Agents need credentials to do real work, but they don't have to hold them (and in fact, they shouldn't).

This is exactly why we built Turnkey Managed Secrets -- you shouldn’t have to choose between automation and control over credentials, and now you don't have to.

Don't let vibes write your threat model. We're making it easy to build the right way

Introducing Turnkey Managed Secrets!

For the first time, Turnkey is expanding our support for agents beyond wallets.

Managed Secrets allows teams to store, use and build automated access to sensitive secrets while keeping them protected from AI agents' context.

The next wave of stablecoin adoption will be driven by agentic payments, and @turnkeyhq is powering the guardrails that let agents move money securely at machine speed.

Had a great time talking about this on the @WalletConnect Payments Pulse

Your agents can now take actions on behalf of users without ever holding the credentials

Passwords, keys, and tokens never touch the agent's runtime or context

Soon this will be table stakes for enterprise buyers

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

Thrilled to have @archetypevc and @circle_ventures onboard as strategic investors, alongside the continued support from our long-term partners.

We’re moving from a world where value flows through systems designed for humans to one where it flows through systems designed for software.

Programmable money is becoming the default foundation for how economic activity happens online – across payments, coordination, and machine-to-machine transactions.

We’re building for when programmable systems become the primary interface for how value moves across the internet. $12.5M to scale faster.

Thrilled to announce a $12.5M strategic investment to meet accelerating demand for crypto wallets and verifiable computing.

With participation from @circle_ventures, @archetypevc, and existing investors @BainCapCrypto, @FactionVC, @galaxyhq, @sequoia, and @variantfund.
