Big news: We’ve raised a $30M Series B led by @BainCapCrypto to power innovation in crypto!

We’ve pioneered verifiability, led the conversation, shipped products, and written the docs. Still wondering if it’s valuable or how it actually works? Here’s your guide:

We’ve landed in Abu Dhabi for @solana’s Breakpoint! Excited to discuss payments, wallet infrastructure, key management, and verifiability with the builders shaping the future of web3. Hosting an event? What shouldn’t we miss?

5/ These SDKs deliver native performance, consistent APIs, and secure transaction handling out of the box – so you can integrate wallets, signing, and onchain features quickly and reliably, whether you’re targeting a single platform or multiple devices.

4/ Flutter SDK: Cross-platform widgets & methods let you build consistent experiences on iOS & Android with a single codebase. https://t.co/GpHMoMEohY

3/ Swift SDK: Updated iOS & macOS SDK makes wallets, transaction signing, and on-device security seamless for Apple platforms. https://t.co/ITEZr20Y0s

2/ Kotlin SDK: Add native Android support for wallets, transaction signing, and key management with minimal boilerplate and maximum reliability. https://t.co/HeqmGADGyj

1/ With these new + reworked SDKs, developing onchain apps is more accessible & user-friendly. Repetitive boilerplates and platform differences can slow teams down and increase the risk of bugs – Turnkey is simplifying all of that.

Building onchain apps across devices just got easier! We’ve launched our Kotlin SDK, and made major improvements to our Swift & Flutter SDKs. Build secure, seamless onchain experiences across Android, iOS and macOS.

Check out CEO @sadbryce on Episode 6 of The Financial Loop tomorrow at 16:00 UTC!

@coinbase 🔗Get started:

Introducing @coinbase x402 payments support! Instantly integrate Coinbase x402 with your Turnkey Embedded Wallets & run onchain payments directly in your app! A lightweight middleware handles signing - no browser extensions, no friction. Just seamless onchain pay-per-use flows.

2/ “Turnkey just delivers where it matters most – secure key management, flexible infrastructure, and email-based wallet recovery. No bloat or unnecessary complexity involved.” - @jaysonhobby

1/ See how they simplified private key management and shipped fast with Turnkey: – $1M+ saved vs. building in-house – 9 months of development time saved – 100% of users covered by self-serve account recovery https://t.co/0dhl0DIVrR

Congrats to @jaysonhobby and the @legendapp team on their launch! Legend Labs is bringing onchain finance to the mainstream with a fully non-custodial DeFi superapp that feels as simple as web2. Secured by Turnkey.

New SDK example for @tempo’s public testnet is live! With Tempo x Turnkey, you can: - Sign + broadcast transactions with raw payload signing - Support gas sponsorship using the same flow https://t.co/xXGn4VqTMa

5/ This builds on top of Turnkey’s existing work in provable crypto workflows: verifiable wallet creation and Turnkey Verifiable Cloud, trusted by early adopters like @Anchorage. Now, developers can further verify that critical workflows run exactly as intended.

4/ Developers can confirm that the enclave is running the expected policy engine software, ensuring signing and access activities are authorized as intended, in an isolated, secure environment.

3/ Verifiable Policy Decisions gives you cryptographic proof that your policies have been evaluated correctly, and the decisions permitting signing and access actually ran in isolated, secure enclaves.

2/ Without a verifiable binary, you’re trusting that authentication and signing rules are being applied correctly. Developers need proof.

1/ Turnkey’s policy engine governs how signing and access are evaluated. Well-designed policies at the signing layer enforce strict rules on who can authorize transfers and which contracts can be called. But, there are massive trust assumptions that come with policies alone.
