SV governance UI/UX improvements

Development Fund Proposal Submission

Proposal file: /proposals/2026-06-FCS-splice-sv-ui-ux-improvements.md

---

Summary

This proposal clears 18 open issues from the SV governance UI backlog in canton-network/splice, delivering a complete shared component library, polished governance pages and operator-facing functionality improvements. The work reduces the maintenance burden on the Splice core team, improves the daily experience of every SV operator on the network and demonstrates that the Development Fund can drive upstream code quality through external contribution.

Notes for Reviewers

The 18 in-scope issues were recommended and selected through the Splice contributor channel, so the scope is already aligned with the Splice maintainers. Estimates are based on Digital Asset's own day-level estimates as a reference, validated and confirmed by FCS's engineering team. Timeframes include a one-week maintainer review and acceptance allowance per milestone, following guidance from the Splice maintainer DA team that milestones should reflect work that is reviewed and accepted, not only submitted.
