Development Fund Proposal Submission
Proposal file: proposals/canton-launchpad.md
Summary
Canton Launchpad is a visual LocalNet control plane for Canton - a one-click desktop app that shows real-time synchronizer connection state on a React Flow topology canvas, decodes JVM/gRPC exceptions into plain-English diagnostics, and reduces sandbox iteration time from ~10 minutes to seconds via snapshot/restore. It directly implements the "Network Topology Visualizer" the Canton Foundation's own DevEx Survey named as a missing tool.
