Privy

Privy is a developer platform that provides wallet infrastructure for building financial products on top of digital assets. Its core purpose is to eliminate the complexity of blockchain integration, letting teams add embedded wallets, stablecoin payments, treasury management, and automated signing into their products without writing key management or custody logic from scratch.

The Problem Privy Solves

Integrating crypto into a real-world application involves a stack of hard problems: key management, recovery flows, signing policies, custody models, regulatory compliance, and blockchain-specific UX quirks. For consumer apps, the traditional seed phrase model causes significant drop-off. For business applications, managing keys at scale requires hardware security modules and internal policy enforcement. Privy abstracts both use cases behind unified APIs and SDKs, letting developers focus on their product rather than the underlying infrastructure.

How It Works

Privy's embedded wallets use a Shamir Secret Sharing (SSS) scheme backed by Trusted Execution Environments (TEEs). When a user creates a wallet, the private key is split into shares — none of which are held in complete form by any single party, including Privy. Authentication can be tied to email, social login, passkeys, SMS, or an existing external wallet, so users never need to manage a seed phrase directly. Signature requests happen in under 20ms from Privy's TEE infrastructure.

For developers, Privy exposes a REST API alongside backend SDKs in Node.js, Go, Ruby, and Python, and client-side SDKs for React, React Native, Swift, Android, and Unity. Server-side signing is supported through authorization keys and delegated signing, enabling back-end automation of wallet operations. A granular policy engine governs which actions can be taken, by whom, under what conditions — including multi-signature approval workflows and role-based access for organizations.

Products

Embedded Wallets are the foundational product. Wallets are provisioned at account creation using whatever authentication method the user prefers, with no browser extension or seed phrase required. These are designed for consumer-facing apps where smooth onboarding is critical.

Organization Wallets allow businesses to own wallets as entities rather than individuals, supporting multi-user ownership, approval flows, and business KYB verification. As of September 2026, Privy supports native KYB and fiat payout orchestration for organizations through its API.

Treasury Management is Privy's enterprise workspace, launched in September 2026, designed for finance and operations teams managing onchain capital. It provides a unified interface for transfers, multisig approvals, policy configuration, and automated workflows.

Agent Wallets support automated systems — AI agents, programmatic trading bots, and other backend processes — that need to sign transactions without human involvement. These wallets use server-side authorization and policy controls to define safe operational bounds.

Stablecoin and Payments Infrastructure layers on top of wallet primitives: fiat on-ramps and off-ramps, stablecoin card programs available in 25+ countries (via Stripe's infrastructure), universal deposit addresses, yield integrations, and bank account linkage for direct fiat-to-stablecoin transfers.

Supported Chains

Privy supports Ethereum and all EVM-compatible chains, Solana, and Bitcoin. Solana is a first-class integration — Privy's platform includes high-performance Solana transaction landing via Jito integration, supporting the low-latency, high-throughput demands that Solana applications require.

Stripe Acquisition and Scale

Stripe acquired Privy in June 2025 for an undisclosed sum. The deal followed Stripe's acquisition of Bridge, a stablecoin infrastructure firm, and positioned Privy as the wallet layer inside Stripe's broader stablecoin payments stack. Stripe's developer reach accelerated Privy's adoption: by mid-2026 the platform powers over 120 million accounts across more than 2,000 development teams and processes over 15 billion dollars in monthly transaction volume across 180+ countries.

Notable customers using Privy for production infrastructure include Deel (dollar-backed contractor payment accounts), the Majority neobank (USDC transfers on Solana between the US, Colombia, and Mexico), and AWS-integrated enterprise fintech deployments.

Security and Custody

Privy's infrastructure is certified with 99.99% historical uptime. The platform does not take full custody of keys — the SSS/TEE model means neither Privy nor the developer holds the complete private key. Custody flexibility is a documented design goal: businesses can choose from self-custody, delegated signing, fully custodial, and hybrid models depending on their regulatory environment and product requirements.

Solana Ecosystem Fit

Solana's high transaction throughput, low fees, and dominance in stablecoin settlement make it a natural home for Privy's infrastructure. The USDC-on-Solana corridor for cross-border payments (as demonstrated by Majority), the Jito integration for optimized transaction landing, and Privy's support for agentic use cases — AI agents executing Solana DeFi actions autonomously — all reflect how embedded wallet infrastructure translates into real Solana activity. As stablecoin and fintech adoption on Solana continues to grow, Privy represents a foundational layer for teams that want to ship products without managing the cryptographic complexity themselves.
