Development Fund Proposal Submission
Proposal file:
/proposals/canton-cross-domain-settlement-reference-implementation.mdSummary
This proposal requests funding for an open-source reference implementation for cross-domain Delivery-versus-Payment settlement on Canton using Daml and TypeScript. It gives the ecosystem a reusable reference pattern for lock, reassignment, settlement, and recovery across synchronizer domains, building on an existing Daml prototype and extending it into a documented multi-domain orchestration flow.
Checklist
/proposals/Notes for Reviewers
This proposal is intentionally scoped as a reference implementation, not a universal settlement framework. Milestone 1 builds on an existing Daml prototype (
Lockable,DvPInstruction, and script scenarios), while the main funded work is hardening that primitive and proving real two-synchronizer orchestration, restart recovery, and rollback behavior in a reusable open-source form.Good Part of Prototype is ready for Milestone 1 and I can show it if committee need that.
