JUST IN: The Zenith EVM Testnet is live and open to the public. For the first time, 31800+ Ethereum developers can deploy standard Solidity applications that compose atomically with @CantonNetwork - the institutional blockchain where DTCC, JPMorgan, Goldman Sachs, and Visa process $9T+ in monthly settlement volume. Point your existing tools at the Zenith RPC endpoint and deploy. Your contracts don't change, your tooling doesn't change, and every transaction is finalized through Canton's consensus with deterministic finality in seconds. The external_call() primitive enables atomic composability with Canton-native Daml workflows directly, and the Linked Transactions explorer shows you the full lifecycle of every transaction across both environments in one place. Zenith is already contributing to two of the most significant tokenization initiatives running on Canton: @The_DTCC 's DTC Digital Assets Solutions Industry Working Group bringing $114 trillion in U.S. securities on-chain, and @progmat_en's Tokenized JGB working group targeting Japan's $1.6 trillion JGB repo market alongside MUFG, Mizuho, and BlackRock Japan. This is the first public venue where Ethereum's programmability and Canton's institutional rails meet. Get started: docs.zenith.network Explore: explorer.testnet.zenith.netw… Full announcement: zenith.network/resources/blo… To test atomic cross-environment workflows with the Zenith Gateway, reach out to us directly: partners@zenith.network Zth.

Moving a DeFi protocol to @CantonNetwork takes more than translating its code from Solidity to Daml. Protocols that rely on a global state have to be rethought for a network built around privacy. Zenith Head of Ecosystem @GArentoft explains the problem in a new episode of Tokenization Talks with @haumicharts, and why Zenith takes a different route: Solidity applications deployed on an EVM environment inside Canton’s consensus, where they can interact with Canton-native assets. Chapters worth jumping to: > 06:25 How Zenith connects Ethereum applications to Canton > 10:42 Daml, privacy and the developer challenge > 15:10 Canton super validators and governance > 20:33 Can Canton build a retail ecosystem?

Zenith is among the co-sponsors supporting IBC's contribution to @lfdecentralized, alongside individuals from Wells Fargo, Figure Markets, OpenZeppelin, Partior, Cardano Foundation, and other industry leaders. Look at who's coming together around open blockchain interoperability. Banks, public blockchain ecosystems, digital asset infrastructure providers, and security companies are backing an initiative that brings IBC under neutral Linux Foundation governance. And for us, this goes beyond supporting an open standard. Zenith is actively working with the @cosmos team, with IBC already integrated into Zenith Testnet. This lays the groundwork for cross-chain communication and asset transfers between Zenith and IBC-connected networks, extending interoperability beyond the Canton ecosystem. IBC has facilitated $50B+ in transaction volume across 200+ networks. Its move to neutral Linux Foundation governance opens the door to broader collaboration across financial institutions, blockchain ecosystems, and infrastructure providers. As institutional finance expands across different execution environments, interoperability becomes increasingly important. We're excited to be contributing to that work both through industry collaboration and technical integration. Zth.
Zenith is pleased to support the Inter-Blockchain Communication Protocol (IBC) contribution to @lfdecentralized, the home of open-source blockchain tech used by the world’s largest banks and financial institutions. Since 2021, IBC has facilitated $50B+ in transaction volume across 200+ networks, enabling secure asset and data transfers between independent ledgers. Today, we welcome this step by @Cosmos and 22 other organizations to create a more connected financial ecosystem. Find out more: prnewswire.com/news-releases… Zth.

Every extra settlement boundary is another way for a transaction to end up half done. Bridges and messaging between chains create those boundaries, because each leg finalizes separately. Atomic composability removes them by letting every step, across every application and asset involved, commit in a single transaction. Zenith builds this into the architecture. Every EVM block is created inside a @CantonNetwork transaction and finalized by Canton consensus rather than by an independent validator set, so Solidity applications and Canton-native assets settle together, with deterministic finality and no reorgs. Zenith EVM testnet is live, try it out: docs.zenith.network/zenith-t… Zth.
One transaction. Two apps. One outcome. On Canton, the cash leg and the asset leg settle together or not at all. No half-finished trades, no bridge in the middle. That's what the Global Synchronizer does. @CantonNetwork @ZenithFdn

Settlement risk lives in the gap between two legs of a trade. Atomic settlement removes the gap, because both legs commit in the same transaction or neither does. @CantonNetwork built that into how institutions settle. Zenith brings EVM execution inside it, so lending logic and DeFi applications written in Solidity can act on Canton-native assets without splitting the settlement. The JGB collateral lifecycle we validated locally for @progmat_en's working group is one example of the flow: zenith.network/resources/blo… Zth.
One transaction, two apps, one outcome. On Canton, one transaction can move cash in one app and an asset in another. Either every action in it commits, or the whole transaction is rejected. (1/6)

October moved institutional tokenization on @CantonNetwork from announcements to operations. Our October Canton Signal recap covers the month: • @The_DTCC's Tokenization Service went live, with Canton and DTCC’s private Besu network integrated at launch and 20 DTC participants signed • @Uber tested keeping corporate cash invested over a weekend with HSBC, Franklin Templeton, Tradeweb and Fireblocks • DRW and @MarexGlobal completed an OTC swap on Canton using Derivnex • Universal Burn (CIP-0129) was approved • Zenith validated a JGB collateral lifecycle across Canton and Zenith EVM on a local stack, and joined the @ERC3643Org and Digital Assets Associations The question we’re watching next: what gets built on top of this infrastructure now that the assets are live. Read the full recap. Zth.

A tokenized asset becomes liquid when there is somewhere for it to be used. Zenith Co-Founder & CBO @HeslinKim was on stage at @AIBC_World in Rome with @totofinance, @MIDAODS and @prypcocom, working through what is actually trading, what is simply parked, and what it takes to build a real market around a real asset. For Zenith, the answer lives in the application layer: lending markets, collateral facilities and trading venues that tokenized assets can plug into. That is the part Zenith EVM brings to @CantonNetwork. Zth.
Yesterday at @AIBC_World, our CEO Steven Gaertner (@stevengae_06) took the AIBC Stage to tackle one of the biggest questions in RWA: Tokenized Everything, Traded by Nobody: The Liquidity Problem RWA Keeps Avoiding Alongside @MIDAODS, @ZenithFdn and @prypcocom, the panel dug into what’s really trading, what’s simply parked, and what it takes to build real liquidity around real assets. Our view is simple. Tokenizing an asset is the easy part. Building a real market around it is where the work begins. That’s why we started with copper, an asset the world already needs. Thanks to @AIBC_World for hosting and to our fellow panelists for a sharp conversation. Missed it? Come find us at Booth H7-7184, Hall 7 🇮🇹

How much could institutional finance gain from unlocking 200+ days of limited collateral access each year? That's the scale of the opportunity @HeslinKim explores at @rwasummitglobal in Singapore: making tokenized Japanese government bonds accessible beyond traditional market hours, opening the door to DeFi lending, stablecoin liquidity, and new yield strategies. And we've been testing the infrastructure behind that vision. In our recent technical case study, Zenith locally validated an end-to-end JGB collateral lifecycle across @CantonNetwork and Zenith EVM, from issuance and atomic settlement to Solidity lending, repayment, and liquidation. Using JGB-representative assets, the pilot demonstrates how institutional collateral workflows can interact with Ethereum-compatible financial applications. Watch Heslin's take and explore the technical case study: zenith.network/resources/blo… Zth.

Japan’s JGB repo market is estimated at about $1.6 trillion, a market where faster settlement and programmable collateral could improve efficiency, liquidity and access. We carried a tokenized JGB through every stage of its collateral lifecycle. As part of our contribution to @progmat_en's JGB working group alongside MUFG, Mizuho, BlackRock Japan, and State Street, we validated the full cycle across @CantonNetwork and Zenith EVM: 1. Issue: the JGB is created on Canton with holder eligibility and transfer controls written into the contract, so the rules stay enforceable for the bond’s whole life. 2. Buy: the bond is purchased with stablecoins in an atomic DvP, so delivery and payment commit together and neither side is left waiting. 3. Borrow: the bond stays locked on Canton, so it can’t be used twice, while an ERC-20 representation is deposited as collateral in a Solidity lending protocol on Zenith EVM and a stablecoin loan is drawn against it. 4. Monitor: Canton reads the loan’s health from the EVM against a block hash it recorded itself, without trusting whoever reports it. Margin calls and liquidation triggers follow from those readings. 5. Resolve: if the borrower repays, the bond is released. If the loan falls below its threshold, the collateral is liquidated and the bond passes to a new owner, subject to a holder-eligibility check on the receiving party. The pilot ran on a fully local stack, and the public Zenith EVM Testnet is where developers can now build with Canton and EVM together: docs.zenith.network/zenith-t… Full breakdown: zenith.network/resources/blo… Zth.

Uber’s pilot on @CantonNetwork shows that cash can keep earning yield and still be there the moment a payment is due. The solution, built with @HSBC, @FranklnTempletn, @Tradeweb and @FireblocksHQ, let @Uber buy tokenized money market funds with HSBC Tokenized Deposits, with the ability to liquidate part of the holding outside market hours, including over a weekend, without giving up yield in the meantime. It works because cash and fund shares settle together in a single synchronized step, without relying on a public bridge. That kind of connected settlement is what Zenith brings to Ethereum’s application layer. Zenith EVM lets Solidity applications and Canton-native assets finalize in one atomic transaction, which could open tokenized assets like these to lending, liquidity and other DeFi use cases. The Zenith EVM Testnet is live for developers who want to build toward that. Deploy Solidity contracts with the Ethereum tools you already use, with EVM blocks finalized through Canton: docs.zenith.network/zenith-t… Zth.
.@Uber completed a first-ever pilot of an onchain liquidity and settlement solution on Canton, a public network. Working with @HSBC, @FranklnTempletn, @Tradeweb and @FireblocksHQ, Uber liquidated part of its holdings, even on a weekend, while earning yield until disbursement.

The Zenith EVM Testnet reset is complete and the network is live again with the protocol upgrade. Everything starts fresh: balances, contracts and transaction history have been wiped, so it’s a clean slate for anyone building. To get back to building: • Re-fund your wallet from the faucet: explorer.testnet.zenith.netw… • Redeploy your contracts • RPC endpoints and network settings are unchanged, so your existing configuration still works The upgrade brings a protected faucet, fairer rate limits and a round of fixes and hardening based on what a month of public testing surfaced. Our docs have been refreshed alongside it, so take a few minutes to look through what’s new before you deploy: docs.zenith.network/zenith-t… Thanks to everyone who builds on the testnet and helps make it better. Zth.
Thanks to everyone who has been building on and testing Zenith EVM Testnet. The Zenith EVM Testnet will be reset on Monday, 2 Nov 2026, between approximately 2pm and 5pm CET (13:00 to 16:00 UTC), to ship a protocol upgrade, performance improvements and network hardening. What the reset means for you: • All testnet state will be wiped: balances, deployed contracts and transaction history. • Re-fund your wallet from the faucet once the network is back. • Redeploy your contracts after the reset. What’s changing: • Faucet bot protection: The faucet is now protected by a captcha, so bots and spammers can’t block real users from getting tokens. • Stricter faucet rate limits: Claims are now more tightly rate-limited, so funds are spread fairly among builders and testers. • Per-block transaction cap removed: The previous limit on transactions per block is increasing too. • Fixes and hardening: This upgrade includes fixes for issues discovered on the current testnet, plus general stability improvements. A note on testnet ZTH: All existing testnet ZTH balances, including any previously farmed ZTH, will be gone after the reset. Testnet ZTH has no value, and farming it provides no benefit. The faucet exists so developers can test, and the new protective measures are there to keep it that way. Network details: We expect RPC endpoints and other network settings to stay the same. If anything changes, we’ll update our docs accordingly. Expect some downtime during the upgrade. We’ll post here as soon as the network is live again. For more info about our testnet, please visit our docs: docs.zenith.network Zth.

A nine-to-five market leaves bond collateral difficult to access for 16 hours a day, plus weekends and public holidays. What changes when those assets become available 24/7/365? @HeslinKim walks through what changes when tokenized bonds are accessible around the clock. The bond can be posted as collateral in established DeFi lending infrastructure, a stablecoin can be borrowed against it, and that stablecoin can be put into a tokenized money market fund, one of the most broadly accessible RWAs today. The bond keeps its place as collateral while the borrowed cash earns in a separate position. Ethereum already has an established ecosystem of programmable financial applications. Canton brings institutional assets and the controls governing their use. Zenith EVM connects these capabilities, enabling Canton-native financial workflows and EVM smart contracts to participate in the same atomic transactions. Zth.
Weekends. Public holidays. Overnight closures. What if your bond collateral could keep working? Heslin Kim (@HeslinKim), co-founder and CBO of Zenith (@ZenithFdn), walks through the possibilities: use tokenized bonds as collateral, borrow stablecoins, and put those funds to work in tokenized money market funds.
