features like embedded wallets, MFA, and session management.
We also eneable raw cryptographic signing with secp256k1 and ed25519 keys, enabling support for chains like Sui, Tron, and Stellar.
Whether you're launching a trading, social, or consumer app, Privy makes it easy to:
Manage keys across chains from a single interface
Build with simple, secure wallets across ecosystems
Future-proof your stack confidently, regardless of how your chain priorities evolve
We’re actively expanding support for new networks based on your needs. Please reach out – we’re here to help.
Here are some examples of apps building with Privy on different chains:
Moonwalk Fitness (Solana) – A walk-to-earn fitness rewards app that turns your steps into crypto
Users earn tokens for daily movement and can cash out rewards, all powered by seamless wallet creation with Privy.
Nexa (Sui) – A DeFi analytics platform for Sui
Combines deep onchain data with powerful trading tools, integrating Privy to onboard users and manage wallets natively within the app.
Kulipa (Stellar) – Issues branded crypto cards that let users spend directly with merchants
Uses Privy to hold user assets onchain, and liquidate them as they spend via card.
3. Privy has the capabilities to power trading and fintech, alongside consumer and social apps.
Trading platforms, neobanks, bots, and financial products rely on Privy every day.
Some of the biggest trading platforms today, like Hyperliquid, Pump.fun, and Jupiter, rely on Privy wallet infrastructure to power high-frequency trading, seamless bridging, and smooth mobile-first UX.
Here's what makes Privy trading-grade:
Ultra-low latency: Engineered for 20-100 millisecond performance at scale.
Enterprise-grade security: Combining key splitting and trusted execution environments gives Privy the ability to ensure the right custody setup with multiple failsafes across our systems.
Customer-signer controls: Add multiple signers per wallet to enable advanced use cases.
Granular policy engine: Set transaction thresholds, approve contracts, and restrict behavior per wallet.
We also offer trading-specific capabilities, including:
Embedded Hyperliquid trading: Privy serves Hyperliquid and integrates with the whole Hyperliquid ecosystem, with native support for their HyperEVM – enabling gasless trades, 0.07s block times, and up to 40x leverage.
Telegram + X bots: Run wallet-connected bots in chat or X via Privy’s API-level key management.
Key quorums: Configure the parties that have permission to control the wallet, including m-of-n arrangements for multi-party approval coordination.
Our infrastructure is shaped by the needs of the most demanding products. That means tighter security, faster performance, and more control for every builder and app using Privy.
