Turnkey, a leading provider of secure, flexible, and scalable crypto wallet infrastructure, today announced $30 million in Series B funding, bringing the company's total funding to more than $50 million.
Bain Capital Crypto led the round, with participation from Sequoia Capital, Lightspeed Faction, Galaxy Ventures, Wintermute Ventures, and Variant.
Since launching in 2022, Turnkey has become the engine behind millions of onchain transactions, enabling developers to embed secure, scalable wallets directly into their products. Its customers include Bridge (a Stripe company), Magic Eden, World, Alchemy, Polymarket, and more.
“Usability and security issues with crypto wallets have held back crypto adoption," said Bryce Ferguson, CEO and co-founder of Turnkey. "If you want people outside of tech enthusiasts to use crypto, you need to make crypto wallets as easy and secure as popular payments apps like Venmo or CashApp. That's what we're focused on at Turnkey: building infrastructure for the best possible crypto wallet user experience, and powering the adoption of crypto for generations to come."
Fintech and crypto companies globally have adopted Turnkey’s programmable crypto infrastructure. Developers can use Turnkey's API and open-source SDKs to integrate crypto wallets into their apps, automate complex signing workflows at scale, and implement granular policy controls. Turnkey's core technology differentiator lies in offering the first verifiable key management system of its kind, as detailed in the company's 2025 white paper.
Turnkey has raised its Series B funding after achieving a number of technological and business milestones, including:
• Onboarding customers across DeFi and trading, developer tooling, payments, and consumer applications. Scaling the number of signed transactions across Turnkey embedded wallets to millions weekly.
• Open sourcing QuorumOS, the operating system for Turnkey's end-to-end verifiable computing environment.
• Launching dynamic wallet infrastructure for AI agents using trusted execution environments.
"In the three years since launching, Turnkey has become an industry-leading solution for creating embedded wallets, signing transactions, and automating onchain actions," said Stefan Cohen, Partner at Bain Capital Crypto. “Many of the world's fastest-growing crypto and fintech companies are now using Turnkey because its key management platform offers the most secure and scalable way to incorporate critical crypto infrastructure into their products — from adding non-custodial wallets to enabling fast transaction signing and automating complex signing workflows. We look forward to working with the Turnkey team as they scale significantly in the years ahead."
“Turnkey is a trusted infrastructure technology partner to Polymarket,” said Mike Shrieve, Head of Research at Polymarket. “As the world’s largest prediction market with millions of dollars in daily USDC volume, we’re building for scale and longevity. Turnkey’s flexible key management infrastructure gives us the foundation to grow confidently and securely.”
With this new funding, Turnkey will grow its team across engineering, product, marketing, sales, and operations as it expands its global presence.
