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.

if you’re an enterprise fintech adding stablecoins, choosing the right wallet infrastructure provider is one of the most important decisions you’ll make
here are 6 reasons why you should use @turnkeyhq:
1. we already power hundreds of enterprise customers including @polymarket, @raincards, @stablecoin, @moderntreasury, @anchorage and @flutterwave
2. we’ve processed over $200b in stablecoin transactions across 150M+ wallets
3. we offer sub-100ms signing built for high-volume payment flows
4. our architecture keeps private keys from ever being exposed
5. our APIs and SDKs are built to make integration as simple & flexible as possible
6. our engineering team works closely with you to help you ship at scale
if you’re looking for a stablecoin infrastructure provider that will work 1:1 with your team as you start your crypto journey, send me a DM
happy to chat

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
To access the beta or follow along: turnkey.com/agent-auth-beta
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

"They don't care about this" is a sad state of affairs for TEE apps/devs. Conclusion: almost all of them use TEEs as a "security badge", without reproducible builds.

(reminder: remote attestations are _useless_ without reproducible builds: quorum.tkhq.xyz/posts/remote…)
----
IT DOES NOT HAVE TO BE THIS WAY! This is a clear tooling gap IMO, and @turnkeyhq is solving this:
- StageX made reproducible builds easy: quorum.tkhq.xyz/posts/reprod…
- Turnkey Verifiable Cloud (TVC) solved the infra + key management portion of TEE deployment: docs.turnkey.com/features/ve…
- Simple template to start using TEEs correctly: github.com/tkhq/tvc-template

Excited to bring Upshift vaults to @turnkeyhq
Turnkey powers 50M+ embedded wallets and millions of onchain transactions every week. Now, wallets built on Turnkey can make institutional-grade yield accessible directly where users already hold and manage their assets.
Distribution unlocked such that yield is natively available inside the wallet.
Congrats to the Turnkey team on Earn launch — excited to build together.
August USDC V2 vault is available through @turnkeyhq Earn from day one.
Teams building on Turnkey can switch the vault on and their users earn USDC yield in-app. It lends USDC on @Morpho against Upshift vault receipt tokens and other collateral.
Composable Earn, live in Turnkey.

Introducing Swaps and Earn on Turnkey!
Your users can now trade assets and access onchain yield right inside your product, with top-tier rates and an expansive selection of vaults.
Set your own fee on both, and turn onchain activity into new revenue.

Building the guardrails for agentic commerce is a trillion dollar opportunity.
When Visa (BankAmericard back then) first launched in the 50s, they airdropped tens of thousands of already active credit cards to consumers that hadn't applied to them.
As you can guess, fraud went completely out of control with consumers and merchants and they lost millions of dollars. Instead of killing the experiment, they doubled down on infrastructure AROUND the cards: underwriting, collections, fraud controls, dispute resolution. Figuring out these problems led to the biggest consumer payments network EVER.
The same will happen with agentic payments. The industry is building a massive honeypot and new types of fraud and errors will happen that we never expected. We can't just copy and paste what we did in card networks to agentic. To control machine-based payments, we need new machine-based controls: cryptographic verifiability, escrow contracts, strict access policies, and human-in-the loop approvals. It's going to be a wild ride.

When your agent needs to fill out sensitive info, our policy engine (running in TEEs) checks the request, ensures it has enough approvals, exports it to the broker which injects it to the exact field the secret was cryptographically bound to at creation
The consensus policy seen below required human approval. Turnkey's programmable policies allow encoding semantics like allow-once or allow-always dynamically into policies. (iOS approval app SOON)

Bitcoin is great because it lets anyone convert their salary directly into a high-compounding equity position without massive systemic and operational risk, zero-sum games, or having to take an all-in entrepreneurial leap.
It’s the only exit built for normal people.

If you aren't staking your BTC... why?
