1/ At Privy, security isn’t a feature. It’s foundational.
We secure 75M+ accounts and power 500M+ txns/month across billions in volume.
Built on cryptographic infrastructure designed to enforce user custody, withstand compromise, and scale with risk.
2/ Secure architecture
Privy enforces user custody through distributed key sharding and secure enclaves (TEEs).
Keys are never stored in full and can only be reconstructed inside a TEE at the moment of use.
Not even Privy can access them. Only the rightful user can sign.
3/ Assume compromise
Privy follows least-access principles with hardened infrastructure, strict separation of duties, and zero standing permissions – even for internal teams.
Access is time-limited, fully audited, and enforced through architecture, not policy alone.
1/ Without strong auth, wallets are vulnerable, no matter how good the cryptosystem.
Privy’s embedded wallets protect access with 3 core levers:
1️⃣ Deep auth integrations
2️⃣ MFA + auth quorums
3️⃣ Policy-based defense in depth
Here’s how 🧵
2/ Every Privy wallet is generated inside a secure enclave and split by default (or can run on-device).
You choose how users authenticate to reconstitute the key:
✅ Privy auth (email, social, MFA)
✅ Third-party SSO (Auth0, Firebase, JWTs)
✅ Passkeys or custom signers in TEE
3/ Authentication is just the start.
Privy gives you fine-grained security controls:
✅ MFA (per session or action)
✅ Policy-based signing permissions
✅ Key quorums for multi-party approvals
1/ Today, we're proud to announce that Stripe is acquiring Privy.
We couldn’t be more excited.
Privy will continue as an independent product – but now we’ll move faster, ship more, and serve you even better, so you can stay focused on your users.
2/ We started Privy 3 years ago to make it easy for anyone to build better products on crypto rails.
That starts with better wallets.
At the time, wallets were powerful but inaccessible – built for power users and disconnected from real product UX.
3/ Privy abstracts that complexity away, making crypto feel like the rest of the internet:
✅ Simple
✅ Intuitive
✅ Instant
Today, we power 75M+ accounts across 1,000+ teams, enabling billions in transactions across wallets, apps, and users.
