Today, we're launching Tempo Zones on the Tempo Testnet. Every zone is private, fast, and interoperable with each other. Zones support MPP for private agentic payments at web scale. See interactive demo below.
Zones are also integrated in the Tempo Wallet - test it out at wallet.moderato.tempo.xyz. We have two zones live in our documentation for experiencing this on full force: docs.tempo.xyz/guide/private….
From a technical perspective, Tempo Zones are built on the Reth SDK and they have a few interesting innovations in them:
- Interoperability is solved by using the L1 as the pivot point, given fast finality this is really simple.
- L1 state is mirrored to the Zone, such as TIP20 tokens and their TIP403 policies.
- A stateless EVM executor which can be run inside a TEE or ZKVM for proof verification.
Overall very proud of our team's work on this and I think sets us up very well for interoperable, private and scalable blockspace.
Blockchains still broadcast every transaction publicly. Every stablecoin payment leaks the amount, the sender, and the recipient.
We’re excited to share that Tempo is building Zones for businesses that need privacy: private blockchains that are interoperable with the rest of Tempo for stablecoin use cases like payroll, treasury, and settlement.

Every ad impression, every recommendation algorithm, every retargeting pixel — all of it monetizes the space where human intent is unclear.
Agents collapse that space to zero.
An agent arrives with a mandate. Get me X. Budget Y. Constraints Z.
- No attention to capture.
- No desire to manufacture.
- No conversion funnel to optimize.
That's a different customer. And it needs a different internet.
- The attention economy monetizes the path to intent.
- The intention economy monetizes the *fulfillment of intent.*
At @tempo been building the protocol for that second economy — the Machine Payments Protocol, with Stripe, supported by Visa and others. Open source, designed for IETF standardization.
I wrote the full piece on what the intention economy looks like and why the infrastructure for it doesn't exist yet 👇
Normal create3 needs two keccaks to get the address (forwarder create2 → create nonce), this doubles the cost of mining vanity addresses over CREATE2
Have been nerdsniped for a while to build a better CREATE3, finally landed on something I think actually earns the v2

🧵 Tempo Architecture Deep Dive
@tempo is a payments-first L1 built for stablecoin transactions, whose testnet has launched a few weeks ago.
There are so many native features, but how will be the UX? What's the disadvantage?
In this thread, I'll break them down. 👇

Tempo’s testnet is live!
Any company can now build on a payments-first chain designed for instant settlement, predictable fees, and a stablecoin-native experience.
Tempo has been shaped with a wide group of partners validating real workloads including @AnthropicAI, @Coupang, @DeutscheBank, @DoorDash, @Lead_Bank, @mercury, @nubank, @OpenAI, @Revolut, @Shopify, @StanChart, and @Visa.
Since our announcement, @brexHQ, @Coastal, @crossriverbank, @deel, @faire_wholesale, @Figure, @GustoHQ , @Kalshi, @Klarna, @Mastercard, @Payoneer, @withpersona, @tryramp, and @UBS have also joined as design partners.
Dedicated payment lanes, stablecoin gas, deterministic finality, a built-in stable asset DEX, and programmable smart accounts are all live on testnet.
If you’re building or modernizing payment flows, you can start integrating and testing today.

ERC-7739.
A defensive rehashing scheme which prevents signature replays across smart accounts and preserves the readability of the signed contents.
tldr; enables smart accounts to sign signatures safely without vendor specific SDKs.
