Privy is wallet infrastructure for applications that need to create, manage, and secure user wallets without forcing every user through a traditional external wallet flow. It combines embedded wallets, authentication, user management, signing, APIs, and policy controls.

Use it for:

• Creating embedded wallets for users or agents.
• Adding authentication and user account management.
• Managing transaction signing and wallet policies.
• Building programmable wallet flows from frontend SDKs or backend APIs.

Best fit: consumer apps, fintech products, games, marketplaces, AI agents, and platforms that need production-ready wallet infrastructure.
