Proposal Appendix A, as shipped The 2026-03 grant proposal's Appendix A illustrated the developer experience this SDK would deliver, ahead of any of it existing. Some of it un

Talking to the Ledger API directly How the runtime types map onto the JSON and gRPC Ledger API wire formats when you skip the high-level clients. Back to the README. The highest-level path is the generated extension methods (IouSubmissionExtensions.TryCreateAsync, IouExtensio

API reference Public types of every packaged assembly, grouped by namespace. Start from the articles if you are new. Generated Ledger API wire types are not listed; see Wire-level types.

Getting started The SDK takes a Daml .dar archive to strongly-typed C# bindings, then submits them to a Canton ledger. This page is the short route; each step links to the full text. 1. Install the tools You need the .NET SDK 10.0.100 or later, a JDK 17 or later (for dpm codegen-cs), and dp

Ledger clients quickstart Resolve ICantonLedgerClient (from Canton.Ledger.Abstractions) from the container; the transport package you reference decides whether it speaks gRPC or the JSON Ledger API. Register a client dotnet add package Canton.Ledger.Grpc.Client service

Packages All 16 packages share one version and publish together. The README holds the authoritative package table; each package also has its own README: | Package | README | |---|---| | Daml.Runtime | README | | D

Canton .NET SDK Build .NET applications on a Canton/Daml ledger with full type safety. dpm codegen-cs turns a Daml .dar archive into strongly-typed C#, and one transport-neutral ICantonLedgerClient submits it over gRPC or the JSON Ledger API, with a PQS client, authentication, OpenTelemetry

Status, platform support and roadmap Where the SDK stands: release status, the OS and architecture CI covers, test coverage and what is planned next. Back to the README. Status Active. Curated public releases land here; ongoing development happens in a private development rep

Daml to C# type mappings How every Daml type maps to a C# type and a Daml.Runtime type, including the Optional, Numeric and Party edge cases. Back to the README. | Daml Type | C# Type | Runtime Type | |-----------|---------|--------------| | Int | long | DamlInt64

Canton .NET SDK Lets .NET applications talk to a Canton participant with full Daml type safety. The codegen generates strongly-typed C# from Daml .dar archives: a JVM-side helper wraps daml-lf-archive to decode a DAR into an intermediate representation, and a .NET-side emitter consumes that re

JVM codegen helper Scala/JVM binary that wraps daml-lf-archive to decode a .dar archive and emit an IntermediateDar protobuf message to disk. See JVM helper and AstToIntermediate translat

🚀 Canton .NET SDK: 0.7.1 TL;DR: a hardening release on the 0.7 line ✅: Daml.Codegen.CSharp.MSBuild is now published, so bindings generate at dotnet build time with no JDK needed ✅, and telemetry hides party, user and contract ids unless you opt in ✅. It also removes some API surface, so

🚀 Canton .NET SDK: 0.8.0 TL;DR: Canton 3.7: the clients target Canton 3.7.1 and support Canton 3.7 only. External-party onboarding accepts protocol version 37's v31 topology transactions. Canton 3.6 users stay on 0.7.x. 0.8.0 is a breaking release that opens the Canton 3.7 line on Canton 3
