Announcing Turnkey’s $15M Series A

Let’s be honest — crypto is still too hard to use.

Before a user can do anything onchain, they have to jump through a series of hoops: download a browser extension, write down their seed phrase, and figure out how to approve a transaction for the first time. And because this happens before users even touch your product, it’s nearly impossible to get them to stay if something goes wrong.

Today, there is still a lack of proper infrastructure to address the crypto UX problem. But instead of approaching this problem from first principles, others are remedying it by creating shinier wallets and slicker UI components. None of this will onboard the next billion users when crypto’s fundamental UX issues stem from the inherent challenges of self-custody and securing wallets behind the scenes.

Turnkey is addressing the crypto UX problem from the ground up. We believe that developers shouldn’t sacrifice security and scalability for convenience, and that most infrastructure providers on the market today are too opinionated for developers to build seamless onchain experiences for their users.

Today, we’re thrilled to announce that we’ve raised a $15M Series A co-led by Lightspeed Faction and Galaxy Ventures, with participation from Sequoia, Coinbase Ventures, Alchemy, Figment Capital, Mirana Ventures, and more, to accelerate innovation in crypto. Our co-founders Bryce and Jack met while building Coinbase Custody into the largest crypto custodian in the world, taking it from 0 to $100B+ in assets. Jack then went on to become the CTO of Polychain where he led infrastructure for the $10B fund, and Bryce launched Trade Republic’s crypto product to millions across Europe. Our world-class team currently includes exceptional senior talent from Coinbase, Polychain, Parity, BitGo, and other top crypto companies.

Turnkey offers secure, flexible, and scalable wallet infrastructure for developers to build anything that involves a wallet or cryptographic transaction. This is the infrastructure necessary for crypto developers to bring more users and institutions onchain.

Most importantly, our infrastructure already powers some of the best developer tools and applications in crypto:

  • Alchemy has integrated Turnkey to provide embedded and smart wallet services as part of Account Kit

  • Dynamic offers mobile-first passkey embedded wallets to developers, powered by Turnkey

  • Thunder Terminal is embedding wallets directly with Turnkey-enabled biometric passkey logins, so that users no longer have to manually approve transactions for onchain trades

  • Kinto, a DeFi-focused L2 rollup, has built their onboarding experience entirely on Turnkey, so that users can take their first action onchain without ever touching a seed phrase

This isn’t coincidental—our focus on bespoke tooling and verifiable security is what enables companies like Halliday, Goldfinch, Squads, Terrace, Mural, and others to build web2-like experiences for their crypto product.

Turnkey believes that a true upgrade for web3 users doesn’t just entail making wallets more beautiful or simpler to use; it requires that we challenge preexisting notions of how we interact onchain entirely. It’s on us to build a decentralized future, and we’re excited to power the next wave of crypto products to accelerate this vision.
