Development Fund Proposal Submission
Proposal file:
[proposals/cantonflow-visual-builder.md](proposals/cantonflow-visual-
builder.md)
Summary
This proposal requests funding for CantonFlow, a visual BPMN builder for
Canton that lets teams design workflows in a Camunda-compatible modeling
environment and compile them into Canton-native Daml applications. The project
aims to reduce the barrier to building multi-party workflows on Canton by
combining BPMN-based design, BPMN-to-Daml transpilation, deployment tooling,
and a constrained AI-assisted workflow drafting experience.
Checklist
/proposals/Notes for Reviewers
Please review the proposal as a deliberately scoped Phase 1 ecosystem tool
rather than a full enterprise workflow platform. The proposal explicitly
prioritizes transpiler correctness, CBP-v1 compliance, BPMN round-trip
compatibility, and LocalNet/DevNet deployment over broader BPMN semantics,
advanced analytics, and large-scope security audit work.
