Release of Canton 3.7.1 Canton 3.7.1 has been released on October 30, 2026. Summary This patch release introduces configuration options for GCP KMS key deletion notice periods. What’s New Minor Improvements • GCP KMS key deletion notice periods can now be configured via destroyScheduledD

The Validator App exposing the validator APIs is part of a CN Validator or CN Supervalidator node. It connects to a Canton participant and provides the following functionality: • It manages the Canton participant. Examples are automatically setting up the participant’s connection to Canton Net

Contrary to other assets like Eth or Bitcoin, Canton Coin requires a party to explicitly agree to hold Canton Coin. This includes explicitly agreeing to any incoming transfers. Parties that are ok with accepting incoming Canton Coin transfers from any sender, can setup a TransferPreapproval. This

Overview • See the text of the CIP-0056 for an overview of the APIs that are part of the Canton Network Token Standard V1. • See the text of the CIP-0112 for an overview of the APIs that are part of the Canton Network Token Standard V2. • See the README in its source-code for background on how to

This section describes deploying a Super Validator (SV) node in kubernetes using Helm charts. The Helm charts deploy a complete node and connect it to a target cluster. Requirements • DevNet (0.9.4) • TestNet (0.9.4) • MainNet (0.9.3) • A running Kubernetes cluster in which you have administ

This section describes how to deploy a standalone validator node in Kubernetes using Helm charts. The Helm charts deploy a validator node along with associated wallet and CNS UIs, and connect it to a global synchronizer. Requirements • DevNet (0.9.4) • TestNet (0.9.4) • MainNet (0.9.3) • A r

Networks There are three different networks: DevNet, TestNet and MainNet. If you are only interested in setting up a validator node, you can set up a node on DevNet for practice, then jump to MainNet. If you’d like to build, test, or deploy an app, we recommend that you run a node on DevNet, TestN

• DevNet (0.9.4) • TestNet (0.9.4) • MainNet (0.9.3) DevNet and TestNet get reset roughly every 3 months with the resets spread out such that they never happen at the same time on DevNet and TestNet. The exact time is announced in the #supervalidator-operations channel run by the Global Synchr

• DevNet (0.9.4) • TestNet (0.9.4) • MainNet (0.9.3) To initialize your validator node, you need the following parameters that define the network you’re onboarding to and the secret required for doing so. • MIGRATION_ID — The current migration id of the network (dev/test/mainnet) you are trying

There are three ways to recover from disasters: • In simple cases where only a single node is affected but the overall network is still healthy, a Restore from backup is usually sufficient. • If a full backup is unavailable but an identities backup has been created, the balance of the validator ca

For more involved debugging and disaster recovery, direct access to the console of a Canton node (participant, sequencer, mediator) might be required. Steps to obtain such access: Requirements: • Direct access to the Canton node process • Canton binary Once you see the following banner for the

The APIs below are published by Splice to aid decoupling different Canton Network applications. Consider using them to decouple your code from the upgrading cycles of your dependencies, when building Daml code that interacts with workflows of other apps in the Canton Network. These APIs are not man

There are two sets of HTTP APIs exposed by Splice applications, as can be seen in the diagram below: • The app_dev_scan_api are exposed by the Scan App of SV nodes and provides access to the view of the ledger and its infrastructure as seen by all SV Nodes. Use https://sync.global/sv-network/ to di

At a high level, participant nodes provide two separate endpoints through a Ledger API: • An endpoint to submit commands to the ledger that allow an application to submit transactions and change state, by creating, exercising or archiving contracts. • An endpoint that provides a stream of transact

Splice network applications and validators need to be able to connect to multiple supervalidators’ Scan apps and Canton sequencers. If you have the base URL for a single SV Scan app, you can query for all other connected Scans and the SV sequencers. This lets you dynamically update your app configur

dpm is the command-line interface for Canton development. It manages SDK installation, project scaffolding, compilation, testing, code generation, and local development environments. Most Canton development workflows start with a dpm command. Pre-requisites Dpm runs on Windows, macOS and Lin

A governance lock is a Canton Coin (CC) holding that is locked to fulfill the locking requirements for Super Validators (SVs) and Featured Apps (FAs). This page explains why governance locks exist, and how lock owners create and manage them with any wallet that supports CIP-0056 two-step transfers.
