Development Fund Proposal Submission
Proposal file:
/proposals/canton-transaction-debugger.mdSummary
A Canton-native Transaction Debugger that turns failed Ledger API submissions into human-readable diagnoses and shareable, privacy-aware debug bundles. It extends the existing Canton developer toolchain (Ledger API rejection payloads, correlation IDs, structured logs) rather than replacing any component, and reduces time-to-root-cause for privacy- and authorization-heavy failures from hours to minutes.
Checklist
/proposals/Notes for Reviewers
Label:
daml-toolingThis proposal is a single-objective debugger build. Scoped localnet replay is included as a small, bounded follow-on (Milestone 6) and does not gate MVP value or compete with the debugger objective. Funding is broken out per milestone with deliverables and acceptance criteria tied to ecosystem value (adoption, time-to-diagnosis, support load), not artifact delivery.
The team (InfraSingularity) ships Daml-based projects and operates production Canton validator infrastructure. Relevant SIGs: Daml Language & Developer Tooling, Canton APIs, dApp Integration.
Champion: TBD
Total funding request: 1,430,000 CC across 6 milestones (14 weeks).
