Add bootnode-canton-dappbooster-dev-stack proposal

Development Fund Proposal Submission

Proposal file: /proposals/bootnode-canton-dappbooster-dev-stack.md

---

Summary

dAppBooster for Canton v0.1 is an open-source local development stack (live today at github.com/BootNodeDev/cn-dappbooster) that takes a Canton dApp developer from Daml contracts to a working dApp UI on a laptop, including a self-custodial CIP-0103 browser wallet (Carpincho), and one-command local Canton infrastructure. This proposal funds the evolution of v0.1 toward its core thesis: Canton users installs one self-custodial wallet, creates their external parties within it, and uses those same parties to connect to any dApp on any validator. The keys never leave the wallet, the same identities work everywhere, and no dApp or validator can lock the user in.

Notes for Reviewers

• v0.1 is already running. Repo at cn-dappbooster, walkthrough at dappbooster.cc. One command brings the stack up. We are happy to walk anyone through it before review.
• Suggested labels: dapp-integration, wallet-apps.
• Still looking for a Champion
• The Rationale section states how we consume both PRs \#69 and \#90 (rather than compete), and Carpincho commits to passing PR \#69's Wallet Compliance Test Suite at v1.0.
