Proposal: Canton Auth Dev Harness

Development Fund Proposal Submission

Proposal file: /proposals/canton-auth-dev-harness.md

---

Summary

This proposal requests funding for Canton Auth Dev Harness, a focused open-source toolkit for local JWT/OIDC development and testing in Canton applications. It standardizes local auth setup, test-token generation, claims presets, integration examples, and CI-ready fixtures so teams do not have to rebuild the same auth scaffolding in every project.

Notes for Reviewers

This proposal is intentionally narrow and scoped to avoid overlap with broader deployment, admin-console, and wallet efforts.

It focuses on one repeated workflow gap after node setup: local auth-enabled development and testing. The deliverable is a reusable harness for JWT/OIDC startup, test-token generation, claims presets, middleware examples, CI fixtures, and diagnostics for common misconfiguration cases.

The main differentiators are:

• focused on local development and integration testing, not production auth hosting
• centered on reusable token, claims, and middleware workflows rather than user-management UI
• useful across multiple Canton app teams without changing protocol behavior
• priced and scoped as a focused public-good developer tool
