Development Fund Proposal Submission

Proposal file: https://github.com/joel-da/canton-dev-fund/blob/bd61f7b718fffa525d7b01d01e3a5fb496d9042d/proposals/2026-07-DA-user-paid-traffic-accounting.md

Summary

This proposal introduces participant node primitives for user-paid traffic accounting on Canton Network, along with an open-source reference Traffic Enforcement App that wallets can use or extend. It gives wallet and validator operators a reusable way to attribute, enforce, and manage traffic at the user level without breaking composability and reducing integration friction.
