Hi, all. Reminder about the upcoming Logical Synchronizer Upgrade slated for end of June (final date to be announced).

All party onboarding, package vetting and other topology transactions will pause for 24 hours before the LSU, and will resume immediately after the LSU completes.
Daml transactions will be delayed for seconds to minutes at the moment of the LSU
App providers should experience no other impact.

CIP-0116 Approved: Featured App Locking

CIP-0116 Approved: Featured App Locking

CIP-0116 has been approved, introducing CC locking requirements for Featured App designation on the Canton Network.

The goal is to make Featured App status more objective and market-based, while prioritizing applications that demonstrate committed capital and long-term alignment.

What this means for builders

Featured Apps must now meet clear onchain locking requirements to qualify for and maintain Featured App status.

This helps create a more transparent process for:
- Featured App eligibility
- Application prioritization
- Ongoing alignment with the network
- Governance around Featured App status

Builders and app teams can review the full proposal here:

Canton Builder MCP WalletConnect Update

Hey @Canton Builder
New Release for Canton Builder MCP to have Extended Info on WalletConnect Integration for Canton Guide.

Check it here: https://github.com/Jatinp26/Build-on-Canton-MCP

What's this? (for new builders here)
When developers use AI e.g Claude to learn Canton, they often get recommended deprecated documentation links. This Local MCP Integration solves that. It provides a curated, remotely updated knowledge base covering Canton's Dev Stack and Guide Devs using Claude 0 to 100.

The server fetches its knowledge base from this repo on startup, then caches it locally. If and when we push an update e.g WalletConnect, every MCP user gets it automatically on their next Claude restart, no manual pulls needed.

Canton Privacy Model: Confidential Transactions

Canton’s Privacy Model

Canton approaches privacy differently from most blockchains.

On the Canton Network, transaction data is only visible to the parties involved. The Global Synchronizer enables atomic settlement across applications without exposing details to uninvolved participants.

Participants choose what data to share, with whom, and under what conditions.

For regulated financial markets, this is what makes the difference between infrastructure institutions can actually use and infrastructure they cannot. @Announcements

Canton 3.4 to 3.5 Upgrade Plan

CANTON 3.4 TO CANTON 3.5 TRANSITION

Update: 2026-04-24

See details in the long-term SV Operations schedule

Phase 1: Splice 0.5.x releases pause, and multiple new Splice Daml models go into effect
- The Splice 0.5.x release line is complete

Daml Models and configuration settings going live on MainNet in Phase 1:
- Development Fund Manager Party is now live on MainNet as of April 15th.
- CIP-0104 Traffic-based App Rewards Increments 2 and 3 are in effect on MainNet
- May 5th: Daml models from Splice 0.5.16 go live on MainNet. All Validators must upgrade to Splice 0.5.16 on MainNet before this date.

Phase 2: Splice 0.6.x Release line. Splice 0.6.x begins to introduce features from Canton 3.5 as part of the standard bundle. Protocol-breaking changes remain behind feature flags.
- Splice 0.6.0 had errors in early testing by SVs on DevNet.
- Splice 0.6.1 will be released to SVs on Monday, April 27th.
- Validators should not upgrade until at least Tuesday, April 28th.
- Splice 0.6.x will introduce Logical Synchronizers, along with the ability to upgrade between two physical synchronizer nodes while preserving the same Logical SynchronizerID
- This will allow protocol-changing upgrades to take place without pausing Daml transactions. Topology transactions, like adding new nodes, onboarding parties, and vetting Daml models, do pause during protocol-changing upgrades.

Major Milestones for Splice 0.6.x:
- April 27th: Splice 0.6.1 goes live on DevNet. Logical Synchronizer introduced.
- April 30th: Validator Liveness Rewards reduced to zero (0).
- Late May:* Super Validators practice an upgrade using a Logical Synchronizer (aka Logical Synchronizer Upgrade / LSU) on DevNet. No actual protocol changes will be introduced in this practice.

Phase 3: Upgrade Global Synchronizer networks to Canton Protocol 35
- After proving out Logical Synchronizer upgrades on Splice 0.6.x, all three Global Synchronizer networks will perform a Logical Synchronizer upgrade to Canton protocol Version 35.
- Final timing and numbering of this upgrade, and the specific Canton 3.5 features to be included along with it, is still TBD. New features will roll out over time, relying on LSUs to minimize impact on Node Operators and App Providers.

Major Milestones for Phase 3:
- Early June: LSU on DevNet introduces protocol upgrade and major new features. TestNet LSU follows one week later.
- Mid-June: LSU on MainNet introduces protocol upgrade. New features introduced, following the same feature flags and upgrade procedures introduced on DevNet and TestNet.

Canton Network 3.4→3.5 Transition Update

ENTERING CANTON 3.4 TO CANTON 3.5 TRANSITION PERIOD

Starting this week, Canton Network enters a period of transition from Canton 3.4 to Canton 3.5.  This will introduce a series of significant new features on DevNet, TestNet and MainNet.

The transition will take place in multiple phases:
Phase 1: Splice 0.5.x releases pause, and multiple new Splice Daml models go into effect

Splice 0.5.18 is now available on DevNet, and will roll out to TestNet and MainNet over the coming two weeks.
- This will be the final feature release of the Splice 0.5.x release line. If issues are found in this release, Splice 0.5.19 will contain patches. If issues are found in this release, a Splice 0.5.19 release will be created that will contain patches only.

Daml Models and configuration settings going live on MainNet in Phase 1:
- April 15th: Development Fund Manager Party changes from null to a value
- April 20th: CIP-0104 Traffic-based App Rewards Increments 2 and 3:

- These features will roll out to TestNet and MainNet over the coming two weeks, arriving on MainNet April 20th
- This enables API support for precise traffic costs per transaction (as used for application reward attribution), earlier than the original plan of mid-May.
- Increment 4 is currently on track to be available on MainNet by the end of June.
- May 5th: Daml models from Splice 0.5.16 go live on MainNet. All Validators must upgrade to Splice 0.5.16 on MainNet before this date.

Phase 2: Splice 0.6.x Release line. Splice 0.6.x begins to introduce features from Canton 3.5 as part of the standard bundle. Protocol-breaking changes remain behind feature flags.
- Most important: Splice 0.6.x will introduce Logical Synchronizers, along with the ability to upgrade between two physical synchronizer nodes while preserving the same Logical SynchronizerID
- This will allow protocol-changing upgrades to take place without pausing Daml transactions. Topology transactions, like adding new nodes, onboarding parties, and vetting Daml models, do pause during protocol-changing upgrades.

__Major Milestones for Splice 0.6.x: __
- April 27th: Splice 0.6.0 goes live on DevNet. Logical Synchronizer introduced
- April 30th: Validator Liveness Rewards reduced to zero (0).
- Late May: Super Validators practice an upgrade using a Logical Synchronizer (aka Logical Synchronizer Upgrade / LSU) on DevNet. No actual protocol changes will be introduced in this practice.

Phase 3: Upgrade Global Synchronizer networks to Canton Protocol 35
- After proving out Logical Synchronizer upgrades on Splice 0.6.x, all three Global Synchronizer networks will perform a Logical Synchronizer upgrade to Canton protocol Version 35.
- Final timing and numbering of this upgrade, and the specific Canton 3.5 features to be included along with it, is still TBD. New features will roll out over time, relying on LSUs to minimize impact on Node Operators and App Providers.

Splice 0.5.16 Daml Model Upgrade

:Alert: Attention :Alert:

Splice 0.5.16, coming to DevNet on March 23rd, introduces new Daml models that will impact some exchanges and applications.

Action:
All exchanges and wallets that parse AmuletRules_Transfer transactions directly must either update their parsing methods to the new transfer workflows, or move to CIP-0056 token standard transfers.

All application developers who directly depend on splice-amulet models older than version 0.1.17 must recompile to a version greater than or equal to 0.1.17.

The Daml models requiring these changes will take effect on the following dates:

DevNet: Apr 7, 2026
TestNet: Apr 21, 2026
MainNet: May 5, 2026

Details in the Splice Release Notes: https://docs.dev.sync.global/release_notes.html#release-notes

CIP-0105 Approved SV Locking Framework

CIP-0105 Approved: SV Locking & Long-Term Commitment Framework

CIP-0105 has been approved.

This proposal introduces a voluntary, onchain framework allowing Super Validators (SVs) to demonstrate long-term commitment to the Canton Network.

How it works

Super Validators may choose to lock a portion of their lifetime earned $CC rewards.
The more rewards locked, the greater their forward SV Weight.

Locked tokens vest gradually over 365 days.

Why it matters

As the Canton Network becomes more visible to external markets, governance must rely on cryptographic proof of alignment, not reputation alone.

CIP-0105 ensures governance influence accrues to those demonstrating real, long-term commitment to the network.

Canton Network: Third-Party Apps & DYOR Notice

Canton is an open network. Users are free to connect wallets and interact with Featured Apps or non-Featured Apps of their choosing. The Foundation does not curate or designate “approved” tools across the broader ecosystem, nor does it gate who can deploy applications to the network.

As always, users should exercise their own judgment and perform appropriate due diligence before interacting with any third-party application—especially those that have not been formally introduced or documented by the teams behind them.

To put this in perspective: you wouldn’t go to Ethereum to complain about something happening on Arbitrum, or to Solana to complain about pump fun. The same principle applies within the Canton ecosystem—individual dApps operate independently and are responsible for their own products and services.

If you require support for any ecosystem dApps, please contact the official support channels of that specific application. The main Canton Telegram channel nor main Discord chats cannot provide support for third-party dApps.

If an app seeks Featured App status or formal recognition, that process is public and transparent and will be clearly communicated to the community. App specific business models and user commercials are not determined or implemented by the Foundation.

As always, DYOR (Do Your Own Research) before interacting with any application or protocol within the ecosystem.

Canton Network: March 31 Fork and Fee Updates

Three important updates:

Batched and Weighted Featured App Markers ~~are live on MainNet as of last week (Splice 0.5.11)~~. Coming March 31st to MainNet. This will make it possible to replace App Markers with a single weighted marker setting a weight equivalent to the nominal traffic cost of the transaction. Multiple markers will be be processed as a batch. Implementing weighted and batched markers reduces your total transaction cost, speeds up transaction processing, and makes more bandwidth available across the network.
- This is an intermediate step on the path toward traffic-based app rewards (CIP-0104).

Free confirmation responses went live last week. This means that if your node hosts parties that are involved in transactions that they do not submit, your node does not need to pay a traffic fee to submit confirmation responses for those transactions.

Fork coming March 31st. Splice 0.5.11 introduces Daml models that will fork any node that does not upgrade to at least 0.5.11 before those Daml models go live. These models were previously scheduled to go live yesterday, but that has been delayed until March 31st to resolve a bug in a dependent process on the Sequencer

Built for the real financial system

Many blockchain networks launch quickly and evolve over time.

Canton was built over more than a decade and tested against real market constraints with institutions like DTCC, J.P. Morgan, and Goldman Sachs, alongside the firms that move trillions through the financial system.

This is not a pilot.

It is real infrastructure designed for the real financial system. @Announcements

Security Advisory: Secrets in Validator Logs

Security Advisory — Potential secrets exposure in validator logs

We have identified an issue where sensitive credentials (such as your PostgreSQL password and Ledger API auth token) may be written in plaintext to validator application logs. This only occurs under a specific combination of conditions described below.

Who is affected?
You may be affected if both of the following are true:
1. Your validator deployment uses additional DARs beyond the standard Splice dars, AND you deployed those dars via the .appDars Helm value OR by manually setting the SPLICE_APP_DARS environment variable to a non-null value. (Uploading additional DARs via other means does not make you affected.)
2. DEBUG-level logging is enabled for the validator app.
- Helm deployments: DEBUG logging is on by default.
- Docker Compose deployments: The default log level was changed from DEBUG to INFO in Splice 0.5.10.

What should I do?
1. Immediately ensure your validator app log level is set toINFO or above. This stops any further exposure.
If you believe your deployment matched both conditions above, we recommend rotating the following secrets:
- PostgreSQL database password
- Ledger API auth token
- Any other secrets you may have added as environment variables on the validator app deployment

Fix
This issue has been resolved in splice#4230 and will be included in the upcoming 0.5.14 release.

Canton Network: Privacy and Institutional Scale

Privacy and Institutional Scale on Canton

Privacy is a core requirement for institutional deployment.

Canton’s network-of-networks architecture supports horizontal scaling through independent synchronizers and dynamic traffic routing.

As activity grows, institutions can introduce additional synchronizers to expand capacity without creating central bottlenecks.

This design enables sustained, institutional-scale operation on the Canton Network.

Shaul Kfir explains the model and its implications in detail.

Splice 0.5.13 Notice: Scan Script Deprecated

:yellow_alert: Attention :yellow_alert:

Splice 0.5.13, which will be available on DevNet next week, deprecates the sample python script, scan_txlog.py, that has until now provided a reference for how to download and parse the Scan /updates stream. This script will no longer be maintained, and will be removed in a future release. Developers interested in understanding how to parse transactions from history should refer to the documentation for Reading and parsing transaction history involving Token Standard contracts.

DAML MODEL UPGRADE ISSUE impacting PQS users

The following DAML package versions were introduced by Splice 0.5.11, and are effective on DevNet as of this week.

name version

amulet 0.1.16

amuletNameService 0.1.17

dsoGovernance 0.1.22

validatorLifecycle 0.1.6

wallet 0.1.17

walletPayments 0.1.16

These Daml model versions are currently scheduled to go live on TestNet (March 3rd) & MainNet (March 10th).

However, Splice 0.5.11 deployments this week on TestNet have exposed an issue where in certain cases, "uploaded but not-yet vetted" packages break some assumptions in PQS. In order to avoid these issues, validator operators that use PQS are advised, as part of the 0.5.11 deployment, to make the following configuration changes:

  • in k8s, set the Helm value on the validator app maxVettingDelay to 0m
  • in docker-compose, add to the validator container an environment variable  ADDITIONAL_CONFIG_MAX_VETTING_DELAY with value canton.validator-apps.validator_backend.max-vetting-delay = 0m

Scaling Canton Apps with Wallet Interoperability

New Blog: Scaling Canton Apps with Wallet and App Interoperability

We just published a new post outlining a proposed standard to improve wallet and app interoperability across the Canton Network.

Burn-Mint Equilibrium (BME) on Canton

Canton chose a different path in crypto: Burn-Mint Equilibrium.

  • 100% of network fees are burned
  • Fees are fixed in USD, so usage translates directly into burn, regardless of narratives

The point is simple: if utility keeps compounding, the burn keeps compounding too, even in a sideways macro.

Check out the clip for the clearest explanation of BME dynamics and why the market may still be underpricing what’s happening on Canton, explained by Wes. @Announcements
