Abstract
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.
