Canton Network Repositories Repository Hierarchy 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): 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.
