We’ve spent years building infrastructure that protects crypto wallets. The more active agents get, the more we hear from customers that the same protections need to extend to the other credentials they rely on.
Turnkey Managed Secrets is our next step: bringing the secure foundation we built for private keys to API keys, passwords, and other sensitive credentials your agentic workflows use.

some of the best crypto companies started at YC (including my alma mater CB 💙). excited to see what comes out of this next batch!
we’re offering eligible YC teams $10K in @turnkeyhq credits over two years + help getting started.
building something in stablecoins, trading or agents? DM me.
At @ycombinator, we're excited to fund more crypto startups solving financial needs including AI capital raising, stablecoins, trading, and agents.
Here's our latest crypto request for startups. Our next application deadline is Monday.

Worked on this super closely with @prasincs over the last 12+ months. Him and the whole @Anchorage team have been the best alpha customers one can hope for.
Glad we can finally make some noise about this!
Key thing to highlight: attestation docs are used as proofs. Anchorage's HSMs (+ external wallets) trust Visualsign parser's output because they can verify the code that's generating it.
This pattern ("attestations as proof") is widely applicable...excited to see what people do! Code is open-source, go use it!
VisualSign makes transactions human-readable so users spot phishing before signing.
@Anchorage runs it on Turnkey Verifiable Cloud with @awscloud Nitro Enclaves, so every result carries attestation-backed proof of the code behind it.

Retail complains about delays, but rigorous testing is the exact reason why Ethereum has maintained 100% uptime since inception.
If u are building the global settlement layer for trillions in institutional capital, security and resilience are non-negotiable.

The Glamsterdam upgrade on Hoodi testnet previously scheduled for October 26th has been delayed. Node operators check your clients for instructions. The new date is TBA.

suddenly putting all the critical digital infrastructure code onto public blockchains so we can verify what is even going on, doesn't seem so strange. And going server-less. We should just put all the apps into blockchain code, too. So they run same every time. Switch not hard...

Introducing HSM Signing!
Our institutional customers require private key generation & signing inside their own environment in order to operate. Turnkey now offers self-hosted HSM signing and handles authentication, policies & transaction management beyond the signature.

A trading harness is the software that connects an AI system to the platform that executes trades. While volume on each harness tells you which are being used, it doesn’t tell you which will be the best fit for a given product.

.@UmbraPrivacy just launched the privacy layer for money.
Every user's viewing key is split across guardian nodes running on Turnkey Verifiable Cloud. No operator can see these keys, and anyone can verify that code onchain.

StageX is our answer to the reproducible build problem: a full-source, container-native toolchain that makes end-to-end reproducibility practical.
It starts from a minimal, auditable seed and progresses through 100+ reproducible build stages – each producing the next compiler, library, or utility.
Every stage is reproducible. Every output is verifiable. turnkey.com/end-to-end-repro…

.@sfwallet lets agents act on your behalf, within limits you set.
Built on Turnkey’s embedded wallet infrastructure, granular policies check each transaction at the signing layer, powering the guardrails for agentic money movement.

one thing we’ve been very intentional about at Turnkey is making our pricing work at every stage of a company’s growth. we price like an infrastructure company vs. taking a % of volume.
small teams can get started on our Pro plan at $99 per month.
larger enterprises moving serious transaction volume pay a fraction of a penny per signature.
we have the best engineers in the world building wallet infrastructure that scales with you from the first transaction to billions in volume.
if you’re building something interesting in crypto and need a partner that is:
- trusted by companies like Polymarket, Anchorage, Rain, Moonshot, and Modern Treasury
- built around secure isolated key management
- flexible across payments, trading and agentic use cases
- already powering millions of wallets and $200b+ in stablecoin volume
let’s talk.

Turnkey is on a very short list of crypto startups that are independent, have PMF, have amazing leaders and a great culture, and are continuing to ship relentlessly. I always recommend for folks to join and would be happy to refer folks if I know their work well.
and with that, another insane quarter at @turnkeyhq comes to a close
we officially crossed $200B in stablecoin transaction volume, just 9 months after crossing $100B.
the amount of money moving through our pipes has grown 4x YoY.
at the same time, we’re shipping faster than ever.
this month alone, we launched:
- cross-chain swaps
- onchain yield
- agent secret management
- Arc support from day one
and all of this sits alongside the stack we’ve already built across:
- stablecoin payments
- embedded wallets
- payment orchestration
- agentic wallets
- programmable signing + policies
- enterprise key management
what started as an idea to build better wallet infrastructure is becoming something much bigger.
we want Turnkey to become the layer behind how money moves onchain, whether it’s being moved by a consumer, enterprise, or even an AI agent.
we’re still so incredibly early.

A second factor enforced only in your app's UI isn't security. The UI isn't the boundary, and the API will still accept the request with one factor.
That's why we built it natively. MFA policies define what proof an action requires. Scoped Sessions define what the resulting session can do. Turnkey evaluates both on every request, at the layer that matters.
Here's how (and why): turnkey.com/blog/native-mfa-…

new thing we’ve been building at @turnkeyhq: agent auth.
agents need credentials to do useful work. right now this means giving them passwords, api keys, oauth tokens, even totp seeds. this gives the agent far more access than the action actually requires
for years, turnkey has secured millions of private keys using verifiable TEE infrastructure. underneath that is a generic system for credentials, auth and policies, with human and machine authenticators, consensus, temporary and revocable access, and a full audit trail
now we are opening up these primitives for agent builders.
the end user keeps sovereignty over their credentials while giving builders a way to easily grant scoped access based on the action it needs to take.
a lot of agent builders are not thinking about security yet, but we think this becomes a critical product differentiator very soon. we want to make doing it correctly the easy path.
many of the pieces are already live:
•agents can retrieve encrypted secrets under programmable policies, including consensus and temporary or revocable access
•they can sign git commits and authenticate over ssh without holding the underlying private keys
•and of course if you want your agent to pay for things over crypto rails, turnkey already secures the wallets and enforces the policies for that too
what’s next: we’re looking for agent builders who want to help shape what comes next. reach out or sign up below
