01
Install
Run the command in your project. The CLI asks which agents to install for.
02
Describe the task
Ask your agent for something this skill covers. It loads canton-network-repos automatically when relevant.
03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

Version Mapping

Splice	Canton	DAML SDK	Protocol	LF Default	LF Available
0.5.4	3.4.9	3.4.9	PV34	2.1*	2.2 (verified)
0.5.3	3.4.8	3.4.8	PV34	2.1*	2.2
0.4.x	3.3.x	3.3.x	PV33	2.1	2.1

*Open-source Splice 0.5.4 ships with SDK snapshot 3.3.0-snapshot.20250502 (pre-dates LF 2.2). LF 2.2 was added to the SDK on 2025-10-03. Updating to SDK 3.4.9 enables LF 2.2 builds.

Key Configuration Files

Purpose	Repo	File
LF version definitions	daml	`sdk/daml-lf/language/.../LanguageVersion.scala`
damlc target validation	daml	`sdk/compiler/damlc/lib/DA/Cli/Options.hs`
Canton version	canton	`VERSION`
Built-in DARs	canton	`community/common/src/main/daml/`
Splice LF config	splice	`project/CantonDependencies.scala`
Package targets	splice	`daml/*/daml.yaml`
Docker builds	splice	`cluster/images/*/Dockerfile`

Splice LF config (project/CantonDependencies.scala):

val daml_language_versions = Seq("2.1")  // ← LF target; change to "2.2" for upgrade
val daml_compiler_version = sys.env("DAML_COMPILER_VERSION")

Package ID Derivation

Package IDs are cryptographic hashes of: source content + LF version (--target) + SDK/stdlib version + dependency package IDs.

Changing LF version = different package IDs = incompatible packages. Canton validates that upgraded packages use equal or newer LF version; mixing LF versions on the same ledger causes validation failures.

Enterprise vs Community Canton

Feature	Enterprise	Community
Transaction processing	Parallel	Sequential
Database	PostgreSQL, Oracle	PostgreSQL only
HA Domain	Supported	Embedded only
Pruning	Full	Limited

Build Commands

# Community Canton participant
cd canton && sbt "community/app/assembly"
# Output: community/app/target/scala-2.13/canton-community.jar

# Splice applications (requires DAML_COMPILER_VERSION env var)
cd decentralized-canton-sync && sbt compile

Upgrading to LF 2.2 (Verified with SDK 3.4.9)

project/CantonDependencies.scala: val daml_language_versions = Seq("2.2")
nix/daml-compiler-sources.json: { "version": "3.4.9" }
All daml/*/daml.yaml: set sdk-version: 3.4.9 and --target=2.2
Remove -Wno-ledger-time-is-alpha from all daml.yaml files (not in SDK 3.4.9)
Build: daml build -p daml/splice-util && daml build -p daml/splice-amulet

Community-built DARs have identical package IDs to enterprise at the same LF version (verified 2025-12-24).

Troubleshooting

"Unknown Daml-LF version: 2.2": damlc binary doesn't support 2.2. Check daml damlc --help for supported targets; upgrade to SDK 3.4.9.

Package ID mismatch: different --target values between builds. Check: unzip -p package.dar META-INF/MANIFEST.MF | grep Sdk-Version

Upgrade validation failed: swapping enterprise (LF 2.2) with community (LF 2.1) packages. Use DAR injection to maintain LF 2.2 compatibility.
