Development Fund Proposal Submission
Proposal file: https://github.com/BlockXAI/canton-dev-fund/blob/canton-streams/proposals/canton_streams.md
---
Summary
GrowStreams is an open-source payment streaming primitive for Canton that makes continuous financial obligations flow the way they actually accrue, instead of settling in monthly batches. It provides Daml smart contract templates, a TypeScript SDK, CIP-103 dApp API integration, and CIP-56 compliant settlement for LP incentive programs, node operator billing, vesting schedules, consortium revenue distribution, and USDCx settlement flows. Unlike previous streaming proposals to this fund, GrowStreams enters the review process with demonstrated demand: 4,300+ participants in our Canton launch campaign in under 24 hours, 7,233 upvotes on the CCTools ecosystem directory, 1,317 registered users, and 66/66 tests passing on Canton 3.4.11 with six institutional use cases live.

Notes for Reviewers
Champion: Srikant Label: financial-workflows-composability
CCTools (the most recently approved Dev Fund project) is our active integration partner. Our joint Canton launch campaign generated 4,300+ participants in 24 hours. The campaign is live and verifiable at https://www.cctools.network/earn/growstreams-x-cctools. Our platform at growstreams.xyz has 1,317 registered users and 3,078 on-chain quest completions. The CCTools ecosystem directory shows 7,233 upvotes and 8,905 views.
The technical proof is in the repository. 66 consecutive test passes on Canton 3.4.11, six working institutional use cases, terminal output in /evidence/. Any committee member can clone the repo and reproduce the results.
We are not connected to PR #94 and not competing with it. We are open to collaboration if the committee considers that useful.
