Introducing server wallets

We're opening up our underlying cryptosystem to offer you direct access to Privy's wallet APIs. Check out the server wallets section in your dashboard and docs to get started.

Welcome

Privy builds user onboarding and embedded wallet infrastructure to enable better products built on crypto rails. This means embedding asset control within applications themselves to enable users, businesses or machines to use digital assets through seamless product experiences.

Use Privy's client side SDKs to authenticate users, provision embedded wallets for them and prompt wallet usage. Use server wallets to securely manage digital assets at the application level directly from your server.

Using Privy

Broadly, Privy enables:

• User onboarding—Privy helps developers onboard users regardless of their experience with crypto-based systems. This means libraries to authenticate them, help them connect their existing wallets and provision self-custodial embedded wallets for them if they don't already have one.
• Wallet infrastructure—Developers can also directly access Privy’s bare-metal wallet APIs from their backend using server wallets to provision and manage cross-chain wallets for any use case.

Where embedded wallets run on user devices by default, server wallets reconstitute keys in secure enclaves controlled by the wallet owner. The private keys for both embedded and server wallets are never stored by Privy, encrypted or otherwise. Key splitting ensures flexible recovery systems for all use cases, bringing together enterprise-grade security and consumer-grade performance.

Engineering principles

At Privy, we believe technical decisions are moral decisions. Below are the principles that guide our engineering decisions.

Secure

Nothing is more important than your user's security. Privy’s key management system uses Shamir’s secret sharing to shard user’s private keys such that neither your app, nor Privy, can ever access a user’s keys. Keys are only ever reconstituted on the user’s device at the point of signing a message or sending a transaction.

Privy regularly undergoes rigorous audits to ensure your users control and privacy over their wallets.

Flexible

Privy gives your application low level access to users and their wallets to support a fully customized product experience. Your application can access Privy's functionality all the way down to the API level, supporting unique wallet flows including provisioning multiple wallets per user.

Easy to use

Privy has out of the box UIs so your app can support authentication and wallet flows in minutes. These UIs are highly customizable and can even be fully whitelabled. This means access to out of the box funding methods, smart wallet creation pipelines, and more.

Portable

Privy is compatible with any chain your application operates on. Your application can provision embedded wallets (or link external wallets to a Privy account) on Solana, Ethereum, and all EVM compatible chains. Privy is at the bleeding edge of distributed systems so when you want to build on a new chain, that chain is already supported.

With layers of customizability, Privy supports a wide range of product experiences.
