Problem Statement Today milestonex-campaign is single-campaign-per-instance. There is no contract-level multi-campaign registry. The deprecated core contract attempts multi-campaign (create_campaign returns an auto-incremented id) but is the wrong API/architecture.
Expected Outcome A new contract (or major revision to campaign/) that supports many campaigns in one instance, with:
create_campaign(creator, metadata) -> u64 returning a campaign ID.donate(env, donor, campaign_id, amount, asset) taking the campaign id.- Status transitions per campaign, scoped correctly.
- Reads/writes scoped by ID.
- A
MAX_CAMPAIGNS_PER_INSTANCE constant.
- Same typed-error space.
Acceptance Criteria
- New contract
milestonex-campaigns-registry (or equivalent) implements the API.
- Tests: 5+ concurrent campaigns, distinct counters, distinct statuses.
- Migration plan from single-campaign pattern is documented.
- Backward compatibility maintained (or a hardfork documented).
Implementation Notes
- This is a major feature; coordinate with roadmap.
- Reference the existing
common and campaign modular design to avoid duplicating logic.
