## Development Fund Proposal Submission

Proposal file: 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.

## 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.
