JUST IN: Zenith has completed its next major technical milestone on the path to full EVM composability on @CantonNetwork Mainnet.
Earlier this year Zenith demonstrated the first atomic transaction flows between EVM applications and Canton. Today that goes further, a fully atomic swap between a Canton-native CIP-56 asset and an ERC-20 asset on Zenith, executed through a Canton-native application on a feature-complete test network, between a Canton-only user with just a partyID and a Zenith-only user with just an EVM account. Neither party required knowledge of the other's environment.
At the core is external_call(), a new primitive now merged into Canton's repository that allows Daml contracts on Canton to invoke Solidity contracts on Zenith from within Daml workflows, settling multi-leg operations atomically through Canton's Global Synchronizer. The foundation for full EVM composability at the protocol layer is laid. external_call() is scheduled for rollout to Canton Mainnet as part of the Canton 3.6 release in late Q3 or early Q4 2026.

I give up 54 days a year where I don’t have dinner with my family, where I don’t put my 2 year old daughter to bed, and where I’m starting my day at 9AM and finishing work around 11PM so I’m also not seeing my wife — in order to join Canton’s weekly Tokenomics, Governance, and Ecosystem Fund calls.
That’s 15% of my year where I give up my evenings to join voluntary governance meetings.
We are a startup. We are a 14 person startup at that. We don’t have the luxury of not participating and not having our voices heard.
And I give up that 15% so I can keep the lights on for the 13 other people in our team who rely on our business for their livelihoods, to spend time their family and friends, and to make sure they have a stable and predictable career with us.
We’ve committed to @CantonNetwork more than just several millions of dollars in company treasury to build @ZenithFdn, but also our time. Not just working hours, but our lives. It’s not just me on these governance calls. It’s 4 of my other teammates as well to make sure we have full coverage. That’s 35% of our company contributing to Canton governance on multiple calls per week, roughly 25 hours.
We’ve earned our position in the network. We deserve our position in the network. It has not been easy. At all.
This is commitment, and this is how we get things done.

Zenith doesn't just build on @CantonNetwork, it helps govern it.
As a Tier-1 Super Validator with maximum weight - earned through Canton's CIP process based on demonstrated contribution - Zenith participates directly in the decisions that shape how the network evolves. Beyond validator operations, Zenith's team holds active seats across Canton Foundation committees, the bodies that translate governance into practice.
Tech & Operations Committee @NorbertVadas: protocol standards, network upgrades, and the developer tooling that underpins Canton's infrastructure.
Tokenomics Committee @HeslinKim, @NorbertVadas, and @GArentoft: the economic decisions that shape $CC issuance, rewards distribution, and how value flows through the network. Heslin sits as one of 8 voting members and also on the Protocol Development Fund, the body responsible for evaluating and funding contributions to Canton's core infrastructure. Gustav brings five years of governance experience from Stable Labs to the committee.
Accountability Committee @Henrixbor: milestone verification, SV compliance, and reward escrow oversight. The enforcement layer ensuring governance commitments are met.
Marketing Committee @SuontamaJulia: how Canton communicates its ecosystem development to the broader market.
Across these committees, Zenith's team participates in the technical standards, economic decisions, governance enforcement, and ecosystem communication of a network that JPMorgan, DTCC, Goldman Sachs, and Visa depend on for live production operations. That presence is what building for the long term actually means.

JUST IN: Zenith internal test environment has crossed 500,000+ EVM transactions
Every transaction routed through @CantonNetwork, executed atomically with 100% success rate and 1.5sec average latency on an entirely unoptimized stack. The number keeps climbing and the Beta Testnet isn't even live yet.
What makes this milestone is what happened under the hood. Both Canton and EVM legs committed simultaneously within the same consensus mechanism with no timelocks, no window of exposure, and no bridge assumptions. The protocol guaranteed the outcome. Half a million times, it held.
This is what consensus-level atomicity looks like in production: explorer.zenith.network/

Cross-chain infrastructure has a vocabulary problem. The word "Atomic" appears in bridge protocols, HTLC swaps and interoperability solutions of every kind. It's being used to describe mechanisms that deliver fundamentally different guarantees, and the industry isn't being precise enough about the difference.
> Economic atomicity is what most bridges and cross-chain swaps deliver. The smart contract guarantees an all-or-nothing outcome at the application layer, but both legs still settle on separate chains through separate consensus mechanisms. The guarantee depends on both parties behaving rationally within timelock windows that are measured in hours. When a validator gets compromised, a chain reorgs, an attacker locks counterparty capital and simply waits, the smart contract can't protect against any of it. The window of exposure between two separate settlement events is where the damage happens.
> Consensus-level atomicity is what Zenith delivers. Both legs of a transaction are processed within the same single consensus mechanism as one indivisible operation. There is no window and no timelock. The protocol itself guarantees that both legs commit together or neither does, regardless of what either party does or what the infrastructure beneath them does.
For consumer applications that distinction is manageable, but for institutional finance moving real capital across chain boundaries, it's the difference between infrastructure you can depend on and infrastructure that works until something goes wrong.
The EVM execution adds a few hundred milliseconds to Canton's native finality time, that's the entire overhead. Compared to timelock windows measured in hours, the latency difference alone changes what's possible to build.
We wrote the full breakdown about two flavours of atomic that are worth understanding clearly before you build on either: zenith.network/resources/blo…
