Privy API
Privy — authentication and embedded wallet infrastructure for web3 apps, enabling users to sign in with social accounts or email and get a non-custodial wallet automatically, with a REST API for user and wallet management.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
SOC2 Type II. Private keys sharded with MPC — Privy cannot unilaterally sign transactions. Non-custodial by design. App Secret for server auth. Hardware security modules for key storage.
⚡ Reliability
Best When
Your agent application is web3-native and users need wallets automatically provisioned on sign-up without the friction of external wallet setup.
Avoid When
Your app doesn't need blockchain wallets — traditional auth providers (Clerk, Auth0) are simpler and cheaper.
Use Cases
- • Agents managing user authentication in web3 apps where users need wallets without managing seed phrases
- • Embedded wallet creation — agents provisioning wallets for users programmatically via Privy's server-side API
- • Cross-chain identity — agents reading user wallet addresses across multiple chains from a unified Privy user identity
- • Social login + crypto — agents enabling Google/Apple sign-in that automatically creates a blockchain wallet for users
- • Server wallets — agents using Privy's server-managed wallets to sign transactions programmatically without private key management
Not For
- • Non-web3 applications — use Auth0 or Clerk for traditional web auth without blockchain requirements
- • Self-custody wallet power users — Privy embedded wallets are custodial by design
- • High-frequency blockchain transactions (>1000 tx/min) — server wallet throughput may be limiting
Interface
Authentication
App ID and App Secret for server-side API. Client-side uses JWT user tokens. Authorization header with Basic auth (App ID:App Secret). User-level tokens for client SDK operations.
Pricing
MAU-based pricing. Server wallet transactions may have additional per-transaction fees at scale. Competitive with Magic and Dynamic for web3 auth pricing.
Agent Metadata
Known Gotchas
- ⚠ Server wallets require separate setup from embedded wallets — different API endpoints and permissions
- ⚠ Privy user IDs are Privy-internal — agents must map to app-level user IDs via linked accounts
- ⚠ Embedded wallets are tied to Privy — migrating off Privy means users lose access to embedded wallets
- ⚠ Social login linking requires user interaction — agents cannot programmatically link accounts without user consent flow
- ⚠ Chain support varies — check current supported chains before building multi-chain agent workflows
