Description.
Turnkey is a crypto infrastructure company founded in 2022 by Bryce Ferguson (CEO), Jack Kearney (CTO), and Sam McInvale, building verifiable key management and non-custodial wallet infrastructure for developers. The founding team met while building Coinbase Custody, scaling it to over $100B in assets under management, and designed Turnkey to fill the gap between institutional custody and developer-friendly infrastructure. Turnkey powers over 50 million embedded wallets and processes millions of transactions weekly across DeFi, payments, developer tooling, consumer apps, and AI agents. Notable clients include Bridge (a Stripe company), Polymarket, Moonshot, Alchemy, Magic Eden, World, Infinex, DIMO, Lightspark, and Rain.
Turnkey's infrastructure supports all major blockchains through a chain-agnostic, arbitrary signing approach based on cryptographic curves rather than specific cryptocurrencies. The company uses AWS Nitro Enclaves (Trusted Execution Environments) for all sensitive operations, ensuring private keys are never exposed outside secure enclaves. Turnkey has raised over $50 million in total funding, including a $30 million Series B led by Bain Capital Crypto (June 2025) with participation from Sequoia Capital, Lightspeed Faction, Galaxy Ventures, Wintermute Ventures, and Variant. The company has not disclosed any acquisition history.
Key Infrastructure.
Embedded Wallets
Non-custodial wallets embedded directly into applications for consumer, business, and AI agent use cases, with pre-built UI components via Embedded Wallet Kit and support for email, biometrics, social logins, and external wallet authentication.
Embedded Wallet-as-a-Service
White-labeled wallet infrastructure that platforms can distribute to their own customers and end users, with dedicated user accounts, platform-level controls, co-signing requirements, and full SDK/API customization.
Company Wallets
Programmatic onchain signing infrastructure for smart contract management and payment orchestration, with multi-signature approvals, scoped API keys, and granular policy enforcement for organizational workflows.
Key Management
Secure private key generation, storage, and access within AWS Nitro Enclaves with import/export capabilities, encryption key storage, and enterprise disaster recovery through policy-based wallet recovery.
Policy Engine
Fine-grained policy controls enforced inside hardware-isolated secure enclaves, allowing developers to define rules by address, asset, size, or approval flow with cryptographic proof of enforcement.
Turnkey Verifiable Cloud (Beta)
Verifiable cloud infrastructure that extends Turnkey's security model to cloud environments, enabling remote attestation and end-to-end reproducibility for critical operations.
Additional Features.
Sessions
Sign multiple transactions without additional approvals by creating user sessions with strict expiration and scoped policy controls.
Delegated Access
Enable scoped access to teammates, services, and AI agents with controlled session access without exposing private keys.
Transaction Broadcasting
Broadcast signed transactions to blockchain networks with optional gas sponsorship and rent sponsorship for supported protocols like Solana.
Pre-Generated Wallets
Streamline onboarding by generating wallets for users before authentication is completed.
OAuth & Passkeys
Flexible authentication via OAuth providers, passkeys, email, SMS, and social logins integrated directly into wallet creation flows.
Remote Attestation
Verify that the code running in Turnkey's enclaves matches the deterministically built source code through independent cryptographic attestation.
