Privy
Privy (Stripe)
Privy is embedded-wallet infrastructure that lets developers and fintechs integrate self-custodial wallets directly into apps and websites (Ethereum, Solana and other chains) without users managing seed phrases. Keys are reconstituted only inside secure environments (TEEs) and are never seen by Privy or the application. Based in New York, it was acquired by Stripe in June 2025, becoming part of its stablecoin and digital-asset strategy.

FAQ
Is Privy custodial?
No. Privy provides self-custodial embedded wallets: keys are reconstituted only in secure environments under the user's control and are not seen by Privy or the integrating application.
Can an individual use Privy?
Not directly: Privy is infrastructure that developers integrate into their products. As a user you typically interact with it unknowingly, through the app that uses it.
