Abstract
Canton Upgrade Readiness Checker is an open-source CLI designed to validate whether validator and application deployment artifacts are ready for a Canton or Daml 3 upgrade. It scans configurations (HOCON, JSON, YAML, TOML), manifests, and topology-related inputs against a declarative rules engine, enabling teams to identify breaking changes, deprecations, and misconfigurations before production deployment. The tool follows a Rust-first CLI approach with YAML-defined rules that can be extended by the community as CIPs and upgrade guidelines evolve. It generates human-readable reports along with JSON outputs for CI integrations such as GitHub Actions and GitLab, allowing teams to block merges based on critical findings.
